FIELD: chemistry.

SUBSTANCE: group of inventions relates to a composition in the form of a tooth whitening agent, a method for preparing and using the same. Disclosed composition is a single-phase composition and contains: acceptable for use in the oral cavity carrier medium, where the carrier medium acceptable for oral use is anhydrous and contains polyethylene glycol, propylene glycol, glycerine or combinations thereof, and contains a bleaching agent, where the bleaching agent is an oxidising agent, and a dye encapsulated by a protective barrier which is a biodegradable polymer selected from a group consisting of polylactic acid (PLA), polyhydroxyalkanoate (PHA), polyglycolide (PGA), polycaprolactone (PCL), polysaccharide and combinations thereof. Protective barrier suppresses movement of the dye in a carrier medium acceptable for oral cavity for a period of time of at least 1 day. Method of producing the above composition in the form of a tooth whitening agent involves: (a) mixing the bleaching agent with a carrier medium acceptable for oral use to form a mixture; (b) dispersing a dye encapsulated by a protective barrier in a mixture formed at step (a) to form a composition in the form of a tooth whitening agent. Also disclosed is a method for teeth surface whitening, which involves contacting the dental surface with the above composition in the form of a tooth whitening agent.

EFFECT: composition of the composition provides its stability and suppression of movement of the dye in a carrier medium acceptable for oral cavity for a period of time of at least 1 day.
