Abstract
Liquid compositions having a pH up to 7 comprise from 0.01% to 20% by weight of the total composition of a peroxygen bleach, from 0.001% to 30% by weight of the total composition of an ethoxylated nonionic surfactant, from 0.001% to 20% by weight of a zwitterionic betaine surfactant at a weight ratio of the ethoxylated nonionic surfactant to the zwitterionic betaine surfactant of from 0.01 to 20. These compositions are suitable to deliver improved stain removal performance and improved bleaching performance on various inanimate surfaces.
