PERFLUOROALKYLSILYL MICA
INCI: PERFLUOROALKYLSILYL MICA | Function: Slip Modifier, Anti-caking | Type: Surface-treated Mineral
What Is PERFLUOROALKYLSILYL MICA?
Perfluoroalkylsilyl Mica 是经过氟硅烷 (fluoroalkylsilane) 表面处理的云母粉。氟处理使云母同时具有疏水 (hydrophobic) 和疏油 (oleophobic) 特性，在粉饼和粉底中提供极致的丝滑触感 (silky slip) 和持久的抗结块效果，同时具有柔焦 (soft-focus) 光学效果。
Key Skin Benefits
- + Superior Slip — 氟处理赋予极度丝滑的粉体触感
- + Long-lasting Anti-caking — 疏水疏油双重防护，粉体不易结块
- + Soft-focus Effect — 云母片状结构散射光线，模糊细纹和毛孔
Pros
- + Hydrophobic and oleophobic — resists sweat and sebum for longer wear
- + Extremely smooth, silky application feel
- + Soft-focus optical blurring for fine lines and pores
- + Longer shelf life — treated mica resists clumping in humid conditions
Cons
- − Perfluoroalkyl treatment raises PFAS environmental concerns
- − More expensive than standard dimethicone-treated micas
- − Perfluorinated surface treatments face increasing regulatory scrutiny in EU
- − Not biodegradable — mica mining also has ethical sourcing concerns
