Description

Alcohols, C16-18 And C18-Unsatd. is a defined blend of long-chain fatty alcohols, primarily consisting of cetyl, stearyl, and oleyl alcohol components. This mixture is valued for its versatile surfactant and emollient properties, which are essential for creating stable formulations and modifying physical characteristics. It is a critical raw material for manufacturers in the personal care, cosmetics, and industrial lubricant sectors seeking consistent performance and quality.

Application

• Personal Care & Cosmetics: A key emollient and opacifying agent in creams, lotions, hair conditioners, and deodorant sticks.
• Surfactant & Detergent Intermediates: Used in the production of nonionic surfactants (ethoxylates) for industrial and household cleaners.
• Lubricants & Metalworking Fluids: Acts as a friction modifier and emulsifier in synthetic and semi-synthetic lubricant formulations.
• Textile & Leather Processing: Employed as a softener, lubricant, and anti-static agent in fiber and leather treatment.
• Plastic & Polymer Additives: Functions as an internal and external lubricant and slip agent in polymer processing.
• Pharmaceutical Ointments: Serves as a consistency regulator and stabilizer in topical ointment and cream bases.
