ABSTRACT:
The alkali metal salts of imidobis sulfuric acid, particularly the trisodium salt, is effective in heavy duty laundry detergent compositions by reducing the damaging effects of chlorine-containing bleaches on the fabric while minimizing the loss in effectiveness of the bleach in removing stains from the soiled fabric. Accordingly, a detergent composition is provided which comprises, based on the total weight of the composition, at least 5 percent by weight of a surfactant selected from the group consisting of anionic, nonionic, zwitterionic, ampholytic and amphoteric surfactants, at least 5 percent by weight of a builder, and a bleach-damage mitigating amount of trisodium imidobis sulfate, tripotassium imidobis sulfate or mixtures thereof. A process for washing soiled fabrics is also provided comprising contacting the fabrics with a detergent, a chlorine-containing bleach, and a bleach-damage mitigating amount of the alkali metal imidobis sulfate.
