Non-oxidative tooth whiteners for dentifrice application

摘要

The present invention relates to a non-oxidative approach for removing or reducing stains, which is based on reactive modification and complexation of porphyrins. This approach was found to be suitable for removing stains from hydroxyapatite, and the whiteness that was achieved using this formulation was found to be superior as compared to the whiteness obtained by using an oxidizing solution containing 3% hydrogen peroxide.
