Cosmetic or pharmaceutical compsn. contains liposomes including at least one compound of formula (I). R1 = CN, NO2, or halogen; R2 = CF3 or halogen; -A-B- = -C(=X)-N(R3)- or -C(SR3)=N-; X = O or S; R3 = alkyl, alkenyl, alkynyl, aryl, or aralkyl (all with ≤ 12C, opt. substd. by one or more gps. R) tri(1-6C)alkylsilyl, ≤ 7C acyl, ≤ 7C acyloxy or H; R = OH, halogen, SH, CN, ≤ 7C acyl, acyloxy ≤ 7C, aryl, O-aryl, O-aralkyl, S-aryl, the S atom may be oxidised, carboxy (or its ester, amide or salt), monoalkylamino, dialkylamino, 3-6 membered heterocycle contg. one or more O, S or N; Y = O, S, or NH. In R and R3, alkyl (except for trialkylsilyl), alkenyl and alkynyl are opt. interrupted by O, N or (oxidised) S; and aryl and aralkyl have ≤ 12C and are opt. substd. by halogen, alkyl, alkenyl, alkynyl, alkoxy, alkenyloxy, alkynyloxy, or CF3. |
