Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 126 words
A process for cleaning a soiled hard surface by applying thereto and subsequently removing therefrom a cleaning composition comprising: (a) about 0.1 to 50 weight percent alkali metal hydroxide or ammonium hydroxide; (b) about 0.1 to 40 weight percent of an alkyl glycoside having the formula: RO--(R'O).sub.x --Z.sub.y where R is a monovalent alkyl radical containing about 8 to 25 carbon atoms, O is an oxygen atom, R' is a divalent alkyl radical containing 2 to 4 carbon atoms, x is a number having an average value of 0 to about 12, Z is a reducing saccharide moiety containing 5 to 6 carbon atoms, and y is a number having an average value of aobut 1 to 10; and (c)about 10 to 95 weight percent water.
Claim 2
Dependent Claim 126 words
A process for cleaning a soiled hard surface by applying thereto and subsequently removing therefrom a cleaning composition comprising: (a) about 0.1 to 50 weight percent alkali metal hydroxide or ammonium hydroxide; (b) about 0.1 to 40 weight percent of an alkyl glycoside having the formula: RO--(R'O).sub.x --Z.sub.y where R is a monovalent alkyl radical containing about 8 to 25 carbon atoms, O is an oxygen atom, R' is a divalent alkyl radical containing 2 to 4 carbon atoms, x is a number having an average value of 0 to about 12, Z is a reducing saccharide moiety containing 5 to 6 carbon atoms, and y is a number having an average value of aobut 1 to 10; and (c)about 10 to 95 weight percent water.
Claim 3
Dependent Claim 38 words
The process of claim 1 wherein the cleaning composition comprises about 2 to 25 weight percent of alkali metal hydroxide, about 1 to 15 weight percent of the alkyl glycoside, and about 60 to 85 weight percent water.
Claim 4
Dependent Claim 65 words
The process of claim 2 wherein the alkali metal hydroxide in the cleaning composition comprises sodium hydroxide and the alkyl glycoside in the cleaning composition has the formula: RO--Z.sub.y where R is a monovalent, straight chain, saturated alkyl radical containing about 8 to 16 carbon atoms, Z is a glucoside moiety, and y is a number having an average value of about 1.0 to 5.
Claim 5
Dependent Claim 23 words
The process of claim 3 wherein the cleaning composition additionally comprises: (d) about 1 to 25 weight percent of a water-soluble organic solvent.
Claim 6
Dependent Claim 22 words
The process of claim 3 wherein the cleaning composition additionally comprises: (d) about 1 to 25 weight percent of a water-soluble builder.
Claim 7
Dependent Claim 113 words
A hard-surface cleaning composition comprising: (a) about 0.1 to 8 weight percent alkali metal hydroxide or ammonium hydroxide; (b) about 12 to 20 weight percent of an alkyl glycoside having the formula: RO--(R'O).sub.x --Z.sub.y where R is a monovalent alkyl radical containing about 8 to 25 carbon atoms, O is an oxygen atom, R' is a divalent alkyl radical containing 2 to 4 carbon atoms, x is a number having an average value of 0 to about 12, Z is a reducing saccharide moiety containing 5 or 6 carbon atoms, and y is a number having an average value of about 1 to 10; and (c) about 60 to 85 weight percent water.
Claim 8
Dependent Claim 113 words
A hard-surface cleaning composition comprising: (a) about 0.1 to 8 weight percent alkali metal hydroxide or ammonium hydroxide; (b) about 12 to 20 weight percent of an alkyl glycoside having the formula: RO--(R'O).sub.x --Z.sub.y where R is a monovalent alkyl radical containing about 8 to 25 carbon atoms, O is an oxygen atom, R' is a divalent alkyl radical containing 2 to 4 carbon atoms, x is a number having an average value of 0 to about 12, Z is a reducing saccharide moiety containing 5 or 6 carbon atoms, and y is a number having an average value of about 1 to 10; and (c) about 60 to 85 weight percent water.
Claim 9
Dependent Claim 60 words
The cleaning composition of claim 6 wherein the alkali metal or ammonium hydroxide comprises sodium hydroxide and the alkyl glycoside has the formula: RO--Z.sub.y wherein R is a monovalent, straight chain, saturated alkyl radical containing about 8 to 16 carbon atoms, Z is a glucoside moiety, and y is a number having an average value of about 1.0 to 5.
Claim 10
