The present invention provides an alkaline detergent composition having good detergency, capable of suppressing the formation of colloidal silicate, preventing corrosion of stainless steel, and excellent in defoaming property. The alkaline detergent composition of the present invention comprises an alkali metal hydroxide as the component (A), a chlorinated oxidant as the component (B), an alkali metal silicate as the component (C), and an alkali metal silicate as the component (D). A surfactant is contained, and the amount of effective chlorine and SiO 2 in the component (C) are in a mass ratio such that the value of (effective chlorine amount) / (SiO 2 ) is 0.16 or more and 7.0 or less. It is characterized by containing. [Selection figure] None |
