摘要

Transparent sunscreen gels comprising: (a) a silicone oil, (b) a polyoxyalkylene organopolysiloxane (I), (c) water, (d) an alcohol and/or polyol and (e) at least one water- or oil-soluble ultraviolet (UV) absorber are new. The organopolysiloxane has the following structure (I): R = H or 1-4C alkyl; n = 10-200; m = 1-25; o = 1-100, provided that o is at least equal to m and less than n/3; p = 7-17; x, y = numbers such that (C2H4)x(C3H6)yR has a molecular weight of 250-2000 and the weight ratio of oxyethylene groups to oxypropylene groups is 100:0 to 20:80.
