A method for producing detergent particles including the steps of spray-drying a slurry containing an anionic surfactant and increasing bulk density of the resulting particles with a high-speed mixer, wherein a mixing treatment is carried out at a given breaking load at 25°C and at a given degree of particle growth, i.e. an average particle size after a treatment of increasing a bulk density / an average particle size before a treatment of increasing a bulk density, wherein an extent of an increase in the bulk density before and after the treatment of increasing a bulk density is from 20 to 800 g/L. |
