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 % by weight of the composition of a color care agent having the formula: (R1)(R2)N(CX2)n N(R3)(R4), wherein X is selected from the group consisting of hydrogen, linear or branched; substituted or unsubstituted alkyl having from 1-10 carbon 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)y O)2R7, 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)z R7; 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.
L'invention porte sur des compositions additives à lessive ajoutées au rinçage, comprenant un agent de protection des couleurs et sur des procédés d'utilisation desdites compositions. Ladite composition additive à lessive comprend environ 0,1 à environ 50 % en poids de la composition, d'agent de protection des couleurs de formule: (R1)(R2)N(CX2)nN(R3)(R4), dans laquelle X est choisi dans le groupe constitué d'hydrogène, linéaire ou ramifié; d'alkyle substitué ou non, ayant 1 à 10 atomes de carbone et d'aryle substitué ou non ayant au moins 6 atomes de carbone; n vaut 1 à 6; R1, R2, R3 et R4 sont choisis séparément dans le groupe constitué d'alkyle, aryle, alkaryle, arylalk, hydroxyalkyle, polyhydroxyalkyle, polyalkyléther de formule: -((CH2)yO)zR7, où R7 représente hydrogène ou une chaîne alkyle linéaire, ramifiée, substituée ou non, à 1 à 10 atomes de carbone et où y est un entier de 2 à 10, z un entier de 1 à 30; alcoxy; polyalcoxy de formule: -(O(CH2)y)zR7; le groupe -C(O)R8 où R8 représente alkyle; alkaryle, arylalk; hydroxyalkyle; polyhydroxyalkyle et polyalkyléther selon la définition dans R1, R2, R3 et R4; CX2CX2N(R5)(R6), au plus un parmi R1, R2, R3 et R4 étant CX2CX2N(R5)(R6), R5 et R6 représentant alkyle; alkaryle; arylalk; hydroxyalkyle; polyhydroxyalkyle, polyalkyléther, alcoxy et polyalcoxy conformément à la définition dans R1, R2 R3 et R4; et soit R1 + R3 ou R4 ou R2 + R3 ou R4 peuvent se combiner pour former un substituant cyclique. Les ingrédients éventuels peuvent être, entre autres, un composé adoucisseur de tissus, à l'ammonium quaternaire.
