Benzotriazolyl Dodecyl P-Cresol
Benzotriazolyl Dodecyl P-Cresol (CAS 125304-04-3) is a broadband UV absorber belonging to the benzotriazole chemical family. Its IUPAC name is Phenol, 2-(2H-Benzotriazol-2-Yl)-6-Dodecyl-4-Methyl-, Branched And Linear. It is used primarily to stabilize cosmetic formulations, particularly those in transparent packaging, at a recommended usage rate of 0.01%–0.1%.
Protects sensitive ingredients such as colors, fragrances, and natural extracts from photooxidative degradation. As a broadband UV absorber, it helps maintain product integrity and extends the stability of formulations exposed to light.
Primarily a product-stabilizing UV absorber rather than a leave-on sunscreen active; usage is limited to 0.01%–0.1%. No specific skin contraindications are noted in the source.
