Isodecyl Neopentanoate Good Emollient Hydration Isodecyl Neopentanoate at a glance Synthetic emollient that also helps product flow Delivers silicone-like esthetics with a light, dry finish Helps oil-soluble ingredients penetrate skin more effectively Made from fatty alcohols and a short-chain fatty acid Isodecyl Neopentanoate description Isodecyl neopentanoate is a synthetic emollient ester made from fatty alcohols and the short-chain fatty acid neopentanoic acid. It has silicone-like aesthetics and is used for a wide variety of purposes in cosmetics, including as an emollient. In addition, it leaves a dry, silky finish and can help deliver oil-soluble ingredients in to skin’s uppermost layers. Isodecyl neopentanoate also works to modify the rheology of cosmetic formulas, which is a fancy way to say it can positively impact a product’s flow, such as how quickly a sunscreen or shampoo is dispensed (does it flow freely or do you really have to work to get product out?). Usage levels of isodecyl neopentanoate in cosmetics ranges from 5–10%, although amounts lower than this may be present when this ingredient is part of a blend. It has been evaluated and deemed safe as used in cosmetics, assuming such products are formulated to be non-irritating. Related ingredients: Ester Octyldodecyl Neopentanoate
