Abstract
An aqueous liquid bleaching composition is described having a pH from 1 to 6.5 and comprising a solid, particulate, substantially water-insoluble organic peroxy acid such as diperoxydodecanedioic acid. This peroxy acid is stably suspended in an aqueous liquid by a structuring combination of anionic surfactant, ethoxylated nonionic surfactant, and fatty acid.
