Abstract To increase the washing efficiency and more completely remove stained impurities, chemical bleaches are introduced into the composition of SD (synthetic detergents), the most common of which are peroxide salts - sodium peroxocarbonate (percarbonate) and sodium peroxoborate (perborate).The theoretical substantiation of the process of interaction of sodium carbonate and hydrogen peroxide in the three-component reciprocal system Na 2 CO 3 -H 2 O 2 -H 2 O by the visual-polythermal and isothermal method at 10 and 30°C is carried out. The formation of new compounds of the compositions: Na 2 CO 3 •1,5H 2 O 2 , Na 2 CO 3 •H 2 O•2H 2 O 2 and Na 2 CO 3 •2H 2 O 2 was established, for which the concentration limits of existence were determined. New compounds are identified by chemical and physico-chemical analysis methods.
