POLYQUATERNIUM-31

Description

Polyquaternium-31 is a synthetic, quaternary ammonium polymer widely used in personal care and cosmetic formulations. This cationic ingredient belongs to the polyquaternium family, known for its versatile applications in hair and skin care products. Polyquaternium-31 functions primarily as a film-forming agent, conditioning enhancer, and static control agent.

In skincare, Polyquaternium-31 acts as a humectant, helping to attract and retain moisture in the skin. It forms a thin, protective film on the skin's surface, which can temporarily improve skin texture and provide a smooth feel. The ingredient's positive charge allows it to adhere effectively to negatively charged skin and hair surfaces, enhancing product performance.

Polyquaternium-31 is particularly valued in haircare formulations for its ability to improve combability, reduce frizz, and enhance shine without weighing down the hair. It's commonly found in leave-in conditioners, styling products, and hair treatments. The ingredient is generally well-tolerated and considered safe for use in cosmetics at concentrations typically employed in formulations. However, as with any synthetic polymer, some individuals may experience sensitivity, necessitating patch testing for those with reactive skin.
