A bleaching composition comprises:
(A) hydrogen peroxide and/or a hydrogen peroxide addition compound such as a percarbonate; and
(B) at least one activator which is a nitrogen-containing heterocyclic compound in which a halogen atom is substituted for the hydrogen atom of the secondary amino group or a non-heterocyclic N-halo-hindered amine compound, the hydrolysis constant of the activator being within the range of 1 x 10⁻¹⁰ to 5 x 10⁻⁶ (at 25°C). Examples of the activator include 1-chloro-piperidine, 1-chloro-2-methyl-piperidine, 1-chloro-isonipecotic acid, 1-chloro- -hexamethyleneimine and 1-chloro-ε-caprolactam. The bleaching-detergent composition may also contain the components (A) and (B) together with a surfactant. These compositions exhibit an excellent effect concerning bleaching at low temperature, but hardly affect the colors of colored and patterned clothes.
