Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A detergent composition comprising: (1) an alkylpolysaccharide detergent surfactant having the formula RO(R 1 O) t Z x wherein R is an alkyl, alkylphenol, hydroxyalkyl, hydroxy alkylphenol, or mixtures thereof, and said alkyl groups contain from about 8 to about 18 carbon atoms; wherein each R contains from 2 to about 4 carbon; wherein t is from 0 to about 5; wherein Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms; and wherein x is from about 11 to about 3; (2) a calcium sensitive anionic detergent cosurfactant; and (3) from 0% to 95% of a detergent builder, the ratio of (2) to (1) being from 1:1 to 6:1 on a molar basis and the free fatty alcohol content being less than 2%.
Claim 2
Dependent Claim
130 words
A detergent composition comprising: (1) an alkylpolysaccharide detergent surfactant having the formula RO(R 1 O) t Z x wherein R is an alkyl, alkylphenol, hydroxyalkyl, hydroxy alkylphenol, or mixtures thereof, and said alkyl groups contain from about 8 to about 18 carbon atoms; wherein each R contains from 2 to about 4 carbon; wherein t is from 0 to about 5; wherein Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms; and wherein x is from about 11 to about 3; (2) a calcium sensitive anionic detergent cosurfactant; and (3) from 0% to 95% of a detergent builder, the ratio of (2) to (1) being from 1:1 to 6:1 on a molar basis and the free fatty alcohol content being less than 2%.
Claim 3
Dependent Claim
18 words
The composition of Claim 1 wherein t is 0, and x is from 1 1/2 to 2 1/2.
Claim 4
Dependent Claim
67 words
The composition of Claim 1 wherein said calcium sensitive anionic detergent cosurfactant has the formula R(SO 3 ) y (COO) z (OSO 3 ) n M q wherein R has the meaning given hereinbefore; y, z and n are numbers from 0 to 4; y + z + n is from 1 to 3, M rs a cationic moiety; and q is selected to complete the formula.
Claim 5
Dependent Claim
34 words
The composition of Claim 3 wherein said alkyl groups contain from 10 to 14 carbon atoms, and Z is selected from the group consisting of glucose, galactose, glucosyl, and galactosyl residues and mixtures thereof.
Claim 6
Dependent Claim
49 words
The compositions of Claim 4 wherein the anionic detergent cosurfactant is an alkyl sulfate containing from 6 to 30 carbon atoms or an alkyl benzene sulfonate in which the alkyl contains from 6 to 20 carbon atoms; or a fatty acid soap containing from 6 to 30 carbon atoms,
Claim 7
Dependent Claim
19 words
The composition of Claims 1 or 3 wherein the ratio of (2) to (1) is from 2;1 to 4:1.
