Polyquaternium-10

Description

Polyquaternium-10 is a versatile cationic polymer widely used in skincare and haircare formulations. This synthetic ingredient is derived from hydroxyethyl cellulose and quaternized with epichlorohydrin trimethylamine. Its primary function is as a conditioning agent, film former, and viscosity modifier.

In skincare products, Polyquaternium-10 enhances the texture and feel of formulations, providing a smooth, silky sensation upon application. It forms a thin, protective film on the skin's surface, which helps to retain moisture and improve product spreadability. This film-forming property also contributes to the ingredient's ability to reduce static and improve the overall appearance of the skin.

Polyquaternium-10 is particularly effective in leave-on products such as lotions, serums, and moisturizers. It is compatible with a wide range of other ingredients and stable across various pH levels. The polymer's positive charge allows it to adhere well to negatively charged skin and hair surfaces, enhancing its conditioning effects.

While generally considered safe for use in cosmetics, some individuals may experience mild irritation. As with any skincare ingredient, patch testing is recommended for those with sensitive skin or known allergies.
