Abstract
Abstract A hair rinse composition which comprises at least one cationic surface active agent and a decomposition derivative of a keratin material which have been dissolved or dispersed in a suitable solvent. The decomposition derivative is a member selected from hydrolysates of keratin material, alkali salts of decomposition products obtained by oxidation of keratin material, alkali salts of derivatives at a thiol group of decomposition products obtained by reduction of keratin material and a mixture thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A hair rinse composition comprising 0.01 to 10 wt.% at least one cationic surface active agent and 0.01 to 10 wt.% a decomposition derivative of a keratin material selected from the group consisting of (1) alkali salts of decomposition products obtained by oxidation of keratin material, (2) alkali salts of derivatives at a thiol group of decomposition products obtained by reduction of keratin material, and a mixture thereof, these components having been dispersed or dissolved in a solvent.
Claim 2
Dependent Claim
78 words
A hair rinse composition comprising 0.01 to 10 wt.% at least one cationic surface active agent and 0.01 to 10 wt.% a decomposition derivative of a keratin material selected from the group consisting of (1) alkali salts of decomposition products obtained by oxidation of keratin material, (2) alkali salts of derivatives at a thiol group of decomposition products obtained by reduction of keratin material, and a mixture thereof, these components having been dispersed or dissolved in a solvent.
Claim 3
Dependent Claim
92 words
A hair rinse composition according to claim 1, wherein said at least one cationic surface active agent is a quaternary ammonium salt represented by the general formula ##STR6## (in which one or two or R 1 , R 2 , R 3 and R 4 represent a long chain alkyl group or a long chain hydroxyalkyl group having 8-20 carbon atoms and the other represent an alkyl group or hydroxyalkyl group having 1-3 carbon atoms, or a benzyl group, and X represents a halogen atom or an alkylsulfate having 1-2 carbon atoms).
Claim 4
Dependent Claim
35 words
The hair rinse composition of claim 1 wherein said decomposition derivative of a keratin material is an alkali salt of a derivative at a thiol group of decomposition products obtained by reduction of keratin material.
Claim 5
Dependent Claim
25 words
A hair rinse composition according to claim 3, wherein the derivative at the thiol group is a member selected from the group consisting of ##STR7##
Claim 6
Dependent Claim
76 words
A hair rinse composition according to claim 1, wherein the alkali salt of the decomposition product obtained by oxidation of keratin material or the derivative at a thiol group of the decomposition product obtained by reduction of keratin material is formed in a system by adding to the hair rinse composition the oxidation decomposition product of keratin material or the derivative at the thiol group of the reduction decomposition product of keratin material and an alkali.
Claim 7
Dependent Claim
41 words
A hair rinse composition according to any of claims 1, 2, 4 and 5, wherein the amounts of the cationic surface active agent and the decomposition derivative of keratin material are, respectively, 0.01-10 wt% and 0.1-5 wt% of the total composition.
Claim 8
Dependent Claim
18 words
A hair rinse composition according to claim 6, wherein the amounts are, respectively, 0.2-5 wt% and 0.1-5 wt%.
