Isobutyl stearate

Isobutyl stearate (CAS 646-13-9) is a synthetic ester of stearic acid and isobutyl alcohol used across personal care, lubrication, and polymer processing. It functions as an emollient, plasticizer, and carrier fluid.

This chemical provides a dry, non-greasy feel in formulations and effectively reduces friction in industrial systems. In personal care, it is incorporated into skin creams, color cosmetics, and hair conditioners.

It acts as an emollient and spreading agent that improves texture without leaving a heavy residue. Metalworking and industrial lubricant formulators use it as a base fluid or additive to reduce friction.

It is frequently utilized in cutting oils and release agents to minimize wear. In plastics processing, it acts as an external lubricant and plasticizer for PVC and other polymers, improving flow during extrusion.

The product also serves as a solvent and carrier for pigment dispersions and active ingredients in both cosmetic and industrial coating applications. It is supplied as a clear to pale yellow liquid.

It is available in technical and cosmetic grades, with cosmetic-grade material meeting purity standards relevant to personal care manufacturing. Bulk supply is standard in drums and IBC containers.

Cosmetic-grade batches are typically accompanied by full documentation including COA and safety data. This ensures compliance with rigorous industry requirements for quality and safety in diverse applications.
