What Is Isostearyl Neopentanoate?

Isostearyl neopentanoate is the ester of the fatty alcohol isostearyl alcohol and the carboxylic acid neopentanoic acid. Its listed cosmetic functions include emollient and binding agent. It can also function as a solvent for certain UV absorbers.\n\nIsostearyl neopentanoate is noted in research for contributing lubricity and helping skin care formulations, such as moisturizers and sunscreens, spread more easily. Another benefit is that it helps skin retain moisture but doesn’t add a greasy feel.\n\nIn its role as a binding agent, isostearyl neopentanoate can help hold pressed powder makeup (such as eye shadow, blush, etc.) together without losing the powder-like texture.\n\nIsostearyl neopentanoate is a clear, slightly yellow liquid in raw material form.\n\nThe Cosmetic Ingredient Review Expert Panel 2015 assessment of isostearyl neopentanoate deemed it is safe in the practices of use/concentrations (up to 50%) described in their report. It may be animal-derived or synthetic.
