Safety Profile
Specific reviews by the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) for Sodium Phenolsulfonate are not available. While data on related compounds like Sodium Naphthalenesulfonate (up to 2% for SNS, 0.1-0.4% for SPNS) suggests safety, this information is not directly applicable. The FDA status for specific cosmetic use of Sodium Phenolsulfonate remains largely unspecified.

Verdict
Despite its demonstrated antimicrobial and deodorant properties and a reported absence of irritation at 0.2% in animal studies, the lack of comprehensive human safety assessments (CIR/SCCS) leads to insufficient data for a definitive recommendation in precision skincare formulations.
