How we scored it

2,2,4-trimethylpentane-1,3-diol (from petrochemical isobutyraldehyde) diesterified with isobutyric acid (also isobutyraldehyde-derived) -> 0/286.41 = 0.0
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

Trimethyl pentanyl diisobutyrate (TXIB) is manufactured entirely from petrochemical isobutyraldehyde via aldol condensation and esterification. No natural production route is used commercially.

In plain English

A fully synthetic diester (TXIB) made from petrochemical isobutyraldehyde. Functions purely as a plasticiser, keeping films, nail polish and some packaging materials flexible; it has no botanical or mineral origin.
