Description

n-(2-Hydroxyethyl)Octadecanamide is a high-purity fatty acid alkanolamide derivative, specifically the ethanolamide of stearic acid. This compound serves as a versatile non-ionic surfactant and emulsifying agent, prized for its thickening and foam-stabilizing properties. It is essential for formulators in the personal care, cosmetics, and industrial cleaning sectors seeking effective, mild, and stable ingredients.

Application

• Personal Care & Cosmetics: Acts as a primary thickener, opacifier, and pearlizing agent in shampoos, liquid soaps, shower gels, and cream-based formulations.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaning fluids, and floor cleaners for its excellent emulsification and soil suspension capabilities.
• Textile & Leather Processing: Functions as a softener, lubricant, and anti-static agent in fiber processing and leather finishing applications.
• Agricultural Adjuvants: Employed as a surfactant and dispersant in pesticide and herbicide formulations to enhance spreading and adherence.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid, improving color development and stability in various coating systems.
• Metalworking Fluids: Provides lubrication and corrosion inhibition in synthetic and semi-synthetic cutting and grinding fluids.
