PURPOSE: To obtain the subject composition for electric washing machine, etc., containing a nonionic surfactant having a specific melting point and HLB, a porous oil absorbing carrier, crystalline aluminosilicate and an inorganic salt having specific solubility, having excellent strength and exhibiting good water soluble properties.
CONSTITUTION: (A) 10-40wt.% nonionic surfactant (e.g. polyoxyethylene alkyl ether) having ≤90°C melting point and 7.5-17.0 HLB is blended with (B) 2-25wt.% porous oil absorbing carrier (e.g. amorphous silica), (C) 20-60wt.% crystalline aluminosilicate (e.g. zeolite) and (D) 1-30wt.% inorganic salt (potassium carbonate) capable of dissolving ≥50wt.% of the inorganic salt during 0.9-3sec when 0.2g of the salt having 425-500μm particle diameter is added to 100ml pure water and, as necessary, polyethylene glycol and polyacrylic acid sodium salt are mixed and the mixture is charged and molded under pressure to provide the objective tablet form detergent composition.
