How we scored it
Whole phytosterol molecule extracted unchanged from vegetable oil = 1.00
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
Extracted and purified from soybean oil deodoriser distillate or pine tall oil. No commercially significant petrochemical synthesis route exists.
In plain English
A plant-derived, fat-like compound (a phytosterol) found in soybean and pine oils. It helps stabilise creams and lotions and leaves skin feeling conditioned. It's used just as extracted and purified from vegetable oil, without further chemical modification.
