Abstract

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: EQU (R.sub.1)(R.sub.2)N(CX.sub.2).sub.n N(R.sub.3)(R.sub.4) 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; R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are independently selected from the group consisting of hydrogen; alkyl; aryl; alkaryl; arylalk; hydroxyalkyl; polyhydroxyalkyl; polyalkylether having the formula --((CH.sub.2).sub.y O).sub.z R.sub.7 where R.sub.7 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(CH.sub.2).sub.y).sub.z R.sub.7 ; the group --C(O)R.sub.8 where R.sub.8 is alkyl…
