Description

Oleth-3 is a non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, derived from oleyl alcohol. This versatile compound is valued for its excellent emulsifying, solubilizing, and wetting properties in a wide range of formulations. It serves as a critical ingredient for industrial manufacturers and formulators in the personal care, pharmaceutical, and agrochemical sectors, where stable and effective emulsions are required.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and solubilizer in creams, lotions, hair conditioners, and makeup products, providing a smooth texture and stable formulations.
• Pharmaceuticals: Used as an emulsifying agent in topical ointments, creams, and lotions to ensure uniform drug delivery and product stability.
• Agrochemicals: Functions as a wetting agent and emulsifier in pesticide and herbicide formulations, enhancing spray coverage and active ingredient dispersion.
• Industrial Cleaners & Detergents: Serves as a surfactant in heavy-duty cleaning products and textile processing aids for effective soil removal and emulsification of oils.
• Metalworking Fluids: Employed as an emulsifier in soluble oils and coolants to stabilize oil-in-water emulsions for lubrication and cooling.
• Paints & Coatings: Aids in pigment wetting and dispersion in water-based paint systems, improving color development and application properties.
