Title
(EN) FILM COATING COMPOSITION FOR WHITENING TEETH
(FR) COMPOSITION DE PELLICULAGE POUR BLANCHIR LES DENTS
Abstract
(EN)
The invention relates to a film coating composition for whitening teeth, comprising 6-20 % of urea peroxide, 2-9 % of film formers and 77-88 % of highly volatile organic solvents base on the total weight of the composition. The said highly volatile organic solvents are selected from ether, ethylacetate, anhydrous ethanol, acetone etc.; the said film formers are artificial or natural materials such as cellulose, polyvinyl acetal, coumarone indene resin, shellac and the like. The said composition can provide film on dry teeth surface rapidly and a remarkable effect is obtained.
(FR)
L'invention concerne une composition de pelliculage pour blanchirles dents, qui comprend entre 6 et 20 % de peroxyde d'urée, entre 2 et 9 % d'agents filmogènes et entre 77 et 88 % de solvants organiques très volatils, par rapport au poids total de la composition. Lesdits solvants organiques très volatils appartiennent aux groupes suivants: éther, éthylacétate, éthanol anhydre, acétone, etc.. Les agents filmogènes sus-mentionnés sont artificiels ou à base de substances naturelles telles que la cellulose, l'acétal polyvinylique, la résine coumarone-indène, le vernis gomme laque et autres. La composition permet de former rapidement une pellicule à la surface de la dentition sèche et produit un effet remarquable.
