<p>An agent for protecting human hair against damage caused by UV radiation contains a compound of formula (I) with a hydrophilic end group (Z), spacer group (W), UV chromophore (Q) with an absorption range of 285-400 nm and at least one hydrophobic side group (A), where A1, A2 = hydrophobic group ; Q = UV chromophore ; W = organic group ; Z1, Z2 = hydrophilic group ; n1, n2 = 0-4 ; p, r1 = 1-2 ; q = 0-3 ; r2 = 0-1 ; and s1 = 1-3, with the proviso that n1 and n2 are not both equal to 0. Also claimed are: (i) hair cosmetic products containing 0.25-5 wt.% (I) and at least one skin or hair compatible auxiliary agent; (ii) the use of such products containing (I) for treating the hair to protect it against UV damage; and (iii) compounds of formula (II), where R11 = H, OH, 1-15C alkyl or 1-15C alkoxy ; R12 = H or 1-15C alkoxy ; A1, A2 = 8-22C alkyl ; and Hal = halogen.</p> |
