AI Technical Summary
Cosmetic preparations containing xanthan gum often lose their scent prematurely due to absorption or adsorption of perfume components, and terpinenes like α-phellandrene are sensitive to light irradiation, leading to odor changes.
A cosmetic preparation comprising xanthan gum, α-terpinene, and/or α-terpineol, with specific weight percentages, along with additional ingredients such as ethylhexylglycerol, phenoxyethanol, and PEG-40 hydrogenated castor oil, formulated as an oil-in-water emulsion and excluding certain compounds, to maintain odor stability.
The formulation maintains odor stability by preventing scent loss and resisting changes from light irradiation, particularly when using α-terpinene and/or α-terpineol, while avoiding the use of α-phellandrene.
Abstract
Description
[0001] The present invention relates to a cosmetic preparation containing xanthan gum (INCI: Xanthan Gum) and α-terpinene (INCI: Alpha Terpinene) and / or α-terpineol.
[0002] 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.
[0003] 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.
[0004] 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.
[0005] A disadvantage of the state of the art, however, is that some cosmetic ingredients, such as xanthan gum, cause cosmetic preparations to lose their fragrance prematurely or more rapidly, or to change their fragrance. This can be caused, among other things, by the absorption or adsorption of perfume ingredients on xanthan gum. This effect occurs, among other things, with terpinenes such as α-phellandrene.
[0006] The object of the present invention was therefore to eliminate the shortcomings of the prior art and to develop a cosmetic preparation that remains odor-stable despite containing xanthan gum.
[0007] Furthermore, changes in the odor of cosmetic preparations can be caused by irradiation with light, especially UV light. Terpinenes such as α-phellandrene are also particularly sensitive to light irradiation.
[0008] The object of the present invention was therefore to develop a perfumed and odor-stable cosmetic formulation that is particularly light-stable.
[0009] Surprisingly, the tasks are solved by a cosmetic preparation containing a) Xanthan gum (INCI: Xanthan Gum) and b) α-Terpinene (INCI: Alpha Terpinene) and / or α-Terpineol.
[0010] According to the invention, it is advantageous if the preparation contains xanthan gum (INCI: Xanthan Gum) in a 0.05 to 1% by weight, based on the total weight of the preparation.
[0011] If the cosmetic preparation contains α-terpinene (INCI: Alpha Terpinene), it is advantageous according to the invention if the preparation contains α-terpinene (INCI: Alpha Terpinene) in a 0.0002 to 0.2% by weight, based on the total weight of the preparation.
[0012] If the cosmetic preparation contains α-terpineol (INCI: Alpha Terpineol), it is advantageous according to the invention if the preparation contains α-terpineol in a 0.0002 to 0.2 wt%, based on the total weight of the preparation.
[0013] Advantageous embodiments of the present invention are further characterized in that the preparation contains ethylhexylglycerin.
[0014] In such a case, it is preferred according to the invention if the preparation contains ethylhexylglycerin in a weight % of 0.01 to 0.75 based on the total weight of the preparation.
[0015] It is also advantageous according to the invention if the preparation according to the invention contains phenoxyethanol.
[0016] In such a case, it is preferred according to the invention if the preparation contains phenoxyethanol in a 0.1 to 1 wt%, based on the total weight of the preparation.
[0017] 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).
[0018] 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 0.01 to 1.5 wt%, based on the total weight of the preparation.
[0019] 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).
[0020] 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.
[0021] 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: octyl methoxycinnamate), ethylhexyl 2-cyano-3,3-diphenyl acrylate (INCI: octocrylene), parabens (in particular methyl, propyl and butyl paraben), methylisothiazolinone, chloromethylisothiazolinone, DMDM hydantoin, mineral oils, mineral waxes and silicone oils.
[0022] According to the invention, cosmetic preparations which contain one or more UV filter substances are particularly advantageous.
[0023] 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 within the meaning 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 alpha terpinene and / or alpha terpineol, the preparation according to the invention may contain other perfume-producing 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-isomethyl ionone, 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 alpha-phellandrene.
[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.
[0030] In addition, the preparations according to the invention can contain the usual cosmetic ingredients and be composed like these. Comparison test
