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.
