Is Caprylhydroxamic Acid natural?

Mostly. Coconut or palm-kernel-derived caprylic acid condensed with synthetic hydroxylamine; the fatty-acid portion dominates the molecule's mass.

INCI nameCaprylhydroxamic Acid
CAS7377-03-9
FormulaC8H17NO2 · 159.23 Da
FunctionChelating
FeedstockMade by reacting caprylic acid, a C8 fatty…

How we scored it

Caprylic-acid acyl group C8H15O = 127 Da (natural, coconut/palm-kernel oil) + N-OH fragment = 32 Da (petrochemical hydroxylamine) = 159 Da total; 127/159=0.80.
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.

How it’s made

Methoxide-catalysed reaction of methyl caprylate with hydroxylamine (N-acylation). Each curved arrow moves one electron pair, and the film ends on the score above.

Where it comes from

Made by reacting caprylic acid, a C8 fatty acid from coconut or palm kernel oil, with hydroxylamine, a synthetic nitrogen compound typically derived from ammonia. The fatty-acid chain supplies most of the molecule's mass.

In plain English

Made by combining a coconut- or palm-kernel-derived fatty acid with a lab-made nitrogen compound. Binds trace metals to help keep a formula stable.
