Propylene glycol isostearate

Propylene glycol isostearate (CAS 1366396-43-1) is an ester of propylene glycol and isostearic acid used as an emollient, emulsifier, and lubricant across personal care and industrial formulations.

Its branched fatty acid structure resists crystallization, making it effective in applications where low-temperature stability and skin-feel are purchasing priorities for manufacturers.

In cosmetics and personal care, it functions as an emollient and co-emulsifier in creams, lotions, and color cosmetics, contributing to smooth spreadability and skin conditioning without a heavy residue.

Coating and adhesive formulators incorporate it as a plasticizer and wetting agent to improve substrate adhesion and film flexibility. It is highly valued for its consistent performance in diverse environments.

In lubricant and metalworking compounds, it acts as a boundary lubricant and corrosion-inhibiting carrier in cutting fluids and release agents. This ensures high efficiency in heavy industrial processes.

It also serves industrial sealant and elastomer formulations where a non-crystallizing, low-viscosity ester is required for processing compatibility. This versatility makes it a staple in chemical manufacturing.

Propylene glycol isostearate is supplied as a clear to pale yellow liquid. It is available in cosmetic-grade and technical-grade specifications to meet the purity requirements of various end markets.
