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— 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.
Claims7
A fabric care composition comprising:
- a) from 0.01% by weight, of a bleach scavenging system, said system comprising at least one compound from (i) or (ii):
- i) one or more organic sulfur compounds selected from the group consisting of cystamine, cysteine, cysteine dimethyl ester, cystine, cystine dimethyl ester, 3,3′-thiodipropionic acid, methionine, and mixtures thereof;
- or
- 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;
- b) from about 0.001% to about 90% by weight of a dye fixing agent;
- c) optionally about 0.005% to about 1% by weight, of one or more crystal growth inhibitors;
- d) from about 0.01% to about 20% by weight, of a fabric abrasion reducing polymer;
- e) optionally from about 1% to about 12% by weight, of one or more liquid carriers;
- f) optionally from about 0.001% to about 1% by weight, of an enzyme;
- g) optionally from about 0.01% to about 8% by weight, of a polyolefin emulsion or suspension;
- h) optionally from about 0.01% to about 0.2% by weight, of a stabilizer;
- i) optionally from about 1% to about 80% by weight, of a fabric softening active;
- j) optionally less than about 15% by weight, of a principal solvent;
- k) optionally from about 0.5% to about 10% by weight, of a cationic nitrogen compound;
- and
- l) optionally a detersive surfactant;
- m) the balance carrier and adjunct ingredients.
