PERFLUOROCAPRYLYL TRIETHOXYSILYLETHYL METHICONE

INCI: PERFLUOROCAPRYLYL TRIETHOXYSILYLETHYL METHICONE | Function: Film Former, Slip Modifier | Type: Fluorosilicone

What Is PERFLUOROCAPRYLYL TRIETHOXYSILYLETHYL METHICONE?

Perfluorocaprylyl Triethoxysilylethyl Methicone 是一种氟化硅氧烷 (fluorosilicone)，结合了有机硅的柔滑肤感和全氟碳链的超低表面能特性。主要用于高端彩妆（粉底、口红）中提供极致的抗水抗油 (long-wear) 效果和丝滑触感。因其持久性极强，正面临 PFAS 监管审查。

Key Skin Benefits

+ Extreme Long-wear — 同时抗水抗油，延长彩妆持妆时间
+ Silky Slip — 氟硅组合提供独特的丝滑肤感
+ Film-forming — 形成均匀透气的保护膜

Pros

+ Excellent water and sebum resistance — ideal for long-wear makeup
+ Combines silicone smoothness with fluorocarbon durability
+ Non-tacky film — comfortable wear

Cons

− PFAS compound — environmental persistence and bioaccumulation concerns
− High cost — premium specialty ingredient
− Regulatory risk — EU PFAS restriction may ban cosmetic use
− Limited biodegradability
