Octadecylamine

Octadecylamine (CAS 124-30-1), also known as stearamine, is a long-chain primary amine derived from stearic acid. It functions as a surface-active agent and chemical intermediate.

This versatile compound serves as a corrosion inhibitor and chemical intermediate across a broad range of industrial manufacturing processes. It is essential for various high-performance applications.

In metalworking and lubricant formulations, it acts as a corrosion inhibitor and boundary lubricant additive. It forms a protective monolayer on metal surfaces to prevent oxidation and wear.

Textile and paper manufacturers use it as a softening and antistatic agent. This improves the handle of materials and significantly reduces static buildup in finished consumer and industrial goods.

In plastics processing, it functions as an internal lubricant and slip agent. It effectively reduces friction between polymer surfaces during complex extrusion and film production cycles.

Personal care formulators incorporate it into conditioning products and emulsions. It contributes to surface adhesion and emulsification performance in high-quality cosmetic formulations.

The product is supplied as a white to off-white waxy solid, typically in flake or pastille form. Technical grade is the most common offering, with purity levels ranging from 90% to 99%.

Specifications vary by supplier, and buyers should confirm amine value and purity profile. Ensure the material meets your specific application requirements before beginning large-scale production.
