Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
A light duty, liquid detergent consisting essentially of 10 to 35% by weight of at least one water-soluble salt of a sulfonate alpha olefin containing about 12 to 18 carbon atoms, about 7.5 to about 10% by weight of an alkanoic acid diethanolamide having 12 to 14 carbon atoms in its alkanoyl radical, the weight ratio of olefin sulfonate to said diethanolamide being from about 3:1 to about 1:1, and an aqueous medium selected from the group consisting of water and a mixture of water with a solubilizer selected from the group consisting of 1 to 10% by weight of a C 2 -C 3 monohydric alcohol, 0.5 to 10% by weight of a sodium potassium, ammonium or mono-, di- or triethanolammonium salt of C 1 -C 3 alkylbenzene sulfonate or C 5 -C 6 alkyl sulfate, and mixtures thereof, about 1 to about 8% by weight of a water-soluble salt of allyl sulfonic acid as an anti-gelling agent, said composition containing less than 5% of the total detergent weight of additional compatible non-cationic detergents.
Claim 2
Dependent Claim
175 words
A light duty, liquid detergent consisting essentially of 10 to 35% by weight of at least one water-soluble salt of a sulfonate alpha olefin containing about 12 to 18 carbon atoms, about 7.5 to about 10% by weight of an alkanoic acid diethanolamide having 12 to 14 carbon atoms in its alkanoyl radical, the weight ratio of olefin sulfonate to said diethanolamide being from about 3:1 to about 1:1, and an aqueous medium selected from the group consisting of water and a mixture of water with a solubilizer selected from the group consisting of 1 to 10% by weight of a C 2 -C 3 monohydric alcohol, 0.5 to 10% by weight of a sodium potassium, ammonium or mono-, di- or triethanolammonium salt of C 1 -C 3 alkylbenzene sulfonate or C 5 -C 6 alkyl sulfate, and mixtures thereof, about 1 to about 8% by weight of a water-soluble salt of allyl sulfonic acid as an anti-gelling agent, said composition containing less than 5% of the total detergent weight of additional compatible non-cationic detergents.
Claim 3
Dependent Claim
27 words
The liquid detergent composition of claim 1 wherein a C 12 -C 14 alkanoic acid monoethanolamide is substituted for up to 25% by weight of the diethanolamide.
Claim 4
Dependent Claim
23 words
The liquid detergent composition of claim 1 wherein the weight ratio of olefin sulfonate to diethanolamide is from about 3:1 to about 1.5:1.
Claim 5
Dependent Claim
34 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 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 amout 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.
