Abstract

In this work, since PLS-1 provided the most accurate predictions, it was applied in the proposed method for determining these colorants in commercial cosmetic products as colognes, facial tonics, deodorants, after shave lotions, bath gels, bath salts and shampoos. In all cases the obtained results are satisfactory.
