PROBLEM TO BE SOLVED: To obtain a denture cleaning agent having excellent cleaning power on contaminated denture, especially denture stained with tea incrustation, etc., effective for preventing the discoloration and corrosion of the metallic part of the denture and having high storage stability. SOLUTION: This denture cleaning agent free from organic acid or its salt as a foaming component is produced by compounding (A) potassium hydrogen monopersulfate and (B) sodium perborate as oxygen-type bleaching components at a weight ratio A/B of 1/(4.1-10) and a total amount (A+B) of >=45wt.% and further 5-30wt.% (based on the total agent) of an inorganic condensed phosphoric acid salt and adjusting the pH of 1wt.% aqueous solution to 8-11. The denture cleaning agent is incorporated with a granular anionic surfactant having an average particle diameter of 0.05-2mm. |
