Description

[0001] 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), as well as dibutyl adipate (INCI: Dibutyl adipate) and / or butylene glycol dicaprylate / dicaprate (INCI: Butylene Glycol Dicaprylate / Dicaprate).

[0002] 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.

[0003] 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.

[0004] Cosmetics typically contain a number of perfumes designed to mask unpleasant inherent odors of preparation ingredients and to give the cosmetic its individual, manufacturer-specific scent.

[0005] 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 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.

[0006] To suppress crystallization phenomena of lipophilic UV light filters, the oil component C is usually added. 12-15 Alkyl benzoate is 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.

[0007] However, a disadvantage of the state of the art is that in C 12-15 Alkyl benzoate precipitates vanillin from the preparation particularly quickly and thoroughly. It is therefore present 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 C 12-15 Alkyl benzoate (especially under the influence of light) leads to increased crystal formation, which should actually be prevented.

[0008] 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).

[0009] 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), as well as Dibutyl adipate (INCI: Dibutyl adipate) and / or butylene glycol dicaprylate / dicaprate (INCI: Butylene Glycol Dicaprylate / Dicaprate).

[0034] 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 dissolved mixture 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.

[0035] Three separate reactions were conducted, each containing 4% bis-ethylhexyloxyphenol methoxyphenyl triazine in dibutyl adipate, butylene glycol dicaprylate / dicaprate, and a 1:1 mixture of dibutyl adipate and butylene glycol dicaprylate / dicaprate, respectively, at 80°C. Subsequently, 0.5% vanillin was added at room temperature. These dissolved mixtures were stored at room temperature and exposed to light. Even after six months of storage, no crystals were visible in the light pattern. Examples
