(57) Abstract: A detergent raw material containing a nonionic activator as a main base by blending a nonionic activator and / or an aqueous solution of a nonionic activator and an acid precursor into a builder and / or a porous oil absorption carrier. By the step of preparing a mixture and the step of heating the mixture of the resulting detergent raw materials to granulate while increasing the bulk density while rolling to prepare a granulated product, the bulk density is 0.6 to A method for producing nonionic detergent particles, characterized in that 1.2 g / ml of nonionic detergent particles are obtained. [Effect] By using the method for producing nonionic detergent particles according to the present invention, the composition is not limited to a specific substance, the degree of freedom of composition is high, the bulk density is high, and the content of the nonionic activator is high. It has become possible to obtain nonionic detergent particles which are excellent in flowability and non-caking property of powder and which are free from stains. |
