The present invention provides a liquid reducing agent composition and a substrate that can obtain the advantages of reducing the reducing power over time, odor, and reducing sugar with less impact on the human body and the environment, and further obtain good fastness The reduction and cleaning method. In one aspect, a liquid reducing agent composition comprising (A) reducing sugar, (B) amphiphilic component, and water is provided, and the above-mentioned (B) amphiphilic component is selected from (B1) having Aromatic carbon ring polyester resin and (B2) general formula (1): One or more compounds in the group consisting of the indicated compounds. In one aspect, a method for reducing and cleaning a substrate is provided, which includes cleaning the substrate in the presence of (A) reducing sugars and (B) amphiphilic components, the above (B) amphiphilic The component is one or more compounds selected from the group consisting of (B1) a polyester resin having an aromatic carbon ring and (B2) a compound represented by the general formula (1). |
