Is Methylpropanediol natural?

No. This branched diol is manufactured from petrochemical aldehydes; no commercial fermentation route exists, unlike its isomer 1,3-propanediol.

How we scored it

2-methyl-1,3-propanediol made via petrochemical isobutyraldehyde/formaldehyde route; whole molecule is synthetic. 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

Produced industrially from petrochemical-derived aldehydes (isobutyraldehyde/formaldehyde route) followed by hydrogenation. Unlike 1,3-propanediol, it has no significant corn-fermentation alternative in commercial use.

In plain English

A synthetic solvent that helps other ingredients dissolve and improves the texture of lotions. Not the same as the corn-derived propanediol sometimes used in natural formulations. Made from petrochemical starting materials.
