Additionally, the present invention relates to the use of 1,2-nonanediol and/or 2,3-nonanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols for malodour reduction or for inhibiting malodour development or for body odour control or for masking insect alluring odours. Furthermore, the present invention relates to a cosmetic product comprising a cosmetic composition of the present invention. Finally, the present invention relates to the use of 1,2-nonanediol and/or 2,3-nonanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols for producing a cosmetic product of the present invention or a homecare product.
The origin of malodour or body odour of humans or other mammalians usually lies in the sweat glands located in the skin. There are two different types of sweat glands the eccrine sweat glands and the apocrine sweat glands. In humans the eccrine sweat glands are distributed all over the body and they produce a water-based secretion for cooling the body. The locations of the apocrine sweat glands are rather limited and in humans they are located e.g. in the armpits. The apocrine sweat glands produce a substance that is thicker than eccrine sweat and provides nutrients for bacteria on the skin. In addition, the apocrine sweat contains other compounds e.g. pheromone-like compounds.
It is known that microbes living on the human skin produce a variety of different compounds like formic acid, butyric acid, 3-hydroxy-3-methylhexanoic acid and 3-methyl-3-sulfanylhexane-1-ol from the sweat produced by the apocrine sweat glands. Several compounds produced by the microbes are responsible for an unpleasant odour e.g. butyric acid has a very intense and unpleasant odour.
In this context, important microorganisms living on the skin or scalp of humans are microorganisms from the genus Staphylococcus, Corynebactrerium, Anaerococcus, Finegoldia, Moraxella, Porphyromonas, Fusobacterium, Aspergillus, Candida, Malassezia, Escherichia, Peptoniphilus; Streptococcus, Lactobacillus; Gardnerella, Fannyhessea, Epidermophyton, Trichophyton, Fusobacterium, Cutibacterium, in particular the microorganisms Staphylococcus epidermidis; Staphylococcus hominis; Corynebacterium xerosis; Corynebacterium jeikeium; Anaerococcus octavius; Finegoldia magna; Moraxella osloensis; Moraxella atlantae; Porphyromonas gingivalis; Aspergillus brasiliensis; Candida albicans; Escherichia coli; Staphylococcus aureus; Peptoniphilus lacrimalis; Streptococcus agalactiae; Lactobacillus acidophilus; Gardnerella vaginalis; Fannyhessea vaginae (Atopobium vaginae); Epidermophyton floccosum; Trichophyton rubrum; Streptococcus mutans; Fusobacterium nucleatum. In the past, the contributions of Anaerococcus octavius and Corynebacterium jeikeium to body odour development have been underestimated. Recently, it has been discovered that the microorganisms Anaerococcus octavius and Corynebacterium jeikeium are of special relevance for the production of compounds having an unpleasant smell from human sweat.
In addition, the pheromone-like compounds like the steroids androstenone and androsterone sulfate which are directly produced by the apocrine sweat glands also are responsible for an unpleasant malodour or body odour.
The compounds produced by microbes from human or animal sweat, and the compounds directly produced by the apocrine sweat glands also lead to a malodour smell of old age.
To efficiently reduce malodour or inhibit malodour development or control body odour a compound or composition needs to reduce the formation of sweat and/or the microbial activity on the skin. Additionally, the compound or composition must cover the unpleasant smell of different compounds produced by microbes or directly produced by the sweat glands.
In this context, it is to be noted that the substances used in cosmetics and pharmaceuticals as well as in homecare products must fulfil certain requirements. The compounds must be toxicologically acceptable, readily tolerated by the skin, stable in conventional cosmetic and/or pharmaceutical formulations or homecare product formulations, inexpensive to prepare, easy to formulate and the compounds need to be active at different pH-values. Furthermore, the substance must not have an unpleasant smell. In the search for new substances which are useful in cosmetic and pharmaceutical compositions there is no predictable connection between the chemical structure and other physico-chemical parameters relevant to the field of cosmetics and pharmaceuticals, i.e. the toxicological acceptability, the skin tolerability, the stability, solubility and formulation properties and the smell of a substance. Moreover, homecare products such as laundry detergents (in powdered or liquid form), fabric conditioner, dishwashing detergents, floor and surface cleaners, glass cleaners, air freshers and the like should be able to efficiently reduce the malodour or unpleasant smell such as from human sweats or from animal sweats on home furnishings and textiles such as pillows, sofa covers etc., clothes, carpets and the like.
EP 2774481 B1 discloses an antimicrobial mixture comprising 4-hydroxyacetophenone and at least one second antimicrobial agent selected from the group consisting of 1,3-propanediol, methyl propanediol, 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, ethylhexylglycerin, hexoxy-propan-1,2-diol, heptoxy-propan-1,2-diol, octoxy-propan-1,2-diol, 3-benzyloxy-propan-1,2-diol, 3-phenyl-ethyloxy-propan-1,2-diol, 3-phenylpropyloxy-propan-1,2-diol, 3-methylbenzyloxy-propan-1,2-diol, 3-phenyl propanol, 2-phenoxyethanol. The antimicrobial mixtures have a synergistic antimicrobial effect and can be used for combating underarm and foot odour or body odour in general.
However, the homecare, cosmetic and pharmaceutical industry is permanently searching for new ingredients and compositions which can further improve the usefulness of homecare products as well as cosmetic and pharmaceutical compositions in malodour reduction or inhibiting malodour development or body odour control, respectively.
It is a problem of the present invention to provide compounds and cosmetic or pharmaceutical compositions or homecare product compositions which can be efficiently used in malodour reduction or inhibiting malodour development or body odour control or masking insect alluring odours.
In order to accomplish the above problem, the present invention provides a cosmetic or pharmaceutical composition or a homecare product composition comprising or consisting of
Furthermore, the present invention provides a cosmetic or pharmaceutical composition or a homecare product composition, comprising or consisting of
Moreover, the present invention provides for the use of 1,2-nonanediol and/or 2,3-nonanediol, or at least one linear alkanediol or a mixture of at least one first linear alkanediol with one or more second linear alkanediols as defined above for malodour reduction or for inhibiting malodour development or for body odour control or for masking insect alluring odours.
In addition, the present invention provides a cosmetic product comprising a cosmetic composition according to the present invention, wherein the product is a deodorant and/or antiperspirant, an aerosol-based deo spray, deo pump spray, deo stick, deo roll on, deo cream, deo wipes, deo crystals, pickering emulsions, hydrodisperion gels, skin balms, shampoo, shower gel, foam bath, micellar water, facial cleansing solutions, cleansing wipes, intimate spray, intimate cream, intimate wash lotion, intimate wipes, aerosol-based foot spray, foot pump spray, foot bath, foot balm, soap, liquid washing, shower and bath preparation, bath product (capsule, oil, tablet, salt, bath salt, soap, etc.), effervescent preparation, mouth wash concentrate, mouth wash ready to use, repellent, anti-insect application, in particular insect repellent lotion, spray, solution or cream, mosquito repellent, human-smell-masking application, perfume composition and tooth paste.
Finally, the present invention provides for the use of 1,2-nonanediol and/or 2,3-nonanediol, or at least one linear alkanediol or a mixture of at least one first linear alkanediol with one or more second linear alkanediols as defined above for producing a cosmetic product according to the present invention or a homecare product.
The present invention is based on the recognition that the cosmetic or pharmaceutical compositions or the homecare product composition according to the present invention comprising 1,2-nonanediol and/or 2,3-nonanediol, or at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture of at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms with one or more second linear alkanediol(s) having a carbon chain of 5 to 14 carbon atoms which is different from the first linear alkanediol, in combination with at least one cooling agent provide an excellent cooling effect, an excellent antimicrobial effect and an excellent malodour coverage effect. Therefore, the utilisation of the cosmetic or pharmaceutical compositions or the homecare product composition according to the present invention allow for a reduced production of sweat by the sweat glands due to the excellent cooling effect. Moreover, the production of compounds having an unpleasant odour from sweat by microbes on the skin is inhibited due to the excellent antimicrobial effect. Additionally, the malodour of compounds contained in sweat is efficiently reduced due to the coverage of unpleasant odours by the cosmetic or pharmaceutical composition or the corresponding homecare product composition (malodour coverage). Moreover, insect alluring odours such as the odour of 1-octen-3-ol are efficiently covered. Consequently, the homecare product compositions as well as the cosmetic or pharmaceutical compositions according to the present invention are highly efficient in malodour reduction, in inhibiting malodour development, in body odour control and in masking insect alluring odours, respectively. Finally, the cosmetic or pharmaceutical compositions and the homecare product compositions according to the present invention are toxicologically acceptable, readily tolerated by the skin, stable, inexpensive to prepare, easy to formulate, active at different pH-values and do not possess an unpleasant smell.
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.

In a more preferred variant of the second aspect, the present invention relates to a composition, comprising or consisting of:
The term “comprising” means that the named components in the composition 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 (d) adds up to 100% by weight, based on the total weight of the composition, 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 cooling agent” means that the homecare product composition or cosmetic or pharmaceutical composition according to the present invention can comprise either one cooling agent or a mixture of two, three, four, five, six or even more different cooling agents.
The term “at least one linear alkanediol” means that the homecare product composition or cosmetic or pharmaceutical composition according to the present invention can comprise either one linear alkanediol or a mixture of two, three, four, five, six or even more different linear alkanediols having a carbon chain of 5 to 14 carbon atoms.
The term “at least one first linear alkanediol” means that the homecare product composition or cosmetic or pharmaceutical composition according to the present invention can comprise either one first linear alkanediol or a mixture of two, three, four, five, six or even more different first linear alkanediols having a carbon chain of 5 to 14 carbon atoms.

The term “at least one active substance for a cosmetic or pharmaceutical composition or a homecare product composition and/or additive” means that the homecare product composition or cosmetic or pharmaceutical composition according to the present invention can comprise either active substance for a cosmetic or pharmaceutical composition or a homecare product composition and/or additive or a mixture of two, three, four, five, six or even more different active substances for a cosmetic or pharmaceutical composition or a homecare product composition and/or additives.
The term “synergistic effect” is an effect achieved when two different chemical substances or biological structures interact resulting in accumulative overall effect that is greater than the sum of individual effects of any of them. In the present invention, the synergistic effect relates to a synergistic malodour reduction efficiency.
The malodour reducing or covering effect in the context of the present invention means that the offensive or to most people unpleasant olfactory perception which is usually caused by particularly odorous substances, is perceivably reduced, covered or even inhibited. Thereby, the reduction is not merely based on masking with strong fragrance.
Antimicrobial effect in the context of the present invention means that the microorganisms' growth is reduced or even inhibited, so that the number of living microorganisms is reduced.
Alkanediols are glycols, i.e. any of a class of organic compounds belonging to the alcohol family; in the molecule of a glycol, two hydroxyl (—OH) groups are attached to different carbon atoms of a carbon chain, i.e. they are alcohols (divalent alcohols).
Component (a)
The component (a) in the composition according to the first aspect of the present invention is either 1,2-nonanediol (a1) or 2,3-nonanediol (a2), or a mixture comprising both nonanediols, i.e. 1,2-nonanediol plus 2,3-nonanediol (a3).
In a preferred embodiment of the present invention the homecare product composition or the cosmetic or pharmaceutical composition comprises the component (a) which is defined as 1,2-nonanediol and/or 2,3-nonandediol. The components (a) 1,2-nonanediol and/or 2,3-nonandediol belong to the category of alkanediols and are straight chain alkanediols with two functional OH-groups in vicinal positions (alpha,beta-position or beta,gamma-position, respectively) and nine carbon atoms (C9) according to the following general formulae (left: 1,2-nonanediol; right: 2,3-nonanediol):
Both compounds 1,2-nonanediol and 2,3-nonandiol exhibit an antimicrobial effect and a malodour coverage effect. Consequently, both compounds are highly suitable as ingredients in compositions for use in malodour reduction or inhibiting malodour development or body odour control or for repelling insects. Preferably, in a homecare product composition or a cosmetic or pharmaceutical composition comprises component (a), wherein component (a) is 1,2-nonanediol and/or 2,3-nonanediol, preferably component (a) is 1,2-nonanediol or a mixture of 1,2-nonanediol and 2,3-nonanediol, and even more preferred component (a) is 1,2-nonanediol.
In the context of the present invention the term “malodour coverage” means that the unpleasant smell of one or more substances or a composition is entirely suppressed or reduced, but the coverage is not achieved by a beneficial intrinsic odour of an added compound. Generally, an unpleasant smell of a substance or a composition is improved by adding a compound exhibiting a malodour coverage effect, however the added compound does not improve the unpleasant smell of the substance or composition due to a beneficial intrinsic odour of the added compound. The added compound is an odour neutral molecule without a beneficial intrinsic odour. Therefore, in the context of the present invention the term “malodour coverage” does not relate to fragrance compounds which only cover an unpleasant smell due to a strong beneficial intrinsic odour.
In the context of the present invention, the term “inhibiting malodour development” means that the formation of an unpleasant smell is entirely suppressed or reduced. For example, the suppression or inhibition of the formation of an unpleasant smell may be achieved by the suppression or inhibition of the production of sweat and/or by the suppression or inhibition of microbial activity.
In the context of the present invention, the term “malodour reduction” means that the formation of an unpleasant smell is entirely suppressed or inhibited and/or an already existing unpleasant smell is entirely suppressed or reduced. For example, the suppression or inhibition of the formation of an unpleasant smell may be achieved by the suppression or inhibition of the production of sweat and/or by the suppression or inhibition of microbial activity. The suppression or reduction of an already existing unpleasant smell is achieved by malodour coverage. Therefore, “malodour reduction” may be achieved by inhibiting malodour development and/or malodour coverage.
In the context of the present invention, the term “body odour control” means that the malodour reduction takes place on a human or mammalian body.
In the context of the present invention, the term “masking insect alluring odours” means that the odours which allure or attract insects such as biting insects are covered or masked via the “malodour coverage” effect of the present invention. For example, the malodour and insect alluring odour of 1-octen-3-ol is covered or masked via the excellent “malodour coverage” effect of the compositions according to the present invention.
In a preferred embodiment of the present invention the homecare product composition or the cosmetic or pharmaceutical composition according to the second aspect of the present invention comprises the component (a) which is defined in a first alternative as at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or in a second alternative as a mixture of or comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms with one or more second linear alkanediol(s) having a carbon chain of 5 to 14 carbon atoms which is different to the first linear alkanediol.
The component (a) which is defined as at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture of or comprising at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms with one or more second linear alkanediol(s) having a carbon chain of 5 to 14 carbon atoms which is different to the first linear alkanediol exhibits an antimicrobial effect and a malodour coverage effect. Consequently, the component (a) is highly suitable as ingredient in compositions for use in malodour reduction or inhibiting malodour development or body odour control or for repelling insects.
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.
In a first preferred alternative, the component (a) is at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms.
Moreover, in a second preferred alternative, the component (a) is a mixture of at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms with one or more second linear alkanediol(s) having a carbon chain of 5 to 14 carbon atoms which is different to the first linear alkanediol. Preferably, the component (a) is a mixture of one first linear alkanediol with three second linear alkanediol(s) which are different to the first linear alkanediol, more preferably the component (a) is a mixture of one first linear alkanediol with two second linear alkanediol(s) which are different to the first linear alkanediol, most preferably the component (a) is a mixture of one first linear alkanediol with one second linear alkanediol which is different to the first linear alkanediol.
In the present invention the linear alkanediol, the first linear alkanediol and the second 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 having a carbon chain of 5 to 14 carbon atoms or the at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms in the homecare product composition or the cosmetic or pharmaceutical composition according to the present invention are preferably selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, and mixtures thereof, more preferably selected from the group consisting of heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol and tridecanediol, even more preferably selected from the group consisting of heptanediol, nonanediol, undecanediol and tridecanediol, still more preferably selected from the group consisting of heptanediol, nonanediol and undecanediol, still more preferably selected from the group consisting of nonanediol and undecanediol, most preferably the at least one linear alkanediol or the at least one first linear alkanediol are a nonanediol.
Thus, in a more preferred variant, the at least one linear alkanediol or the at least one first linear alkanediol is nonanediol.
According to another even more preferred variant the at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or the at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms is selected from the group consisting of heptanediol, octanediol and nonanediol.
In an alternative, the composition 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(s) having a carbon chain of 5 to 14 carbon atoms which is/are different from the first linear alkanediol(s).
This means that the alkanediol mixture is a mixture or combination comprising 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(s) 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 alkanediol(s) and the second linear alkanediol(s) are different from each other as specified above.
The phrase “different from each other means” that the first linear alkanediol(s) and the second linear alkanediol(s) 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(s) and the second linear alkanediol(s) 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 one or more second linear alkanediol(s) having a carbon chain of 5 to 14 carbon atoms in the homecare product composition or the cosmetic or pharmaceutical composition according to the present invention is/are preferably selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol and tetradecanediol. Preferably, the at least one/one or more second linear alkanediol is/are selected from the group consisting of pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol and tridecanediol, more preferably selected from the group consisting of heptanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol and tridecanediol, even more preferably selected from the group consisting of heptanediol, nonanediol, undecanediol and tridecanediol, still more preferably selected from the group consisting of heptanediol, nonanediol and undecanediol, most preferably selected from the group consisting of nonanediol and undecanediol.
If both the first and the second linear alkanediol are an alkanediol having the same chain length, then the second linear alkanediol is a different constitutional isomer or stereoisomer from the first linear alkanediol.
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, wherein 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 preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to the present invention, the linear alkanediol having a carbon chain of 5 to 14 carbon atoms, is preferably a vicinal (x,x+1)-diol, selected from the group consisting of a 1,2-diol, 2,3-diol, 3,4-diol, 4,5-diol and further (x,x+1)-diols, and mixtures thereof, preferably an alpha,beta-1,2-constitutional isomer.

In a further preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to the present invention, the linear alkanediol having a carbon chain of 5 to 14 carbon atoms, is preferably a non-vicinal (x,x+2)-diol, selected from the group consisting of a 1,3-diol, 2,4-diol, 3,5-diol, and further (x,x+2)-diols or mixtures thereof, preferably an alpha,gamma-1,3-constitutional isomer.
In a preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to the present invention, the first linear alkanediol and/or the second linear alkanediol having a carbon chain of 5 to 14 carbon atoms is a non-vicinal (x,x+2)-diol, selected from the group consisting of a 1,3-diol, 2,4-diol, 3,5-diol, 4,6-diol and further (x,x+2)-diols or mixtures thereof, preferably an alpha,gamma-1,3-consitutional isomer.
In a further preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to 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 form the group consisting of a 1,4-diol, 2,5-diol, and further (x,x+3)-diols or mixtures thereof, preferably an alpha,delta-1,4-constitutional isomer.
In a preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to the present invention, the first linear alkanediol and/or the secondary linear alkanediol having a carbon chain of 5 to 14 carbon atoms is a non-vicinal (x,x+3)-diol, selected form the group consisting of a 1,4-diol, 2,5-diol, and further (x,x+3)-diols or mixtures thereof, preferably an alpha,delta-1,4-constitutional isomer.
In a preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to the invention, the linear alkanediol or the first linear alkanediol and/or the second linear alkanediol is preferably an alpha,omega-alkanediol, more preferably, 1,7-heptanediol or 1,9-nonanediol or 1,11-undecanediol.
According to the present invention, vicinal (x,x+1)-diols are most preferred, such as alpha,beta or beta,gamma or gamma,delta etc.
In a still preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to 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 or a 3,4-alkanediol or mixtures thereof.
In the most preferred variant of the homecare product composition or the cosmetic or pharmaceutical composition according to the present invention the at least one linear alkanediol, the at least one first linear alkanediol and/or the one or more second linear alkanediol(s) is/are a (x,x+1)-constitutional isomer, in particular a 1,2-alkanediol, a 2,3-alkanediol or a 3,4-alkanediol or mixtures thereof, preferably a 1,2-alkanediol or a 2,3-alkanediol or mixtures thereof.
In a preferred variant, the composition 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(s) having a carbon chain of 5 to 14 carbon atoms wherein the number of the carbon atoms of the first and the second alkanediol is either same or different.
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”.

The above specified homo alkanediol mixtures according to the second aspect of the present invention, comprising a 1,2-alkanediol and a 2,3-alkanediol having the same number of carbon atoms are characterized by an improved synergistical antimicrobial efficacy against a broad spectrum of microorganisms compared to their respective single alkanediol substances, allow for a synergistic malodour coverage effect, and are especially useful for malodour reduction, inhibiting malodour development and body odour control based on said synergistic malodour coverage effect which is considerably increased compared to the single alkanediol substances.
The afore-specified homo alkanediol mixtures including a 1,2-alkanediol and the corresponding 2,3-alkanediol in combination with a cooling component display a remarkably synergistic activity and are clearly superior to the individually corresponding 1,2-alkanediols or 2,3-alkanediols, respectively, and having the same concentration.
However, it was further found that mixtures of different alkanediols in different ratios, i.e. compositions comprising an 1,2-alkanediol and an 2,3-alkanediol differing in their chain lengths (hetero combination) according to the present invention, show a synergistic malodour coverage effect. Thereby, already small portions of the 2,3-compound are sufficient in order to achieve a pronounced advantageous effect and to efficiently cover unpleasant malodour.
Preferably, the composition according to the present invention comprises a mixture or combination of at least one first linear alkanediol with one or more second linear alkanediol(s) which is selected from the group consisting of:

Furthermore, a distinct malodour reducing effect can also be observed for the following specified alkanediol mixtures, 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 when used in combination with a cooling agent.

The advantage of employing a 2,3-alkandiol lies not only in the malodour reducing effect, but also in the balance of other properties such as formulability in a cosmetic or pharmaceutical formulation and other solubility factors. The combination of these advantages makes the use of these 2,3-alkanediols particularly effective. This is strikingly effective for 2,3-alkandiols with longer chain lengths such as C8 to C12, preferably C8 to C10.
In a preferred variant according to the second aspect of the present invention in the cosmetic or pharmaceutical composition or the homecare product composition 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 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. Additionally, due to its better solubility, the 2,3-alkanediols can be furnished in a higher concentration in the final formulation.
Hence, a good compromise can be achieved when the active malodour reducing mixture is combined in such a way as to maintain the malodour reducing effect, while improving an improved processability in formulations. The above specified 2,3-alkanediols solve this balancing problem over the solid 1,2-alkanediol substances.
The homecare product composition or cosmetic or pharmaceutical composition according to the present invention preferably comprises a combination or mixture of:
The boosting effect of the above described alkanediols or alkanediol mixtures has the benefit, that lower concentrations are needed, in order to efficiently reduce malodour in cosmetic or pharmaceutical compositions or homecare product compositions.

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. The ethers include, for example, benzyl ethyl ether, and the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the ionones and methyl cedryl ketone, the alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethyl alcohol and terpineol, and the hydrocarbons include mainly the terpenes and balsams. 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.
Suitable astringent antiperspirant active ingredients are primarily salts of aluminium, zirconium or of zinc. Such suitable antihydrotic active ingredients are, for example, aluminium chloride, aluminium chlorohydrate, aluminium dichlorohydrate, aluminium sesquichlorohydrate and complex compounds thereof, e.g. with 1,2-propylene glycol, aluminium hydroxyallantoinate, aluminium chloride tartrate, aluminium zirconium trichlorohydrate, aluminium zirconium tetrachlorohydrate, aluminium zirconium pentachlorohydrate and complex compounds thereof, e.g. with amino acids, such as glycine.

The present invention shall now be described in detail with reference to the following examples, which are merely illustrative of the present invention, such that the content of the present invention is not limited by or to the following examples.
As demonstrated in the following examples, compositions comprising 1,2-nonanediol and/or 2,3-nonanediol, or at least one linear alkanediol having a carbon chain of 5 to 14 carbon atoms or a mixture of at least one first linear alkanediol having a carbon chain of 5 to 14 carbon atoms with one or more second linear alkanediol(s) having a carbon chain of 5 to 14 carbon atoms which is different from the first linear alkanediol, in combination with at least one cooling agent provide an excellent cooling effect, an excellent antimicrobial effect and an excellent malodour coverage effect. Therefore, such compositions are highly suitable for the preparation of cosmetic or pharmaceutical preparations, or the homecare products based on a pronounced synergistic effect of the alkanediols as such in mixture as well as the alkanediols in combination with cooling agents, allowing for an efficient inhibition of the development of an unpleasant smell due to the excellent antimicrobial effect, the efficient coverage of unpleasant odours as well as insect alluring odours. Consequently, the homecare product compositions as well as the cosmetic or pharmaceutical compositions according to the present invention are highly efficient in malodour reduction, in inhibiting malodour development, in body odour control and in masking insect alluring odours, respectively. Finally, the cosmetic or pharmaceutical compositions and the homecare product compositions according to the present invention are toxicologically acceptable, readily tolerated by the skin, stable, inexpensive to prepare, easy to formulate, active at different pH-values and do not possess an unpleasant smell.
The homecare products according to the first and second aspect of the invention are predominantly detergent formulations, usually liquids, powders, sprays, granules or tablets, used to remove dirt, including dust, stains, bad smells and clutter on surfaces or other types of housecleaning or laundry detergent that is added for cleaning laundry or liquid soap. Typical homecare products include all-purpose cleaners, dishwashing detergents, hard floor and surface cleaners, glass cleaners, carpet cleaners, oven cleaners, laundry detergents, fabric softeners, laundry scent, scent lotions, car shampoo, rim block gel, all afore-mentioned goods also in encapsulated form, air fresheners or furniture polish.
Due to their outstanding antimicrobial efficacy and odour improving properties as described above, the composition according to the first and second aspect of the present invention is suitable for the preparation of cosmetic or pharmaceutical preparations or homecare products.
Additionally, the compositions comprising or consisting of
As used herein “consumer products” are defined as a functionally effective combination of ingredients which are consumed i.e. used up, in performing the task for which the product was intended such as cleansing, cleaning, deodorising, sanitising, softening, freshening, etc. Said products are for example, personal care products (shampoo, hair conditioner, shower gels, body was, liquid or solid soap, deodorant sprays, roll-on and stick deodorants, moist wipes such as baby wipes or moist toilet tissues, refreshing wipes etc.), laundry detergents and conditioners (liquid and powdered detergents, tumble dryer sheets, fabric softener etc.), household cleaners (surface cleaners, floor cleaner, dishwashing liquid, powder or tablets, bathroom and sanitary cleaners, fabric cleaners, carpet cleaners etc.), air care products (liquid electric powered air freshener devices, aerosol sprays, pump action sprays, fragranced candles, membrane permeation devices, Liquid wick devices, oil based gel fragrances, aqueous gels etc.).
Methods
The MIC test is a test on growth inhibition. Estimation of the Minimum Inhibitory Concentration (MIC) is executed in 96 well plates. Through the comparison of bacterial growth with positive and negative controls via optical density (OD), different concentrations of given test substances are evaluated. Bacteria are cultivated under adjusted conditions based on information of the German Collection of Microorganisms and Cell Cultures (DSMZ) and stored in 50% Glycerol prior to use. Afterwards, the following method was applied:
Adding growth medium (according to microorganism) to each well of the microplate. Adding the test-substances in different concentrations, positive controls (water controls only with medium) and negative controls (benchmarks according to organism). Adding the microorganism in a concentration of 106 CFU/ml (CFU=colony forming units). Incubation of the microplates at appropriate conditions.
According to resulting growth, substance concentrations are labelled either as inhibiting or not and the corresponding MIC is defined as the lowest concentration where a complete growth inhibition is visible. Experiments at concentration limits (highest concentration labelled as growth and lowest concentration labelled as inhibiting) are performed at least twice.

Minimum Inhibitory Concentrations (MIC) are given in ppm. “>5000” indicates that 5000 ppm was tested, and no growth inhibition found, higher values were not investigated.
As can be seen from these results, all the tested alkanediols exhibited an excellent antimicrobial effect for the tested microorganisms naturally related to the human skin. The best antimicrobial effect was achieved by 1,2-undecanediol and 2,3-undecanediol. In addition, 1,2-nonanediol and 2,3-nonanediol exhibited a remarkably strong antimicrobial effect. It was only recently discovered that the microorganism Corynebacterium jeikeium is one microorganism which is responsible for producing compounds having an unpleasant smell from human sweat. The inhibition of the microbial activity of Corynebacterium jeikeium is difficult. It has been surprisingly found, that all of the tested alkanediols exhibited an antimicrobial effect for Corynebacterium jeikeium. Especially, the tested nonanediols and undecanediols showed a remarkably strong antimicrobial effect for Corynebacterium jeikeium. Therefore, all the tested alkanediols are especially useful for malodour reduction, inhibiting malodour development and body odour control, in particular 1,2-nonanediol, 2,3-nonanediol, 1,2-undecanediol and 2,3-undecanediol.
Aspergillus niger
Corynebacterium xerosis
Staphylococcus epidermidis
Anaerococcus octavius
In addition, as can be seen from the results of Table 2, 1,2-nonanediol exhibited an excellent antimicrobial effect for further tested microorganisms naturally related to the human skin. It was only recently discovered that the anaerobic microorganism Anaerococcus octavius is one microorganism which is responsible for producing compounds having an unpleasant smell from human sweat. The inhibition of the microbial activity of Anaerococcus octavius is difficult. It has been surprisingly found, that 1,2-nonanediol exhibited an antimicrobial effect for Anaerococcus octavius. Consequently, 1,2-nonanediol is especially useful for malodour reduction, inhibiting malodour development and body odour control.
Methods
The synergistic activity of 1,2-alkanediols with cooling compounds was determined by measuring the corresponding minimum inhibitory concentrations (MIC values) according to the method described above for antimicrobial activity: Minimum Inhibitory Concentration (MIC)
In order to calculate the synergy index with MIC values, the Kull equation (I) was used as follows:
SI=(MICmix×PA)/MICA+(MICmix×PB)/MICB (I)
wherein
To verify that the tested combinations act synergistically against microorganisms of the natural microbiota of mammalian skin, a corresponding experiment was conducted with representative microbial species. The synergistic activities of mixtures of 1,2-heptanediol and Menthyl lactate as well as for 1,2-nonanediol and Menthyl lactate were determined by measuring the corresponding minimum inhibitory concentrations (MIC values) as indicated in the methods section.
For all two microorganisms, synergistic effects regarding the antimicrobial efficacy were found with SI values below 1.

As can be seen from these results, the combination of 1,2-heptanediol and/or 1,2-nonanediol with Frescolat ML is especially useful for malodour reduction, inhibiting malodour development and body odour control based on a synergistic antimicrobial effect. It is believed that generally, the combination of alkanediols according to the present invention with at least one cooling agent according to the present invention exhibits a synergistic antimicrobial effect. Therefore, the cosmetic and pharmaceutical compositions as well as the homecare product compositions according to the present invention are especially useful for malodour reduction, inhibiting malodour development and body odour control, respectively, based on a strongly pronounced synergistic antimicrobial effect.
Corynebacterium xerosis
As can be seen from these results in Table 4, the combination of 1,2-heptanediol and/or 2,3-heptanediol and 1,2-nonanediol and/or 2,3-nonanediol with the cooling agents menthol and 3-((−)-menthoxy)propane-1,2-diol is especially useful for efficient malodour reduction, inhibition of malodour development and body odour control based on a pronounced synergistic antimicrobial effect arising between the alkanediol(s) and the cooling agent.
Method
Malodour coverage was tested in an established setup with a trained panel (n=5-9). For this sensory test, a defined amount of the material was applied on a filter paper together with a defined amount of sweat malodour. For evaluation, the panelists were asked to rate the individual samples on a scale from 0 to 10 (0: odourless; 10: strongest imaginable).
The results of the malodour rating for all materials were ranked and the position of the individual materials compared over time. A synergistic effect regarding reduction of malodour was found for all mixtures of Frescolat ML and 1,2-heptanediol after 24 h and 48 h, respectively.
As can be seen from the results above the pure compounds Frescolat ML, a colourless liquid used as an active cooling agent, and 1,2-heptanediol exhibit an odour with a rate of 3.6 and 3.3 after 24 h. Consequently, corresponding mixtures of both compounds should exhibit an expected odour with a rate ranging between 3.3 and 3.6 measured after 24 h. However, actually the mixtures of both compounds in different ratios exhibit an odour with a rate between 2.4 and 3.3 after 24 h. Therefore, the mixtures of both compounds, i.e. compositions comprising an alkanediol according to the present invention and a typical cooling agent, show a synergistic malodour coverage effect after 24 h.
In addition, the results shown above indicate that the pure compounds Frescolat ML and 1,2-heptanediol exhibit an odour with a rate of 3.1 and 3.3 after 48 h. Consequently, corresponding mixtures of both compounds should exhibit an expected odour with a rate ranging between 3.1 and 3.3 measured after 48 h. However, actually the mixtures of both compounds in different ratios exhibit an odour with a rate between 2.5 and 3.1 after 48 h. Therefore, the mixtures of both compounds, i.e., the cooling agent and the 1,2-alkanediol, show a synergistic malodour coverage effect after 48 h.
These results demonstrate that the combination of 1,2-heptanediol with Frescolat ML is especially useful for malodour reduction, inhibiting malodour development and body odour control based on a synergistic malodour coverage effect. It is believed that generally, the combination of alkanediols according to the present invention with at least one cooling agent according to the present invention exhibits an advantageous synergistic malodour coverage effect. Therefore, the cosmetic and pharmaceutical compositions as well as the homecare product compositions according to the present invention are especially useful for malodour reduction, inhibiting malodour development and body odour control, respectively, based on a pronounced synergistic malodour coverage effect.
Table 6 shows a pronounced synergistic effect of the combination of 1,2-nonanediol with a cooling agent: The combination of 50% Frescolat ML with 50% 1,2-nonanediol showed an efficient improvement of odour, i.e. a pronounced malodour reduction after 6 h as well as after 24 h. Furthermore, a good malodour reduction effect was observed for a mixture of 80% Frescolat ML with 20% 1,2-nonanediol after 24 h and for a mixture of 20% Frescolat ML with 80% 1,2-nonanediol after 6 h, respectively, based on a synergism between the alkanediol and the cooling agent.
Table 7 shows the results of the malodour coverage experiments for samples being based on heptanediols (C7): The above results show that a combination of 1,2-heptanediol with 2,3-heptanediol in different ratios allows for a pronounced improvement in odour based on an efficient malodour coverage compared to the use of 1,2-heptanediol of 2,3-heptanediol alone. A combination of the isomeric heptanediols results in a synergistic efficiency with is superior to the effects of the single substances. A further combination of said isomeric mixtures with additional cooling agents results in an even more increased synergy. Thereby, already small portions of the 2,3-compound are sufficient in order to achieve a pronounced advantageous effect.
As can be seen from the results above the pure alkanediol compounds exhibit an odour with a rate of 2.8 and 3.2 after 24 h. Consequently, corresponding mixtures of both compounds should exhibit an expected odour with a rate ranging between 2.8 and 3.2 measured after 24 h. However, actually the mixtures of both compounds in different ratios exhibit an odour with a rate ranging between 3.6 and 4.2 after 24 h indicating an advantageous synergy between the isomeric octanediol compounds. Therefore, the mixtures of both isomeric forms, i.e. compositions comprising an 1,2-alkanediol and an 2,3-alkanediol according to the present invention, show a synergistic malodour coverage effect after 24 h. Thereby, already small portions of the 2,3-compound are sufficient in order to achieve a pronounced advantageous effect.
As can be seen from the results above the pure alkanediol compounds differing in their chain lengths exhibit an odour with a rate of 3.1 and 3.4 after 24 h. Consequently, corresponding mixtures of both compounds should exhibit an expected odour with a rate ranging between 3.2 and 3.4 measured after 24 h. However, actually the mixtures of both compounds in different ratios exhibit an odour with a rate ranging between 3.4 and 4.1 after 24 h indicating an advantageous synergy between the 1,2-heptanediol and the 2,3-octanediol having different chain lengths. Therefore, the mixtures of said different alkanediols in different ratios, i.e. compositions comprising an 1,2-alkanediol and an 2,3-alkanediol differing in their chain lengths (hetero combination) according to the present invention, show a synergistic malodour coverage effect after 24 h. Thereby, already small portions of the 2,3-compound are sufficient in order to achieve a pronounced advantageous effect and to efficiently cover unpleasant malodour.
Method
Testing Conditions:
The fragrance ingredients (1% w/w) in aqueous/ethanolic solution (7:3) were sprayed on paper stripes and compared with solutions containing alkanediols after 10 min and 25 min, respectively.
Tested Alkanediols:
Preparation of the Fragrance Blend (“FRA-Blend”):
The fragrance ingredients specified above (Table 11) were mixed by stirring at ambient temperature with a magnetic stirrer for 5 min at 350 rpm.
Preparation of the Fragrance-Solutions:
The FRA-Blend specified above was pre-solved in the alkanediol (mixture) according to Table 12 and ethanol added. The solution was vortexed for 15 seconds. Subsequently, water was added and the resulting solution vortexed again for further 15 seconds.
For evaluating the sensorial behaviour of alkanediols in combination with different odorous compounds, the odour compounds were blended with the alkanediol (mixture) and dissolved in a EtOH/water-solution and assessed by untrained panelists (P1, P2, P3, P4, P5) in comparison to the corresponding samples which were prepared without the addition of alkanediol(s) (placebo sample). The odour intensity was accorded a corresponding value between 1 and 5 (Ranking: 1=weak odour; 5=strong odour/high odour intensity).

A clear reduction of the fragrance intensity was observed after 10 min and 25 min, respectively, by incorporating 1,2-alkanediols, 2,3-alkanediols as well as mixtures of the corresponding 1,2-alkanediols and 2,3-alkanediols. In addition, all panelists identified a reduction of a stingy/sharp notes. Especially, Aldehyd C12 NMA has a strong stingy/sharp note, which is usually hard to suppress or to cover. Therefore, the efficient suppression or coverage of the undesired fragrance note of Aldehyd C12 NMA by incorporating 1,2-alkanediols, 2,3-alkanediols as well as mixtures of the corresponding 1,2-alkanediols and 2,3-alkanediols is remarkable. Efficient improvements were found for the use of 1,2-alkanediols or 2,3-alkanediols as such. The particularly remarkable coverage of the afore-mentioned unpleasant fragrance note was especially efficient for compositions comprising 1,2-heptanediols in combination with 2,3-heptanediol and 1,2-octanediol in combination with 2,3-octanediol. No other effect was found out of pure ethanol as fragrance vehicle, therefore the compositions achieve an excellent malodour coverage effect in different media or media compositions. As can be seen from these results the compositions according to the present invention can be efficiently used for malodour reduction and for body odour control. In particular, compositions comprising 1,2-heptanediol, 2,3-heptanediol, 1,2-octanediol and/or 2,3-octanediol provide excellent effects for malodour reduction and for body odour control.

Testing Conditions:
The ingredients (1% w/w) in an aqueous/ethanolic solution (7:3) were sprayed on paper stripes and compared with solutions containing alkanediols directly and after 5 min, respectively.
Tested Substances:
Preparation of the Fragrance-Solutions:
The 1-octen-3ol was pre-solved in the alkanediol mixtures as specified in Table 19, ethanol added and the solutions vortexed for 15 seconds. Subsequently, water was added and the resulting solutions vortexed again for further 15 seconds.
Results
The results of the evaluation are additionally shown in
A clear reduction of compound intensity was observed directly and after 5 min, respectively, by adding the alkanediol mixtures specified in Table 19. All panelists (P1, P2, P3, P4, P5, P6) identified a significant reduction of the unpleasant earthy/rotten note. Therefore, a strong impact on the spot was observed for the reduction of the malodour of 1-octen-3-ol. The excellent suppression of the malodour of 1-octen-3-ol achieved by the compositions according to the present invention demonstrates that the compositions of the present invention are useful for efficiently masking insect alluring odours and sweat odours. No other effect was found out of pure ethanol as compound vehicle, therefore, the compositions achieve an excellent malodour coverage effect and effect for masking insect alluring odours in different media or media compositions. These results demonstrate that the compositions according to the present invention can be used for pronounced malodour reduction, for body odour control and for masking insect alluring odours.
Testing Conditions:
Paper stripes were dunked in the fragrance solution (1% w/w; aqueous/ethanolic (7:3); see Example 5) and compared with solutions containing alkanediols after 10 and 30 minutes, respectively.
For evaluating the sensorial behaviour of the alkanediols in combination with different odorous compounds, the odour compounds were blended with the alkanediol (mixture) an analysed according to the method described in Example 5 in comparison to the corresponding samples which were prepared without the addition of alkanediol(s) (placebo sample).
The test conditions as well as the FRA-Blend correspond to those used in Example 5 (Tables 10 and 11).
Preparation of the Fragrance-Solutions:
The FRA-Blend specified above (according to Table 11) was pre-solved in the alkanediol (mixture) according to Table 22 and ethanol added. The solution was stirred for 3 min with a magnetic stirrer. Subsequently, water was added, and the resulting solution stirred again for further 3 min.
For evaluating the sensorial behaviour of alkanediols in combination with different odorous compounds, the odour compounds were blended with the alkanediol (mixture) and dissolved in a EtOH/water-solution and assessed by untrained panelists (P1, P2, P3, P4, P5, P6, P7) in comparison to the corresponding samples which were prepared without the addition of alkanediol(s) (placebo sample). The odour intensity was accorded a corresponding value between 1 and 5 (Ranking: 1=weak odour; 5=strong odour/high odour intensity).
The odour intensity was accorded a corresponding value between 1 and 5 (Ranking: 1=weak odour; 5=strong odour/high odour intensity).
Results
The results of the evaluation are additionally shown in
Based on the above results it can be concluded that both the alkanediols as such as well as mixtures of the 1,2-alkanediols with 2,3-alkanediols efficiently mask the fragrance blend. Thereby, 1,2-heptanediol masks the fragrance the most, followed by the mixture of the two diols differing in their chain lengths (hetero combination). 2,3-Octandiol alone shows the lowest masking effect in the present trial.
