TOOTH WHITENING COMPOSITION AND METHOD

摘要

A combined preparation is described comprising a first sodium or postassium hydroxide and xylitol aqueous solution, a second hydrogen peroxide aqueous solution and a third aqueous solution containing sodium or potassium hydroxide, a fluoride salt, hydroxyapatite and xylitol. Said preparation can be advantageously used in tooth whitening cosmetic methods without causing the undesired effects generally associated to the use of hydrogen peroxide.
