Is Ethyl Hydroxymethyl Oleyl Oxazoline natural?

Mostly. The heptadecenyl chain and C2 ring carbon come from vegetable-oil oleic acid; the rest of the ring comes from 2-amino-2-ethyl-1,3-propanediol, made from petrochemical nitropropane and formaldehyde.

How we scored it

Oleic-derived heptadecenyl plus ring carbon C18H33 249.5 natural; rest of ring (N, O, C4, C5, ethyl, hydroxymethyl; C5H10NO2 116.1) petrochemical; total C23H43NO2 365.6; 249.5/365.6 = 0.68.
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: oleic acid from vegetable oils condensed with 2-amino-2-ethyl-1,3-propanediol and cyclised with loss of water. Alternative: none significant.

In plain English

An anti-static hair-conditioning ingredient made from oleic acid (a vegetable-oil fatty acid) joined to a small amino alcohol ring structure, an oxazoline. The amino alcohol part comes from petrochemical nitropropane and formaldehyde.
