How we scored this
The concern value reflects this ingredient's chemical identity — its hazard profile from the published classifications and regulatory status below — not the safety of a product it appears in. A score near 40 is the baseline for ingredients with no specific signal (water scores 40 by design), so a mid-range value is not a safety verdict.
Concern score 70/100 (high) · high confidence.
