Description

Poly(Oxy-1,2-Ethanediyl), α-(1-Oxooctyl)-ω- Hydroxy-, Eo 3-10 Mol is a non-ionic surfactant belonging to the class of polyethylene glycol (PEG) esters of fatty acids, specifically caprylic acid. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a versatile functional additive. It is primarily used in industrial formulations where controlled hydrophilicity and compatibility with various chemical systems are required.

Application

• Industrial Emulsifier: Used in the formulation of cutting oils, metalworking fluids, and lubricants for stable oil-in-water emulsions.
• Textile Processing Aid: Acts as a wetting agent, leveling agent, and dye dispersant in textile dyeing and finishing operations.
• Agricultural Adjuvant: Enhances the spreading and penetration of pesticides, herbicides, and fungicides on plant surfaces.
• Paint & Coating Additive: Serves as a pigment grinding aid and dispersant to improve color development and stability in water-based systems.
• Cleaning & Detergent Formulations: Functions as a surfactant and degreaser in industrial and institutional cleaning products.
• Personal Care Intermediate: Utilized as an emulsifier and solubilizer in the production of creams, lotions, and other cosmetic products.
• Plastic & Polymer Additive: Acts as an internal or external lubricant and antistatic agent in polymer processing.
