<p><P>PROBLEM TO BE SOLVED: To provide a washing tub cleaner composition which does not contain a surfactant at all, does not use lime as an alkali source, is excellent in washing property, and eco-friendly to a surrounding atmosphere, and to provide its production method. <P>SOLUTION: A mixture composition formed of sodium percarbonate powdery particles not using surfactants and alkali builders and coated with specific components, inorganic powder containing shell-calcined calcium, and a water-soluble binder enhances a washing capacity of a washing tub due to a grinding/exfoliation action to the contamination of the shell-calcined calcium and a proper maintenance action of an alkali degree, thereby reducing an influence to the surrounding atmosphere. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
