PEROXIDISED POLYORGANOSILOXANES (POS), ONE OF THE METHODS FOR PREPARING THEM AND THEIR USES AS BLEACHING AGENT IN DENTAL COMPOSITIONS

摘要

The invention concerns polyorganosiloxanes (POS) grafted with peroxide functions and functions stabilising the latter. Said stabilised peroxidised POS are designed to form a novel oxidising system useful as bleaching agents, for example or dental or detergent compositions. The invention aims at and succeeds in providing peroxygenated bleaching agents more stable and more efficient than those known in prior art. The inventive stabilised and peroxidised POS correspond for example to the formula (a). The invention also concerns a method for making said peroxidised POS, the precursors thereof and their uses as bleaching agents in dental compositions (toothpaste or detergent compositions).
