Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
A detergent composition comprising: (A) from about 1% to about 90% of an alkylpolysaccharide detergent surfactant of the formula RO(R'O) y (Z) x where R is an alkyl, hydroxy alkyl, alkyl phenyl, hydroxy alkyl phenyl, alkyl benzyl, or mixtures thereof, said alkyl groups containing from about 8 to about 18 carbon atoms; where each R' contains from 2 to about 4 carbon atoms and y is from 0 to about 12; and where each Z is a moiety derived from a reducing saccharide containing 5 or 6 carbon atoms, and x is a number from about 1½ to about 10; (B) from about 1% to about 90% of a nonionic detergent surfactant; and (C) from 0% to about 90% of a detergency builder; the ratio of (A) to (B) being from about 1:10 to about 10:1.
Claim 2
Dependent Claim
136 words
A detergent composition comprising: (A) from about 1% to about 90% of an alkylpolysaccharide detergent surfactant of the formula RO(R'O) y (Z) x where R is an alkyl, hydroxy alkyl, alkyl phenyl, hydroxy alkyl phenyl, alkyl benzyl, or mixtures thereof, said alkyl groups containing from about 8 to about 18 carbon atoms; where each R' contains from 2 to about 4 carbon atoms and y is from 0 to about 12; and where each Z is a moiety derived from a reducing saccharide containing 5 or 6 carbon atoms, and x is a number from about 1½ to about 10; (B) from about 1% to about 90% of a nonionic detergent surfactant; and (C) from 0% to about 90% of a detergency builder; the ratio of (A) to (B) being from about 1:10 to about 10:1.
Claim 3
Dependent Claim
