ABSTRACT:
The invention relates to oxybenzylidenebornanones which correspond to the general formula: ##STR1## in which Z and Z' denote hydrogen or a radical SO.sub.3 H, at least one of the two radicals Z and Z' denoting hydrogen, R.sub.1 denotes hydrogen, an alkyl radical having 2 to 18 carbon atoms, an alkenyl radical having 3 to 18 carbon atoms, a radical --(CH.sub.2 CH.sub.2 O).sub.n H, ##STR2## --(CH.sub.2).sub.m CO.sub.2 R, in which R denotes H or an alkyl radical, --(CH.sub.2).sub.3 SO.sub.3 H or a divalent radical --(CH.sub.2).sub.m or --CH.sub.2 --CHOH--CH.sub.2, m having the values 1 to 10, n having the values 1 to 20 and p having the values 1 to 6, and R.sub.3 and R.sub.4 representing hydrogen or an optionally branched or hydroxylic alkyl radical, or forming an aminoaliphatic heterocyclic ring with the nitrogen atom, R.sub.2 denotes a hydrogen atom, an alkoxy radical or a divalent radical --O-- bonded to the radical R.sub.1 if the latter is also divalent, and q denotes 1 or 2; if q has the value 2, R.sub.1 is a divalent radical, and, if R.sub.1 denotes hydrogen, R.sub.2 also denotes hydrogen. These compounds can be used in cosmetic compositions for providing protection against actinic rays.
