Stability passing sodium carbonate and its production manner and stability containing passing sodium carbonate, becomes the bleaching cleaning agent composition

摘要

PURPOSE: To obtain sodium percarbonate excellent in stability when mixed in a bleaching agent composition and a detergent composition and especially in a detergent composition contg. zeolite. ;CONSTITUTION: A coating agent selected from a group A consisting of a metaboric acid, orthoboric acid and tetraboric acid and a coating agent selected from a group B consisting of a carbonate, a bicarbonate, sulfate and silicate are used as the coating agent of sodium percarbonate. At least one kind of coating agent selected from the groups A and B as a water-soluble slurry coating agent is used to coat the surface of sodium percarbonate, and stable sodium percarbonate is produced. A bleach detergent composition contg. a powdered detergent composition contg. a surfactant as the essential component and contg. the stable sodium percarbonate thus produced is also produced.;COPYRIGHT: (C)1995,JPO
