<p>The present invention is a powder cleaning agent composition containing (a) an anionic surfactant, (b) a carboxylic acid whereof the primary acid dissociation constant is between 1 and 5 inclusive, the maximum acid dissociation constant is 7 or lower, and the molecular weight is between 46 and 5,000 inclusive, and (c) one or more species of compounds chosen from among inorganic sulfates and inorganic halogenated compounds, each in a predetermined range. The powder cleaning agent composition has a content of 10% or less by mass in inorganic carbonate whereof the solubility is 0.1 g or greater in 100 g of water at 20°C. The powder cleaning agent composition contains, in a specific mass ratio and serving as (a), a specific alkyl sulfate ester salt and one or more species chosen from among specific polyoxyethylene alkyl sulfate ester salts and specific alkyl benzene sulfonates. The (a)/(b) ratio by mass is between 1 and 40 inclusive. The powder cleaning agent composition has a total content of 4% by mass or less in predetermined protease granulated material and predetermined cellulase granulated material. When the powder cleaning agent composition is diluted 300-fold in water at 20°C, the pH is between 2.5 and 6.5 inclusive.</p> |
