Description

Hexadecyldimethylamine n-Oxide is a high-purity, amphoteric surfactant belonging to the amine oxide chemical class. This compound is valued for its excellent foaming, wetting, and emulsifying properties, along with its mildness and compatibility with other formulation ingredients. It serves as a critical performance additive for manufacturers in the personal care, home care, and industrial cleaning sectors seeking to enhance product efficacy and stability.

Application

• Personal Care Formulations: Used as a primary or secondary surfactant in shampoos, body washes, and facial cleansers for its rich, stable foam and skin-mildness.
• Household & Institutional Cleaners: Acts as a foam booster and viscosity modifier in dishwashing liquids, hard surface cleaners, and all-purpose cleaners.
• Industrial & Textile Processing: Employed as a wetting agent, emulsifier, and antistatic agent in textile auxiliaries and industrial degreasers.
• Biochemical Research: Utilized as a mild, non-denaturing detergent for membrane protein solubilization in laboratory settings.
• Agricultural Adjuvants: Functions as a surfactant to improve the spreading and adhesion of pesticides and herbicides on plant surfaces.
