A closer look

What the research shows

Safety assessment

The assessment evaluated toxicity, irritation and sensitization in the described cosmetic settings.

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 evidence and mixed polysorbate data; parenteral drug safety and topical cosmetic exposure are distinct.
