Abstract
The present invention relates to a process for preparing particles for supporting a surfactant, comprising a step of giving a defect to a coating film containing a water-soluble component, wherein the coating film is formed on surfaces of raw material particles; and a process for preparing detergent particles comprising a step of mixing a surfactant composition and the particles for supporting a surfactant obtained by the above process, under conditions that the surfactant composition shows a liquid state. By using the process of the present invention, there can be obtained particles for supporting a surfactant, in which the supporting ability of the particles is improved, without lowering the detergency. In addition, by using the particles for supporting a surfactant, there can be obtained detergent particles having excellent detergency.
