Description

Dodecyl(2-Hydroxyethyl)Dimethylammonium Methanesulphonate is a quaternary ammonium compound valued for its cationic surfactant properties and efficacy as a phase-transfer catalyst. Its structure makes it particularly useful in formulations requiring a combination of surface activity, antimicrobial action, and solubility in both aqueous and organic media. This chemical is essential for manufacturers in the personal care, agrochemical, and specialty chemical synthesis sectors seeking reliable, high-performance ingredients.

Application

• As a cationic surfactant and emulsifier in hair conditioners, fabric softeners, and other personal care formulations.
• As a phase-transfer catalyst (PTC) in organic synthesis, facilitating reactions between reagents in immiscible phases.
• As an active ingredient or formulation adjuvant in biocidal products and disinfectants.
• In the synthesis of specialty chemicals and polymers where its quaternary ammonium structure is incorporated.
• As a corrosion inhibitor and additive in industrial fluids and coatings.
• In agrochemical formulations as a compatibilizer and penetration enhancer.
