Neopentyl glycol diheptanoate

Neopentyl glycol diheptanoate (CAS 68855-18-5) is a synthetic diester built from neopentyl glycol and heptanoic acid, used across lubricant and personal care formulations as an emollient base, functional lubricant, and plasticizer.

Its ester structure delivers oxidative stability and low volatility that matter directly to formulators selecting base fluids or skin-feel agents. In lubricant and metalworking formulations, it functions as a synthetic base fluid or co-base.

The compound offers strong thermal stability and low deposit formation in compressor oils, gear fluids, and industrial process lubricants. Automotive applications include use in specialty lubricants where synthetic esters are specified for extended drain intervals.

It ensures compatibility with elastomer seals in various mechanical systems. Personal care formulators incorporate it as an em
