Common Name(s): Fluorosilane-titanate crosspolymer,perfluorooctyl titanate silane,ti-f-silane hybrid
DESCRIPTION
What It Does: Makes makeup resist water and oil for long-lasting wear by creating a repellent coating on pigments.
Why It's Used: Provides superior water and oil repellency versus non-fluorinated versions through the perfluorooctyl chain; used as a pigment surface treatment in waterproof and long-wear makeup.
How It Works: Perfluorooctyl chains provide omniphobic surface energy; ti-o and si-o bonds anchor the coating covalently to pigment surfaces; isostearate groups improve oil-phase compatibility.
Typically Found In: Waterproof foundations,long-wear makeup,setting powders,waterproof mascaras

Source Notes: Synthetic; fluorinated titanate-silane hybrid; applied as pigment surface coating.
SKIN COMPATIBILITY
Irritancy Rating: 2/5 โ low-moderate
Comedogenicity Rating: 1/5 โ low
Sensitivity Concerns: Pfas-class ingredient due to perfluorooctyl chain; regulatory scrutiny in eu and us for c8 pfas; check current reach status.
Safe for Sensitive Skin: Conditional โ c8 pfas regulatory status; verify current region restrictions
SAFETY & COMPATIBILITY
Safety Profile: Moderate safety profile. c8-class pfas: under eu restriction review. cosmetic use at low surface-treatment levels. ewg score: 3โ6.
Works Well With: Mineral pigments,silicone bases,waxes
Avoid Combining With: Avoid in pfas-free or clean beauty formulations; eu restrictions on c8 pfas apply
SCIENTIFIC NOTE
Perfluorooctyl (c8) silane-titanate treatments provide the highest degree of omniphobia achievable for pigment surfaces; c8 chain length is being phased out under pfas restrictions in favor of c6 or fluorine-free alternatives.
