Polyquaternium-59
What is Polyquaternium-59?
Polyquaternium-59 is a synthetic, water-soluble cationic polymer derived from acrylamide and diallyldimethylammonium chloride monomers. Belonging to the polyquaternium family, it appears in hair care products like shampoos, conditioners, and detanglers. Its quaternary ammonium structure carries a positive charge, enabling strong adhesion to the negatively charged keratin in hair and skin surfaces. This interaction creates a lightweight, flexible film that lubricates strands, reduces surface friction, and neutralizes static buildup. By smoothing the hair cuticle, it facilitates easier combing in both wet and dry states, enhances shine, and improves overall handle without heaviness. Primarily suited for rinse-off applications, it delivers targeted conditioning during use, supporting hair manageability across various types.
