Stearalkonium Chloride
What is Stearalkonium Chloride?
Stearalkonium Chloride is a quaternary ammonium salt, a synthetic cationic surfactant produced from fatty acids like stearic acid combined with a chloride ion. It features a positive charge that distinguishes it from typical anionic cleansers. Primarily featured in hair care formulations such as conditioners, leave-in treatments, and detangling sprays, it works by binding to the negatively charged keratin in hair fibers. This interaction neutralizes electrical charges to combat static, deposits a lubricating film for smoother comb-through, and enhances overall hair alignment. Its emulsifying capabilities help blend oils and water in products, while antimicrobial properties inhibit microbial growth. Regulatory assessments note its efficacy alongside considerations for concentration limits in rinse-off and leave-on applications to minimize risks.
