已经发现包含聚硅氧烷的防晒组合物提供了改善的协同防晒指数,所述聚硅氧烷含有作为亲油的UV-B防晒剂的苯并丙二酸酯型生色团残基和亲水的苯并咪唑型UV-B防晒剂。

根据COLIPA协议法(欧洲化妆品、清洁用品和香料联合会,防晒因素测试方法,1994粘10月)测定防晒指数。
所用的太阳模拟机SU 2000的灯强度范围为5.0-5.5mW/cm2。光辐射面积是6×1cm2;剂量递升幅度25%。
使用实施例4中的化妆品基制成以下的滤光剂组合物,得到具有相同的分布特性的稳定的防晒剂洗液。自然条件下,根据COLIPA协议法,使用剂量为2mg/cm2的防晒剂涂于人体50cm2的面积测试其SPF。
作为对照,测试下列防晒组合物:
包含实施例3的聚硅氧烷和另一个已知的亲油的UV-B滤光剂(名称是2-乙基己基-对-甲氧基-肉桂酸酯(OMC),可以PARSOL MCX的商品名商购)的防晒组合物。

10wt%P3 4.7
2wt%MC-DEA 4.2
5wt%P3+1wt%MC-DEA 4.8 4.5 7%
P3:实施例3的聚硅氧烷。
PBSA:2-苯基苯并咪唑-磺酸。
OMC:2-乙基己基对甲氧基肉桂酸酯。
MC-DEA:对甲氧基肉桂酸的二乙醇胺盐。
自然条件下的SPF:5名志愿者测试值的平均值。
SPF期望值:10wt%P3(4.7)在自然条件下的SPF值加上2wt%其它滤光剂相应值在自然条件下的SPF值,再除以2,所得到的计算值。
协同作用:自然条件下的SPF值与SPF期望值(计算值)的百分偏差。
本发明的PBSA与聚硅氧烷组合使用时,SPF值会有非成比例的上升。通常,滤光剂组合物的SPF值与单个滤光剂的计算值非常接近,因此在该组合物中可看到协同作用。
