POLYQUATERNIUM-16

Description

Polyquaternium-16 is a synthetic, water-soluble polymer widely used in cosmetic and personal care formulations. This cationic compound belongs to the polyquaternium family, known for its positive electrical charge and affinity for negatively charged surfaces like hair and skin.

In skincare products, Polyquaternium-16 functions primarily as a film-forming agent and conditioning polymer. It forms a thin, flexible film on the skin's surface, providing a smooth feel and helping to retain moisture. This ingredient also exhibits antimicrobial properties, potentially contributing to product preservation and skin health.

Polyquaternium-16 is particularly valued in hair care formulations for its ability to improve combability, reduce static, and enhance shine without weighing down the hair. It adheres well to damaged areas of the hair shaft, offering temporary repair benefits.

The ingredient's molecular structure allows it to work effectively in a wide pH range, making it versatile for various product types. While generally considered safe for topical use, individuals with sensitive skin should perform patch tests before regular application. Polyquaternium-16 is compatible with many other cosmetic ingredients, facilitating its incorporation into complex formulations.
