Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 277 words
A detergent composition consisting essentially of (A) from 0.01 to 10% by weight of an organic phosphoric acid ester having the formula (I), or mixtures thereof: O = P--O--(CH.sub.2 CH.sub.2 O).sub.n C.sub.m H.sub.2m+1 ].sub.3 (I) wherein n is 1, 2 or 3 and m is 2, 3 or 4, (B) from 0.1 to 20% by weight of ammonia or alkanolamine having the formula (II): nh.sub.n' (C.sub.m' H.sub.2m' OH).sub.3-n' (II) wherein n' is zero or an integer of from one to 3 and m' is 2 or 3, or a water-soluble inorganic alkaline agent selected from the group consisting of alkali metal hydroxides, alkali metal polyphosphates, alkali metal silicates, alkali metal metasilicates, alkali metal carbonates and alkali metal phosphates, or mixtures thereof, (C) from 0.1 to 10% by weight of a water-soluble organic anionic surface active agent selected from the group consisting of olefin (C 10 to C 20 ) sulfonates, alkyl (C 10 to C 20 ) sulfates, alkane (C 10 to C 20 ) sulfonates, alkyl (C 8 to C 10 ) benzene sulfonates and alkyl (C 10 to C 20 ) ether sulfates containing one to 10 moles of ethylene oxide, a water-soluble organic non-ionic surface active agent selected from the group consisting of polyoxyethylene nonylphenyl ethers containing 4 to 20 moles of ethylene oxide, polyoxyethylene dodecylphenyl ethers containing 4 to 20 moles of ethylene oxide, n-, iso- and sec-higher alcohol ethers of polyoxyethylene having an alkyl chain length of 10 to 18 carbons and containing 4 to 20 moles of ethylene oxide and fatty acid ethanolamides and propanolamides having 10 to 18 carbon atoms, or mixtures thereof, and (D) the balance is essentially water.
Claim 2
Dependent Claim 277 words
A detergent composition consisting essentially of (A) from 0.01 to 10% by weight of an organic phosphoric acid ester having the formula (I), or mixtures thereof: O = P--O--(CH.sub.2 CH.sub.2 O).sub.n C.sub.m H.sub.2m+1 ].sub.3 (I) wherein n is 1, 2 or 3 and m is 2, 3 or 4, (B) from 0.1 to 20% by weight of ammonia or alkanolamine having the formula (II): nh.sub.n' (C.sub.m' H.sub.2m' OH).sub.3-n' (II) wherein n' is zero or an integer of from one to 3 and m' is 2 or 3, or a water-soluble inorganic alkaline agent selected from the group consisting of alkali metal hydroxides, alkali metal polyphosphates, alkali metal silicates, alkali metal metasilicates, alkali metal carbonates and alkali metal phosphates, or mixtures thereof, (C) from 0.1 to 10% by weight of a water-soluble organic anionic surface active agent selected from the group consisting of olefin (C 10 to C 20 ) sulfonates, alkyl (C 10 to C 20 ) sulfates, alkane (C 10 to C 20 ) sulfonates, alkyl (C 8 to C 10 ) benzene sulfonates and alkyl (C 10 to C 20 ) ether sulfates containing one to 10 moles of ethylene oxide, a water-soluble organic non-ionic surface active agent selected from the group consisting of polyoxyethylene nonylphenyl ethers containing 4 to 20 moles of ethylene oxide, polyoxyethylene dodecylphenyl ethers containing 4 to 20 moles of ethylene oxide, n-, iso- and sec-higher alcohol ethers of polyoxyethylene having an alkyl chain length of 10 to 18 carbons and containing 4 to 20 moles of ethylene oxide and fatty acid ethanolamides and propanolamides having 10 to 18 carbon atoms, or mixtures thereof, and (D) the balance is essentially water.
