Is 4-Amino-m-Cresol natural? NOI 0.00

Q: Is 4-Amino-m-Cresol natural?

4-Amino-m-Cresol has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. The whole molecule is a synthetic aromatic amine derived from petrochemical phenol/cresol chemistry, with no natural-origin component. An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Substituted aminophenol built from petrochemical aromatic feedstock (cresol/toluidine chemistry); no natural fragment present. 0/123 = 0.0.

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

4-Amino-m-cresol is synthesised from petrochemical aromatic intermediates for use as a hair-dye coupler. No natural production route exists for this synthetic dye intermediate.

In plain English

A synthetic dye-building ingredient used in permanent hair colour to help form colour molecules inside the hair shaft. It's manufactured from petrochemical aromatic compounds, not sourced from plants or minerals.
