Abstract
Official abstract text for this publication.
The subject of the application is protein hydrolyzates having specific amounts of the amino acids arginine and lysine, which demonstrate improved properties in hair treatment compositions and in cleansing compositions for skin and hair, and also enzymatic methods for the preparation thereof, and the cosmetic compositions comprising same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A protein hydrolyzate consisting of free and peptide-bound amino acids, wherein 8.0-25 wt % of the amino acids are arginine and 6.0-25 wt % of the amino acids are lysine. 2. The protein hydrolyzate according to claim 1 , wherein 5.0 to 25 wt % of the amino acids are lysine. 3. The protein hydrolyzate according to claim 1 , wherein 8.2 to 25% of the amino acids are arginine. 4. The protein hydrolyzate according to claim 1 , wherein 8.2 to 8.5 wt % of the amino acids are arginine and 6.0 to 6.5 wt % of the amino acids are lysine. 5. A method for preparing a protein hydrolyzate according to claim 1 , wherein a mixture of soy and rice proteins in a weight ratio of 2:1 to 4:1 is enzymatically hydrolyzed in the presence of at least one endopeptidase. 6. The method for preparing a protein hydrolyzate according to claim 5 , wherein a mixture of soy and rice proteins in a weight ratio of 2:1 to 4:1 is enzymatically hydrolyzed in the presence of at least one endopeptidase and subsequently hydrolyzed once again in the presence of an exopeptidase. 7. A conditioner in a hair treatment composition, comprising the protein hydrolyzate of claim 1 . 8. A method for improving the internal hair structure of hair, comprising treating the hair with the protein hydrolyzate of claim 1 . 9. A cosmetic composition comprising the protein hydrolyzate according to claim 1 , wherein the hydrolyzate is present in an amount of 0.002 to 0.4 wt % based on the active substance content. 10. A cosmetic composition for hair treatment comprising the protein hydrolyzates according to claim 1 , wherein the composition additionally comprises cationic or pseudo-cationic surfactants or cationic polymers. 11. A cosmetic composition for cleansing skin and/or hair comprising the protein hydrolyzates according to claim 1 , wherein the composition additionally comprises anionic surfactants and amphoteric or zwitterionic surfactants.
