Description

Oleth-16 CAS NO 25190-05-0 is a non-ionic surfactant belonging to the polyoxyethylene alkyl ether (oleth) family, widely valued for its excellent emulsifying, solubilizing, and wetting properties. This chemical is critical for formulators seeking to create stable, high-performance emulsions and enhance the delivery of active ingredients. It is an essential component for manufacturers in the personal care, cosmetics, pharmaceutical, and industrial cleaning sectors.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and solubilizer in creams, lotions, hair conditioners, and makeup products.
• Pharmaceutical Preparations: Used as an emulsifying agent in topical ointments, creams, and lotions to improve drug delivery and stability.
• Industrial & Institutional Cleaners: Serves as a key surfactant in heavy-duty degreasers, metal cleaners, and textile processing aids for its superior wetting and cleaning power.
• Agricultural Adjuvants: Functions as a wetting agent and emulsifier in pesticide and herbicide formulations to improve spray coverage and efficacy.
• Lubricant & Metalworking Fluids: Employed as an emulsifier and lubricity additive in soluble oils and coolants.
• Paints & Coatings: Used as a dispersing and wetting agent to improve pigment dispersion and application properties.
