FIELD: chemical industry.

SUBSTANCE: present invention relates to a solid detergent composition for laundering made of free-flowing particles comprising: (a) 0.1 to 5 wt. % of the coloring agent particle, containing: (i) 2 to 10 wt. % of the coloring agent, the coloring agent having the following structure:

where the values of the indices x and y are independently selected from values from 1 to 10; and (ii) 60 to 98 wt. % of clay; and (b) from 0.5 to 20 wt. % of an AES particle containing: (i) 40 to 60 wt. % of a partially ethoxylated alkyl sulfate anionic detersive surfactant, wherein the partially ethoxylated alkyl sulfate anionic detersive surfactant has an average molar degree of ethoxylation of from 0.8 to 1.2, and wherein the partially ethoxylated alkyl sulfate anionic detersive surfactant is characterized by the following molar distribution of ethoxylation: (ii) 40 to 50 wt. % is not ethoxylated, has an ethoxylation degree of 0; (i.ii) from 20 to 30 wt. % has an ethoxylation degree of 1; (i.iii) from 20 to 40 wt. % has an ethoxylation degree of 2 or higher; (ii) 20 to 50 wt. % salt, the salt being selected from sodium sulfate and/or sodium carbonate; and (iii) 10 to 30 wt. % of silica.

EFFECT: technical result is to minimize the undesirable consequences of excessive staining.
