Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-(9Z)-1-Oxo-9-Octadecenyl-.Omega.-Butoxy- is a specialized non-ionic surfactant and emulsifier derived from oleic acid and poly(ethylene glycol) butyl ether. This compound matters for its ability to effectively stabilize emulsions and modify surface tension in complex formulations, offering a balance of lipophilic and hydrophilic properties. It is needed by manufacturers in the cosmetics, agrochemicals, and industrial lubricant sectors seeking reliable performance ingredients. The CAS number for this substance is 37281-78-0.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and ointments, ensuring smooth texture and long-term stability.
• Agrochemical Concentrates: Used as a key component in pesticide and herbicide emulsifiable concentrates (ECs) to improve dispersion and wetting on plant surfaces.
• Industrial Lubricants & Metalworking Fluids: Serves as an emulsifier and anti-wear additive, enhancing the performance and stability of oil-in-water lubricants.
• Textile Processing: Functions as a softening agent, lubricant, and anti-static agent in fiber production and fabric finishing.
• Paints & Coatings: Employed as a dispersing agent and flow improver to ensure uniform pigment distribution and smooth application.
• Cleaning & Detergent Formulations: Enhances the cleaning efficacy of industrial and institutional cleaners by improving soil emulsification and removal.
