Description

Octoxynol 9 is a nonionic surfactant belonging to the alkylphenol ethoxylate family, widely recognized for its excellent wetting, emulsifying, and detergent properties. Its primary value lies in its ability to effectively reduce surface tension and solubilize a wide range of compounds, making it a versatile processing aid. This chemical is essential for manufacturers in the pharmaceutical, personal care, agrochemical, and industrial cleaning sectors who require a reliable and effective nonionic surfactant for their formulations.

Application

• Pharmaceuticals: Used as a solubilizer, emulsifier, and wetting agent in topical formulations, vaginal contraceptives, and as a spermicidal agent.
• Personal Care & Cosmetics: Functions as an emulsifier and cleansing agent in shampoos, liquid soaps, creams, and lotions.
• Agrochemicals: Acts as a key component in pesticide and herbicide formulations to enhance wetting, spreading, and penetration on plant surfaces.
• Industrial & Institutional Cleaning: Serves as a detergent and degreaser in heavy-duty cleaners, metalworking fluids, and textile processing aids.
• Paints & Coatings: Employed as a dispersant and emulsifier to stabilize pigment suspensions and improve application properties.
• Laboratory & Research: Used in biochemical applications, including cell lysis buffers and as a non-denaturing detergent for membrane protein isolation.
