Description

Diammonium Octadecyl Phosphate is an organophosphate salt with surfactant and emulsifying properties. This compound is valued for its ability to modify surface tension and act as a stable emulsifier in complex formulations. It is primarily utilized by manufacturers in the personal care, textile, and industrial lubricant sectors seeking effective phosphate ester-based additives.

Application

• Primary emulsifier and stabilizer in cosmetic and personal care creams and lotions.
• Textile processing aid, functioning as a softener, antistatic agent, and lubricant for fibers.
• Corrosion inhibitor and anti-wear additive in industrial lubricants and metalworking fluids.
• Dispersing agent and processing aid in pigment and dye preparations.
• Emulsifier and coupling agent in agricultural pesticide and herbicide formulations.
• Raw material for the synthesis of more complex phosphate ester surfactants.
