Description

Octoxynol-5 is a nonionic surfactant belonging to the alkylphenol ethoxylate family, specifically a p-(1,1,3,3-tetramethylbutyl)phenol polymer with an average of 5 moles of ethylene oxide. This compound is valued for its effective wetting, emulsifying, and dispersing properties in aqueous systems. It is primarily utilized in industrial formulations, including agrochemicals, textile processing, and as a component in cleaning and detergent products where controlled hydrophilicity is required.

Application

• Primary emulsifier and wetting agent in agricultural chemical formulations (herbicides, insecticides).
• Detergent and cleaning agent component for industrial and institutional (I&I) applications.
• Textile processing aid for scouring, dyeing, and finishing operations.
• Intermediate in the synthesis of other specialty surfactants and chemical derivatives.
• Dispersing agent for pigments and fillers in various industrial preparations.
• Foam control agent and stabilizer in specific manufacturing processes.
