Description

Oleth-4 is a nonionic surfactant belonging to the polyoxyethylene alkyl ether family, derived from oleyl alcohol. This versatile chemical is valued for its excellent emulsifying, solubilizing, and wetting properties, making it a critical component in formulations requiring stability and mildness. It is primarily used by manufacturers in the personal care, cosmetics, and pharmaceutical industries to create stable emulsions and enhance product performance.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and solubilizer in creams, lotions, and hair care products.
• Pharmaceuticals: Used as an excipient in topical ointments, creams, and emulsions for drug delivery.
• Industrial Emulsions: Serves as an emulsifying agent in the production of lubricants, textile processing aids, and agrochemical formulations.
• Household & Institutional Cleaners: Functions as a surfactant and wetting agent in liquid detergents and hard surface cleaners.
• Metalworking Fluids: Employed as an emulsifier and lubricity additive in soluble oils and coolants.
