COLOR STABLE PEROXIDE CONTAINING DENTIFRICE FORMULATIONS WITH DYE ENCAPSULATED SILICA SHELL NANOPARTICLES |
摘要 |
A composition for minimizing color fading of an oral care composition is provided. The composition comprises: a) an organic dye-encapsulated silica shell nanoparticle matrix, b) a physiologically stable fluoride ion providing compound in an amount of about 0.1% to about 1% by weight, c) a peroxide species providing compound in an amount of about 1% to to about 20% by weight. The encapsulated silica shell dye nanoparticle stabilizes the color against degradation in the presence of peroxide and fluoride ions. |
