Isocetyl stearate

Isocetyl stearate (CAS 25339-09-7) is a branched-chain ester of stearic acid used as an emollient, lubricant, and plasticizer.

Where is Isocetyl stearate used?

• Cosmetics: emollient and texture enhancer in creams, lotions, lip products, and color cosmetics
• Coatings and sealants: plasticizer and softener for flexibility and substrate adhesion
• Adhesives and elastomers: reduces brittleness and improves processing
• Metalworking and industrial lubricants: non-reactive, film-forming ester in cutting fluids and release agents
• Its branched structure resists crystallization, keeping finished products smooth and spreadable at low temperatures.

Good to know: Cosmetic-grade material conforming to standard purity specifications is the most commonly traded form; technical-grade material is also available for industrial applications.
