Abstract
A single phase aqueous liquid laundry product containing a hydrogen peroxide bleach has a detergency effective amount of a nonionic surfactant or a mixture of a nonionic surfactant and an anionic surfactant and a brightening agent. In an embodiment the liquid product additionally contains a cationic fabric softener which provides for effective softening of fabrics as well as reduction of static cling. The product is stable for long periods of time and is effective for pretreatment stain removal.
