About

Caprylyl Butyrate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Caprylyl Butyrate is a fatty acid ester used as a fragrance ingredient and emollient in cosmetic formulations, providing a fruity, pineapple-like odor profile. It is not listed in EU Annex II or III restrictions of Regulation (EC) No 1223/2009. Like many fragrance esters, it has a low molecular weight that can occasionally act as a respiratory sensitizer in aerosolized products, which is reflected in its score being at the lower end of the safe range.
