Distearyl ether

Distearyl ether (CAS 6297-03-6), also known as dioctadecyl ether, is a long-chain symmetrical ether derived from stearyl alcohol used across personal care, industrial lubrication, and polymer processing.

It functions as a lubricant, emollient, and plasticizing agent, providing slip, softness, and processing efficiency in finished formulations. In personal care, it is incorporated into skin creams and hair conditioners.

The material is used in color cosmetics to deliver a smooth, non-greasy skin feel and improve product spreadability. Industrial lubricant formulators use it as a base component or additive in metalworking fluids.

It is ideal for release agents where low-reactivity and high-temperature stability are required. Textile and leather processors apply it as a fiber lubricant and softening agent to reduce friction during mechanical processing.

This chemical improves handle in finished fabrics and serves plastics compounding as an internal or external lubricant. It helps to reduce melt viscosity and prevent die buildup during extrusion and molding operations.

Distearyl ether is supplied as a white to off-white waxy solid, typically in flake or pastille form. Technical and cosmetic grades are the most commonly available for various industrial and commercial needs.

Cosmetic-grade material meets purity requirements suitable for personal care formulation. Bulk supply is standard for industrial buyers, with smaller pack sizes available for specialty applications.
