How we scored it
RNA is a natural biopolymer (typically yeast-derived) with a sodium counter-ion; both fragments natural origin → 1.0.
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
Typically obtained by extracting ribonucleic acid from yeast (e.g. torula yeast) biomass and neutralising with sodium. No formula, CAS or supplier detail was given for this item.
In plain English
The sodium salt of RNA, a natural genetic material typically obtained from yeast. Used as a skin-conditioning ingredient in creams and serums.
