Tridecyl Neopentanoate

What is Tridecyl Neopentanoate?

Tridecyl Neopentanoate is a synthetic ester formed from tridecyl alcohol, a C13 fatty alcohol, and neopentanoic acid, a branched short-chain carboxylic acid. This clear, odorless liquid belongs to the class of alkyl esters commonly used in cosmetics for its unique sensory profile. It functions primarily as an emollient in skincare creams, lotions, sunscreens, and makeup products, where it lubricates the skin surface to reduce friction and improve spreadability. By mimicking natural skin lipids, it helps maintain the skin's barrier while offering a dry, velvety after-feel that avoids heaviness. Additionally, it acts as a binder in solid formulations like powders and bars, promoting ingredient adhesion, and serves as a skin conditioning agent to support overall skin suppleness without greasiness.
