What is Neopentyl Glycol Diheptanoate?

Neopentyl Glycol Diheptanoate is a synthetic diester derived from neopentyl glycol, a polyol, and heptanoic acid, a medium-chain fatty acid. It belongs to the class of emollient esters commonly used in cosmetics, particularly in makeup products like lipsticks, foundations, and anhydrous formulations. In skincare and color cosmetics, it functions by mimicking natural skin lipids to provide a non-greasy, dry-touch emolliency that enhances slip and spreadability. Its branched structure allows it to reduce product greasiness while maintaining stability, improving overall sensory attributes such as quick absorption and smooth application without stickiness. This ingredient helps formulate lightweight textures suitable for daily use across various product types.
