Description

n-[3-(Dimethylamino)Propyl]Stearamide n-Oxide is a high-purity tertiary amine oxide surfactant derived from stearic acid. This compound is valued for its excellent foaming, wetting, and emulsifying properties, along with its mildness and compatibility with other formulation ingredients. It is a critical raw material for manufacturers in the personal care, home care, and industrial cleaning sectors seeking high-performance, stable surfactants.

Application

• Personal Care Formulations: Primary surfactant and foam booster in shampoos, body washes, facial cleansers, and shaving creams, prized for its mildness on skin and hair.
• Home Care Products: Key ingredient in liquid dish soaps, hard surface cleaners, and all-purpose cleaners for superior grease cutting and stable foam.
• Industrial & Institutional (I&I) Cleaners: Used in formulations for vehicle washes, food processing plant cleaners, and dairy detergents due to its robust performance.
• Textile Processing: Acts as a softener, lubricant, and antistatic agent in fiber and fabric treatment processes.
• Emulsion Stabilizer: Serves as a co-emulsifier and stabilizer in various cosmetic and industrial emulsion systems.
• Agricultural Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces.
