It is disclosed a solution consisting of from 15 to 60% by weight of a compound of formula (I) and from 40 to 85% by weight of at least an ester of formula (II) A-(COO-B)n (II) wherein: n is the number 1 or 2; A, when n is 1, is a C6-C20 straight or branched alkyl group, phenyl, optionally substituted with one or more C1-C4 straight or branched alkyl groups, hydroxy, C1-C4 straight or branched alkoxy, or when n is 2, A is a saturated or unsaturated C2-C12 alkylene chain, optionally substituted with one or more hydroxy groups or A is a phenylene group, B is a C3-C18 straight or branched alkyl group; C5-C12 cycloalkyl optionally substituted with one or more C1-C4 straight or branched alkyl groups. Said solution is useful for the preparation of sun protecting cosmetic compositions as well as for their stabilization against photoinduced degradation. |
