FIELD: chemistry.

SUBSTANCE: invention relates to a solid detergent composition for laundry made of free-flowing particles comprising: (a) 0.5 to 20 wt % of an AES particle comprising: (i) 40 to 60 wt % of a partially ethoxylated alkyl sulfate anionic detergent surfactant. The partially ethoxylated alkyl sulfate anionic detergent surfactant has an average molar degree of ethoxylation of 0.8 to 1.2. The partially ethoxylated alkyl sulfate anionic detergent surfactant is characterized by the following molar distribution of ethoxylation: (i.i) 40 to 50 wt % is not ethoxylated, has an ethoxylation degree of 0; (i.ii) 20 to 30 wt % has an ethoxylation degree of 1; (i.iii) 20 to 40 wt % has an ethoxylation degree of 2 or higher; (ii) 20 to 50 wt% of salt. The salt is selected from sulfate salt and/or carbonate salt; and (iii) 10 to 30 wt % of silica; and (b) 0.01 to 2 wt % of an aromatic substance. The aromatic substance contains at least 60 wt % of aromatic materials with ClogP 3.0 or higher.

EFFECT: improved compound properties.
