The present invention relates to compositions comprising isosorbide monoesters and one or more aliphatic vicinal diols. These compositions may be, for example, cosmetic, dermatological or pharmaceutical compositions, or else compositions which, for example, may be used for producing cosmetic, dermatological or pharmaceutical compositions. Furthermore, they may also be crop protection formulations or washing and cleaning compositions. The present invention also relates to the use of compositions comprising isosorbide monoesters and one or more aliphatic vicinal diols for preserving cosmetic, dermatological or pharmaceutical compositions, crop protection formulations or washing and cleaning compositions.
In industry, preservatives or biocides are used to protect products such as, for example, cosmetic, dermatological or pharmaceutical compositions, crop protection formulations or washing and cleaning compositions against microbial attack. Numerous preservatives which can be used for this purpose are known. It is known, for example, that aliphatic vicinal diols such as ethylhexylglycerin can be used to this end.
However, many preservatives have the disadvantage that, frequently, their preparation is expensive and based on synthetic raw materials. In addition, their preserving action frequently requires improvement, with high use concentrations being required for satisfactory preservation.
Accordingly, it was an object of the present invention to provide compositions having an advantageous preservation performance or advantageous stability to microbial attack and which are furthermore distinguished by the advantage that they are based at least in part on renewable raw materials.
Surprisingly, it has now been found that this object is achieved by compositions comprising
a) one or more compounds of the formula (I)
Accordingly, the invention provides compositions comprising
a) one or more compounds of the formula (I)
The compositions according to the invention have very good preservation performance or very good stability to microbial attack, in particular against yeasts and fungi, and owing to the presence of the compounds of the formula (I) are also based on renewable raw materials. Since the compounds of the formula (I) increase the preservative effect of aliphatic vicinal diols frequently even synergistically, in particular against yeasts and fungi, the use concentration of the aliphatic vicinal diols often based on synthetic raw materials can be reduced significantly, while maintaining an excellent antimicrobial effect of the compositions according to the invention or excellent stability of the compositions according to the invention to microbial attack, in particular to yeasts and fungi.
Compared to the use of organic acids as preservatives, the compositions according to the invention also have the advantage of an activity or stability to microbial attack, in particular to yeasts and fungi, over a wider pH range. Whereas organic acids frequently only have good activity in the pH range from 3.5 to 6, the compositions according to the invention can also be employed advantageously at higher pH.
Compositions, for example cosmetic, dermatological or pharmaceutical compositions, comprising esters based on renewable raw materials are already known.

The hydroxyl value of a substance is to be understood as meaning the amount of KOH in mg equivalent to the amount of acetic acid bound during the acetylation of 1 g of substance.
Suitable determination methods for determining the hydroxyl value are, for example, DGF C-v 17 a (53), Ph. Eur. 2.5.3 Method A and DIN 53240.
In the context of the present invention, the hydroxyl values are determined analogously to DIN 53240-2. Here, the following procedure is adopted: 1 g, accurate to 0.1 mg, of the homogenized sample to be measured is weighed out. 20.00 ml of acetylation mixture (acetylation mixture: 50 ml of acetic anhydride are stirred into 1 I of pyridine) are added. The sample is dissolved completely in the acetylation mixture, if required with stirring and heating. 5 ml of catalyst solution (catalyst solution: 2 g of 4-dimethylaminopyridine are dissolved in 100 ml of pyridine) are added. The reaction vessel is closed and placed into the water bath, preheated to 55° C., for 10 minutes, with mixing. 10 ml of fully deionized water are then added to the reaction solution, the reaction vessel is closed again and the mixture is once more allowed to react in the water bath with shaking for 10 minutes. The sample is then cooled to room temperature (25° C.). 50 ml of 2-propanol and 2 drops of phenolphthalein are then added. This solution is titrated with aqueous sodium hydroxide solution (aqueous sodium hydroxide solution c=0.5 mol/l) (Va). Under identical conditions, but without any sample added, the efficacy of the acetylation mixture is determined (Vb).
From the aqueous sodium hydroxide solution consumed in the determination of the efficacy and the titration of the sample, the hydroxyl value (OHV) is calculated using the following formula:
OHV=hydroxyl value in mg KOH/g substance
Va=aqueous sodium hydroxide solution consumed in ml during the titration of the sample
Vb=aqueous sodium hydroxide solution consumed in ml during the titration of efficacy
c=molar concentration of the aqueous sodium hydroxide solution in mol/l
t=titer of the aqueous sodium hydroxide solution
M=molar mass of KOH=56.11 g/mol
E=sample weighed out in g
(Vb−Va) is the amount of aqueous sodium hydroxide solution used in ml, which is equivalent to the amount of acetic acid bound during the above-described acetylation of the sample to be measured.
Hereinbelow, the method just described for determining the hydroxyl value is referred to as “method OHV-A”.

Further suitable solvents are, for example, triacetin (glycerol triacetate) and 1-methoxy-2-propanol.
The cosmetic, dermatological or pharmaceutical compositions according to the invention may comprise one or more substances selected from colorants, e.g. dyes and/or pigments. The dyes and/or pigments present in the cosmetic, dermatological or pharmaceutical compositions according to the invention, both organic and inorganic dyes and pigments, are selected from the corresponding positive list of the Cosmetics Regulations or the EC list of cosmetic colorants.
Oil-soluble natural dyes, such as, for example, paprika extracts, β-carotene and cochineal are furthermore advantageous.
Also advantageously used are pearlescent pigments, e.g. pearl essence (guanine/hypoxanthine mixed crystals from fish scales) and mother of pearl (ground seashells), monocrystalline pearlescent pigments such as, for example, bismuth oxychloride (BiOCl), layer substrate pigments, e.g. mica/metal oxide, silver-white pearlescent pigments from TiO2, interference pigments (TiO2, variable layer thickness), color luster pigments (Fe2O3) and combination pigments (TiO2/Fe2O3, TiO2/Cr2O3, TiO2/Prussian blue, TiO2/carmine).
Effect pigments within the context of the present invention are understood as meaning pigments which by virtue of their refraction properties produce special optical effects. Effect pigments impart to the treated surface (skin, hair, mucous membrane) luster or glitter effects or can visually conceal unevenness of the skin and skin wrinkles by means of diffuse light scattering. As a particular embodiment of the effect pigments, interference pigments are preferred. Particularly suitable effect pigments are, for example, mica particles which are coated with at least one metal oxide. Besides mica, a sheet silicate, silica gel and other SiO2 modifications are also suitable as carriers. A metal oxide frequently used for coating is, for example, titanium oxide, to which, if desired, iron oxide can be admixed. By means of the size and shape (e.g. spherical, ellipsoidal, flat, even, uneven) of the pigment particles and by means of the thickness of the oxide coating, the reflection properties can be influenced. Also other metal oxides, e.g. bismuth oxychloride (BiOCl), and the oxides of, for example, titanium, in particular the TiO2 modifications anatase and rutile, aluminum, tantalum, niobium, zirconium and hafnium. Effect pigments can also be prepared using magnesium fluoride (MgF2) and calcium fluoride (fluorspar, CaF2).
The effects can be controlled both by means of the particle size and by means of the particle size distribution of the pigment ensemble. Suitable particle size distributions extend, for example, from 2-50 μm, 5-25 μm, 5-40 μm, 5-60 μm, 5-95 μm, 5-100 μm, 10-60 μm, 10-100 μm, 10-125 μm, 20-100 μm, 20-150 μm, and <15 μm. A wider particle size distribution, for example of 20-150 μm, produces glittering effects, whereas a narrower particle size distribution of <15 μm provides for a uniform silky appearance.
If the cosmetic, dermatological or pharmaceutical compositions according to the invention comprise one or more effect pigments, these are preferably present in the compositions according to the invention in an amount of from 0.1 to 20.0% by weight, particularly preferably in an amount of from 0.5 to 10.0% by weight and especially preferably in an amount of from 1.0 to 5.0% by weight, based on the total weight of the respective composition according to the invention.

Odorant compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allyl cyclohexyl propionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ethers, the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the ionones, alpha-isomethylionone and methyl cedryl ketone, the alcohols include anethol, citronellol, eugenol, geraniol, linalol, phenylethyl alcohol and terpineol; and the hydrocarbons include primarily the terpenes and balsams.

Accordingly, the present invention furthermore provides the use of one or more compounds of the formula (I) and one or more aliphatic vicinal diols or of premixes according to the invention for preserving cosmetic, dermatological or pharmaceutical compositions, crop protection formulations or washing or cleaning compositions. Here, the cosmetic, dermatological or pharmaceutical compositions, crop protection formulations or washing or cleaning compositions are preferably preserved against bacteria, yeasts and fungi. Particularly preferably, the cosmetic, dermatological or pharmaceutical compositions, crop protection formulations or washing or cleaning compositions are preserved against yeasts and fungi and especially preferably against fungi.
The examples and applications which follow are intended to illustrate the invention in more detail, without, however, limiting it. All percentages are % by weight, unless explicitly stated otherwise.
In a stirred apparatus with distillation head, 190.0 g (1.3 mol) of isosorbide (“Sorbon” from Ecogreen Oleochemicals) and 187.5 g (1.3 mol) of octanoic acid (caprylic acid) are initially charged at 80° C. together with 0.38 g of aqueous sodium hydroxide solution (18% by weight strength, aqueous) as catalyst. With stirring and under a flow of nitrogen (10-12 liters per hour), the reaction mixture is initially heated to 180° C., where the water of reaction begins to distill off. The reaction is then heated to 190° C. over a period of 1 hour and to 210° C. over a further 2 hours. After 210° C. is reached, the esterification is continued until an acid value of <1 mg KOH/g is reached. This gives 345.7 g of amber isosorbide caprylate (97% of theory). The pH (5% by weight in ethanol/water 1:1) is 5.9. The pH was measured according to DIN EN 1262.
Further analytical characteristics of the isosorbide caprylate:
The isosorbide caprylate has the following composition:
Hereinbelow, this composition is referred to as “isosorbide caprylate 1”
Below, the antimicrobial efficacy of a composition according to the invention consisting of 50% by weight of isorbide caprylate 1 and 50% by weight of ethylhexylglycerin against bacteria, fungi and yeasts is examined (hereinbelow, the composition is referred to as “composition A”). For the tests with bacteria, composition A was diluted with butyl polyglycol and then, at 50° C., added to liquid CASO agar (casein-peptone agar) buffered to pH 7 (+/−0.2) in various concentrations (hereinbelow referred to as compositions B1, B2, etc.). For the tests with fungi and yeasts, composition A was diluted with butyl polyglycol and then added to liquid Sabouraud 4% dextrose agar buffered to pH 5.6 (+/−0.2) in various concentrations (hereinbelow referred to as compositions PH1, PH2, etc.). The compositions B1, B2, etc. and PH1, PH2 etc. were each poured into Petri dishes and each inoculated with identical amounts of bacteria, fungi and yeasts. The minimum inhibitory concentration (MIC) is the concentration at which inhibition of the growth of the bacteria, fungi and yeasts in the compositions B1, B2, etc. and PH1, PH2, etc. occurs.
The minimum inhibitory concentrations for the pure substances isosorbide caprylate 1 and ethylhexylglycerin were determined analogously.
The values determined for the minimum inhibitory concentrations “MIC mixture”, stated in Table 1 below, are based on the concentrations of composition A.
The values determined for the minimum inhibitory concentrations “QA” and “QB”, stated in Table 1 below, have already been corrected for the dilution effect of the butyl polyglycol.
From the minimum inhibitory concentrations determined, it is then possible to calculate whether a synergistic effect is present or not. Whether a synergistic effect is present is calculated according to F. C. Kull et al., Applied Microbiology 1961, 9, 538 using the formula below:
SE=Q
a
/Q
A
+Q
b
/Q
B
where
The values for Qa and Qb are determined from the values for the mixtures (“MIC mixture”) by multiplying the minimum inhibitory concentrations determined for Qa with the factor 0.5 and for Qb with the factor 0.5, because of the proportions of the ingredients—50% by weight of isosorbide caprylate 1 and 50% by weight of ethylhexylglycerin—in composition A according to the invention examined.
If an SE value>1 is obtained, an antagonistic effect is present. If SE=1, the compounds are neutral with respect to one another, and if SE<1, a synergistic effect is present.
The results of the examination of composition A are stated in Table 1 below.
Staphylococcus aureus (B)
Pseudomonas aeruginosa (B)
Escherichia coli (B)
Enterobacter aerogenes (B)
Klebsiella pneumoniae (B)
Proteus vulgaris (B)
Pseudomonas oleovorans (B)
Citrobacter freundii (B)
Candida albicans (Y)
Aspergillus brasiliensis (F)
Penicillium minioluteum (F)
Aspergillus terreus (F)
Fusarium solani (F)
Penicillium funicolosium (F)
The results listed in Table 1 show that a composition according to the invention consisting of 50% by weight of isosorbide caprylate 1 and 50% by weight of ethylhexylglycerin in particular for the yeasts and fungi tested has a synergistic effect with respect to their antimicrobial activity.
Caprylic acid is antimicrobially effective. However, since in the composition “isosorbide caprylate 1” caprylic acid is present in an amount of only 0.4% by weight, its antimicrobial efficacy in this composition is so low that it is negligible. In addition, caprylic acid has no antimicrobial activity at a pH of 6 or above.
Analogously to the determination of the antimicrobial activity according to the above example B), the antimicrobial activity of a mixture comprising, firstly, 89.6% by weight of isosorbide dicaprylate and 9.4% by weight of isosorbide monocaprylate (remainder: 1% by weight) (hereinbelow referred to as “isosorbide dicaprylate”) and, secondly, pure isosorbide was determined in further test series. The results are shown in Table 2.
Staphylococcus aureus (B)
Pseudomonas aeruginosa (B)
Escherichia coli (B)
Enterobacter aerogenes (B)
Klebsiella pneumoniae (B)
Proteus vulgaris (B)
Pseudomonas oleovorans (B)
Citrobacter freundii (B)
Candida albicans (Y)
Aspergillus brasiliensis (F)
Penicillium minioluteum (F)
Aspergillus terreus (F)
Fusarium solani (F)
Penicillium funicolosium (F)
As shown by the results of Table 2, neither isosorbide nor isosorbide dicaprylate are antimicrobially active.
From the lack of antimicrobial activity of the compounds caprylic acid, isosorbide and isosorbide dicaprylate present in the composition isosorbide caprylate 1 on the one hand and from the antimicrobial activity of the composition “isosorbide dicaprylate 1” evident from the results of table 1 on the other hand (see minimum inhibitory concentration QA for isosorbide caprylate 1 in Table 1),
it can be concluded that the compound isosorbide monocaprylate likewise present in the composition isosorbide caprylate 1 has significant antimicrobial activity.
For this reason, it is also thought that the low activity of the composition isosorbide dicaprylate with respect to the fungi Fusarium solani and Penicillium funicolosium is due to the compound isosorbide monocaprylate present therein.
