Isodecyl stearate

Isodecyl stearate (CAS 31565-38-5) is an ester of stearic acid and isodecyl alcohol used as an emollient, lubricant, and plasticizer across personal care and industrial markets.

Its low-viscosity, non-greasy profile makes it a preferred choice where skin feel, spreadability, or surface lubrication are critical formulation criteria for high-performance products.

In cosmetics and personal care, it functions as an emollient and skin-conditioning agent in lotions, creams, color cosmetics, and sunscreens, improving texture and reducing drag on application.

Metalworking and industrial lubricant formulators incorporate it as a base fluid or additive to reduce friction and improve surface finish in various cutting and forming operations.

As a plasticizer, it is used in polymer and resin systems where flexibility and compatibility with non-polar matrices are required for long-term stability and material performance.

It also serves as a dispersing medium for pigments and actives in anhydrous formulations, where conventional aqueous systems are not suitable for the specific chemical requirements.

Isodecyl stearate is supplied as a clear to pale yellow liquid. It is available in cosmetic-grade and technical-grade specifications to meet the requirements of diverse manufacturers.

Bulk supply is standard in drums and IBCs, with packaging options varying by supplier and application to ensure safe transport and efficient handling in industrial facilities.
