Is Triphenyl Phosphate natural?

Mostly not. A plasticiser whose phosphate core is mineral-derived while its three phenyl rings are petrochemical.

INCI nameTriphenyl Phosphate
CAS115-86-6
FormulaC18H15O4P · 326.3 Da
FunctionPlasticiser
FeedstockPhosphorus oxychloride (mineral phosphorus) esterified with petrochemical phenol.

How we scored it

Triphenyl phosphate C18H15O4P 326.3 Da: the phosphate group PO4 95.0 Da counts as natural mineral origin (as in Tricresyl Phosphate); the three phenyl groups 231.3 Da come from petrochemical phenol. 95.0/326.3 = 0.29.
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

Phosphorus oxychloride (mineral phosphorus) esterified with petrochemical phenol.

In plain English

A plasticiser made by combining phosphorus with three synthetic phenol molecules. A fully man-made industrial chemical, not naturally occurring.
