Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A phenyl-functional silicone resin that gives makeup primers their pore-blurring, soft-focus look. Inert on skin and well tolerated; the trade-off is environmental persistence typical of silicone polymers.
Skin benefits
- Soft-focus blurring effect
- Sebum and shine control
- Smooth dry-touch finish
- Highly stable film former
Known concerns
- High-molecular-weight silicone — environmental persistence
- Limited dermal-penetration risk but accumulates in waste streams
