Description

Octoxynol-8 is a non-ionic surfactant belonging to the alkylphenol ethoxylate family, widely recognized for its excellent wetting, emulsifying, and detergent properties. Its balanced hydrophilic-lipophilic character makes it a versatile and effective component in formulations requiring stable emulsions and thorough surface penetration. This product is essential for manufacturers in the pharmaceutical, personal care, agrochemical, and industrial cleaning sectors seeking reliable performance and formulation stability. It is also known under the CAS registry number 3520-90-9.

Application

• Pharmaceutical Formulations: Used as an emulsifier, solubilizer, and wetting agent in topical creams, ointments, and lotions.
• Personal Care & Cosmetics: Key ingredient in shampoos, liquid soaps, and skincare products for its cleansing and foam-boosting properties.
• Agrochemicals: Acts as an adjuvant in pesticide and herbicide formulations to enhance spray coverage and active ingredient penetration.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in hard surface cleaners, degreasers, and textile processing aids.
• Emulsion Polymerization: Functions as an emulsifier and stabilizer in the production of synthetic latexes and polymers.
• Metalworking Fluids: Employed as an emulsifier in coolants and cutting fluids to stabilize oil-in-water emulsions.
