EVALUATION OF THE AVOBENZONE PHOTOSTABILITY IN SOLVENTS USED IN COSMETIC FORMULATIONS

The use of sunscreen products is very important nowadays. The photostability of UV filters incorporated in these products must be preserved during its storing and application processes in order to achieve the claims about photoprotection of the commercial products. The photostability of avobenzone,...
