い。2. Description of the Related Art A concentrated liquid detergent which is diluted with water at the time of use is more economical as the concentration ratio is higher. However, at a high concentration, it can be dispersed and dissolved well in water. It is difficult, and the stock solution often gels.
In addition, even in a homogeneous system, the diluent may become turbid or the viscosity may be significantly reduced (less than 100 mPa · s at 20 ° C.), so that the adhesion to a dish may be reduced or the squeeze type container may be used. Adjustment of the liquid volume becomes difficult, which is not preferable.
