Trimethylolpropane caprylate caprate

Trimethylolpropane caprylate caprate (CAS 11138-60-6) is a synthetic ester derived from trimethylolpropane with mixed C8/C10 fatty acids. Also marketed as Emkarate 1550 or Emkarate DE 155.

Where is Trimethylolpropane caprylate caprate used?

• Lubricants: synthetic base oil for compressor oils, refrigeration lubricants and high-temperature greases
• Personal care: emollient carrier and skin-feel modifier in creams, serums and colour cosmetics
• Polymer processing: plasticizer in PVC and polymer compounds, improving flexibility and processability
• Coatings and adhesives: reactive diluent or solvent carrier aiding application viscosity and film formation
• It functions as a base fluid and functional additive.

Good to know: Its light texture and oxidative stability distinguish it from mineral oil. Unlike phthalate-based options, it avoids associated regulatory concerns.

Commercial specifications

• Drum and IBC quantities
• Cosmetic grades meet purity and colour standards for personal care registration
