Description

Octoxynol-8 is a nonionic surfactant belonging to the alkylphenol ethoxylate family, widely recognized for its excellent wetting, emulsifying, and dispersing properties. This versatility makes it a critical component in formulating products where surface tension reduction and stability are paramount. Key industries that rely on this surfactant include pharmaceuticals, agrochemicals, industrial cleaning, and personal care, where it functions as a solubilizer, detergent, and processing aid.

Application

• Pharmaceutical formulations as a solubilizing agent for active ingredients.
• Agricultural chemical emulsions and dispersions for pesticides and herbicides.
• Industrial and institutional cleaning products for degreasing and wetting.
• Personal care products, including shampoos and lotions, as an emulsifier.
• Textile processing aids for scouring and dye leveling.
• Metalworking fluids and industrial lubricants for emulsion stabilization.
• Latex and polymer emulsion stabilization in paint and coating formulations.
• Research and development as a standard nonionic surfactant for laboratory studies.
