Description

(Carboxymethyl)Dodecyldimethylammonium Chloride is a high-purity quaternary ammonium compound, also known as a carboxybetaine surfactant. This amphoteric molecule is valued for its excellent surface activity, stability across a wide pH range, and compatibility with other ionic species. It serves as a critical raw material for formulators in the personal care, home care, and industrial cleaning sectors seeking mild yet effective performance. Its unique structure provides both cationic and anionic functionality, making it a versatile ingredient for specialized applications.

Application

• Personal Care Formulations: Used as a primary or co-surfactant in mild shampoos, body washes, and facial cleansers, where it provides gentle cleansing and foam boosting.
• Home Care & Detergents: Incorporated into liquid laundry detergents and hard surface cleaners for its superior wetting, emulsifying, and anti-redeposition properties.
• Industrial & Institutional (I&I) Cleaning: A key component in formulations for food processing plants, dairies, and healthcare facilities due to its efficacy and stability in hard water.
• Oilfield Chemicals: Acts as a corrosion inhibitor and surfactant in drilling fluids and enhanced oil recovery (EOR) processes.
• Textile & Leather Processing: Functions as a softener, leveling agent, and antistatic agent in dyeing and finishing baths.
• Biotechnology & Pharmaceuticals: Employed in cell lysis buffers and as a mild solubilizing agent for membrane proteins.
