How it affects the score

How to read it on the label

Check whether it sits in the top third of the ingredient list — near the tail means low concentration and limited effect.

Ingredients are listed by descending concentration. Anything after the ~1% anchors (EDTA, hexanediol, preservatives) is effectively trace.
