Abstract

An aqueous cleaning composition, which may be suitable for use in cleaning hard surfaces, is described. The aqueous cleaning composition includes an ionic liquid solvent, an amino alcohol, and a substantial amount of water. The cleaning compositions may also include a disinfecting quaternary surfactant, a nonionic surfactant, such as an ethoxylated alcohol and/or alkyl polyglycoside, and/or a chelating agent, such as an aminopolycarboxylate chelating agent.

(c) aminopolycarboxylate chelating agent;
(d) nonionic surfactant;
(e) 0 to about 1 wt. % disinfecting quaternary surfactant; and
(f) optionally, fragrance and/or bleaching agent,
(g) at least about 85 wt. % water.

2. An aqueous cleaning composition consisting essentially of:
