Description

Oleth-5 is a non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, derived from oleyl alcohol. This versatile chemical is valued for its excellent emulsifying, wetting, and solubilizing properties in a wide range of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, pharmaceutical, and industrial cleaning sectors seeking reliable performance and mildness.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and solubilizer in creams, lotions, hair conditioners, and makeup products, providing stable emulsions and a smooth skin feel.
• Pharmaceutical Preparations: Used as an emulsifying agent in topical ointments, creams, and lotions, and as a solubilizer for active pharmaceutical ingredients.
• Industrial & Institutional Cleaners: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and textile processing aids due to its effective wetting and emulsification of oils.
• Agricultural Adjuvants: Enhances the spreading and penetration of pesticides and herbicides on plant surfaces, improving efficacy.
• Textile Processing: Functions as a lubricant, softener, and dyeing assistant in fiber and fabric treatment processes.
• Paints & Coatings: Used as a dispersing agent and emulsifier in water-based paint systems to improve pigment stability and application properties.
