Isotridecyl stearate

Isotridecyl stearate (CAS 31565-37-4), also marketed as Exceparl TD-S, is a branched-chain ester of stearic acid and isotridecyl alcohol used as an emollient and lubricant.

Where is Isotridecyl stearate used?

• Personal care: skin-conditioning emollient in creams, lotions and color cosmetics, with a smooth, non-tacky after-feel
• Industrial lubricants: base fluid or additive in metalworking fluids and release agents
• Polymer and elastomer compounding: plasticizer and softener improving flexibility and processability
• Coatings and adhesives: film-flexibility modifier
• Its branched molecular structure resists crystallization, keeping formulations fluid and stable.
