Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A UV filter and stabilizer with nanomaterial considerations, restricted to maximum 10% concentration in EU cosmetics.
1,3,5-Triazine, 2,4,6-tris(1,1'-biphenyl)-4-yl- (CAS 31274-51-8) is a triazine derivative used as a UV absorber and light stabilizer in cosmetic formulations. CosIng lists a maximum concentration of 10%. GHS hazard statement H413 indicates it may be harmful to aquatic life with long-lasting effects. The substance includes nanomaterial consideration in its CosIng description, which triggers additional safety assessment requirements under EU Regulation 1223/2009. Nanomaterials in cosmetics require specific notification and safety data. The compound has been evaluated for dermal absorption and is considered safe at concentrations up to 10% for non-nanoscale forms. Skin sensitization data is limited.
