C20-22-alkyltrimethylammonium chlorides

C20-22-Alkyltrimethylammonium Chlorides (CAS 68607-24-9) is a long-chain quaternary ammonium surfactant derived from C20-C22 fatty alkyl groups.

Where is C20-22-alkyltrimethylammonium chlorides used?

• Personal care: primary conditioning agent in hair rinses and leave-in treatments, reducing static and improving combability through substantivity to negatively charged hair fibers
• Industrial and institutional cleaning: biocidal active effective against bacteria and fungi on hard surfaces
• Water treatment: controls microbial growth in cooling towers and process water systems
• Textile finishing: imparts softness and antistatic properties to fiber substrates
• Its extended carbon chain length delivers stronger surface adsorption and antimicrobial performance.

Good to know: The extended carbon chain length distinguishes it from shorter-chain quats. Buyers should confirm active content specification and counterion purity when evaluating suppliers for regulated applications.
