Description

Octoxynol-3 is a nonionic surfactant belonging to the alkylphenol ethoxylate family, specifically a polyethylene glycol ether of octylphenol. Its balanced hydrophilic-lipophilic properties make it an effective wetting agent, emulsifier, and detergent. This product is essential for formulators in the personal care, agrochemical, and industrial cleaning sectors seeking reliable performance and material compatibility. Octoxynol-3 CAS NO 2315-67-5 is valued for its ability to stabilize formulations and enhance surface activity.

Application

• As an emulsifier and wetting agent in agricultural chemical formulations (e.g., herbicides, pesticides).
• A key surfactant in industrial and institutional (I&I) cleaning products and degreasers.
• Used in personal care products such as shampoos, liquid soaps, and cosmetic preparations.
• As a dispersing agent in textile processing and dyeing applications.
• An ingredient in metalworking fluids and industrial lubricants for its emulsifying properties.
• Employed in paint and coating formulations to improve pigment wetting and dispersion.
• As a solubilizer for fragrances and oils in various aqueous systems.
