Abstract
Abstract This disclosure relates to pourable bleaching compositions comprising a solid substantially water-insoluble organic peroxy acid stably suspended in an aqueous medium containing at least two polymers wherein the first polymer is one or more natural gums and the second polymer is selected from the group consisting of polyvinyl alcohol, one or more cellulose derivatives and mixtures thereof. The bleaching composition also may contain an electrolyte. The preferred organic peroxy acid is 1,12-diperoxydodecanedioic acid. The preferred first polymer is xanthan gum. The second polymer is preferably a cellulose ether.
