Abstract
Abstract A pre-shampoo type hair treatment composition is described which comprises at least one decomposition derivative of keratin material selected from hydrolysates of keratin material, alkali salts of decomposition products obtained by oxidation of keratin material and alkali salts of derivatives at the thiol group of decomposition products obtained by reduction of keratin material, the at least one decomposition derivative having been dissolved or dispersed in suitable solvent.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
A pre-shampoo hair treatment composition which comprises (A) 0.5-5% by weight of at least one decomposition derivative of keratin material selected from the group consisting of (1) alkali salts of decomposition products obtained by oxidation of keratin material, and (2) alkali salts of derivatives at the thiol group of decomposition products obtained by reduction of keratin material, alone or in combination with a keratin product having only been subjected to hydrolysis, and (B) 0.1 to 5 wt% of at least one cationic polymer selected from the group consisting of diallyl quaternary ammonium salts, cationic celluloses, cationic starches and cationic vinyl polymers; in a polar solvent.
Claim 2
Dependent Claim
