How we scored it
Where it comes from
Made by esterifying fermentation-derived citric acid with isopropanol, a petrochemical solvent-grade alcohol. The citrate backbone accounts for slightly more mass than the synthetic ester groups.
In plain English
An emollient ester made from citric acid and isopropyl alcohol. The citric acid portion comes from fermentation, while the isopropyl groups are synthetic, giving a mixed origin.
