Polyquaternium-30

What is Polyquaternium-30?

Polyquaternium-30 is a synthetic, high-molecular-weight cationic copolymer derived from acrylamide and diallyldimethylammonium chloride monomers. Developed specifically for cosmetic applications, it belongs to the polyquaternium family of conditioning polymers. Primarily featured in hair care products such as conditioners, shampoos, detanglers, and styling sprays, it functions by depositing a thin, positively charged layer onto the negatively charged hair surface. This interaction neutralizes static electricity, enhances slip for easier combing, and creates a flexible film that improves smoothness, shine, and resistance to humidity. In some formulations, it also contributes to skin products by forming sheer barriers for better product adherence and water repellency, aiding in makeup longevity or sun protection wear.
