Abstract: The present invention relates to provide a scrub soap and a method for manufacturing the same. A method for manufacturing a scrub soap includes preparing a scrub agent consisting of a shirasu and a hollow shirasu having a different average particle diameter each other, preparing a fatty acid composition consisting of at least one kind of fatty acid, preparing an alkali aqueous solution by dissolving at least one kind of alkali metal hydroxide of which molar ratio to at least one kind of fatty acid is not more than 1, and preparing a soap basis material by mixing the scrub agent, the alkali aqueous solution and the fatty acid composition.
