FIELD: medicine, pharmaceutics.
SUBSTANCE: group of inventions refers to dental whitening compositions in the form of a liquid crystal or micro-emulsion and methods for using them. The composition contains a dental whitening agent in the amount wherein it is effective for dental whitening, a hydrophilic phase containing water, a hydrophobic phase containing oil, a surfactant specified in a group consisting of anionic, nonionic, amphoteric and zwitterionic surfactants, and a water-soluble co-solvent having a Hildebrand solubility parameter more than 12 (cal/cm3)1/2; the composition contains no thickening agent specified in a group consisting of synthetic resin, natural resin and synthetic resin. The formulation of the composition provides its physical and chemical stability, and also the effectiveness of dental whitening.
EFFECT: method for dental whitening involves applying the above liquid crystal or micro-emulsion composition onto the teeth for a period of time and under conditions effective for dental whitening.
