Is Erucyl Erucate natural?

Yes. Both halves are long-chain fatty compounds from rapeseed/crambe oil; esterification adds no petrochemical mass.

How we scored it

Ester of erucyl alcohol (C22) and erucic acid (C22), both natural oleochemical fatty chains; esterification loses only water. 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 esterifying erucyl alcohol with erucic acid, both derived from high-erucic rapeseed or crambe oil. C22 chains are too long for the economical synthetic (Ziegler) alcohol route, so natural sourcing dominates.

In plain English

A wax-like ester made by combining erucyl alcohol and erucic acid, both long-chain fatty compounds typically from rapeseed or crambe oil. Used as a skin-softening emollient.
