Abstract
Abstract There is disclosed a hair rinse conditioner which is capable of imparting a degree of set to the hair. The conditioner comprises, in an aqueous medium, a cationic surfactant which is present in lamellar phase and a latex of particles of a water-insoluble film-forming polymer, which latex has a minimum film-forming temperature in the range 15° C. to 50° C.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
98 words
A hair rinse conditioner preparation comprising, in an aqueous medium, about 0.1% to about 5% by weight of the preparation of a cationic surfactant which is present in disperse lamellar phase; from about 0.1% to about 5% by weight of a higher fatty alcohol having 8-22 carbon atoms; and a latex of particles of a water insoluble film-forming polymer, wherein said polymer is present in an amount of from about 0.5% to about 10% by weight of the preparation, which latex has a minimum film-forming temperature of 15° to 50° C., the preparation not containing a cationic polymer.
Claim 2
Dependent Claim
98 words
A hair rinse conditioner preparation comprising, in an aqueous medium, about 0.1% to about 5% by weight of the preparation of a cationic surfactant which is present in disperse lamellar phase; from about 0.1% to about 5% by weight of a higher fatty alcohol having 8-22 carbon atoms; and a latex of particles of a water insoluble film-forming polymer, wherein said polymer is present in an amount of from about 0.5% to about 10% by weight of the preparation, which latex has a minimum film-forming temperature of 15° to 50° C., the preparation not containing a cationic polymer.
Claim 3
Dependent Claim
18 words
A hair conditioner preparation as claimed in claim 1 wherein the cationic surfactant is a quaternary ammonium salt.
Claim 4
Dependent Claim
30 words
A hair conditioner preparation as claimed in claim 1 wherein the cationic surfactant is present in an amount of from about 0.2% to about 3% by weight of the preparation.
Claim 5
Dependent Claim
34 words
A hair conditioner preparation as claimed in claim 1 wherein the water-insoluble film-forming polymer is poly(vinyl acetate), a copolymer of styrene and an alkyl acrylate or a copolymer of vinyl acetate and acrylic acid.
Claim 6
Dependent Claim
29 words
A hair conditioner preparation as claimed in claim 1 wherein the amount of the water-insoluble film-forming polymer is from about 1% to about 10% by weight of the preparation.
Claim 7
Dependent Claim
103 words
A hair rinse conditioner preparation as claimed in claim 1 comprising, in an aqueous medium, about 0.1% to about 0.5% by weight of a quaternary ammonium cationic surfactant which is present in the aqueous medium in disperse lamellar phase and a latex of particles of a water-insoluble polymer selected from the group consisting of poly(vinyl acetate), copolymers of styrene and an alkyl acrylate and copolymers of vinyl acetate and acrylic acid, said latex having a minimum film forming temperature in the range 15° to 50° C. and said water-insoluble polymer constituting about 0.5% to about 10% by weight of the hair conditioner preparation.
Claim 8
Dependent Claim
25 words
A hair conditioner preparation as claimed in claim 1 wherein the film forming temperature of said latex is in the range 15° to 35° C.
Claim 9
Dependent Claim
19 words
A hair conditioner preparation as claimed in claim 1, wherein the higher fatty alcohol has from 16-20 carbon atoms.
Claim 10
Dependent Claim
28 words
A hair conditioner preparation as claimed in claim 1, wherein the higher fatty alcohol is selected from the group consisting of cetyl alcohol, stearyl alcohol and mixtures thereof.
Claim 11
Dependent Claim
72 words
A method of preparing an aqueous hair rinse conditioner preparation as claimed in claim 1 comprising preparing a solution of cationic surfactant, the higher fatty alcohol, and water, wherein said solution contains 90% by weight of the total cationic surfactant present in the rinse conditioner preparation; adding the remaining 10% of the cationic surfactant to the latex of particles of the water-insoluble film-forming polymer; and incorporating the resulting latex into said solution.
