Is Ethanolamine Thioglycolate natural?

No. Both ethanolamine and thioglycolic acid are manufactured from petrochemical ethylene oxide, ammonia and chloroacetate feedstocks.

How we scored it

Salt of ethanolamine (ethylene oxide + ammonia) and thioglycolic acid (from chloroacetate); both fragments petrochemical. 0/153 = 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

Ethanolamine is made from ethylene oxide and ammonia; thioglycolic acid is made from chloroacetic acid and sodium hydrosulfide. The two petrochemical building blocks are then combined as a salt.

In plain English

A reducing ingredient used in hair-waving and depilatory products to break down the hair's internal structure. Both its building blocks, ethanolamine and thioglycolic acid, are made from petrochemical feedstocks.
