Neopentyl Glycol Dicaprate

Neopentyl Glycol Dicaprate is a synthetic ester derived from neopentyl glycol and capric acid (a medium-chain fatty acid). It functions as an emollient and skin conditioning agent in skincare formulations.In products, it works to soften and smooth the skin surface by forming a light protective layer. It is valued in formulae for its ability to deliver conditioning benefits without the occlusive heaviness of some traditional emollients, making it suitable for a range of product types.

As an ester, Neopentyl Glycol Dicaprate works by penetrating the outer layer of skin and holding water within the stratum corneum—the skin's outermost barrier. This reduces transepidermal water loss (TEWL) and maintains skin hydration.Its molecular structure allows it to be absorbed relatively quickly, which is why it avoids the occlusive, greasy feeling associated with heavier oils and butters. This makes it particularly useful in lightweight serums, moisturisers, and day creams where a polished finish is desired.

Neopentyl Glycol Dicaprate is typically used as a supporting ingredient in formulations rather than a standalone treatment. Look for it in moisturisers, serums, and body care products where it works alongside humectants and other emollients to optimise hydration and feel. As it is rarely the sole active ingredient, apply products containing it as directed on the label.

Generally well-tolerated and considered safe for use in cosmetics at typical concentrations. No significant irritancy or sensitising potential has been documented.
