硅灵一种封闭剂,无毒无害,但会对其后的保养或护肤效果会有所阻碍。下一次使用时,原先硅灵无法被彻底洗净,随著使用的次数增多,会造成毛孔被阻塞,影响皮肤健康。

目前市场上最常見的硅灵有Dimethicone与Cyclomethicone两种。
Dimethicone有不同黏度的变化,可增强产品不同的质地表现,如低黏度、分子量低于100的就常用于露式止汗剂中,防止止汗成分鋁盐阻塞住噴雾口;中黏度、分子量介于100-500的可用于许多如丝一般滑順质感的保养品及粉底中发現它的影子;分子量大的高黏度Dimethicone则具有相当好的防水性,防水性的防晒霜及隔离霜也常使用。
Cyclomethicone属于一种高挥发度的硅灵,具有极高溶解效果,因此许多油性肌肤所使用的保养品及粉底当中也都有此成分。 (以上源于豆瓣)

p.s.神奇的是易挥发的Cyclomethicone反而是黄标6,而Dimethicone是黄标4?
