What the research shows

Safety assessment

The panel accepted the described uses when formulated to be nonirritating.

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. Some tests concern mixtures or partly characterized technical material; conclusions are limited to the assessed cosmetic conditions.
