A silicone resin that forms a durable, water-resistant film, boosting the staying power and transfer resistance of long-wear formulas. It helps sunscreens resist sweat and water.
What does Trifluoropropyldimethyl/Trimethylsiloxysilicate do in skincare?
It is a fluorinated silicone resin used mainly as a film former and texture agent in cosmetics. In formulas it helps create a smooth, water-resistant, and long-wearing film on the skin, which is useful in sunscreens and color cosmetics. It also improves spread and gives products a silky, non-greasy feel.
Is Trifluoropropyldimethyl/Trimethylsiloxysilicate natural or synthetic?
It is a synthetic ingredient. It belongs to the silicone family and is manufactured through chemical processing rather than extracted from a plant or mineral source. Its fluorinated structure is engineered to deliver water and transfer resistance.
Is Trifluoropropyldimethyl/Trimethylsiloxysilicate vegan?
It is generally considered suitable for vegan formulas because it is a fully synthetic silicone resin made without animal-derived materials. Confirming the finished product is vegan still depends on the brand's full formula and sourcing. If this matters to you, check the brand's own labeling.
