Quaternium-95

What is Quaternium-95?

Quaternium-95 is a synthetic quaternary ammonium compound, a type of cationic polymer created through chemical processes involving acrylamide derivatives and quaternization. Primarily used in rinse-off hair care items like shampoos, conditioners, and detanglers, it serves as a conditioning agent. Its positively charged structure attracts to the negatively charged hair surface, forming a thin protective layer. This action smooths raised cuticles, locks in moisture, reduces surface friction, and neutralizes static buildup. By improving slip between hair fibers, it eases detangling and enhances overall manageability without heavy residue. Its film-forming properties also contribute to a softer, more lustrous feel post-rinse, making it suitable for everyday hair maintenance routines in cosmetic formulations.
