Registry functions describe possible formulation roles, not results for a finished product. A dictionary entry is not an approval or a safety assessment.

A closer look

What the research shows

Safety assessment

The panel required formulation to be nonsensitizing and discussed minimizing sensitizing amidoamine impurity contamination.

What this does not tell us

Conditional safety review with impurity and sensitization limitations, not a cleansing efficacy trial or a claim that contact allergy cannot occur.
