FIELD: chemistry.SUBSTANCE: composition of preparation for teeth cleaning contains effective quantity of arginine in free form or in form of salt; abrasive substance, containing (i) natural sodium carbonate (NSC) with the average size of particles 3-7 mcm and moisture absorption 12-25 g/100 g and (ii) precipitated calcium carbonate (PCC) with the average particle size 1-5 mcm and water absorption higher than 25 g/100 g. Ratio of natural calcium carbonate to precipitated calcium carbonate constitutes from 1:2 to 1:3. Composition has pellicle cleaning ratio (PCR), at least, 70 and value of abrasivity of isotope-labelled dentin (RDA) lower than 140. Method of oral cavity care includes application of effective quantity of said composition in oral cavity of individual requiring it.EFFECT: effective teeth cleaning and strengthening without injuring abrasive action, which makes it possible to apply it, in particular, for individuals with increased teeth sensitivity.13 cl, 2 tbl, 2 ex |
