• the product of the present invention was found to be excellent in cleaning performance, high temperature and low temperature storage stability. From Comparative Examples 1 and 3 to 5, when the component (a) was not contained, the detergency against oil stains was not sufficient. From Comparative Example 7, when the component (a) was excessively contained, a uniform liquid composition could not be obtained. From Comparative Examples 2 and 6, when the component (a-1) in the component (a) was too small, the detergency was not sufficient. From Example 14 and Comparative Example 12, it was found that when the pH of the composition was 7.5 or more, there was a tendency for the cleaning performance to increase. Further, from Comparative Examples 9 to 11 and 13 to 16, it was found that when polyoxyethylene alkyl ether or alkyl (poly) glycoside was used instead of the component (b), the cleaning performance with respect to the low-modified oil was inferior.
