The present invention relates to a cosmetic, pharmaceutical, preferably dermatological, composition or homecare product comprising or consisting of a specific lipophilic active component and an effective amount of 1,2-heptanediol and/or 2,3-heptanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols and the use of said compositions as a cosmetic, for personal care, as a pharmaceutical, for animal care or for homecare. Additionally, the present invention relates to the use of 1,2-heptanediol and/or 2,3-heptanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols for improving the solubility of a specific lipophilic active component in a cosmetic or pharmaceutical composition. Finally, the present invention relates to the use of 1,2-heptanediol and/or 2,3-heptanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols as solubilizer replacer in a cosmetic or pharmaceutical composition or homecare product.
Cosmetic, personal care, dermatological pharmaceutical preparations or homecare products are complex mixtures intended to be applied to the external parts of the human body or for laundring, washing and cleaning purposes. In the long list of ingredients are included lipophilic active components. A broad spectrum of lipophilic active components are extensively used in a wide range of cosmetic, personal care, or pharmaceutical preparations to serve a variety of functions, such as anti-inflammatory, anti-itching, anti-redness, anti-dandruff, anti-microbial, anti-perspirant, anti-cellulite, anti-viral, anti-oxidative, anti-wrinkle, skin-whitening, skin tanning, pain-reducing, swelling reduction, skin barrier strengthening, anti-mycotic, anti-sagging, deodorant and skin soothing properties, etc.
The drawback of these lipophilic active components is their poor water solubility. Their poor water solubility makes it difficult, to incorporate these components in aqueous, aqueous/alcoholic or aqueous/glycolic formulations such as gels, liquid soaps, shampoos, gels, etc. and even in emulsions. The incorporation of these components becomes more difficult with increased water content of the aqueous, aqueous/alcoholic or aqueous/glycolic formulations. Due to their poor water solubility, it is in particular difficult, to prepare clear and non-turbid formulations such as solutions for wet wipe, micellar water, mouth wash, after shave, cleansing solution, hair tonic, hair and body mist, facial serum, facial toner, deos, etc.
In order to improve the solubility of lipophilic active components or ingredients in cosmetic and pharmaceutical compositions or homecare products, solubilizers are widely used. A solubilizer is an ingredient that helps solubilize, i.e. make soluble, an ingredient which is otherwise insoluble in a medium. The best and most widely application of a solubilizer is to solubilize and to uniformly incorporate, i.e. dissolve, a lipophilic component, such as an essential oil, into a water-based formulation.
A solubilizer is neither a dispersant nor an emulsifier although all three solubilizer, dispersant or emulsifier belong to the surfactant family. An emulsifier helps two immiscible ingredients blend to an emulsion, for example to make an O/W or a W/O emulsion. The created emulsion usually has a particle size in micrometer range and appears milky. With an emulsifier, the dispersed phase has a concentration (depending on the emulsifier) between 1 to 80%. The two immiscible ingredients are usually water and plant oils, fatty esters, waxes or fatty acids.
Solubilizers are similar to emulsifiers in that they have both hydrophilic and lipophilic traits, but solubilizers tend to be completely water soluble and only a little oil soluble. In practice this means they can suspend smaller amounts of oils. With a solubilizer, the dispersed phase has a particle size in nano-meter range and because they are solubilizing only small amounts of lipophilic active substances, the overall solution can still appear clear or lightly hazy.
Usually essential oils, fragrance oils or preservatives with oil soluble components (such as benzyl alcohol) or other lipophilic active substances in water (or hydrosols) are solubilized. The concentration of the to-be solubilized ingredients is usually between 0.01 to 5.0%.
Dispersants are somewhere between solubilizers and emulsifiers. They can disperse very low concentrations of oils (such as vitamin E or even a triglyceride) in water. They don’t completely solubilize the oil though; the product is not completely transparent. They disperse the oil in a translucent to milky solution which remains stable for a reasonable period of time.
Apart from the appearance, there is a safety and functional problem with such formulations. In a uniformly solubilized product, the lipophilic active ingredients are uniformly dispersed in the product as very small droplets and their concentration is exactly the same through the whole solution from the very first splash to the very last ml till the bottle is completely empty. Without the use of a solubilizer the distribution of the lipophilic active ingredient, would be quite haphazardly in the solution and would vary from application to application.
Solubilizers are commonly used in water-based formulas such as aqueous, aqueous alcoholic, aqueous glycolic preparations, gels, liquid soaps, shampoo but also used in products such as bath oils, tonics, and room sprays. They are also used to stabilize suspensions and prepare colloids and gels.
However, solubilizers have different negative side effects like increased foam formation. This behaviour is undesired in non-surfactant based formulations. Often they are based on ethoxylated fatty alcohols which have negative side effects on the skin since they increase the skin permeation.
In addition, the current interest in “natural” cosmetics has turned the attention of the cosmetic chemist back to improved versions of the classical raw materials or natural and renewable raw materials, i.e. which are sustainable.
Thus, there is still an ongoing need to provide further substances which can improve the solubility of lipophilic active ingredients in topical compositions, and thus, increase their availability in the composition, and which do not have the above described negative aspects of commonly used solubilizers.
When searching for agents improving solubility it must be taken into account that the substances used in the cosmetic or pharmaceutical sector must be toxicologically acceptable, well tolerated by the skin, stable, especially in the customary cosmetic and/or pharmaceutical formulations, substantially and preferably odourless and able to be preferred inexpensively, i.e. using standard methods.
However, there is no clear dependency between the chemical structure of a substance, on the one hand, and its capability in improving solubility, on the other hand, which makes the search for suitable substances more difficult. Furthermore, there is no predictable relationship between solubility improvement, toxicological acceptability, tolerability and the stability of a substance.
It is therefore an object of the present invention to provide a cosmetic or pharmaceutical composition, in particular dermatological, or homecare product, comprising or consisting of a lipophilic active component which has an improved solubility in the cosmetic or pharmaceutical composition or homecare product.
A further object of the present invention is to provide a cosmetic or pharmaceutical composition or homecare product, which is stable, i.e. in which the lipophilic active component remains solubilized and in which undesired crystallizing-out or precipitation of the lipophilic active component or undesired turbidity of the composition is prevented even when stored over long time.
It is another object of the present invention to provide a substance, which improves the solubility of a lipophilic active component in a cosmetic or pharmaceutical composition or homecare product.
Furthermore, it is an object of the present invention to provide a substance by which the amount of applied solubilizer in a cosmetic or pharmaceutical composition or homecare product can be reduced, i.e. a substance which is suited as a solubilizer replacer.
Surprisingly it has been found that the addition of an effective amount of 1,2-heptanediol or 2,3-heptanediol or a mixture comprising 1,2-heptanediol and 2,3-heptanediol or a specific alkanediol or a mixture of two or more different specific alkanediols as defined herein to a topical composition comprising a lipophilic active component significantly improves the solubility of said lipophilic active component.
It has been observed that the overall amount of solubilizer in a topical composition comprising a lipophilic active component can be significantly reduced by the addition of an effective amount of 1,2-heptanediol or 2,3-heptanediol or a mixture of 1,2-heptanediol and 2,3-heptanediol or a specific alkanediol or a mixture of two or more different specific alkanediols as defined herein.
Additionally, it has been found that the addition of an effective amount of 1,2-heptanediol or 2,3-heptanediol or a mixture of 1,2-heptanediol and 2,3-heptanediol or a specific alkanediol or a mixture of two or more different specific alkanediols as defined herein to a topical composition comprising a lipophilic active component reduces foam formation.

The present invention is specified in the appended claims. The invention itself, and its preferred variants, other objects and advantages, are however also apparent from the following detailed description in conjunction with the accompanying examples and figures.
In a first aspect, the present invention relates to a cosmetic or pharmaceutical composition or homecare product, comprising or consisting of:
Alternatively, the present invention relates in a first aspect to a cosmetic or pharmaceutical composition or homecare product, comprising or consisting of:
In a further alternative, the present invention relates in a first aspect to a cosmetic or pharmaceutical composition or homecare product, comprising or consisting of:
In a preferred variant of the first aspect of the present invention, in the three alternatives defined above, the component (b) is different to the component (a).
In a second aspect, the present invention relates to a cosmetic or pharmaceutical composition or homecare product, comprising or consisting of:
In a preferred variant of the second aspect of the present invention, the component(s) (b) is different to component (a).
In a more preferred variant of the second aspect, the present invention relates to a cosmetic or pharmaceutical composition or homecare product, comprising or consisting of:
The term “comprising” means that the named components are essential, but other components may be added and is still embraced by the present invention.
The term “consisting of” as used according to the present invention means that the total amount of components (a) to (c) adds up to 100% by weight, based on the total weight of the cosmetic or pharmaceutical composition or homecare product, and signifies that the subject matter is closed-ended and can only include the limitations that are expressly recited.
Whenever reference is made to “comprising” it is intended to cover both meanings as alternatives, that is the meaning can be either “comprising” or “consisting of”, unless the context dictates otherwise.
The term “at least one ...” means that the cosmetic or pharmaceutical composition or homecare product according to the present invention can comprise either one or a mixture of two, three, four, five, six or even more different of the respective components following said term.
The term “optionally” means that the subsequently described compound may but need not to be present in the composition, and that the description includes variants, in which the compound is included or variants, in which the compound is absent.
The component (a) in the cosmetic or pharmaceutical composition according to the first aspect of the present invention is either 1,2-heptanediol or 2,3-heptanediol, or a mixture of both heptanediols.
Alkanediols are glycols, i.e. any of a class or organic ompounds belonging to the alcohol family; in the molecule of a glycol, two hydroxyl (—OH) groups are attached to different carbon atoms or a carbon chain.
The component (a) in the cosmetic or pharmaceutical composition or in the homecare product according to the first aspect of the present invention is either 1,2-heptanediol (a1) or 2,3-heptanediol (a2), or a mixture comprising both heptanediols, i.e. 1,2-heptanediol plus 2,3-heptanediol (a3).
1,2-heptandediol belongs to the category of alkanediols and is a straight chain alkanediol with the general formula:
It has a carbon chain with 7 carbon atoms and the two functional OH groups of the alkanediol are in alpha,beta position and chemically bonded to the C1 and C2 carbon atoms in the alkanediol chain.
2,3-heptanediol belongs to the category of alkanediols and is a straight chain alkanediol with the general formula:
It has a carbon chain with 7 carbon atoms and the two functional OH groups of the alkanediol are in beta,gamma position and chemically bonded to the C2 and C3 carbon atoms in the alkanediol chain.
Straight chain 1,2-alkanediols have been used for more than 15 years as multifunctional actives. Short chain 1,2-alkanediols are amphiphilic compounds and thus, like 1,2-pentanediol and 1,2-hexanediol, are soluble both in water and cosmetic oils. In contrast, 1,2-octanediol tends to precipitate or recrystallize in oily solutions. On the other hand, 1,2-decanediol is a solid and soluble only in cosmetic oils. Apart from moisturizing, some 1,2-alkanediols are used as viscosity modifiers.
The component (a) in the cosmetic or pharmaceutical composition according to the second aspect of the present invention is in a first alternative at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms.
Moreover, in a second alternative of this second aspect, the component (a) may include a first linear alkanediol in combination with a second linear alkanediol, preferably at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and at least one second linear alkanediol having a carbon chain of 5 to 14 carbon atoms. Therefore, the invention also entails a mixture of a first and a second alkanediol as described herein.
Since the first linear alkanediol of the invention can be selected from the same lists and types of compounds as the linear alkanediol according to the first alternative of the second aspect, in the following, reference is made to the linear alkanediol in general, which can also be the first linear alkanediol. In mixtures of first and second linear alkanediols, where these are specifically different, the specific terms “first” and “second” will be used to distinguish the two alkanediol components.
As used in this document, the phrase “at least one linear alkanediol” or “at least one first linear alkanediol” means that the composition can comprise one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or can comprise one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms or can comprise more than one linear alkanediol or can comprise more than one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms, i.e. two, three, four or more different linear alkanediols or first linear alkanediols having a carbon chain of 5 to 14 carbon atoms.
The linear alkanediol or the first linear alkanediol consist of a chain of 5 to 14 carbon atoms joined to each other by single covalent bonds with two OH functional groups attached to two different carbon atoms in the chain.
The at least one linear alkanediol or the at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms in the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention is preferably selected from the group consisting of pentanediol, hexanediol heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.
In a preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol and tridecanediol.
In a more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of alkanediols having an uneven number of carbon atoms of 5 to 13, i.e. pentanediol, heptanediol, nonanediol, undecanediol, tridecanediol and mixtures thereof.
In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is selected from the group consisting of alkanediols having an uneven number of carbon atoms of 7, 9, 11 and 13, i.e. heptanediol, nonanediol, undecanediol and tridecanediol, or is selected from the group consisting of alkanediols having an uneven number of carbon atoms of 9 and 11, i.e. nonanediol and undecanediol, or is selected from the group consisting of alkanediols having an uneven number of carbon atoms of 9 and 13, i.e. nonanediol and tridecanediol, or is selected from the group consisting of alkanediols having an uneven number of carbon atoms of 11 and 13, i.e. undecanediol and tridecanediol.
In a still more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is either pentanediol, hexanediol, heptanediol or octanediol.
In a most preferred variant, the at least one linear alkanediol or the at least first linear alkanediol is heptanediol.
In an alternative, the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention comprises a mixture comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more second linear alkanediol having a carbon chain of 5 to 14 carbon atoms which is different from the first linear alkanediol.
This means that the alkanediol mixture is a mixture comprisinig at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and one or more, i.e. two, three, four or more second linear alkanediol having a carbon chain of 5 to 14 carbon atoms. In this alternative, the first linear alkanediol can be any of the alkanediols as described herein for the linear alkanediol in general and in particular for the first alternative of the second aspect.
For example, the mixture can include one first linear alkanediol and one, two, three or more second linear alkanediols, or the mixture can include two first linear alkanediols with one, two, three or more second linear alkanediols, etc. with the proviso, that in each mixture, the first linear alkanediols and the second linear alkanediols are different from each other.
The phrase “different from each other” means that the first linear alkanediol and the second linear alkanediols in the mixture are either different with regard to the length of their carbon chain, i.e. number of the carbon atoms, and/or with regard to their constitutional isomerism or with regard to their stereoisomerism.
Likewise, the number of the carbon atoms of the first linear alkanediol and the second linear alkanediol in the mixture can also be same. For example, the first linear alkanediol and the second linear alkanediol have a carbon chain of 7 carbon atoms, but the first linear alkanediol and the second linear alkanediol are different with regard to their constitutional isomerism or with regard to their stereoisomerism.
The second linear alkanediol preferably consists of a chain of 5 to 14 carbon atoms joined to each other by single covalent bonds with two OH functional groups attached to two different carbon atoms in the chain.
The at least one second linear alkanediol having a carbon chain of 5 to 14 carbon atoms in the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol.
In a preferred variant, the at least one second linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol and tridecanediol. If both the first and the second alkanediol is for example heptanediol, then the second linear alkanediol heptanediol is a different constitutional isomer or stereoisomer from the first linear alkanediol.
In a more preferred variant, the at least one second linear alkanediol is selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol and nonanediol, most preferably heptanediol, octanediol and nonanediol.
The term “alkanediol” within the context of the present invention also includes its constitutional isomers or position isomers. Constitutional isomers are compounds that have the same molecular formula and different connectivity. Position isomers, a particular form of constitutional isomerism, are structural isomers that can be viewed as differing only on the position of a functional group on a parent structure, which in this case is the position of the two alcohol functions.
Depending on the number of the carbon atoms of the carbon chain of the alkanediol, there are various position isomers of the alkanediol: (x,x+1) constitutional isomers; (x,x+2) constitutional isomers; (x,x+3) constitutional isomers; etc. and alpha,omega constitutional isomers when the alcohol functions are at the terminal ends of the carbon chain, wherein x stands for the number of the carbon atom in the alkanediol chain, to which the OH groups of the alkanediol are chemically bonded. For example: if x is 1, the two OH groups of the alkanediol are chemically bonded to the C1 and C2 carbon atoms in the alkanediol chain; if x is 2, the two OH groups of the alkanediol are chemically bonded to the C2 and C3 carbon atoms in the alkanediol chain, etc.
In the (x,x+1) constitutional isomers, the two OH functional groups are vicinal attached to two different adjacent carbon atoms in the chain. In the (x,x+2) constitutional isomers, the two OH functional groups are attached to two different carbon atoms in the chain where the two carbon atoms are separated by one C atom. In the (x,x+3) constitutional isomers, the two OH functional groups are attached to two different carbon atoms in the chain where the two carbon atoms are separated by two C atoms. In the alpha,omega constitutional isomers, the two functional groups are attached to the first C atom and to the terminal C atom.

In a further preferred variant of the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention, the linear alkanediol having a carbon chain of 5 to 14 carbon atoms, is preferably a non-vicinal (x,x+3) diol, selected from the group consisting of a 1,4 diol, 2,5 diol, further (x,x+3) diols, and mixtures thereof, preferably an alpha,delta 1,4 constitutional isomer.

In a still preferred variant of the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention, the linear alkanediol and in particular the first linear alkanediol and/or the second linear alkanediol, is a 1,2-alkanediol, a 2,3-alkanediol, a 3,4-alkanediol, or mixtures thereof, more preferred 2,3-alkanediol.
The 1,2-alkanediols of the linear alkanediol, in particular the first linear alkanediol having a carbon chain of 5 to 14 carbon atoms and/or the second linear alkanediol having a carbon chain of 5 to 14 carbon atoms, can preferably be those as represented by the following formulae:

If both, the first and the second alkanediol have the same number of carbon atoms, such an alkanediol combination is herein also referred to as “homo alkanediol mixture” or “homo combination”. For example, the first linear alkanediol and the second linear alkanediol have a carbon chain of 7 carbon atoms, but the first linear alkanediol and the second linear alkanediol are different with regard to their constitutional isomerism or with regard to their stereoisomerism.
If the first and the second alkanediol have a different number of carbon atoms, such an alkanediol combination is herein also referred to as “hetero alkanediol mixture” or “hetero combination”. For example, the first linear alkanediol has a carbon chain of 7 carbon atoms and the second linear alkanediol has a carbon chain of 8 carbon atoms. However, beyond that, the first linear alkanediol and the second linear alkanediol can be different with regard to their constitutional isomerism or with regard to their stereoisomerism.

In a more preferred variant of the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention, the second linear alkanediol is selected from the group consisting of:
More preferred, in the cosmetic or pharmaceutical composition or the homecare product according to the second aspect of the present invention, the second linear alkanediol is selected from the group consisting of 1,2-pentanediol, 2,3-pentanediol, 3,4-pentanediol, and mixtures thereof. However, the second linear alkanediol can also preferably be selected from the group consisting of 1,2-hexanediol, 2,3-hexanediol, 3,4-hexanediol, and mixtures thereof or can also preferably be selected from the group consisting of 1,2-heptanediol, 2,3-heptanediol, 3,4-heptanediol and mixtures thereof.
Even more preferred, in the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention, the second linear alkanediol is an alpha,beta or a beta,gamma diol as either 1,2-pentanediol, 2,3-pentanediol or a mixture thereof.

A mixture comprising 1,2-pentanediol and 2,3-hexanediol or a mixture comprising 2,3-pentanediol and 1,2-hexanediol is also possible.
Most preferred, the second linear alkanediol is 1,2-pentanediol or 2,3-pentanediol or 1,2-hexanediol or 2,3-hexanediol or 1,2-heptanediol or 2,3-heptanediol or 2,3-octanediol or 2,3-octanediol or 1,2-nonanediol or 2,3-nonanediol.
In a particularly preferred variant, the cosmetic or pharmaceutical composition or homecare product according to the second aspect of the present invention which comprises a mixture or a combination comprising at least one first linear alkanediol with and or more second linear alkanediol includes any one of the following mixtures/combinations:
In said homo alkanediol mixtures the first linear alkanediol and the second linear alkanediol have the same number of carbon atoms.
Particularly favorable is a mixture including 1,2-heptanediol in combination with 2,3-heptanediol and/or 3,4-heptanediol, or a mixture including 1,2-octanediol in combination with 2,3-octanediol and/or 3,4-octanediol.
The above specified alkanediol mixtures according to the second aspect of the present invention, comprising a 1,2-alkanediol and a 2,3-alkanediol either having the same number of carbon atoms, are characterized in that they significantly improve the solubility of a lipophilic active component compared to the respective single 1,2-alkanediol or 2,3-alkanediol substances which have only a poor solubility for lipophilic active components. This effect is observed for aqueous/glycolic formulations even with a high water content as well as for emulsions. The lipophilic active component remains solubilized and does not crystallize out or does not precipitate out during storage and, thus, results in a stable cosmetic or pharmaceutical formulation or homecare product.
Said effect or action of improving the solubility of a lipophilic active component is found for the homo mixture including 1,2-pentanediol and 2,3-pentanediol. The mixture of said alkanediol mixture and a lipophilic active component results in a clear solution and the lipophilic component does not crystallize our or does not precipitate out during storage.
A solubility improving effect can also be observed for the homo mixture including 1,2-hexanediol and 2,3-hexanediol. The mixture of said alkanediol mixture and a lipophilic active component shows high clarity and the lipophilic active component does not crystallize our or does not precipitate out during storage.
The homo mixturre including 1,2-heptanediol and 2,3-heptanediol is beneficial since it has a particular solubility improving effect of a lipophilic active component. The resulting solution of said alkanediol mixture and a liphophilic active component is clear and the lipophilic active component does not crystallize out or does not precipitate out during storage.
The alkanediol mixture comprising 1,2-octanediol and 2,3-octanediol or an alkanediol mixture comprising 1,2-nonanediol and 2,3-nonanediol are particularly advantageous, since they improve solubility of a lipophilic active component. A solution of said alkanediol mixture and a lipophilic active component shows no turbidity and the lipophilic active substance does not crystallize our or does not precipitate out during storage.
Also an alkanediol mixture comprising 1,2-decanediol and 2,3-decanediol or the alkanediol mixture comprising 1,2-undecanediol and 2,3-undecanediol significantly improves solubility of lipophilic active substances. The mixtures of said alkanediol mixtures and a lipophilic active component result in clear solutions which are stable during storage, i.e. the lipophilic active component remains solubilized in the formulation.
A solubility enhancing effect is also true for an alkanediol mixture including 1,2-dodecanediol and 2,3-dodecanediol or an alkanediol mixture including 1,2-tridecanediol and 2,3-tridecanediol. The mixtures of said alkanediol mixture and a lipophilic active component result in clear, non turbid solutions with not precipitation of the lipophilic active component during storage.
The afore specified homo alkane diol mixtures including a 1,2-alkanediol and the corresponding 2,3-alkanediol display a significant solubility improvement for lipholic active substandes and are clearly superior to the individually corresponding 1,2-alkanediols or 2,3-alkanediols, having the same concentration, but which show a poorer solubility. All solutions of said 1,2-alkanediol and 2,3-alkanediol mixtures with a lipophilic active component are clear and stable and the lipophilic active substance does not precipitate out even during storage.
Additionally, with the admixture of the corresponding liquid 2,3-alkanediol, even in small amounts, to a solid 1,2-alkanediol, the solid 1,2-alkanedioles, such as 1,2-octanediol, 1,2-nonanediol etc., can be solved, resulting in a liquid alkanediol mixture. The 2,3-alkanediol serves as solvent for the solid 1,2-alkanediols. Such liquid mixtures have the benefit that firstly the availability of the solid 1,2-alkanediol in the mixture is improved and secondly the incorporation of the solid 1,2-alkanediol in semi-finished products or final products is facilitated. This effect is particularly favorably for emulsions, in which lipophilic 1,2-alkanediols having a carbon chain of 8 or more carbon atoms, when used alone, tend to migrate into the oil phase or tend to precipitate or recrystallize.
With the solution of the solid 1,2-octanediol in the liquid 2,3-octanediol or of the solid 1,2-nonanediol in the liquid 2,3-nonanediol, the availability of the 1,2-octanediol or 1,2-nonanediol can be likewise improved in the end use.
Due to its better solubility, the availability of the lipophilic active substance or component in the cosmetic or pharmaceutical composition is increased by the above alkanediol mixtures including a 1,2-alkanediol and a 2,3-alkanediol. Additionally, due to its better solubility, the lipophilic active substance can be furnished in a higher concentration in the final formulation or can be furnished in a lower concentration in the final formulation compared to a composition including a lipophilic active component with low solubility and without the additional of an alkanediol.
Due to its better solubility, a uniformly solubilized product, in which the lipophilic active component is uniformly dissolved in the product can be obtained. Thus, the concentration of the lipophilic active component is exactly the same through the whole formulation from the very first splash to the very last ml, untill the bottle is completely empty. Without the use of an alkanediol as specified herein, the distribution of the lipophilic active component would be quite haphazardly in the formulation and would vary from application to application.
In addition, the above alkanediol mixtures comprising a 1,2-alkanediol and the corresponding 2,3-alkanediol render possible the cold preparation of cosmetic or pharmaceutical formulations or homecare products, i.e. no heating during preparation is necessary.
Thus, with the afore-mentioned properties of the specified alkanediol mixtures including a 1,2-alkanediol and the respective 2,3-alkanediol the processability in formulations can be improved.
Hence, a good compromise can be achieved when the mixture is combined in such a way as to maintain the solublity improving effect, while improving processability in formulations. The above specified 1,2-alkanediol and corresponding 2,3-alkanediol combinations solve this balancing problem over the 1,2-alkanediol substances or 2,3-alkanediol substances alone. This is well achieved by combinations such as comprising 1,2-pentanediol and 2,3-pentanediol but also for 1,2-hexanediol and 2,3-hexandiol. Also combinations such as comprising 1,2-heptanediol and 2,3-heptanediol, but also 1,2-octanediol and 2,3-octanediol show this effect. The same also counts for 1,2-nonanediol in combination with 2,3-nonanediol, but also for 1,2-decanediol in combination with 2,3-decanediol.
The afore specified homo alkanediol mixtures including a 1,2-alkanediol and the corresponding 2,3-alkanediol display a remarkably synergistic activity and are clearly superior to the individually corresponding 1,2-alkanediols or 2,3-alkanediols and having the same concentration.

Particularly favorable is a mixture including 2,3-hexanediol and 2,3-heptanediol or a mixture including 2,3-hexanediol and 2,3-octanediol or a mixture 2,3-heptanediol and 2,3-octanediol.
In the hetero alkanediol mixtures described before the first linear alkanediol and the second linear alkanediol have a different number of carbon atoms.
The above specified alkanediol mixtures according to the second aspect of the present invention, comprising a 1,2-alkanediol and a 2,3-alkanediol, are characterized in that they significantly improve the solubility of a lipophilic active component compared to the respective individual 1,2-alkanediol or 2,3-alkanediol substances which have only a poor solubility for lipophililc active components. This effect is observed for aqueous/glycolic formulations even with a high water content as well as for emulsions. The lipophilic active components remain solubilized and does not crystalliz out or does not precipitate out during storage and, thus, results in a stable cosmetic or pharmaceutical formulation or homecare product.
Of the above specified alkanediol mixtures or combinations comprising at least one first linear alkanediol and one or more second linear alkanediol according to the second aspect of the present invention, particularly favorable is a hetero mixture or a combination of alkanediols according to the second aspect of the present invention comprising 1,2-hexanediol and 2,3-octanediol or a mixture or combination of alkanediols comprising 1,2-octanediol and 2,3-hexanediol or a mixture or combination of alkanediols comprising 1,2-octanediol and 2,3-heptanediol.
These specified hetero alkanediol mixtures according to the second aspect of the present invention, show a synergistically intensified action, i.e. these mixtures improve solublitly for a lipophilic active component in a cosmetic or pharmaceutical preparation or homecare product resulting in a clear, non turbid formulation compared to their corresponding single 1,2-alkanediol or 2,3-alkanediol substances, namely 1,2-hexanediol or 1,2-octanediol or 2,3-octanediol or 2,3-hexanediol or 2,3-heptanediol.
The alkanediol mixture comprising 1,2-hexanediol and 2,3-octanediol improves the solubility of a lipophilic active substance. The mixture of said alkanediol mixture and a lipophilic active substance shows high clearness and the lipophilic active component does not crystallize out or does not precipitate out even during storage.
A solubility improving effect can also be observed for the hetero mixtures including 1,2-octanediol and 2,3-hexanediol. The resulting mixture of said alkanediol mixture and a lipophilic active substance is clear without turbidity and the lipophilic active component does not crystallize out or does not precipitate out even during storage.
A solubility improving effect toward a lipophilic active substance can also be observed for the hetero alkanediol mixture comprising 1,2-octanediol and 2,3-heptanediol.
The afore-specified mixtures are distinguished in an aqueous/glycolic formulation even with a high water content as well as an emulsion.
Additionally, with the admixture of 2,3-hexanediol or 2,3-heptanediol to the solid 1,2-octanediol, the solid 1,2-octanediol can be solved, resulting in a liquid alkanediol mixture. The 2,3-hexanediol or the 2,3-heptanediol serves as solvent for the solid 1,2-octanediol. Such liquid mixtures have the benefit that firstly the availability of the 1,2-octanediol in the mixture is improved and secondly the incorporation of the 1,2-octanediol in semi-finished products or final products is facilitated. This effect is particularly favorably for emulsions, in which lipophilic 1,2-alkanediols having a carbon chain of 8 or more carbon atoms, when used alone, tend to migrate into the oil phase or tend to recrystallize or to precipitate.
Furthermore, a distinct solubility improvement can be observed for the following specified alkanediol mixtures or combinations comprising at least one first linear alkanediol and one or more second linear alkanediol according to the second aspect of the present invention, namely a mixture of alkanediols including 1,2-pentanediol and 2,3-hexanediol; or a mixture including 1,2-pentanediol and 1,2-heptanediol; or a mixture including 1,2-pentanediol and 2,3-heptanediol; or a mixture including 1,2-pentanediol and 2,3-octanediol; or a mixture including 1,2-pentanediol and 1,2-nonanediol; or a mixture including 1,2-pentanediol and 2,3-nonanediol.
The afore specified hetero alkanediol mixtures including a 1,2-alkanediol and a 2,3-alkanediol considerably improve the solubility of a lipophilic active substance resulting in a clear solution; said effect is clearly superior to the corresponding individual 1,2-alkanediols or 2,3-alkanediols.
The alkanediol mixture including 1,2-pentanediol and 2,3-hexanediol clearly improves solubility of a lipopohilic active component. The resulting solution of said alkanediol mixture and a lipophilic active component is clear and the lipophilic active component does not crystallize out or does not precipitate out during storage.
Also, the alkanediol mixture comprising 1,2-pentanediol and 1,2-heptanediol synergistically improve the solubility of a lipophilic active component. The resulting solubtion shows no turbidity, i.e. no crystallization, and is stable during storage.
A solubility improving effect can also be observed for the alkanediol mixture comprising 1,2-pentanediol and 2,3-heptanediol. The same counts for the alkanediol mixture comprising 1,2-pentanediol and 2,3-octanediol. The resulting solutions of said alkanediol mixtures and a lipophilic active component are clear without crystallization or precipitation even during storage.
Also, an alkanediol mixture comprising 1,2-pentanediol and 1,2-nonanediol or an alkanediol mixture including 1,2-pentanediol and 2,3-nonanediol is effective in improving the solubility of a lipophilic active component. The mixture result in a stable formulation, i.e. in wich the lipohilic active component remains solbulized in which undesired crystallizing-out or precipitation of the lipophilic active component does not occur even when the mixture is stored.
With the solubility improvement of the liphilic active component, the shelf life of the cosmetic or pharmaceutical preparation or homecare product comprising such an alkanediol/lipophilic active component mixture can considerably be improved.
Furthermore, a significant improvement in the solubility of a lipophilic active component can also be observed for the hetero alkanediol mixtures, namely a mixture of alkanediols including 1,2-heptanediol and 1,2-octanediol or a mixture of alkanediols including 1,2-heptanediol and 2,3-octanediol or a mixture of alkanediols including 1,2-heptanediol and 1,2-nonanediol or a mixture or a combination of alkanediols including 1,2-heptanediol and 2,3-nonanediol.
In particular, the alkanediol mixture including 1,2-heptanediol and 1,2-octanediol or an alkanediol mixture including 1,2-heptanediol and 2,3-octanediol remarkably has a solubility improving effect towards a lipophilic active component; no or less recrystallization or precipitation of the lipophilic active component can be observed, even during storage.
A good solubility of the lipohilic active compouent can also be observed for the alkanediol mixture including 1,2-heptanediol and 1,2-nonanediol as well as for the alkanediol mixture including 1,2-heptanediol and 2,3-nonanediol. Both alkanediol mixtures are effective in better solubilize a lipophilic active component, resulting in a clear, non turbid formulations in which undesired crystallizing-out or precipitation of the liqpohilic active component remains undone, even during storage.
The afore specified hetero alkanediol mixtures show a significant solubility improvement for lipholic active substandes and are clearly superior to the individually corresponding 1,2-alkanediols or 2,3-alkanediols, having the same concentration, but which show a poorer solubility. All solutions of said hetero alkanediol mixtures with a lipophilic active component are clear and stable and the lipophilic active substance does not precipitate out even during storage.
Consequently, with the improvement of the solubility of a lipophilic active substance the storage stability and, thus, shelf life of the cosmetic or pharmaceutical preparation or homecare product can be considerably prolonged.
Due to its better solubility, the availability of the lipophilic active substance or component in the cosmetic or pharmaceutical composition is increased. Additionally, due to its better solubility, the lipophilic active substance can be furnished in a higher concentration in the final formulation or can be furnished in a lower concentration in the final formulation compared to a composition including a lipophilic active component with low solubility and without the additional of an alkanediol.
Due to its better solubility, a uniformly solubilized product, were the lipophilic active component is uniformly dissolved in the product can be obtained. Thus, the concentration of the lipophilic active component is exactly the same through the whole formulation from the very first splash to the very last ml, untill the bottle is completely empty. Without the use of an alkanediol as specified herein, the distribution of the lipophilic active component would be quite haphazardly in the formulation and would vary from application to application.
In addition, the above described hetero alkanediol mixtures comprising a 2,3-alkanediol render possible the cold preparation of cosmetic or pharmaceutical formulations or homecare products, i.e. no heating during preparation is necessary. Thus, processability in formulations can be improved.
Hence, a good compromise can be achieved when the active mixture is combined in such a way as to improve solubility for a liphophilic active component, while improving processability in formulations. The above specified alkanediol combinations comprising a first linear alkanediol and a second linear alkanediol solve this balancing problem over the the respective 1,2-alkanediol substances or 2,3-alkanediol substances alone.
Consequently, with the improvement of the solublitiy of a lipophilic active substance the storage stability and shelf life of the cosmetic or pharmaceutical preparation or homecare product can be considerably improved.
In a preferred variant according to the second aspect of the present invention in the cosmetic or pharmaceutical composition or the homecare product the linear alkanediol is selected from the group consisting of 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol, 2,3-tridecanediol, and mixtures thereof.
In a more preferred variant of the cosmetic or pharmaceutical composition or the homecare product according to the second aspect of the present invention, the linear alkanediol is selected from the group consisting of 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol, 2,3-octanediol, 2,3-nonanediol, and mixtures thereof.
Surprisingly, the addition of 2,3-pentanediol, 2,3-hexanediol, 2,3-heptanediol as well as other 2,3-alkanediols such as 2,3-octanediol, 2,3-nonanediol, 2,3-decanediol, 2,3-undecanediol, 2,3-dodecanediol and 2,3-tridecanediol results in an improved solubility for a lipophilic active substance with less or even no precipitation or crystallization during storage.
With the improvement of the solubility of a lipophilc active substance using the 2,3-alakanediols as specified above, stable formulations can be obtained and the shelf life of a cosmetic or pharmaceutical preparation or homecare product can considerably be improved.
In addition, the 2,3-alkanediols as specified above have the benefit to be liquids, whereby their incorporation in semi-finished products or final products can be facilitated and their availability in said products can be increased. Additionally, in an emulsion the 2,3-alkanediols remain in the water phase and can develop their antimicrobial activity directly where contamination with microorganisms occurs and do not tend to migrate into the oil phase.
Hence, a good compromise can be achieved when the active 2,3-alkanediol/lipophilic active substance mixture is combined in such a way as to improve solubility of the lipophilic active substane, while improving processability in formulations. The above specified 2,3-alkanediols solve this balancing problem over the solid 1,2-alkanediol substances.

The compound (b) of the cosmetic or pharmaceutical composition or homecare product according to the first aspect or the second aspect of the present invention relates to a lipophilic active component, which is used in many cosmetic compositions, in particular skincare, haircare or body care, or for pharmaceutical compositions.
The term “lipophilic” or “lipophilicity” refers to the ability of a chemical compound to dissolve in fats, oils, lipids and non-polar solvents such as hexane or toluene. Such non-polar solvents are themselves lipophilic. Thus, lipophilic substances tend to dissolve in other lipophilic substances, whereas hydrophilic substances tend to dissolve in water and other hydrophilic substances. Therefore, “lipophilic” substances are defined according to the present invention in that they are not soluble in water at RTP in a concentration of more than 0.01% by weight. The water solubility of a substance is the saturation mass concentration of the substance in water at ambient temperature.
The term “active component” within the context of the present invention means a component or a substance which imparts one or more than one benefit, functions or operate via more than one mode of action, such as anti-inflammatory, anti-itching, anti-redness, anti-dandruff, anti-microbial, anti-perspirant, deodorant, hair growth strengthening, anti-dark-spot, anti-cellulite, anti-viral, anti-oxidative, anti-wrinkle, skin-whitening, skin tanning, pain-reducing, swelling reduction, skin barrier strengthening, anti-mycotic, anti-sagging, and skin soothing properties.
The lipophilic active component according to the first and second aspect of the present invention is characterized by a log Po/w value range of ≥ 0 to 25.00. Preferably, the lipophilic active component has a log Po/w value range of ≥ 0 to 20.00, more preferred a log Po/w value range of ≥ 0 to 16.00, particularly preferred a log Po/w value range of ≥ 0 to 5.00, calculated by EPISuite v4.40 (U.S. Environmental Protection Agency; calculated with KOWWIN v1.68) . The higher the log Po/w value the poorer the solubility of the lipophilic active component in an aqueous system, such as an aqueous, aqueous/alcoholic or aqueous/glycolic based solution. More preferred is a log Po/w value range for the lipophilic active component from greater or equal to 1.00 to less than or equal to 4.00.
In general, the log P value is a constant defined in the following manner: log P = log10 (partition coefficient). Partition Coefficient, P = [organic]/[aqueous], where [ ] indicates the concentration of solute in the organic and aqueous partition, in the present case in the 1-octane and water partition. A negative value for log P means the compound has a higher affinity for the aqueous phase (it is more hydrophilic). When log P = 0 the compound is equally partitioned between the lipid and aqueous phases. A positive value for log P denotes a higher concentration in the lipid phase (i.e. the compound is more lipophilic). Log P = 1 means there is a 10 : 1 partitioning in organic : aqueous phases. log P values are important to many industries and areas of research in determining how to deliver chemical substances. Log P is used in the pharmaceutical/biotech industries to understand the behaviour of drug molecules in the body. Drug candidates are often screened according to log P, among other criteria, to help guide drug selection and analogue optimization. This is because lipophilicity is a major determining factor in a compound’s absorption, distribution in the body, penetration across vital membranes and biological barriers, metabolism and excretion (ADME properties). For topical applications, the log Po/w value of a compound should be preferably ≥ 0, more preferably in a range of ≥ 0.50 to 16.00.

The cosmetic or pharmaceutical, in particular dermatological, composition or homecare product as defined herein, are preferably based on a carrier, which comprises at least one oil phase. However, preparations solely based on water or water/alcohol or water/glycol are likewise possible or even preferred.

The oil phase or oil component in the cosmetic or pharmaceutical composition or homecare product according to the present invention is preferably a plant oil and even more preferably a liquid plant oil. It can also advantageously be a mixture of two or more plant oils components, especially liquid plant oil mixtures.
Plant oils or vegetable oils are oils extracted from seeds, or less often, from other parts of fruits. Like animal fats, plant oils are mixtures of triglycerides. Soybean oil, rapeseed oil and cocoa butter are examples of plant oils from seeds. Olive oil, palm oil and rice bran oil are examples of oils from other parts of fruits. In common usage, plant oil or vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature or at 35 to 37° C. skin temperature. Vegetable oils are usually edible.
The term “plant oils” also includes unsaturated plant oils. Unsaturated oils or vegetable oils can be transformed through partial or complete “hydrogenation” into oils of higher melting point. The hydrogenation process involves “sparging” the oil at high temperature and pressure with hydrogen in the presence of a catalyst, typically a powdered nickel compound. As each carbon-carbon double-bond is chemically reduced to a single bond, two hydrogen atoms each form single bonds with the two carbon atoms. The elimination of double bonds by adding hydrogen atoms is called saturation; as the degree of saturation increases, the oil progresses toward being fully hydrogenated. An oil may be hydrogenated to increase resistance to rancidity (oxidation) or to change its physical characteristics. As the degree of saturation increases, the oil’s viscosity and melting point increase.

Hydrocarbons (mineral oils) are in general organic compounds consisting entirely of hydrogen and carbon. As defined by IUPAC nomenclature or organic chemistry, the classifications for hydrocarbons are:
Hydrocarbons can be inter alia liquids (e.g. hexane and benzene), waxes or low melting solids (e.g. paraffin wax and naphthalene). The term ‘aliphatic’ refers to non-aromatic hydrocarbons. Saturated aliphatic hydrocarbons are sometimes referred to as “paraffins”. Mineral oils and waxes are mixtures of predominantly saturated hydrocarbons consisting of straight-chain, branched and ring structures with carbon chain lengths greater than C14. Mineral oils and waxes are chemical substances prepared from naturally occurring crude petroleum oil. They mainly consist of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). Hydrocarbons have been used for many decades in skin and lip care cosmetic products due to their excellent skin tolerance as well as their high protecting and cleansing performance and broad viscosity options. In contrast to vegetable oils, mineral oils are non-allergenic since they are highly stable and not susceptible to oxidation or rancidity.
In a preferred variant, the hydrocarbon as the oil component of the cosmetic or pharmaceutical composition or homecare product of the present invention is selected from the group consisting of undecane, tridecane, mineral oil, petrolatum, squalane, isohexadecane, C7 - C8 isoparaffin, C8 - C9 isoparaffin, C9 - C11 isoparaffin, C9 - C12 isoparaffin, C9 - C13 isoparaffin, C9 - C14 isoparaffin, C9 - C16 isoparaffin, C10 - C11 isoparaffin, C10 - C12 isoparaffin, C10 - C13 isoparaffin, C11 -C12 isoparaffin, C11 - C13 isoparaffin, C11 - C14 isoparaffin, C12 - C14 isoparaffin, C12 - C15 isoparaffin, C12 - C20 isoparaffin, C13 - C14 isoparaffin, C13 - C16 isoparaffin, C14 - C16 isoparaffin, C15 - C19 isoparaffin, and C18 - C70 isoparaffin. The hydrocarbon can be used either as a single component or in mixture with one or more further different hydrocarbon(s) as specified above.
In a particular preferred variant, the oil component of the cosmetic or pharmaceutical composition or homecare product of the present invention is a hydrocarbon selected from the group consisting of hydrocarbons, petrolatum, squalane, isohexadecane, C13 - C14 isoparaffin, and mixtures of two or more of the aforesaid hydrocarbons.
A fatty alcohol (or long-chain alcohol) is usually a high-molecular-weight, straight-chain primary alcohol, but can also range from as few as 4 to 6 carbons to as many as 22 to 26, derived from natural fats and oils. The precise chain length varies with the source. Some commercially important fatty alcohols are lauryl, stearyl and oleyl alcohols. They are colourless oily liquids (for smaller carbon numbers) or waxy solids, although impure samples may appear yellow. Fatty alcohols usually have an even number of carbon atoms and a single alcohol group (—OH) attached to the terminal carbon. Some are unsaturated and some are branched. Most fatty alcohols in nature are found as waxes which are esters with fatty acids and fatty alcohols. The traditional sources of fatty alcohols have largely been various vegetable oils and these remain a large-scale feedstock. The alcohols are obtained from the triglycerides (fatty acid triesters), which form the bulk of the oil. The process involves the transesterification of the triglycerides to give methyl esters which are then hydrogenated to give the fatty alcohols. Fatty alcohols are also prepared from petrochemical sources. In the Ziegler process, ethylene is oligomerized using triethylaluminium followed by air oxidation. Alternatively, ethylene can be oligomerized to give mixtures of alkenes, which are subjected to hydroformylation, this process affording odd-numbered aldehyde, which is subsequently hydrogenated. Fatty alcohols are mainly used in the production of detergents and surfactants. They are components also of cosmetic solvents. They find use as co-emulsifiers, emollients and thickeners in cosmetics.
In a preferred variant, the fatty alcohol as the oil component of the cosmetic or pharmaceutical composition or homecare product of the present invention is selected from the group consisting of phenyl propanol, dimethyl phenylbutanol, hexyldecanol, octyldodecanol, octyldecanol, tridecylalcohol, isostearyl alcohol, phenylisohexanol, phenylpropanol, trimethylbenzenepropanol, isoamylalcohol, isostearyl alcohol, and isotridecyl alcohol. The fatty alcohol can be used either as a single component or in mixture with one or more further different fatty alcohol(s) as specified above.
A fatty acid ester is a type of ester that results from the combination of a fatty acid with an alcohol. When the alcohol component is glycerol, the fatty acid esters produced can be monoglycerides, diglycerides or triglycerides. Fatty acid esters have a conditioning effect of softening the skin to create a smoothing sensation. They are also added to cosmetics to dissolve high-polarity active ingredients and UV absorbers. Esters of straight-chain fatty acids and lower alcohols are effective for dissolving slightly soluble ingredients for oils with a light touch during application. Isostearic acids and other liquid oils with branched fatty acids and unsaturated fatty acids are commonly used as emollients. Higher fatty acid esters and esters of higher alcohols with relatively high melting points are added to skin creams to adjust the application touch.
In a preferred variant, the fatty acid ester as the oil component of the cosmetic or pharmaceutical composition or homecare product of the present invention is selected from the group consisting of C12 - C15 Alkyl Benzoate, Capric/Lauric/Myristic/Oleic Triglyceride, Caprylic/Capric Triglyceride, Caprylic/Capric/Lauric Triglyceride, Caprylic/Capric/Linoleic Triglyceride, Caprylic/Capric/Myristic/Stearic Triglyceride, Caprylic/Capric/Palmitic/Stearic Triglyceride, Caprylic/Capric/Stearic Triglyceride, Caprylic/Capric/Succinic Triglyceride, Caprylyl Caprylate, Cetearyl Ethylhexanoate, Cetearyl Isononanoate, Cetearyl Nonanoate, Coco-Caprylate, Decyl Cocoate, Decyl Oleate, Dicaprylyl Carbonate, Diethyl Succinate, Diethylhexyl 2,6-Naphthalate, Diethylhexyl Carbonate, Dibutyl Adipate, Diisopropyl Adipate, Dipropylheptyl Carbonate, Ethyl Laurate, Ethylhexyl Isononanoate, Ethylhexyl Palmitate, Ethylhexyl Stearate, Glyceryl Caprylate Caprate, Glyceryl Caprylate, Glyceryl Laurate, Glyceryl Triacetyl Hydroxystearate, Glyceryl Triacetyl Ricinoleate, Hexyl Laurate, Isoamyl acetate, Isoamyl Cocoate, Isopropyl Palmitate, Isosorbide Dicaprylate, Isopropyl Myristate, Myristyl Myristate, Oleic/Linoleic Triglyceride, Oleic/Palmitic Triglyceride, Oleic/Palmitic/Lauric/Myristic/Linoleic Triglyceride, Propanediol Caprylate, Ricinoleic/Caproic/Caprylic/ Capric Triglyceride, Oleostearine, Oleyl Erucate, Palmitic/Stearic Triglyceride, Propanediol Dicaprylate Caprate, Propylheptyl Caprylate, Stearyl Heptanoate/Stearyl Caprylate, Triheptanoin, Trihydroxystearin, Triisononanoin, Triisopalmitin, Triisostearin, Trilaurin, Trilinolein, Trilinolenin, Trimyristin, Triolein, Tripalmitin, Tripalmitolein, Tripelargonin, Triricinolein, and Tristearin.

The fatty acid ester can be used either as a single component or in mixture with one or more further different fatty acid ester(s) as specified above.
An UV filter is a compound or a mixture of compounds that block or absorb ultraviolet (UV) light. Since excessive UV radiation can cause sunburn, photoaging, and skin cancer, care products such as sunscreen usually include a classification for the specific wavelengths they filter. UV classifications include UVA (320 - 400 nm), UVB (290 - 320 nm) and UVC (200 - 280 nm). UV-absorbing compounds are used not only in sunscreen, but also in other personal care products, such as lipstick, shampoo, hair spray, body wash, toilet soap, and insect repellent. Chemical filters protect against UV radiation by absorbing, reflecting, or scattering. Reflection and scattering are accomplished by inorganic physical UV filters, such as titanium dioxide (TiO2) and zinc oxide (ZnO). Absorption, mainly of UVB, is done by organic UV filters, which are known as chemical UV filters.

Odour absorbers and/or antiperspirant active agents: The cosmetic or pharmaceutical composition according to the present invention may include one or more odour absorbers and/or antiperspirant active agents (antiperspirants). Suitable odour absorbers are substances which are able to absorb and largely retain odour-forming compounds. They lower the partial pressure of the individual components, thus also reducing their rate of diffusion. It is important that perfumes must remain unimpaired in this process. Odour absorbers are not effective against bacteria. They comprise, for example, as main constituent, a complex zinc salt of ricinoleic acid or specific, largely odour-neutral fragrances which are known to the person skilled in the art as “fixatives”, such as, for example, extracts of labdanum or styrax or certain abietic acid derivatives. The odour masking agents are fragrances or perfume oils, which, in addition to their function as odour masking agents, give the deodorants their respective fragrance note. Perfume oils which may be mentioned are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts from flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches, and resins and balsams. Also suitable are animal products, such as, for example, civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol, and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate.

Preference is, however, given to using mixtures of different fragrances which together produce a pleasing fragrance note. Essential oils of relatively low volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, oil of cloves, melissa oil, mint oil, cinnamon leaf oil, linden flower oil, juniperberry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil and lavandin oil. Preference is given to using bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzylacetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, mandarin oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, clary sage oil, β-damascone, geranium oil bourbon, cyclohexyl salicylate, Vertofix coeur, iso-E-super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romilat, irotyl and floramat alone or in mixtures.

In a most preferred variant, the 1,2-heptanediol or 2,3-heptanediol or the mixture comprising 1,2-heptanediol and 2,3-heptanediol is advantageously used in the cosmetic or pharmaceutical composition or homecare product in an amount of 0.5 to 1.0% by weight, based on the total weight of the composition or homecare product.
For the heptanediol mixture, the above amounts relate to the total content of the 1,2-heptanediol and the 2,3-heptanediol in the mixture, i.e. the amount is the sum of the content of the 1,2-heptanediol and 2,3-heptanediol in the mixture.
The at least one linear alkanediol or the mixture comprising at least one first linear alkanediol and one or more second linear alkanediol according to the second aspect of the present invention is present in the cosmetic or pharmaceutical composition or homecare product in an amount of 0.001 to 15.0% by weight, based on the total weight of the composition or homecare product. In a preferred variant, the cosmetic or pharmaceutical composition or homecare product comprises the at least one linear alkanediol or the mixture comprising at least one first linear alkanediol and one or more second linear alkanediol in an amount of 0.01 to 10.0% by weight, based on the total weight of the composition or homecare product. In a more preferred variant, the at least one linear alkanediol or the mixture comprising at least one first linear alkanediol and one or more second linear alkanediol is advantageously used in the cosmetic or pharmaceutical composition or homecare product in an amount of at 0.1 to 5.0% by weight, based on the total weight of the composition. In a still more preferred variant, the at least one linear alkanediol or the mixture comprising at least one first linear alkanediol and one or more second linear alkanediol is advantageously used in the cosmetic or pharmaceutical composition or homecare product in an amount of at 0.3 to 3.0% by weight, based on the total weight of the composition.

Even more preferred, the cosmetic or pharmaceutical composition or the homecare product comprises the 2,3-alkanediol as linear alkanediol or of the mixture comprising at least one first linear alkanediol and one or more second linear alkanediol in an amount of 0.001 to 0.5% weight, preferably in an amount of 0.005 to 0.1% by weight and most preferably in an amount of 0.01 to 0.0075% by weight, based on the total weight of the composition or homecare product.
The lipophilic active component is present in the cosmetic or pharmaceutical composition or homecare product according to the present invention, in an amount of 0.001% to 5.0 by weight, based on the total weight of the composition or homecare product. In a preferred variant, the cosmetic or pharmaceutical composition or homecare product comprises the lipophilic active component in an amount of 0.005 to 4.0% by weight, based on the total weight of the composition or homecare product. In a particular preferred variant, the lipophilic active component is advantageously used in the cosmetic or pharmaceutical composition or homecare product in an amount of at 0.01 to 3.0% by weight, based on the total weight of the composition or homecare product.
As is demonstrated in the following examples 1.1 to 1.8, the presence of 1,2-heptanediol considerably improves the solubility of the lipophilic active component as defined herein in a cosmetic or pharmaceutical composition or homecare product compared to 1,2-pentanediol and 1,2-hexanediol. Surprisingly, the aqueous/glycolic formulations containing 1,2-heptanediol showed the lowest turbidity, which indicates highest clarity. Surprisingly, the solubility of the lipophilic active component was particularly distinguished in an aqueous/glycolic formulation with a high water content. A good solubility of the lipophilic active component could also be observed for emulsions. The combination of a lipophilic active component as defined above with 1,2-heptanediol surprisingly results in a stable formulation, i.e. in which the lipophilic active component remains solubilized and in which undesired crystallizing-out or precipitation of the lipophilic active component is prevented even when stored.
The same effect is also achieved for 2,3-alkanedioles, in particular 2,3-heptanediol and 2,3-octanediol. The presence of an 2,3-alkanediol considerably improves the solubility of the lipophilic active component as defined herein in a cosmetic or pharmaceutical composition or homecare product. Surprisingly, the solubility of the lipophilic active component was even distinguished in an aqueous/glycolic formulation with a high water content. A good solubility of the lipophilic active component could also be observed for emulsions. The combination of a lipophilic active component as defined above with a 2,3-alkanediol surprisingly results in a stable formulation, i.e. in which the lipophilic active component remains solubilized and in which undesired crystallizing-out or precipitation of the lipophilic active component is prevented even when stored.
As is demonstrated in the following examples 1.9 to 1.14, the presence of a mixture of an 1,2-alkanediol and a 2,3-alkanediol considerably improves the solubility of the lipophilic active component as defined herein in a cosmetic or pharmaceutical composition or homecare product compared to the corresponding 1,2-alkanediol or 2,3-alkanediol substance. Surprisingly, the aqueous/glycolic formulations containing a mixture including 1,2-heptanediol and 2,3-heptanediol or a mixture including 1,2-octanediol and 2,3-octanediol showed the lowest turbidity, which indicates highest clarity and best solublity for the lipophilic active component. The value of turbidity unit is by far lower than the value of turbidity unit for the respective single 1,2-alkanediol or 2,3-alkanediol substances. Surprisingly, the solubility of the lipophilic active component was particularly distinguished in an aqueous/glycolic formulation with a high water content. A good solubility of the lipophilic active component can also be observed for emulsions. The combination of a lipophilic active component as defined above with an alkanediol mixture including a 1,2-alkanediol and 2,3-alkanediol surprisingly results in a stable formulation, i.e. in which the lipophilic active component remains solubilized and in which undesired crystallizing-out or precipitation of the lipophilic active component is prevented even when stored.
Due to its better solubility, the availability of the lipophilic active substance or component in the cosmetic or pharmaceutical composition is increased. Additionally, due to its better solubility, the lipophilic active substance can be furnished in a higher concentration in the final formulation or can be furnished in a lower concentration in the final formulation compared to a composition including a lipophilic active component with low solubility and without the additional of an alkanediol.
Due to its better solubility, a uniformly solubilized product, in which the lipophilic active component is uniformly dissolved in the product can be obtained. Thus, the concentration of the lipophilic active component is exactly the same through the whole formulation from the very first splash to the very last ml, untill the bottle is completely empty. Without the use of an alkanediol as specified herein, the distribution of the lipophilic active component would be quite haphazardly in the formulation and would vary from application to application.
The use of 1,2-heptanediol and/or 2,3-heptanediol or a linear alkanediol, such as a 2,3-alkanediol or a mixture comprising a first linear alkanediol and a second linear alkanediol provides a stable formulation without turbidity or recrystallization or precipitation of the lipophilic active component, which can even maintained during storage.
Without the use of an alkanediol or an alkanediol mixture as specified herein, recrystallization or precipitation ot the lipophilic active component as defined herein, would increase, so that storage of such formulations would be problematic or even impossible.
Moreover, the use of 1,2-heptanediol and/or 2,3-heptanediol or a linear alkanediol or a mixture comprising a first linear alkanediol and a second linear alkanediol allows for the use of less additional solubilizers.

The following aqueous/glycolic formulation was used to demonstrate the solubilizing properties of 1,2-pentanediol, 1,2-hexanediol, 1,2-heptanediol and 1,2-octanediol.
Production method: A premix B was prepared by mixing solvent and solubilizer with Vortex for 20 seconds. Then diol was added to the premix. The active component was added to the premix and mixed with magnetic stirrer for 30 seconds. Water was added and the resulting mixture was stirred for 5 minutes. Hydrolite 8 was added to the mixture and heated to 40° C. to solve the Caprylyl Glycol.

The images of the sample solutions D (comparative), E (containing 1,2-pentanediol), F (containing 1,2-hexanediol), G (containing 1,2-heptanediol) and H (containing 1,2-octanediol) are shown in
Additionally, the turbidity of the sample solutions D to H was determined by measuring the nephelometric turbidity units (NTU) in triple determination. Device: Turb 430 IR ex WTW.
Turbidity is described as the opaqueness of a fluid due to the presence of suspended solids and is measured in terms of nephelometric turbidity units (NTU). NTU signifies that the instrument is measuring scattered light from the sample at a 90-degree angle from the incident light.
The results of the nephelometric turbidity units (NTU) of samples D to H are shown in
Surprisingly, the sample containing 1,2-heptanediol (sample G) showed the lowest turbidity unit which indicates highest clarity in comparison to samples E (containing 1,2-pentanediol), F (containing 1,2-hexanediol) and H (containing 1,2-octanediol). Sample D without 1,2-alkanediol serves as a comparative sample.

Turbidity measurements of samples A to D were no possible due to crystallizations/sedimentation.
Instead, the amount of sedimentation was gravimetric determined. After 3 days storage at 23° C. the samples A to D were filtered and the corresponding amount of solid residue was determined by weighing.
Sample C (containing 1,2-heptanediol) showed the lowest amount fo crystallization/sedimentation of 2.7 mg and the highest transparency. Sample A (containing 1,2-pentanediol) and sample B (containing 1,2-hexanediol) showed higher amounts of crystallization/sedimentation of 61.1 mg (sample A) and 18.5 mg (sample B).
