Abstract
The method for producing a fine solid builder particle includes the steps of suspending a solid builder in a dispersion medium containing 20 to 100% by weight of a surfactant, and carrying out wet grinding of the solid builder. The builder composition containing the fine solid builder particle is obtainable by the above method. The detergent composition containing the fine solid builder particle is obtainable by the method. The method for producing a detergent composition includes the steps of carrying out wet grinding of a solid builder using a dispersion medium containing a surfactant to give a mixture of a fine solid builder particle and the surfactant, and further adding the mixture to a composition for a detergent.
