Dioleyl phosphate

Dioleyl phosphate (CAS 14450-07-8), also known as dioleyl hydrogen phosphate, is a phosphate ester derived from oleyl alcohol used as a functional additive in industrial lubrication and surface treatment.

It combines lubricity with corrosion-inhibiting and surface-modifying properties, making it a practical choice for formulators working across metalworking, textile, and polymer processing applications.

In metalworking fluids and lubricant formulations, it acts as an extreme-pressure and anti-wear additive, forming a protective film on metal surfaces to reduce friction and inhibit corrosion.

Textile and leather processors use it as a fiber lubricant and softening agent, where its surface-active character improves processing performance and reduces fiber-to-metal friction during operations.

In plastics and polymer compounding, it functions as an internal lubricant and processing aid, improving melt flow and reducing die buildup during the manufacturing process.

It is also incorporated into specialty grease and oil formulations where both lubricity and metal surface protection are required simultaneously for high-performance industrial equipment.

Dioleyl phosphate is typically supplied as a liquid or viscous oil. It is available in technical grade, which is the standard specification for industrial lubricant and surface treatment applications.

Packaging options commonly include drums and intermediate bulk containers suited to industrial procurement volumes, ensuring safe transport and storage for large-scale chemical operations.
