Description

Octadecen-1-Ol, Phosphate, Sodium Salt is an organophosphate surfactant and anionic emulsifier derived from oleyl alcohol. This compound matters for its ability to effectively reduce surface tension and stabilize emulsions in complex formulations. Industrial manufacturers in sectors such as agrochemicals, textiles, and personal care need it for its reliable performance as a wetting agent, dispersant, and emulsifier.

Application

• Primary emulsifier and wetting agent in agricultural pesticide and herbicide formulations.
• Dispersing agent for pigments and fillers in textile processing and dyeing.
• Key ingredient in industrial cleaning products and metalworking fluids for its surfactant properties.
• Functional component in personal care products like creams and lotions for emulsion stabilization.
• Used as an antistatic agent and processing aid in polymer and plastic production.
• Intermediate in the synthesis of more complex specialty surfactants and phosphate esters.
