Trimethylolpropane caprylate caprate

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

It functions as a high-performance base fluid and functional additive across lubrication, personal care, and polymer processing applications. In lubricant formulations, it serves as a synthetic base oil.

This material is ideal for compressor oils, refrigeration lubricants, and high-temperature greases where thermal stability and low volatility are critical selection criteria for industrial manufacturers.

Personal care manufacturers incorporate it as an emollient carrier and skin-feel modifier in creams, serums, and color cosmetics. Its light texture and oxidative stability distinguish it from mineral oil.

As a plasticizer in PVC and polymer compounds, it improves flexibility and processability without the regulatory concerns associated with phthalate-based options. It is a versatile choice for modern compounding.

In coatings and adhesive systems, it acts as a reactive diluent or solvent carrier, aiding application viscosity and film formation. This ensures consistent performance across various industrial coating applications.

The product is supplied as a clear, low-viscosity liquid in drum and IBC quantities. Cosmetic-grade and technical-grade specifications are the most commonly available for global distribution.

Cosmetic grades typically meet purity and color standards required for personal care registration. Bulk supply is standard for industrial lubricant and polymer processing customers worldwide.
