How we scored it
Kojic acid (fermentation product) esterified with 2x palmitic acid (oleochemical) — ester of two natural building blocks = 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Kojic acid is produced by fermenting rice, sugars or other carbohydrates with Aspergillus fungi, then esterified with palmitic acid from vegetable oil. Both feedstocks are natural.
In plain English
An ester made from kojic acid (produced by fermenting rice or other starches) and palmitic acid (a fatty acid from vegetable oil). Used as a skin-softening emollient in creams and lotions.
Structure
(5-hexadecanoyloxy-4-oxopyran-2-yl) hexadecanoate
