Trimethylolpropane triisostearate

Trimethylolpropane triisostearate (CAS 68541-50-4) is a branched-chain triester of trimethylolpropane and isostearic acid. Also marketed as Crodamol TTIS and Pelemol TMPIS.

Where is Trimethylolpropane triisostearate used?

• Personal care: emollient that conditions skin and hair, improving spreadability in lipsticks, foundations and color cosmetics
• Coatings and sealants: plasticizer improving flexibility and adhesion without compromising film integrity
• Polymer processing: softens and modifies the rheology of elastomers and thermoplastic compounds during compounding
• Industrial lubricants: base fluid or additive where high thermal stability and low volatility are required in metalworking and machinery
• It functions as a plasticizer and lubricant in industrial coatings.

Good to know: Its low polarity and oxidative stability make it an alternative to silicones and mineral oil.

Commercial specifications

• Bulk supply in drums and IBCs; smaller packaging for specialty and laboratory use
