Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
An aqueous hair conditioner composition consisting essentially of (1) from about 0.5 to 4.5 percent by weight of a dimethyl di(hydrogenated tallow) ammonium salt, (2) from about 0.5 to 2.0 percent by weight of a quaternized hydrolyzed collagen protein in which 90 percent of the protein amino groups have been substituted with a quaternary of the stearyl trimethyl ammonium chloride type and having a molecular weight of about 12,500, (3) from about 0.1 to 0.5 percent by weight of a cationic quaternized polymer of hydroxyethyl cellulose and (4) from about 1.3 to 1.7 percent by weight, based on the weight of the composition of a mixture of long chain fatty alcohols comprising at least 90 percent by weight of said mixture of C 16 and C 18 alcohols in a ratio of about 1:2, respectively and the balance water.
Claim 2
Dependent Claim
139 words
An aqueous hair conditioner composition consisting essentially of (1) from about 0.5 to 4.5 percent by weight of a dimethyl di(hydrogenated tallow) ammonium salt, (2) from about 0.5 to 2.0 percent by weight of a quaternized hydrolyzed collagen protein in which 90 percent of the protein amino groups have been substituted with a quaternary of the stearyl trimethyl ammonium chloride type and having a molecular weight of about 12,500, (3) from about 0.1 to 0.5 percent by weight of a cationic quaternized polymer of hydroxyethyl cellulose and (4) from about 1.3 to 1.7 percent by weight, based on the weight of the composition of a mixture of long chain fatty alcohols comprising at least 90 percent by weight of said mixture of C 16 and C 18 alcohols in a ratio of about 1:2, respectively and the balance water.
Claim 3
Dependent Claim
20 words
The composition of claim 1 wherein the weight ratio of quaternized collagen protein and fatty alcohol mixture is about 1:1.
Claim 4
Dependent Claim
15 words
The composition of claim 1 wherein said ammonium salt is dimethyl di(hydrogenated tallow) ammonium chloride.
Claim 5
Dependent Claim
42 words
The composition of claim 1 wherein the amount of said ammonium salt is from about 2 to 3 percent, the amount of protein is from about 0.75 to 1.5 percent and the amount of cellulose is from about 0.2 to 0.4 percent.
Claim 6
Dependent Claim
29 words
The composition of claim 1 wherein said mixture of fatty alcohols is a mixture containing at least 90 percent cetyl alcohol and stearyl alcohol in a ratio of 1:2.
