Liquid hydrogen peroxide bleach containing a peracid activator

Abstract

Storage-stable, low temperature-active liquid hydrogen peroxide laundry bleaching compositions are provided. The compositions contain a dispersion of a solid particulate peracid activator in acidic aqueous hydrogen peroxide. The activator is insoluble at the acidic conditions of storage but dissolves and activates the hydrogen peroxide at the alkaline conditions of use in laundry. Optionally the bleaching compositions can contain optical brighteners, surfactants, and/or fabric softeners.
