Stearyl stearate

Stearyl stearate (CAS 2778-96-3 ), also known as octadecyl stearate, is a waxy ester derived from stearic acid and stearyl alcohol used across personal care, industrial lubricant, and polymer processing applications.

It functions as a lubricant, plasticizer, and consistency agent, providing controlled slip, texture modification, and processing efficiency depending on the specific formulation requirements of the end user.

In personal care, it is incorporated into lipsticks, creams, and solid emulsions to build structure, improve spreadability, and modify skin feel without adding any unwanted greasiness to the final product.

Polymer and rubber compounders use it as an internal or external lubricant to reduce melt viscosity and prevent die buildup during extrusion and calendering processes for various industrial materials.

In metalworking and industrial lubrication, it functions as a solid lubricant component in greases and release agents where high-temperature stability and low migration are considered top priorities.

Textile and leather finishing operations apply it as a softening agent to improve hand feel and surface slip on treated substrates, ensuring a high-quality finish for consumer and industrial goods.

Stearyl stearate is supplied as a white to off-white waxy solid, typically in flake or pastille form suited for melt blending and direct weighing in large scale manufacturing environments.

Technical and cosmetic grades are the most commonly available, with cosmetic-grade material meeting purity requirements for personal care formulations. Bulk supply is standard for industrial buyers.
