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. The extended carbon chain length distinguishes it from shorter-chain quats.

This chemical structure delivers stronger surface adsorption and antimicrobial performance across conditioning, preservation, and surface-treatment applications. In personal care, it functions as a primary conditioning agent.

It is used in hair rinses and leave-in treatments, where its substantivity to negatively charged hair fibers reduces static and improves combability. Industrial and institutional cleaning formulations incorporate it as a biocidal active.

It is effective against a broad spectrum of bacteria and fungi on hard surfaces. Water treatment programs use it to control microbial growth in cooling towers and process water systems where persistent activity is required.

Surface activity at low dosage levels is commercially valuable for many industrial processes. Fabric softeners and textile finishing products also rely on it to impart softness and antistatic properties to fiber substrates.

C20-22-Alkyltrimethylammonium Chlorides is typically supplied as an aqueous solution or paste, with active content varying by grade. Technical and industrial grades are the most common market forms available.

Cosmetic-grade material is also available to meet specific personal care formulation requirements. Buyers should confirm active content specification and counterion purity when evaluating suppliers for regulated applications.
