Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
91 words
A method of conditioning hair which comprises applying to said hair an effective amount of a composition which comprises: A. from about 0.1 to about 10.0 weight weight percent based on the total weight of the composition of water insoluble polyelectrolyte complex which is the ionic reaction product of one or more polycationic polymers having a cationic charge density of not more than 0.004 and one or more polyanionic polymers; and B. water, wherein said polyelectrolyte complex provides improved wave-setting capacity over that shown individually by said polycationic or polyanionic polymers.
Claim 2
Independent Claim
91 words
A method of conditioning hair which comprises applying to said hair an effective amount of a composition which comprises: A. from about 0.1 to about 10.0 weight weight percent based on the total weight of the composition of water insoluble polyelectrolyte complex which is the ionic reaction product of one or more polycationic polymers having a cationic charge density of not more than 0.004 and one or more polyanionic polymers; and B. water, wherein said polyelectrolyte complex provides improved wave-setting capacity over that shown individually by said polycationic or polyanionic polymers.
Claim 3
Dependent Claim
26 words
A method according to claim 1 wherein the polycationic polymer used in preparing said polyelectrolyte complex had a cationic charge density not more than about 0.0015.
Claim 4
Dependent Claim
86 words
A method according to claim 1 wherein said polyelectrolyte complex is composed of a quaternary nitrogen containing cellulose ether having the structure: ##STR6## wherein: R cell is a residue of an anhydroglucose unit; Y is an integer from 50 to 20,000; R individually represents a substituent of the general formula: ##STR7## wherein m is an integer from 0 to 10, n is an integer from 0 to 3 and p is an integer from 0 to 10, and a polycarboxylic acid or a carboxylic cellulosic ether.
Claim 5
Dependent Claim
25 words
A method according to claim 1 comprising up to about 30 weight percent of an amphoteric, non-ionic, polar non-ionic, zwitterionic, anionic surfactant or mixtures thereof.
Claim 6
Dependent Claim
25 words
A method according to claim 2 comprising up to about 30 weight percent of an amphoteric, non-ionic, polar non-ionic, zwitterionic, anionic surfactant or mixtures thereof.
Claim 7
Dependent Claim
24 words
A method according to claim 4 wherein said surfactant is sodium lauryl diethoxy sulfate triethanolamine lauryl sulfate, sodium dodecyl sulfate or a combination thereof.
Claim 8
Dependent Claim
52 words
A method according to claim 4 wherein said surfactant is a long chain imidazole derivative of the formula: ##STR8## wherein: R is an acrylic hydrophobic group having from about 8 to about 18 carbon atoms; G is a hydroxyl, chloride, sulfate or surface active sulfate or sulfonate group; M is a cation.
