Abstract

A light-protection combination consists of tris-(2-ethylhexyl)-4,4',4"-(1,3,5-triazine-2,4,6-triyl triimino)-tris-benzoate (I) and Guerbet alcohols of formula R1-CHR2-CH2-OH (II) R1, R2 = unbranched 2-18C alkyl. Also claimed is the use of (II) as solvent, solvent aid or solubiliser for (I), especially for use in light protection agents.

Description

The present invention relates to cosmetic and dermatological light protection tions, in particular skincare cosmetic and dermatological sunscreen preparations.

The damaging effect of the ultraviolet part of solar radiation on the skin is well known. While rays with a wavelength smaller than 290 nm (the so-called UVC range), absorbed by the ozone layer in the earth's atmosphere be, cause rays in the range between 290 nm and 320 nm, the soge called UVB, erythema, simple sunburn or even more or less severe burns.

As a maximum of the erythema efficiency of sunlight becomes the narrower area indicated at 308 nm.

To protect against UVB radiation, numerous compounds are known in which It is mostly derivatives of 3-Benzylidencamphers, the 4-aminobenzoic acid, the Cinnamic acid, salicylic acid, benzophenone and 2-phenylbenzimidazole is.

Also for the range between about 320 nm and about 400 nm, the so-called UVA Area, it is important to have filter substances available as well Radiation can cause damage. So it is proven that UVA radiation to a Damage to the elastic and collagen fibers of the connective tissue leads to what the Skin ages prematurely, and that they are the cause of numerous phototoxic and pho  allergic reactions can be seen. The damaging influence of UVB radiation can be amplified by UVA radiation.

The UV radiation can also lead to photochemical reactions, in which case the photochemical reaction products interfere with the skin metabolism.

Predominantly, such photochemical reaction products are radi kalische connections, z. B. hydroxyl radicals. Also undefined radical Photopro Due to their high reactivity, unreacted substances which are formed in the skin itself controlled controlled reactions to the day. But also singlet oxygen, a Non-radical excited state of the oxygen molecule can under UV irradiation occur, as are short-lived epoxides and many others. Singlet oxygen, for example is distinguished from the normally existing triplet oxygen (radical ground state) by increased reactivity. However exist also excited, reactive (radical) triplet states of the oxygen molecule.

Furthermore, UV radiation counts as ionizing radiation. So there is a risk that also arise ionic species on UV exposure, which in turn oxidative in to be able to intervene in the biochemical processes.

An advantageous UVB filter is the 4,4 ', 4 "- (1,3,5-triazine-2,4,6-triyltriimino) -tris-benzoic acid tris (2-ethylhexyl ester), synonymous: 2, 4,6-tris [anilino (p-carbo-2'-ethyl-1'-hexyloxy)] - 1,3,5-triazine.

This UVB filter substance is sold by BASF Aktiengesellschaft under Warenbe UVINUL® T 150 is sold and is characterized by good UV absorption properties.

The main disadvantage of this UVB filter is the poor solubility in lipids. Known Solvents for this UVB filter can not exceed about 15% by weight of this filter corresponding to about 1-1.5 wt .-% dissolved, and thus active, UV filter substance.

The use of Guerbet alcohols in cosmetics is known per se. They are characterized by the structure

out. R ₁ and R _{2 are} generally unbranched alkyl radicals.

It was, however, surprising and not foreseeable for the skilled person that light-protective active ingredient combinations of 4,4 ', 4''- (1,3,5-triazine-2,4,6-triyltriimino) -tris benzoic acid tris (2- ethylhexyl ester) and Guerbet alcohols of the structure

where R ₁ and R _{2 are} unbranched alkyl radicals having 2 to 18 carbon atoms, or the use of Guerbet alcohols of the structure

where R ₁ and R _{2 are} unbranched alkyl radicals having 2 to 18 carbon atoms as solvent, solubilizer or solubilizer for 4,4 ', 4''- (1,3,5-triazine-2,4,6-triyltriimino) tris benzoic acid tris (2-ethylhexyl ester), especially for use in light stabilizers, would remedy the disadvantages of the prior art.

It is possible according to the invention the amounts of 4,4 ', 4' '- (1,3,5-triazine-2,4,6-triyl triimino) tris-benzoic acid tris (2-ethylhexyl ester) in cosmetic or dermatological Preparations over the prior art to double.

It was amazing that by adding Isofol 16 a stabilization of solutions of 4,4 ', 4 "- (1,3,5-triazine-2,4,6-triyltriimino) -tris-benzoic acid tris (2-ethylhexyl ester) be acts because the latter substance not only has poor solubility, but also easily crystallized from its solution again. Therefore, according to the invention also a method of stabilizing solutions of the 4,4 ', 4' '- (1,3,5-triazine-2,4,6-triyltrimi no) tris-benzoic acid tris (2-ethylhexyl ester), characterized in that such Lö an effective Guerbet alcohol content is added.

The total amount of 4,4 ', 4' '- (1,3,5-triazine-2,4,6-triyltriimino) -tris-benzoic acid tris (2- ethylhexyl ester) in the finished cosmetic or dermatological preparations is advantageously from the range of 0.1-10.0 wt .-%, preferably 0.5-6.0 wt .-% chosen, based on the total weight of the preparations.

Advantageously according to the invention, the Guerbet alcohol or alcohols are selected from the group in which

Particular preference is given to pigments based on TiO ₂ .

It is particularly advantageous in the context of the present invention, although not zwin when the inorganic pigments are in hydrophobic form, d. h. that she are superficially treated water-repellent. This surface treatment can consist in that the pigments according to known methods with a thin be provided hydrophobic layer.  

One such method is, for example, that the hydrophobic surface layer according to a reaction according to

n TiO ₂ + m (RO) ₃ Si-R '→ n TiO ₂ (surface)

is produced. n and m are random stoichiometric parameters meter, R and R 'are the desired organic radicals. For example, in analogy to DE OS 33 14 742 illustrated hydrophobized pigments are advantageous.
