Abstract

This invention relates to a novel non-aqueous liquid oxygen bleach composition prepared by dispersing solid peroxygen compound in the liquid in which the content of an anhydrous non-polar organic solvent and a non-ionic and anionic surfactant is controlled. The composition is formed in a high viscous paste or a gel-type suspension and can be used as a multi-purpose composition, for example, the bleach and stain remover of clothes and the cleanser of bathroom and kitchen since they have a chemical/physical stability of no loss of available oxygen, an excellent bleaching and cleaning ability due to their alkaline pH range, no change of viscosity or no phase separation during the storage and so on.
