[0003] Cosmetic preparation containing xanthan gum with benzyl acetates

[0004] The present invention relates to a cosmetic preparation containing xanthan gum (INCI: Xanthan Gum) and (2-methyl-1-phenylpropan-2-yl) acetate (INCI: Dimethyl Phenethyl Acetate) and / or benzyl acetate (INCI: Benzyl Acetate).

[0005] The desire to look beautiful and attractive is deeply rooted in human nature. Although the ideal of beauty has evolved over time, the pursuit of a flawless appearance has always been a human goal. The condition and appearance of the skin plays a significant role in achieving a beautiful and attractive appearance.

[0006] In order for the skin to fully fulfill its biological functions, it requires regular cleansing and care. Cleansing the skin removes dirt, sweat, and dead skin particles, which provide an ideal breeding ground for pathogens and parasites of all kinds. Skin care products typically serve to moisturize and replenish the skin's oils. They often contain active ingredients that regenerate the skin or protect it from the harmful effects of UV radiation.

[0007] Cosmetics usually contain a number of perfume substances that are intended to mask unpleasant odors from the ingredients in the preparation and to give the cosmetic its individual, manufacturer-typical smell.

[0008] A disadvantage of the prior art, however, is that some cosmetic ingredients such as xanthan gum cause cosmetic preparations to lose their fragrance prematurely or at an accelerated rate, or the preparation itself to change its fragrance. This can be caused, among other things, by the absorption or adsorption of perfume ingredients by xanthan gum. This effect occurs, among other things, with acetates such as cinnamyl acetate (INCI: Cinnamyl Acetate). Therefore, the object of the present invention was to eliminate the deficiencies of the prior art and to develop a cosmetic preparation that remains odor-stable despite containing xanthan gum.

[0009] Odor changes in cosmetic preparations can also be caused by thermal stress (heat). Acetates such as cinnamyl acetate are also particularly sensitive to heat.

[0010] It was therefore the object of the present invention to develop a perfumed and odor-stable cosmetic formulation that is particularly heat-stable.

[0011] Surprisingly, the tasks are solved by a cosmetic preparation containing a) xanthan gum (INCI: Xanthan Gum) and b) (2-methyl-1-phenylpropan-2-yl) acetate (INCI: Dimethyl Phenethyl Acetate) and / or benzyl acetate (INCI: Benzyl Acetate).

[0012] According to the invention, it is advantageous if the preparation contains xanthan gum (INCI: Xanthan Gum) in a concentration of 0.05 to 1 to 10% by weight, based on the total weight of the preparation.

[0013] If the cosmetic preparation contains (2-methyl-1-phenylpropan-2-yl) acetate (INCI: Dimethyl Phenethyl Acetate), it is advantageous according to the invention if the preparation contains (2-methyl-1-phenylpropan-2-yl) acetate (INCI: Dimethylbenzylcarbinyl acetate, DMBCA) in a concentration of 0.0002 to 0.2% by weight, based on the total weight of the preparation.

[0014] If the cosmetic preparation contains benzyl acetate (INCI: Benzyl Acetate), it is advantageous according to the invention if the preparation contains benzyl acetate (INCI: Benzyl Acetate) in a concentration of 0.0002 to 0.2% by weight, based on the total weight of the preparation.

[0015] Advantageous embodiments of the present invention are further characterized in that the preparation contains ethylhexylglycerin.

[0016] In such a case, it is preferred according to the invention if the preparation contains ethylhexylglycerin in a concentration of 0.01 to 0.75% by weight, based on the total weight of the preparation. It is also advantageous according to the invention if the preparation according to the invention contains phenoxyethanol.

[0017] In such a case, it is preferred according to the invention if the preparation contains phenoxyethanol in a concentration of 0.1 to 1% by weight, based on the total weight of the preparation.

[0018] It is furthermore advantageous within the meaning of the present invention if the preparation contains PEG-40 hydrogenated castor oil (INCI: PEG-40 Hydrogenated Castor Oil).

[0019] In such a case, it is preferred according to the invention if the preparation contains the preparation PEG-40 hydrogenated castor oil (INCI: PEG-40 Hydrogenated Castor Oil) in a concentration of 0.01 to 1.5% by weight, based on the total weight of the preparation.

[0020] Advantageous embodiments of the present invention are also characterized in that the preparation is in the form of an emulsion and, preferably, in the form of an oil-in-water emulsion (O / W emulsion).

[0021] If the preparation according to the invention is in the form of an O / W emulsion, it is advantageous according to the invention if the preparation contains one or more O / W emulsifiers selected from the group of the compounds glyceryl stearate citrate, glyceryl stearate (self-emulsifying), stearic acid, stearate salts, polyglyceryl-3 methylglycose distearate, sodium cetearoyl sulfate, potassium cetyl phosphate, polyglyceryl-10 stearate, sodium stearyl glutamate, polyglyceryl-3 polyricinoleate (INCI: polyglyceryl-3 polyricinoleate), polyglyceryl-3 diisostearate and polyglyceryl-4 diisostearate / polyhydroxystearate / sebacate.

[0022] It is also advantageous in the sense of the present invention if the preparation is free from polyacrylates, cross-linked acrylate / C10-C30 alkyl acrylate polymers, vinylpyrrolidone / hexadecene copolymers, 3-(4-methylbenzylidene) camphor, 2-hydroxy-4-methoxybenzophenone (INCI: oxybenzone), 4-methoxycinnamic acid 2-ethylhexyl ester (INCI octylmethoxycinnamate), ethylhexyl 2-cyano-3,3-diphenylacrylate (INCI: octocrylene), parabens (in particular methyl-, propyl- and butylparaben), methylisothiazolinone, chloromethylisothiazolinone, DMDM ​​hydantoin, mineral oils, mineral waxes and silicone oils.

[0023] Particularly advantageous according to the invention are cosmetic preparations that contain one or more UV filter substances. In such a case, the preferred embodiments of the present invention are characterized in that the preparation contains one or more UV filter substances selected from the group of compounds (2-[-4-(Diethylamino)-2-hydroxybenzoyl]benzoic acid hexyl ester (INCI: Diethylamino Hydroxybenzoyl Hexyl Benzoate) and 2-phenylbenzimidazole-5-sulfonic acid salts).

[0024] It is furthermore advantageous in the sense of the present invention if the preparation contains one or more diols selected from the group of the compounds 2-methyl-1,3-propanediol, propane-1,2-diol, butane-1,2-diol, pentane-1,2-diol, hexane-1,2-diol, octane-1,2-diol, decane-1,2-diol.

[0025] In addition to (2-methyl-1-phenylpropan-2-yl) acetate (INCI: Dimethyl Phenethyl Acetate) and / or benzyl acetate (INCI: Benzyl Acetate), the preparation according to the invention can contain further perfuming ingredients.

[0026] It is preferred according to the invention if the preparation according to the invention contains one or more compounds selected from the group consisting of hexyl salicylate, 2-isobutyl-4-hydroxy-4-methyltetrahydropyran, adipic acid diester, methylheptenone, alpha-isomethylionone, coumarin, hexyl cinnamal, limonene, linalool, diethyl succinate, hydroxyisohexyl 3-cyclohexenecarboxaldehyde, menthyl PCA, citronellyl methyl crotonate, benzyl benzoate, benzyl alcohol, benzyl cinnamate, benzyl salicylate, citronellol, eugenol, geraniol.

[0027] However, the perfume substances according to the invention cannot be chosen arbitrarily. In particular, it is advantageous according to the invention if the preparation does not contain cinnamyl acetate.

[0028] It is advantageous according to the invention if the preparation contains ethanol.

[0029] Last but not least, the compositions advantageous according to the invention are characterized in that the preparation contains 4-hydroxyacetophenone.
