Description

Hexadecylbetaine is a high-purity amphoteric surfactant belonging to the alkyl betaine class, characterized by its excellent mildness, foam stability, and compatibility with other surfactants. Its unique structure provides superior conditioning and viscosity-building properties, making it a versatile ingredient for demanding formulations. This compound is essential for manufacturers in the personal care, home care, and industrial cleaning sectors seeking high-performance, skin-friendly additives.

Application

• Personal Care Products: A key mild surfactant and foam booster in shampoos, body washes, facial cleansers, and baby care products.
• Home Care & Detergents: Used in liquid dish soaps, hard surface cleaners, and laundry detergents for its grease-cutting ability and foam stability.
• Industrial & Institutional (I&I) Cleaning: Formulated into high-performance cleaners, degreasers, and vehicle wash systems.
• Cosmetic Formulations: Acts as a conditioning agent and viscosity modifier in creams, lotions, and shaving products.
• Oilfield Chemicals: Employed in drilling muds and well stimulation fluids as a foaming and viscoelastic agent.
• Textile & Leather Processing: Serves as a softener, leveling agent, and auxiliary in dyeing and finishing processes.
