Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A liquid detergent composition having reduced gelling tendency which consists essentially of 25 to 35% by weight of a mixture of the sodium salt of a sulfonated alpha olefin containing about 14 to 16 carbon atoms and an ammonium salt of an ethoxylated alcohol sulfate containing an alkyl group having an average of about 12 to 15 carbon atoms and from 1 to 5 ethenoxy groups, the weight ratio of olefin sulfonate to alcohol sulfate being about 1.1:1, and 1% to 10% by weight of a C 12 -C 14 alkanoic acid diethanolamide in 30% to 90% by weight of an aqueous medium containing from 1% to 10% by weight of ethanol, said composition containing at least 15 mole per cent of ammonium cations.
Claim 2
Dependent Claim
124 words
A liquid detergent composition having reduced gelling tendency which consists essentially of 25 to 35% by weight of a mixture of the sodium salt of a sulfonated alpha olefin containing about 14 to 16 carbon atoms and an ammonium salt of an ethoxylated alcohol sulfate containing an alkyl group having an average of about 12 to 15 carbon atoms and from 1 to 5 ethenoxy groups, the weight ratio of olefin sulfonate to alcohol sulfate being about 1.1:1, and 1% to 10% by weight of a C 12 -C 14 alkanoic acid diethanolamide in 30% to 90% by weight of an aqueous medium containing from 1% to 10% by weight of ethanol, said composition containing at least 15 mole per cent of ammonium cations.
Claim 3
Dependent Claim
29 words
A liquid detergent composition in accordance with claim 1 wherein a C 12 -C 14 alkanoic acid monoethanolamide is substituted for up to 55% by weight of said diethanolamide.
Claim 4
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 5
Dependent Claim
42 words
The liquid detergent composition of claim 3 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.
