Abstract
A bleaching composition, effective to remove stains on fabrics and safe for dyed fabrics, includes a water soluble peroxymonosulfate bleach, a water soluble inorganic bromide which promotes the bleaching activity of the peroxymonosulfate and an N-hydrogen compound of a certain type, such as para-toluene sulfonamide or 5,5-dimethylhydantoin, which inhibits destruction of dyes and overbleaching of dyed materials while stains to be bleached by the composition are effectively removed. Also within the invention are bleaching detergent compositions which also contain a normally solid, water soluble synthetic organic detergent, such as an anionic detergent which is a sodium linear higher alkylbenzene sulfonate or a nonionic detergent which is a fatty alcohol polyethylene oxide condensate, or a mixture thereof, and which may also include a builder salt. Methods of bleaching and simultaneously washing and bleaching with such compositions or their components are also disclosed.
