| 摘要 |
THE PRESENT INVENTION PROVIDES A HIGH-BULK-DENSITY GRANULAR MATERIAL WHICH COMPRISES CORE PARTICLES CONTAINING A SURFACTANT AND/OR DETERGENT BUILDER AND A COATING SUBSTANCE THEREON IN POWDER FORM WHICH IS AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF SALTS OF ORGANIC ACID OR INORGANIC ACID (WITH CATION BEING POTASSIUM ION, MAGNESIUM ION, OR CALCIUM ION) HAVING A SOLUBILITY NO LESS THAN 1 G IN 100 G OF WATER AT SOC AND A DETERGENT COMPOSITION CONTAINING THE HIGH-BULK-DENSITY COATED PARTICLE DEFINED ABOVE. ACCORDING TO THE PRESENT INVENTION, IT IS POSSIBLE TO OBTAIN, BY SIMPLE COATING PROCESS, COATED PARTICLES WITH IMPROVED SOLUBILITY WHILE KEEPING THE GOOD MANUFACTURING PROPERTIES AND POWDER PROPERTIES. THE COATED PARTICLES OF THE PRESENT INVENTION ARE USEFUL AS DETERGENT PARTICLES AND BUILDER PARTICLES TO BE USED AS A RAW MATERIAL OF HIGH-BULK-DENSITY GRANULAR DETERGENT COMPOSITION.
