PURPOSE: To obtain a water-based detergent to be used at specific concentrations and temperatures, capable of effectively cleansing stains de to printing inks or coating materials, free from offensive order and danger of inflammation and explosion, and easy to be disposed, containing a nonionic surfactant with cloud point and an anionic surfactant. CONSTITUTION: This water-based detergent contains (A) a nonionic surfactant with a cloud point of e.g. <=60 deg.C such as a polyoxyalkylene alkyl ether and (B) an anionic surfactant in the weight ratio A/B of e.g. (1:1) to (1:0.3). This detergent is used at a concentration of >=0.2 (esp. 0.6-1.5)wt.% of the total of the components A and B in a cleansing water and at temperatures not lower than the cloud point of the component A. |
