FIELD: production of detergent compositions by granulation process.
SUBSTANCE: proposed method includes first stage (i) of mixing solid component and first liquid binder in mechanical granulator; liquid binder contains anion-active surfactant and nonionogenous surfactant and/or soap and/or fatty acid, thus obtaining powder; proposed method includes stage (ii) of mixing the powder obtained at stage (i) and second liquid binder in granulator at low rate of powder shift; second liquid binder contains liquid nonionogenous surfactant, soap and/or fatty acid and non-soap anion-active surfactant if necessary, thus obtaining detergent granules. Composition of second liquid binder differs from that of first liquid binder and mass ratio of first liquid binder to the second one ranges from 15:1 to 1:1.
EFFECT: improved quality of powder due to balance between quick dissolvability and quick dispersibility.
