Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A light duty liquid detergent composition consisting essentially of about 18% to 40% by weight of a mixture of at least one water-soluble salt of a sulfonate alpha olefin containing about 12 to 18 carbon atoms and at least one water-soluble salt of an ethoxylated alkyl sulfate containing an alkyl group of 10 to 18 carbon atoms and from 1 to 5 ethenoxy groups, the weight ratio of olefin sulfonate to alkyl sulfate being from about 1.4:1 to about 1.1:1, about 1.5% to about 10% by weight of an amine oxide foam booster selected from the group consisting of tertiary amine oxides having the formula ##STR7## wherein R 1 is a higher alkyl group containing about 12 to 18 carbon atoms and R 2 and R 3 are radicals selected from the group consisting of alkyl and hydroxyalkyl groups having 1 to 4 carbon atoms, morpholino oxides having the formula ##STR8## wherein R 1 is a higher alkyl group containing about 12 to 18 carbon atoms and mixtures thereof, and about 1% to 8% by weight of sodium allyl sulfonate in an aqueous medium.
Claim 2
Dependent Claim
184 words
A light duty liquid detergent composition consisting essentially of about 18% to 40% by weight of a mixture of at least one water-soluble salt of a sulfonate alpha olefin containing about 12 to 18 carbon atoms and at least one water-soluble salt of an ethoxylated alkyl sulfate containing an alkyl group of 10 to 18 carbon atoms and from 1 to 5 ethenoxy groups, the weight ratio of olefin sulfonate to alkyl sulfate being from about 1.4:1 to about 1.1:1, about 1.5% to about 10% by weight of an amine oxide foam booster selected from the group consisting of tertiary amine oxides having the formula ##STR7## wherein R 1 is a higher alkyl group containing about 12 to 18 carbon atoms and R 2 and R 3 are radicals selected from the group consisting of alkyl and hydroxyalkyl groups having 1 to 4 carbon atoms, morpholino oxides having the formula ##STR8## wherein R 1 is a higher alkyl group containing about 12 to 18 carbon atoms and mixtures thereof, and about 1% to 8% by weight of sodium allyl sulfonate in an aqueous medium.
Claim 3
Dependent Claim
49 words
The liquid detergent composition of claim 1 wherein a C 12 -C 14 alkanoic acid amide foam booster selected from the group consisting of alkanoic acid monoethanolamide, alkanoic acid diethanolamide and ethoxylated alkanoic aicd monoethanolamide is substituted for up to 60% by weight of the amine oxide foam booster.
Claim 4
Dependent Claim
23 words
The liquid detergent composition of claim 1 wherein the weight of olefin sulfonate to alcohol sulfate is from about 1.3:1 to about 1.1:1
Claim 5
Dependent Claim
35 words
The liquid detergent composition of claim 1 which further includes from about 0.25% to about 3% by weight of a water soluble protein hydrolysate having a molecular weight of from about 120 to about 20,000.
Claim 6
Dependent Claim
42 words
The liquid detergent composition of claim 4 wherein said protein hydrolysate is derived from collagen and has a molecular of from 500 to 10,000 and is present in the amount of from about 1% to 2% by weight of the detergent composition.
Claim 7
Dependent Claim
92 words
The liquid detergent composition of claim 1 wherein the olefin sulfonate has an average of about 14 to 16 carbon atoms and is produced by sulfonating an olefin mixture containing about 75 to 85% by weight straight chain alpha olefin, about 8 to 20% by weight vinylidene olefin and about 5 to 12% by weight internal straight chain olefin, with sulfur trioxide in a molar ratio of olefin mixture to sulfur trioxide of about 1:1 to 1.2:1 and subsequently neutralizing the sulfonated mixture and converting sultones therein to sulfonic acids by ring-opening.
Claim 8
Dependent Claim
75 words
The liquid detergent composition of claim 1 wherein the aqueous medium is water or a mixture of water and a solubilizer selected from the group consisitng of 1% to 10% by weight of C 2 -C 3 monohydric alcohols, 0% to 6% by weight of a sodium, potassium, ammonium, or mono-, di- or triethanolammonium salt of a C 1 -C 3 alkyl substituted benzene sulfonate or C 5 -C 6 alkyl sulfate and mixtures thereof.
Claim 9
Dependent Claim
30 words
The liquid detergent composition of claim 7 wherein said mixture is about 25% to 35% by weight and the amine oxide foam booster is about 2% to 8% by weight.
