NYLON-12.

Valuable CAS 25038-74-8 / BULKING, OPACIFYING, VISCOSITY CONTROLLING

Nylon-12 is a stable, hydrophobic polymer widely used in skincare and cosmetics for its ability to enhance texture, absorb excess oil, and visually soften skin imperfections. It improves the sensory experience of products and contributes to a smoother, more mattified skin finish.

Science

Mechanism of Action

This ingredient functions primarily as a bulking and opacifying agent, and a texture enhancer. It imparts an elegant, silky feel and improves product slip and spreadability, leading to a more even application and extended wear. On the skin, Nylon-12 effectively absorbs excess oil and sweat, delivering a mattifying effect and reducing shine. Its light-scattering properties help to subtly blur the appearance of fine lines, promoting a natural-looking complexion. Furthermore, it forms a lightweight, almost invisible protective layer and assists in the controlled release of other cosmetic ingredients.
