Abstract
The present invention relates to fabric care compositions having enhanced fabric color protection, said compositions comprising a bleach scavenging system comprising: i) one or more organic sulfur compounds having the formula: R—S—R or R—S—S—R wherein each R is independently hydrogen, C2-C20 linear or branched, substituted or unsubstituted alkyl; provided at least one R unit is not hydrogen; ii) one or more inorganic sulfur compounds selected from the group consisting of the sodium, potassium, lithium, calcium, and magnesium salts of metabisulfite, thiosulfate, sulfite, bisulfite, and mixtures thereof; and iii) and mixtures thereof.
