Abstract
Abstract A hair setting composition is described which comprises at least one of decomposition products obtained by oxidation of keratin materials and derivatives at a thiol group of decomposition products obtained by reduction of keratin materials, and at least one of alkanolamines and basic amino acids. The member is dissolved in a polar solvent in an amount of 0.01 to 10 wt. % of the composition. The base is contained in a weight ratio to the member of 0.02 to 0.7:1.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
A hair setting composition comprising as the effective ingredient from 0.01 to 10 wt% of the decomposition product obtained by the oxidation of a keratin material selected from the group consisting of animal hair, human hair, wool fibers, feather, claw, horn and hoof and a basic material selected from the group consisting of 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, 2-amino-1-butanol, triisopropanolamine, diisopropanolamine, monoisoopropanolamine, triethanolamine, diethanolamine, monoethanolamine, lysine, arginine, histidine and hydroxylysine in an amount of from 0.02 to 0.7 to one part of the effective ingredient, the balance being a polar solvent selected from the group consisting of water, ethyl alcohol and propyl alcohol; said composition being soluble in said polar solvent.
