Description

Fatty Acids, C16-18, Ethoxylated CAS NO 68989-61-7 is a non-ionic surfactant derived from the ethoxylation of a blend of C16 (palmitic) and C18 (stearic) fatty acids. This versatile chemical intermediate is prized for its excellent emulsifying, dispersing, and wetting properties, making it a critical component in formulating stable and effective industrial products. It is essential for manufacturers in the personal care, textile processing, agrochemical, and industrial cleaning sectors seeking reliable performance and formulation flexibility.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and opacifier in creams, lotions, and hair conditioners, providing a rich, stable texture.
• Textile Processing: Used as a lubricant, softener, and antistatic agent in fiber spinning and fabric finishing to improve handle and processability.
• Industrial & Institutional (I&I) Cleaning: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and floor care formulations for superior emulsification of oils.
• Agrochemicals: Functions as an emulsifier and wetting agent in pesticide and herbicide formulations, enhancing spray coverage and active ingredient delivery.
• Paints & Coatings: Employed as a dispersing agent for pigments and fillers, improving color development and stability in water-based systems.
• Leather Processing: Used in fatliquoring and softening stages to impart suppleness and a uniform finish to leather goods.
