About 4-Aminobenzoic acid and its esters, with the free amino group
PABA and its esters are UV filters and sun protectants but are restricted in the EU due to sensitization and photosensitization potential.
Detailed Analysis
4-Aminobenzoic acid (PABA) and its esters with free amino groups are subject to EU Regulation 1223/2009 restrictions. The restriction language referencing Annex II (banned substances) indicates this ingredient may fall under entry 323 or similar provisions related to para-substituted aromatic amines. The restriction on substances or mixtures at ≥0.1% and the propellant aerosol ban suggest significant regulatory concern. PABA is a known photosensitizer, and its use in cosmetic products is restricted primarily due to sensitization risk and potential for allergic contact dermatitis.
Known Concerns
- ⚠ EU Annex II restriction applies (substances with free amino group at ≥0.1%)
- ⚠ Photosensitization and sensitization potential
- ⚠ Aerosol propellant use explicitly prohibited
