Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
161 words
A detergent mixture suitable for use in aqueous liquid detergent compositions consisting essentially of (a) a water-soluble, anionically active olefin sulfonate product having 12 to 21 carbon atoms in the olefin molecular structure, (b) a water-soluble higher alkyl poly (ethenoxy) ether sulfate having 10 to 20 carbon atoms in the higher alkyl group and 1 to 5 ethenoxy groups per molecule, said olefin sulfonate product and said ether sulfate being in the form of a salt selected from the group consisting of sodium, potassium, ammonium and ethanolammonium and (c) a higher fatty acid diethanolamide in which the higher fatty acyl radical has 10 to 14 carbon atoms, the weight ratio of said sulfate to said sulfonate being in the range of 90:10 to 30:70, said diethanolamide being present in an amount of about 1/2 to 10% by weight and being effective to improve the foam stability as compared with the same composition as defined above which does not contain said diethanolamide.
Claim 2
Dependent Claim
161 words
A detergent mixture suitable for use in aqueous liquid detergent compositions consisting essentially of (a) a water-soluble, anionically active olefin sulfonate product having 12 to 21 carbon atoms in the olefin molecular structure, (b) a water-soluble higher alkyl poly (ethenoxy) ether sulfate having 10 to 20 carbon atoms in the higher alkyl group and 1 to 5 ethenoxy groups per molecule, said olefin sulfonate product and said ether sulfate being in the form of a salt selected from the group consisting of sodium, potassium, ammonium and ethanolammonium and (c) a higher fatty acid diethanolamide in which the higher fatty acyl radical has 10 to 14 carbon atoms, the weight ratio of said sulfate to said sulfonate being in the range of 90:10 to 30:70, said diethanolamide being present in an amount of about 1/2 to 10% by weight and being effective to improve the foam stability as compared with the same composition as defined above which does not contain said diethanolamide.
Claim 3
Dependent Claim
26 words
A mixture as set forth in claim 1 in which the olefin sulfonate constitutes about one third to 70% by weight of the total detergent mixture.
Claim 4
Dependent Claim
76 words
A substantially homogeneous aqueous detergent having a total solids content of 30 to 80% by weight, said solids content consisting essentially of the detergent mixture set forth in claim 1 and water-soluble sodium or potassium inorganic builder salts selected from the group consisting of phosphates, silicates, carbonates, bicarbonates, borates, sulfates and chlorides, the weight ratio of the total organic sulfonate and sulfate detergents to inorganic builder salts being in the range of about 1:1 to 1:20.
Claim 5
Dependent Claim
52 words
An aqueous detergent in accordance with claim 3 wherein said builder salts is a potassium polyphosphate and said composition further contains a water-soluble lower alkyl benzene sulfonate salt having 1-2 methyl groups on the benzene as a hydrotrope, said hydrotrope being present in an amount of from 1/2 to 10% by weight.
