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.

Where is Propylene glycol monoisostearate used?

• Skin and hair care: emulsifier and moisturizing agent in creams, lotions, and conditioners, stabilizing oil-in-water and water-in-oil systems
• Coatings: plasticizer and dispersing aid improving film flexibility and pigment wetting
• Textile and leather processing: softener and lubricant applied during finishing to improve handle and reduce fiber stiffness
• Adhesives and sealants: plasticizing component adjusting tack and flexibility in elastomeric formulations
• Its branched fatty acid structure keeps it liquid at room temperature, making it practical where solid emulsifiers create processing challenges.

Commercial specifications

• Cosmetic grade meets purity requirements for personal care
• Bulk supply in drums and intermediate bulk containers (IBCs)
