A closer look

What the research shows

Safety assessment

The assessment addresses toxicology of EDTA and its named salts for cosmetic use.

What this does not tell us

Published safety assessment, not an efficacy trial. Its conclusion is limited to the reported cosmetic uses and concentrations, and relies partly on group read-across where individual data are missing. It does not establish current regulatory status or guarantee tolerance for every formulation. No independent skin-benefit trial is established; salt-specific data are limited and group evidence supports the assessment.
