Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
203 words
A concentrated aqueous liquid detergent composition comprising: (1) from about 35% to about 75% of detergent surfactant having the formula RO(R 1 O) y SO 3 M wherein R is an alkyl group containing from about 8 to about 20 carbon atoms, R 1 is ethylene or propylene, y is a number from about 1 to about 15, and M is a compatible cationic group; (2) from about 1% to about 35% of a detergent surfactant having the formula R 2 O(R 3 O) y (Z) x where Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms; x is a number from about 11/2 to about 8 as an average; R is an alkyl, alkylphenyl, hydroxy alkylphenyl, or hydroxyalkyl hydrophobic group containing from about 6 to about 30 carbon atoms; each R 1 is an ethoxy, propoxy or glyceryl group; and Y is from 0 to about 10; the ratio of carbons in the hydrophobic group to the number of saccharide moieties being from about 1:1 to about 30:1; and (3) the balance being selected from the group consisting of water, lower molecular weight alcohols containing from 1 to about 4 carbon atoms, and mixtures thereof.
Claim 2
Dependent Claim
203 words
A concentrated aqueous liquid detergent composition comprising: (1) from about 35% to about 75% of detergent surfactant having the formula RO(R 1 O) y SO 3 M wherein R is an alkyl group containing from about 8 to about 20 carbon atoms, R 1 is ethylene or propylene, y is a number from about 1 to about 15, and M is a compatible cationic group; (2) from about 1% to about 35% of a detergent surfactant having the formula R 2 O(R 3 O) y (Z) x where Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms; x is a number from about 11/2 to about 8 as an average; R is an alkyl, alkylphenyl, hydroxy alkylphenyl, or hydroxyalkyl hydrophobic group containing from about 6 to about 30 carbon atoms; each R 1 is an ethoxy, propoxy or glyceryl group; and Y is from 0 to about 10; the ratio of carbons in the hydrophobic group to the number of saccharide moieties being from about 1:1 to about 30:1; and (3) the balance being selected from the group consisting of water, lower molecular weight alcohols containing from 1 to about 4 carbon atoms, and mixtures thereof.
