How we scored it

Lauric acid (C12H24O2, ~200 Da, coconut) + proline (C5H9NO2, ~115 Da, fermentation) - H2O (18) = 297 Da; all-natural fragments = 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

Made by acylating proline (from protein hydrolysis/fermentation) with lauric acid derived from coconut or palm kernel oil. No significant petrochemical route is used for either building block.

In plain English

A skin- and hair-conditioning ingredient made by combining a coconut-derived fatty acid with the amino acid proline.
