Abstract (en)
A method for producing detergent particles having a bulk density of 650 g/L or more, including the following steps 1 to 3: step 1: mixing powdery raw materials having an oil-absorbing ability of 0.4 mL/g or more; step 2: adding water or an aqueous binder solution to a mixed powder obtained by the step 1, and preparing base particles with a low-shearing granulator; and step 3: mixing the base particles obtained in the step 2, with a surfactant composition containing an anionic surfactant and water. By using a method of the present invention, some effects such as high-density detergent particles generally having very small skin irritability, favorable biodegradability, and a sharp particle size distribution can also be produced in high yields are exhibited. Having a sharper particle size distribution would lead to exhibition of the effects that a detergent having not only improved external appearance but also favorable free flowability and excellent productivity can be efficiently obtained.
