Abstract:
Liquid compositions include: a) one or more anionic surfactants and b) one or more nonionic surfactants, wherein they comprise the surfactants of components a) and b) in a total concentration of >25% by weight, based on the total weight of the liquid composition, and are free from alkanolamines and salts thereof. Upon combination with bleaches, the liquid compositions exhibit a significantly higher bleaching efficacy than comparable alkanolamine-containing compositions.
