POLYQUATERNIUM-90

Description

Polyquaternium-90 is a synthetic, cationic polymer widely used in personal care and cosmetic formulations. This high-molecular-weight compound belongs to the polyquaternium family, known for its excellent conditioning and film-forming properties. Chemically, it is a quaternized copolymer of acrylamide and methacryloyloxyethyl trimethyl ammonium chloride.

In skincare and haircare products, Polyquaternium-90 functions as a conditioning agent, providing enhanced moisture retention and improved texture. Its positive charge allows it to adhere effectively to negatively charged skin and hair surfaces, creating a protective film that imparts softness and smoothness. This ingredient is particularly valued for its ability to reduce static electricity and improve combability in hair care formulations.

Polyquaternium-90 exhibits good compatibility with various surfactants and is stable across a wide pH range, making it versatile in product development. It is often incorporated into shampoos, conditioners, leave-in treatments, and styling products. In skincare, it can be found in moisturizers and serums, where it aids in improving the overall feel and appearance of the skin. Its film-forming properties also contribute to enhanced product performance and longevity on the skin or hair.
