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