Polyquaternium-64
What is Polyquaternium-64?
Polyquaternium-64 is a synthetic cationic copolymer primarily composed of vinylpyrrolidone and quaternized methacrylamidopropyl monomers. It carries a positive charge, enabling strong adhesion to hair's negatively charged surface. Commonly found in shampoos, conditioners, and styling products within the hair care category, it functions by depositing a thin, flexible film on hair shafts. This film smooths raised cuticles, minimizes inter-fiber friction for detangling, neutralizes static electricity, and shields against humidity. Additionally, its humectant-like action helps draw and retain moisture on hair, promoting suppleness without greasiness. The polymer's film-forming properties also aid in style hold and protection from environmental stressors, making it suitable for daily use in rinse-off and leave-on formulations.
