About
A UV filter ester of PABA (para-aminobenzoic acid) restricted under EU Annex II/167 due to photosensitization concerns that led to its removal from sunscreen formulations in many markets.
Glyceryl PABA (glyceryl para-aminobenzoate) is the glyceryl ester of PABA, a UV-B absorbing compound historically used in sunscreens. It is listed in EU Regulation 1223/2009 Annex II/167, indicating it is prohibited from use in cosmetic products. PABA and its esters are associated with photosensitization, contact dermatitis, and stained clothing, which led to their market withdrawal in favor of newer UV filters.

Known concerns
