Propylene glycol monoisostearate

Propylene glycol monoisostearate (CAS 68171-38-0) is a propylene glycol ester of isostearic acid used as an emulsifier, humectant, and softening agent across personal care and industrial formulations.

Its branched fatty acid structure keeps it liquid at room temperature, making it practical for formulations where solid emulsifiers create processing challenges for manufacturers.

In skin and hair care, it functions as an emulsifier and moisturizing agent in creams, lotions, and conditioners, helping stabilize oil-in-water and water-in-oil systems.

The chemical contributes a smooth skin feel while coating formulators use it as a plasticizer and dispersing aid to improve film flexibility and pigment wetting in specialty coatings.

In textile and leather processing, it acts as a softener and lubricant applied during finishing to improve handle and reduce fiber stiffness across various materials.

Adhesive and sealant manufacturers incorporate it as a plasticizing component to adjust tack and flexibility in elastomeric formulations for industrial and commercial use.

Propylene glycol monoisostearate is supplied as a clear to pale yellow viscous liquid. It is available in technical and cosmetic grades for diverse industrial requirements.

Cosmetic-grade material meets purity requirements suitable for personal care applications. Bulk supply is standard in drums and intermediate bulk containers (IBCs).
