Methylparaben
Medium RiskMethylparaben is a preservative in the paraben family. Toxicology datasets generally show low acute toxicity; concerns focus on weak endocrine activity observed in some assays, plus aggregate exposure and limited pregnancy-specific outcome data for topical cosmetic use. The medium-risk signal is endocrine-related uncertainty and conservative pregnancy-focused avoidance rather than a clearly demonstrated pregnancy harm at cosmetic exposure levels.
