Triheptanoin
What is Triheptanoin?
Triheptanoin is a clear, odorless synthetic ester produced by esterifying glycerol with heptanoic acid, a seven-carbon saturated fatty acid. It belongs to the class of medium-chain triglycerides commonly employed in skincare and makeup as an emollient. In formulations, it delivers a smooth, non-oily lubricity, helping to lock in moisture by creating a breathable barrier on the skin. Its low viscosity allows it to thin heavier oils, improving spreadability and reducing tackiness in creams, lotions, and serums. As a multifunctional ingredient, it modifies product thickness for optimal sensory feel and aids in blending oil and water phases. Frequently appears in facial moisturizers, primers, and cleansers, prized for enhancing usability without heaviness.
