In our research, we investigated the coloring effect of beverages, the decolorizing effect of natural oils and natural sorbents. In addition, we’ve found the coloring effects of selected drinks (red wine,Coca Cola,black tea,coffee). The most coloring was Coca Cola and red wine. Activated charcoal proved to be the most effective bleach, which has shown 182% of bleaching properties of the Colgate whitening toothpaste. After statistic determination of the coloring properties of the substances we formulated whitening blends consisting of a combination of the most effective oils and sorbents. All the bleaching masses which we produced showed a higher bleaching efficacy than conventional whitening toothpaste. The best bleaching mass recorded 188% of bleaching properties of whitening toothpaste.
