A closer look

What the research shows

Safety assessment

The assessment examined low systemic toxicity and skin irritation; hexylene glycol caused moderate rabbit skin irritation.

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. Historical report; formulation and concentration affect local irritation.
