Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
An aqueous hard surface detergent composition consisting essentially of (1) a polyglycol ether condensate of a member of the group consisting of nonyl phenol having an average of about 9.5 moles of ethylene oxide per mole of condensate, octyl phenol having from 9 to 13 moles of ethylene oxide per mole of condensate, and mixtures thereof; (2) a quaternary ammonium salt selected from the group consisting of alkyl dimethyl benzyl ammonium chloride, alkyl dimethyl ethylbenzyl ammonium chloride in which the alkyl chains have from 12 to 18 carbon atoms, and mixtures thereof, and (3) a member selected from the group consisting of acylamidopropyldimethylamino acetic acid and its anion, the acyl portion of the acylamidopropyl chain being derived from the fatty acids of coconut oil; the ratio of the respective components (1), (2) and (3) being about 4.5:3:1 by weight, and total concentration of components (1), (2) and (3) being between 0.1 and 4% by weight.
Claim 2
Dependent Claim
155 words
An aqueous hard surface detergent composition consisting essentially of (1) a polyglycol ether condensate of a member of the group consisting of nonyl phenol having an average of about 9.5 moles of ethylene oxide per mole of condensate, octyl phenol having from 9 to 13 moles of ethylene oxide per mole of condensate, and mixtures thereof; (2) a quaternary ammonium salt selected from the group consisting of alkyl dimethyl benzyl ammonium chloride, alkyl dimethyl ethylbenzyl ammonium chloride in which the alkyl chains have from 12 to 18 carbon atoms, and mixtures thereof, and (3) a member selected from the group consisting of acylamidopropyldimethylamino acetic acid and its anion, the acyl portion of the acylamidopropyl chain being derived from the fatty acids of coconut oil; the ratio of the respective components (1), (2) and (3) being about 4.5:3:1 by weight, and total concentration of components (1), (2) and (3) being between 0.1 and 4% by weight.
Claim 3
Dependent Claim
16 words
The composition of claim 1 wherein the composition has a pH of about 7 to 12.
Claim 4
Dependent Claim
17 words
The composition of claim 1 wherein about 4 to 8% by weight of alkaline builders are present.
Claim 5
Independent Claim
182 words
A method of degreasing hard surfaces which comprises applying to such surfaces an effective amount, sufficient to emulsify grease adhering to said surfaces and thereby degrease said surfaces, of an aqueous detergent composition consisting essentially of (1) a polyglycol ether condensate of a member of the group consisting of nonyl phenol having an average of about 9.5 moles of ethylene oxide per mole of condensate, octyl phenol having from 9 to 13 moles of ethylene oxide per mole of condensate, and mixtures thereof; (2) a quaternary ammonium salt selected from the group consisting of alkyl dimethyl benzyl ammonium chloride, alkyl dimethyl ethylbenzyl ammonium chloride in which the alkyl chains have from 12 to 18 carbon atoms, and mixtures thereof, and (3) a member selected from the group consisting of acylamidopropyldimethylamino acetic acid and its anion, the acyl portion of the acylamidopropyl chain being derived from the fatty acids of coconut oil; the ratio of the respective components (1), (2) and (3) being about 4.5:3:1 by weight, and total concentration of components (1), (2) and (3) being between 0.1 and 4% by weight.
Claim 6
Independent Claim
182 words
A method of degreasing hard surfaces which comprises applying to such surfaces an effective amount, sufficient to emulsify grease adhering to said surfaces and thereby degrease said surfaces, of an aqueous detergent composition consisting essentially of (1) a polyglycol ether condensate of a member of the group consisting of nonyl phenol having an average of about 9.5 moles of ethylene oxide per mole of condensate, octyl phenol having from 9 to 13 moles of ethylene oxide per mole of condensate, and mixtures thereof; (2) a quaternary ammonium salt selected from the group consisting of alkyl dimethyl benzyl ammonium chloride, alkyl dimethyl ethylbenzyl ammonium chloride in which the alkyl chains have from 12 to 18 carbon atoms, and mixtures thereof, and (3) a member selected from the group consisting of acylamidopropyldimethylamino acetic acid and its anion, the acyl portion of the acylamidopropyl chain being derived from the fatty acids of coconut oil; the ratio of the respective components (1), (2) and (3) being about 4.5:3:1 by weight, and total concentration of components (1), (2) and (3) being between 0.1 and 4% by weight.
Claim 7
Dependent Claim
19 words
The method of claim 4 wherein the composition also includes about 4 to 8% by weight of alkaline builders.
