PROBLEM TO BE SOLVED: To obtain a detergent excellent in the long-term storage stability in the form of a powder and capable of preventing the concentration of its aqueous solution from being reduced after preparation of the solution and of preventing the cationic germicide from being degraded by blending sodium percarbonate or sodium perborate, a cationic germicide and a serine-N,N- diacetate salt in specific proportions. SOLUTION: In 100 pts.wt. of sodium percarbonate or sodium perborate (A), are incorporated 0.5-100 pts.wt. of a cationic germicide (B) and 0.05-100 pts.wt. of a serine-N,N-diacetate salt (C) represented by the formula (wherein M is H, Na, K or NH4 ). The component B may include cationic surfactant-base germicides, biguanide-base germicides, and amino acid-base surfactants. In addition, the composition may preferably contain an alkaline inorganic metal salt (D) and further a surfactant, particularly a nonionic surfactant (E). Usually, 10-800 pts.wt. of component D and 0.5-100 pts.wt. of component E are incorporated based on 100 pts.wt. of component A. |
