Is Potassium Ascorbyl Tocopheryl Phosphate natural?

It depends. Value depends on whether the tocopherol used is natural (plant) or synthetic (dl-alpha, petrochemical); the ascorbate, phosphate and potassium fragments are natural either way.

Why the score varies

This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.

Ask your supplier. A batch-specific certificate of origin or bio-based carbon test (ASTM D6866) settles which route applies.

How we scored it

If tocopherol is natural: ascorbate, tocopherol, phosphate and potassium all natural, approx 1.0. If dl-tocopherol: only phosphate/K/ascorbate natural, est. approx 0.4. No formula or CAS supplied.
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

A phosphate ester linking vitamin C and vitamin E with a potassium counter-ion. Vitamin E may be natural plant-derived or synthetic dl-alpha, and bulk vitamin E economics favor synthetic.

In plain English

An antioxidant combining vitamin C and vitamin E linked through a phosphate group, used to protect skin from oxidative stress. Made from vitamin C, vitamin E and mineral phosphate.
