There are described liposomogenic UV absorbers, comprising a hydrophilic head group (.dbd.Z), a spacer (.dbd.W), a UV chromophore (Q) having an absorption in the range from 285 to 400 nm and at least one hydrophobic tail group (.dbd.A) of the formula (1), in which A.sub.1 and A.sub.2, independently of one another, are a hydrophobic radical, Q is a UV chromophore, W is an organic radical, Z.sub.1 and Z.sub.2, independently of one another, are a hydrophilic radical, n.sub.1 and n.sub.2, independently of one another, are a number from 0 to 4, n.sub.1 =n.sub.2 =0 not being additionally included, p is 1 or 2, q is a number from 0 to 3, r.sub.1 is 1 or 2, r.sub.2 is 0 or 1, and s.sub.1 is a number from 1 to 3. The liposomogenic UV absorbers according to the invention are preferably used as sunscreen agents in cosmetic preparations. They are capable of self-organization into bimolecular layers, and can thereby penetrate into the stratum corneum to a high extent and behave there in an extremely wash-resistant manner. ##STR1##

The use of liposomogenic UV absorbers for protecting human hair from the damaging effect of UV radiation is described. The liposomogenic UV absorbers comprise a hydrophilic head group (=Z), a spacer (=W), a UV chromophore (Q) having an absorption in the range from 285 to 400 nm and at least one hydrophobic tail group (=A). They have the formula ##STR1## in which A.sub.1 and A.sub.2 independently of one another are a hydrophobic radical;Q is a UV chromophore;W is an organic radical;Z.sub.1 and Z.sub.2 independently of one another are a hydrophilic radical; n.sub.1 and n.sub.2 independently of one another are a number from 0 to 4, where n.sub.1 =n.sub.2 = is not included;p is 1 or 2;q is a number from 0 to 3;r.sub.1 is 1 or 2;r.sub.2 is 0 or 1; ands.sub.1 is a number from 1 to 3.The liposomogenic UV absorbers are capable of self-organization into bimolecular layers, and can as a result penetrate into the stratum corneum to a high degree and are extremely resistant to washing out there.
摘要:
The present invention relates to novel s-triazine compounds, processes for their preparation and the use of these novel compounds as UV filters in sunscreen compositions. The novel compounds are those of the formula The triazine compounds of the formula (1) according to the invention are distinguished by a high UV absorption and are particularly suitable as UV filters, i.e. for protecting ultra-violet-sensitive organic materials, in particular the skin and the hair of man and animals, from the harmful action of UV radiation.
