properties of the Perfluoroalkylethyl Acrylate (FA) Copolymers and Their Applictions for Cosmetics II -Preventing Effect against makeup Deterioration in Case of Applying to Foundations

摘要

We have created a "long=lasting" makeup foundation by applying two types of perfluoroalkylethyl acrylate (FA) copolymers. The two FA copolymers are a hybrid polymer which includes hydrophbic comonomers and a SR polymer which includes hydrophilic comonomers. The properties of these FA copolymers have already been discussed in our first report. In this report, FA copolymers were appleid to the surface of cosmetic powders. Makeup foundation containing these powders was tested for surfce deterioration. Test results showed that the foundation containing hybrid polymer-treated powders had a higher tolerance against makeup deterioration than the one cntaining silicone-treated powders. Moreover, the foundation containing powders treated by both hybrid and SR polymers demonstrated an even higher tolerance. These results indicated that applying both types of FA copolymer treatment at the same time prevents makeup deterioration when both sweat and sebum are present on the skin.
