The present invention relates to rinse-added laundry additive compositions having a color care agent and to methods for using the compositions. The laundry additive composition comprises from about 0.1% to about 50% of by weight of the composition of a color care agent having the formula:(R1)(R2)N(CX2)nN(R3)(R4)wherein X is selected from the group consisting of hydrogen, linear or branched; substituted or unsubstituted alkyl having from 1-10 carbons atoms and substituted or unsubstituted aryl having at least 6 carbon atoms; n is an integer from 1 to 6; R1, R2, R3, and R4 are independently selected from the group consisting of alkyl; aryl; alkaryl; arylalk; hydroxyalkyl; polyhydroxyalkyl; polyalkylether having the formula -((CH2)yO)zR7 where R7 is hydrogen or a linear, branched, substituted or unsubstituted alkyl chain having from 1 to 10 carbon atoms and where y is an integer from 2 to 10 and z is an integer from 1 to 30; alkoxy; polyalkoxy having the formula: -(O(CH2)y)zR7; the group -C(O)R8 where R8 is alkyl; alkaryl; arylalk; hydroxyalkyl; polyhydroxyalkyl, and polyalkylether as defined in R1, R2, R3, and R4; CX2CX2N(R5)(R6) with no more than one of R1, R2, R3, and R4 being CX2CX2N(R5)(R6) and wherein R5 and R6 are alkyl; alkaryl; arylalk; hydroxyalkyl; polyhydroxyalkyl, polyalkylether, alkoxy and polyalkoxy as defined in R1, R2, R3, and R4; and either of R1+R3 or R4 or R2+R3 or R4 can combine to form a cyclic substituent. Optional ingredients include a quaternary ammonium fabric softening compound. |
