Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A shampoo composition comprising: (A) a quaternary ammonium compound having at least one unsaturated long chain substituent and having an iodine value of from about 10 to about 85; (B) from about 1% to about 6% of a long chain acyl derivative selected from the group consisting of long chain amides, alkanol amides, esters of glycerine, esters of ethylene glycol, esters of carboxylic acids, esters of thiocarboxylic acids and mixtures thereof; (C) from about 10% to about 25% of a surfactant selected from the group consisting of higher alkyl betaines and mixtures of higher alkyl betaines and higher alkyl sultaines; and, (D) from about 50% to about 80% water; wherein said quaternary compound is present at a level equal to from about 15% to about 40% of the level of said surfactant.
Claim 2
Dependent Claim
132 words
A shampoo composition comprising: (A) a quaternary ammonium compound having at least one unsaturated long chain substituent and having an iodine value of from about 10 to about 85; (B) from about 1% to about 6% of a long chain acyl derivative selected from the group consisting of long chain amides, alkanol amides, esters of glycerine, esters of ethylene glycol, esters of carboxylic acids, esters of thiocarboxylic acids and mixtures thereof; (C) from about 10% to about 25% of a surfactant selected from the group consisting of higher alkyl betaines and mixtures of higher alkyl betaines and higher alkyl sultaines; and, (D) from about 50% to about 80% water; wherein said quaternary compound is present at a level equal to from about 15% to about 40% of the level of said surfactant.
Claim 3
Dependent Claim
25 words
A shampoo composition according to claim 1 wherein the long chain acyl derivative is present at a level of from about 1% to about 4%.
Claim 4
Dependent Claim
37 words
A shampoo composition according to claim 2 wherein the quaternary ammonium compound is present at a level equal to from about 20% to about 40% of the level of the betaine or the betaine and sultaine mixture.
Claim 5
Dependent Claim
22 words
A shampoo composition according to claim 3 wherein the surfactant is present at a level of from about 15% to about 25%.

Claim 7
Dependent Claim
35 words
A shampoo composition according to claim 5 wherein the quaternary ammonium compound is selected from the group consisting of di-softened tallow dimethylammonium chloride, dioleyl dimethylammonium chloride, methyl-1-oleyl amido ethyl-2-oleyl imidazolinium methyl sulfate and mixtures thereof.
Claim 8
Dependent Claim
26 words
