    摘要: 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##

    摘要: 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.
