PROBLEM TO BE SOLVED: To obtain a functionated polyamine especially useful as a dye transfer- preventing agent and a coloration-preventing agent in detergent compositions for washing. SOLUTION: This functionated polyamine contains a polyamine reaction product produced from (A) a cyano or guanidino-containing compound selected from the group consisting of cyanamides or their salts, dicyanamides or their salts, dicyandiamides or their salts, guanidines or their salts, biguanidines or their salts and their combinations and (B) at least one monomer amine, provided that the monomer amine and the cyano or guanidino-containing compound exist in a molar ratio of 1.1:1 to 100:1 in the functionated polyamine. The cyano or guanidino functional groups are bound to or incorporated in the polyamine to form the functionated polyamine.
