A functionalized polyamine comprising the reaction product of (A) a cyano- ornguanidino-containing compound selected from the group consisting of cyanamides or saltsnthereof, dicyanamides or salts thereof, dicyandiamides or salts thereof, guanidines or saltsnthereof, biguanidines or salts thereof, and combinations thereof, and (B) a polyaminenprepared from at least one monomeric amine, wherein the cyano- or guanidino-functionalngroups are attached to the polyamine or incorporated therein to form the functionalizednpolyamine, provided that the monomeric amine and the cyano- or guanidino-containingncompound are present in the functionalized polyamine in a molar ratio of from 1.1:1 ton100:1, respectively. The functionalized polyamines are especially useful as anti-dyentransfer and color protection agents in laundry detergent compositions. |
