Claims15
An isopropylparabene free topical composition comprising an inorganic UV-filter wherein the composition further comprises a polyester comprising
- (i) between 20 to 50 wt.-%, based on the total weight of the polyester, of 2-(4-C1-8 alkoxybenzylidene)malonate units and
- (ii) between 50 to 80 wt.-%, based on the total weight of the polyester, C36 dimer fatty units, and
- with the proviso that the polyester has a hydroxyl value selected in the range of 0 to 120 mg KOH/g, a number average molecular weight (Mn) selected in the range of 1000 to 8000 g/mol and a viscosity of less than 250 Pa·s (25° C.).
