The use as UV absorbers in sunscreens of cpds. contg. at least 2 benzazolyl gps. per mol. (I) is new. Also claimed are cpds. (I) contg. 3 or 4 SO3Y gps. per mol.

Utilization of benzazols as UV-absorbers, new benzazoles and process for their preparation

Disclosed is the use of the compounds of formula wherein A is a radical of formula (1a) or (1b) R, R1 and R5 independently from each other are hydrogen; C1-C18alkyl; or C6-C12aryl; R2, R3 and R4 independently from each other are hydrogen; or a radical of formula wherein at least one of the radicals R2, R3 and R4are a radical of formula (1c); R6, R7, R8, R9 and R10 independently from each other are hydrogen; hydroxy; C1-C18alkyl; C1-C18alkoxy;C6-C12aryl; C6-C12aryloxy; C1-C18alkylthio; carboxy; -COOM; C1-C18alkylcarboxyl; aminocarbonyl; or mono- or di-C1-C18alkylamino; M is an alkali metal ion; x is 1 or 2; and y is a number from 2 to 10; for the protection of human and animal hair and skin against the damaging effect of UV radiation. The compounds of formula (1) are high effective UV absorbers for cosmetic formulations aund can - depending on their physical properties - be used in micronized or soluble form.
