Detergent compositions

Claim 1

An aqueous detergent composition comprising from 70% to 85% water and, as the active component thereof, from 15% to 30% of a mixture consisting essentially of: (A) 3 to 6 parts by weight of nitrilotriacetic acid or ethylenediamine tetraacetic acid in free acid or salt form; (B) 2 to 11 parts by weight of a nonylphenol polyglycol ether having an average of 8 to 12 glycol units per molecule; (C) 5 to 15 parts by weight of mono-, di- or tri- ethanolamine; (D) 1 to 3 parts by weight of a block copolymer of propylene oxide and ethylene oxide containing an average of 28 to 32 propylene oxide units per molecule to which an average of 8 to 12% by weight of ethylene oxide units are copolymerized; (E) 0 to 3 parts by weight of a C 8 to C 14 branched chain, primary alcohol; and (F) 0 to 1 parts by weight of a water-soluble, silicone oil, and, as an optional solvent component thereof, from: (G) 10 to 40 parts, based on the total weight of the aqueous mixture of active components, of an aliphatic or aromatic hydrocarbon, a chlorinated hydrocarbon, or a mixture thereof; or (H) 5 to 20 parts, based on the total weight of the aqueous mixture of active components, of a C 1 to C 3 alcohol or a water-soluble glycol, or a mixture of solvent components (G) and (H), with the proviso that when solvent component (G) is absent, active component (B) is present in an amount of from 2 to 6 parts by weight.
