How we scored it

C18-C36 fatty acid blend (natural, oleochemical; dimer acids formed by joining natural fatty-acid carbons only) = 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

A mixture of long-chain fatty acids, including dimer acids formed by joining natural C18 vegetable-oil fatty acids. No outside feedstock is introduced during dimerisation.

In plain English
