FIELD: chemistry. ^ SUBSTANCE: invention relates to laundry detergents. The solid detergent composition in form of particles contains a detergent anionic surfactant, a solid carrier with total pore volume greater than 0.3 ml/g, average pore diametre greater than 3 micrometres and surface area less than 1.0 m2/g, a zeolite additive, a phosphate additive and a silicate salt. At least part of the detergent anionic surfactant and at least part of the solid carrier are in form of a jointly ground additive. All components are taken in a defined ratio. The method involves mixing the initial material to make a solid carrier with formation of an aqueous mixture, drying the aqueous mixture at input gas temperature of at least 300C for less than 20 seconds to form solid carrier material and mixing the solid carrier material with a detergent anionic surfactant to form a jointly ground mixture. The solid carrier material or jointly ground mixture is mixed with one or more components selected from a zeolite additive, a phosphate additive and a silicate salt. ^ EFFECT: invention enables to obtain solid unfinished laundry detergent compositions which contain a combination of a detergent anionic surfactant and a high-porosity carrier. ^ 7 cl, 1 tbl |
