PROBLEM TO BE SOLVED: To obtain the subject detergent composition with bulk density within a specific range, excellent in biodegradability and safety and further improved in detergency, comprising a anionic surfactant and a specific amine oxide-type surfactant in specified proportions. SOLUTION: This detergent composition with a bulk density of 0.5-1.2g/mL is obtained by blending (A) 15-50wt.% of an anionic surfactant (e.g. higher fatty acid salt) with (B) 1.0-20wt.% of an amine oxide-type surfactant of formula I (R1 is a 10-20C alkyl or alkenyl; R2 and R3 are each 1-3C alkyl, alkeneyl or H; (n) is a number of 0-8) in the weight ratio B/A of (1:100) to (100: 100) followed by 1-60wt.% of an aliminosilicate and 1-40wt.% of a crystalline silicate of formula II (M is a group I a element; Me is at least one kind selected from groups IIa, IIb, IIIa, IVa and VIII elements; y/x=0.5-2.6; z/x=0.01-1.0; (w) =0-20; n/m=-0.5-2.0) and then drying, grinding and granulation. |
