The present invention relates to dryer-activated laundry additive compositions and products having a color care agent and to methods for using the compositions and products. The dryer-activated 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 hydrogen; 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, polyalkylether, carboxylic acid, dicarboxylic acid, phosphonic acid and alkyl phosphonic acid as defined in R1, R2, R3, and R4; linear or branched carboxylic acid and water soluble salts thereof having the general formula -(CHp(R7)q)t wherein t is an integer from 1 to 5, p+q=2; dicarboxylic acid and water soluble salts thereof; linear, branched or polyfunctional substituted branched alkyldicarboxylic acids and water soluble salts thereof; phosphonic acids and water soluble salts thereof, linear, branched or polyfinctional substituted branched alkylphosponic acids and water soluble salts thereof; and 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, polyalkoxy, carboxylic acid, dicarboxylic acid, phosphonic acid and alkyl phosphonic acid 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, a cyclodextrin, or a perfume. Products according to the invention involved the color care composition described above disposed on a substrate such as a sheet. |
