Description

Nonoxynol 9 is a nonionic surfactant belonging to the alkylphenol ethoxylate family, widely recognized for its potent surface-active and spermicidal properties. Its primary commercial value lies in its ability to effectively reduce surface tension, emulsify, and disperse, making it a versatile ingredient in demanding formulations. This product is essential for manufacturers in the pharmaceutical, personal care, and industrial cleaning sectors seeking a reliable and well-characterized raw material.

Application

• Spermicidal Agent: A key active ingredient in contraceptive foams, gels, creams, and films.
• Pharmaceutical Excipient: Used as an emulsifier, solubilizer, and wetting agent in topical and vaginal drug delivery systems.
• Personal Care Formulations: Functions as an emulsifier and surfactant in shampoos, intimate washes, and other cleansing products.
• Industrial & Institutional (I&I) Cleaning: Employed in detergent formulations for hard surface cleaning, where its emulsifying power is valuable.
• Textile Processing: Acts as a wetting agent, dispersant, and emulsifier in various textile auxiliaries and dyeing processes.
• Agricultural Adjuvants: Used in pesticide formulations to enhance spreading and adhesion on plant surfaces.
