Definitions
- said particles are flaky shaped, having a thickness of 30 to 50 nm.
- the aforementioned composite particles are deposited into the teeth crevices, thereby replenishing lost enamel and brightening the teeth (whitening). Additional benefits are realized by the slow release of cationic germicide from the deposited composite particles. In particular, this slow release provides prolonged antimicrobial activity and effectively prevents the formation of biofilm.
- the composite particles can be used as an abrasive component in toothpaste in the same way as common abrasives.
- Yet another aspect of the invention relates to a method of preparing composite particles as defined herein, said method comprising the steps of:
