    Abstract: A novel method for purifying a sugar phosphate or its salt, in which a sugar-containing mixture of a sugar phosphate or its salt and phosphoric acid or its salt is subjected to electrodialysis to remove the phosphoric acid or its salt from the mixture.According to this method, the phosphoric acid or its salt can be readily obtained in a reusable form. The method is thus quite advantageous in view of the economy.

    Abstract: A detergent composition containing (A) an amide ether derivative mixture containing at least 50 wt.% in total, based on the solid component, of (1) an amide ether carboxylic acid or a salt thereof and (2) an amide ether in a weight ratio, (1)/(2), of 99:1 to 10:90 and further containing at most 5 wt.% based on the solid component, of a glycerol derivative, and (B) an amphoteric surfactant. In Formulae (1), (2) and (3) R is C5-C23 alkyl, alkenyl or phenyl substituted by C5-C23 alkyl; R is H, -(C2H4O)nCH2COOM, -(C2H4O)mH or C1-C3 alkyl; M is H, alkali metal cation, etc.; n and m are each a number of 1 to 20; R is H, -(C2H4O)mH or C1-C3 alkyl; and R is H, -(C2H4O)nCH2COOM or -(C2H4O)mH. The composition is lowly irritative and highly foaming and gives creamy foams.
