Description

[0001] New cosmetic preparation with vanillin and ethylhexyloxyphenol methoxyphenyl triazine

[0002] The present invention relates to a cosmetic preparation containing 4-hydroxy-3-methoxybenzaldehyde (INCI: Vanillin), 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: Bis-Ethylhexyloxyphenol methoxyphenyl Triazine), dipropylene glycol dibenzoate (INCI: Dipropylene Glycol Dibenzoate) and benzyl benzoate (INCI: Benzyl Benzoate).

[0003] The desire to look beautiful and attractive is rooted in human nature. Even though the ideal of beauty has changed 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.

[0004] For the skin to fully perform its biological functions, it requires regular cleansing and care. Cleansing the skin removes dirt, sweat, and dead skin cells, which provide an ideal breeding ground for pathogens and parasites of all kinds. Skin care products primarily moisturize and replenish the skin's natural oils. They often contain active ingredients that regenerate the skin or protect it from the harmful effects of UV radiation.

[0005] Cosmetics usually contain a number of perfumes intended to mask unpleasant inherent odors of preparation ingredients and to give the cosmetic its individual, manufacturer-typical scent.

[0006] However, a disadvantage of the state of the art is that the perfume ingredient vanillin (4-hydroxy-3-methoxybenzaldehyde) tends to crystallize out of the cosmetic preparations in the presence of the UV light protection filter 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: Bis-Ethylhexyloxyphenol methoxyphenyl Triazine). These crystallization nuclei then in turn lead to the crystallization of other poorly soluble, lipophilic compounds, in particular the 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: Bis- Ethylhexyloxyphenol methoxyphenyl Triazine), so that not only do the sensory properties of the preparation suffer from the crystal formation, but also the UV protection (especially the UV protection) of the affected cosmetic preparation is reduced or completely lost.

[0007] To suppress crystallization phenomena of lipophilic UV sunscreens, the oil component C12-15 alkyl benzoate is commonly used, a compound that is particularly suitable for keeping 2,4-Bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1 ,3,5-triazine (INCI: Bis-Ethylhexyloxyphenol methoxyphenyl Triazine) in solution in the oil phase.

[0008] A disadvantage of the prior art, however, is that vanillin precipitates particularly quickly and thoroughly from the preparation in C12-15 alkyl benzoate. Therefore, in the combination of 4-hydroxy-3-methoxybenzaldehyde (INCI: vanillin), 2,4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine), and C12-15 alkyl benzoate (especially under the influence of light), increased crystal formation occurs, which is precisely what should be prevented.

[0009] The object of the present invention was therefore to develop a combination of substances for cosmetic sunscreens that can be perfumed with vanillin without having to forgo (or use in a significantly reduced amount) the widely used UV filter 2,4-Bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4- methoxyphenyl)-1 ,3,5-triazine (INCI: Bis- Ethylhexyloxyphenol methoxyphenyl Triazine).

[0010] The problem is surprisingly solved by a cosmetic preparation containing 4-hydroxy-3-methoxybenzaldehyde (INCI: Vanillin), 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: Bis- Ethylhexyloxyphenol methoxyphenyl Triazine), dipropylene glycol dibenzoate (INCI: Dipropylene Glycol Dibenzoate) and benzyl benzoate (INCI: Benzyl Benzoate).

[0011] According to the invention, it is advantageous if the preparation contains 4-hydroxy-3-methoxybenzaldehyde (INCI: Vanillin) in a concentration of 0.0002 to 1.5 wt%, based on the total weight of the preparation.

Advantageous embodiments of the present invention are characterized in that the preparation contains 2,4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: Bis-Ethylhexyloxyphenol methoxyphenyl Triazine) in a concentration of 0.5 to 9.5 wt%, based on the total weight of the preparation. The preferred concentration according to the invention is between 0.5 and 5.0 wt%, based on the total weight of the preparation.

[0012] According to the invention, it is advantageous if the preparation contains dipropylene glycol dibenzoate (INCI: Dipropylene Glycol Dibenzoate) in a concentration of 0.5 to 10% by weight, based on the total weight of the preparation. The preferred concentration according to the invention is between 1.0 and 5.0% by weight, based on the total weight of the preparation.

[0013] Furthermore, according to the invention, it is advantageous if the preparation contains benzyl benzoate (INCI: Benzyl Benzoate) in a concentration of 0.0001 to 0.1 wt%, based on the total weight of the preparation. The preferred concentration according to the invention is between 0.0002 and 0.02 wt%, based on the total weight of the preparation.

[0014] Advantageous embodiments of the present invention are further characterized in that the preparation contains Ci2-is-alkylbenzoate in a concentration of at most 10 wt%, based on the total weight of the preparation.

[0015] In addition to 2,4-Bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1 ,3,5-triazine (INCI: Bis- Ethylhexyloxyphenol methoxyphenyl Triazine), the preparation according to the invention may contain further UV filters.

If the preparation according to the invention contains 2,4,6-tris-[anilino-(p-carbo-2'-ethyl-1'-hexyloxy)]-1,3,5-triazine (INCI: Ethylhexyl Triazone), this substance is advantageously used according to the invention in a concentration of 0.3 to 5.0% by weight, based on the total weight of the preparation.

[0018] The preparation according to the invention contains 4-(tert-Butyl)-4'-methoxydibenzoylmethane (INCI Butyl Methoxydibenzoylmethane), this substance is advantageously used according to the invention in a concentration of 1.0 to 5.0 wt%, based on the total weight of the preparation.

[0031] comparative test

[0032] Four percent bis-ethylhexyloxyphenol methoxyphenyl triazine is dissolved in C12-15 alkyl benzoates at 80°C. Then, 0.5 percent vanillin is added at room temperature. This solution is stored at room temperature and exposed to light. After two months of storage, distinct crystals have formed in the light pattern, which are also visible to the naked eye. Four percent bis-ethylhexyloxyphenol methoxyphenyl triazine is dissolved in dipropylene glycol dibenzoates and benzyl benzoates at 80°C. Then, 0.5 percent vanillin is added at room temperature.
