FIELD: medicine, pharmaceutics.
SUBSTANCE: invention refers to abrasive materials characterised by the mid-range purification level, and a based dental care product. A prepared in situ composition of precipitated silicon dioxide and silicon dioxide gel contains 10 to 60 vol. % of silicon gel, has linseed oil absorption power within the range more than 100 to 150 ml/100g and has 10% Einlener's abrasivity with respect to brass within the range approximately 2.5 to 12 mg of loss/100000 revolutions. The prepared in situ composition of precipitated silicon dioxide and silicon dioxide gel containing 10 to 60 vol. % of silicon gel when introduced into the dental care product as a unique abrasive component can provide the ratio PCR:RDA 0.7 to 1.1, PCR 90 to 110 and RDA level 95 to 150.
EFFECT: compositions of simultaneously prepared in situ of precipitated silicon dioxide and silicon dioxide gel when used in the dental care product provide relatively high purification at the reduced abrasivity.
