Substituted-butanediperoxoic acids represented by the formula ##STR1## wherein R is alkyl of 6 to 18 carbon atoms or phenyl are useful oxidizing agents. These substituted-butanediperoxoic acids are useful as bleaching agents and disinfecting agents.

Substituted-butanediperoxoic acids and process for bleaching

Novel monoalkyl oxybisacetates are attractively useful as surfactants, and particularly in detergent compositions.

Novel surfactants useful in detergent compositions

A substantially stable, crystalline dipotassium N-chloroimidodisulfate is useful as a bleach to remove stains from soiled fabrics when dissolved in an aqueous solution.

Detergent compositions containing dipotassium N-chloroimidodisulfate

A fabric bleaching composition is provided which consists essentially of water and a bleach selected from the group consisting of disodium chloroimidodisulfate, dipotassium chloroimidodisulfate and mixtures thereof. The fabric bleaching composition can also contain a detergent, a buffering agent and other ingredients in a detergent formulation. The fabric bleaching composition is intermediate in strength between peroxide-type fabric bleaches and alkali metal hypochlorite fabric bleaches.

Chloroimide fabric bleaches

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.
