Quaternium-22

What is Quaternium-22?

Quaternium-22 is a quaternary ammonium compound derived from fatty acids, amines, and quaternizing agents through a chemical synthesis process. It belongs to the class of cationic polymers commonly employed in rinse-off and leave-on hair care formulations like conditioners, detanglers, and styling aids. In products, it works by adsorbing onto the negatively charged hair surface due to its positive charge, neutralizing static electricity, smoothing the cuticle, and depositing a thin film that enhances slip, detangling, and resistance to humidity. This mechanism improves overall hair texture without weighing it down, making it suitable for various hair types in daily grooming routines. Its amphoteric nature allows compatibility with anionic surfactants in shampoos, contributing to conditioning effects even in cleansing products.
