Is Bishydroxyethyl Biscetyl Malonamide natural?

Mostly. Cetyl chains come from palm or coconut-derived cetyl alcohol; malonic acid, the amine nitrogen (ammonia) and the hydroxyethyl groups (ethylene oxide) are petrochemical.

How we scored it

2 cetyl C16H33 = 450.9 natural; malonyl C3H2O2 70.0 + 2 N 28.0 + 2 hydroxyethyl C2H5O 90.1 = 188.2 petrochemical; total 639.1; 450.9/639.1 = 0.71.
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

Dominant route: N-hexadecyl ethanolamine (cetyl chain from vegetable oil, nitrogen and hydroxyethyl group from petrochemical ethanolamine) condensed with malonic acid or dimethyl malonate. Supplier note: Ziegler-derived cetyl chains would lower the value.

In plain English

A waxy, ceramide-like conditioning ingredient used for hair and skin. It carries two cetyl (C16) fatty chains from vegetable oil on a malonic acid core with hydroxyethyl groups; the core and hydroxyethyl parts are petrochemical.
