Abstract: The present invention relates to a manufacturing process of a coated granular sodium percarbonate, wherein the surface of said sodium percarbonate establishes a multiple coating layer by being internally coated with a specific composition containing alkali metal silicate while externally coated with a specific composition containing alkali metal sulfate on upper part of said internally coated layer thus providing said sodium percarbonate an excellent dissolving rate in water as well as a good storage stability, preventing it from caking during delivery or storage, and being ultimately utilized as an effective detergent bleach containing zeolite as its detergent builder.

Abstract: The present invention relates to a coated granular sodium percarbonate for detergent and its manufacturing process, and more particularly to a coated granular sodium percarbonate and its manufacturing process, wherein the surface of said sodium percarbonate establishes a multiple coating layer by being internally coated with a specific composition containing alkali metal silicate while externally coated with a specific composition containing alkali metal sulfate on upper part of said internally coated layer thus providing said sodium percarbonate an excellent dissolving rate in water as well as a good storage stability, preventing it from caking during delivery or storage, and being ultimately utilized as an effective detergent bleach containing zeolite as its detergent builder.
