Use of an extract from the
An active composition for treating skin having a protein-containing extract from a Vigna aconitifolia plant.
1. A topical cosmetic and/or dermopharmaceutical composition for improving signs of aging in skin, improving skin quality, treating inflamed skin or treating damaged skin in humans comprising:
an effective amount of a) a protein containing extract from Vigna aconitifolia plant obtained by extracting seeds of the Vigna aconitifolia plant with water or an aqueous solution at 30° C. to 70° C. to obtain a solvent extract and a residue, separating the solvent extract from the residue, heating the solvent extract at 70° C. to 90° C., adjusting the solvent extract to pH 5-7, and centrifuging and filtering the solvent extract to obtain the protein containing extract and b) at least one polyol.
2. The composition of claim 1 , wherein the protein containing extract contains at least one soluble protein fraction extracted from seeds of the Vigna aconitifolia plant.
3. The composition of claim 1 , wherein the protein containing extract is present in the composition in an amount of from about 0.001 to 30% by weight, based on the weight of the composition.
4. The composition of claim 1 , wherein the protein containing extract is present in the composition in an amount of from about 0.1 to 20% by weight, based on the weight of the composition.
5. The composition of claim 1 , wherein the protein containing extract is present in the composition in an amount of from about 0.2 to 10% by weight, based on the weight of the composition.
6. A method of improving signs of aging in skin, improving skin quality, treating inflamed skin or treating damaged skin in a person in need thereof comprising:
topically applying to skin of the person a composition comprising a therapeutically effective amount of a) a protein containing extract from a Vigna aconitifolia plant produced by a process consisting essentially of extracting seeds of the Vigna aconitifolia plant with water or an aqueous solution at 30° C. to 70° C. to obtain a solvent extract and a residue, separating the solvent extract from the residue, heating the solvent extract at 70° C. to 90° C., adjusting the solvent extract to pH 5-7, and centrifuging and filtering the solvent extract to obtain the protein containing extract and b) a polyol.
7. The method of claim 6 , wherein the protein containing extract contains at least one soluble protein fraction extracted from seeds of the Vigna aconitifolia plant.
8. The method of claim 6 , wherein the protein containing extract is present in the composition in an amount of from about 0.001 to 30% by weight, based on the weight of the composition.
9. The method of claim 6 , wherein the protein containing extract is present in the composition in an amount of from about 0.1 to 20% by weight, based on the weight of the composition.
10. The method of claim 6 , wherein the protein containing extract is present in the composition in an amount of from about 0.2 to 10% by weight, based on the weight of the composition.
11. The composition of claim 1 , wherein the composition comprises from about 1 to about 50% by weight of the polyol.
12. The composition of claim 11 , wherein the polyol comprises glycerol.
13. The composition of claim 1 , wherein the composition comprises:
a) from about 40 to about 70% by weight of the protein containing extract of the Vigna aconitifolia plant, and
b) from about 1 to about 50% by weight of the polyol.
14. A topical cosmetic and/or dermopharmaceutical composition for improving signs of aging in skin, improving skin quality, treating inflamed skin or treating damaged skin in humans comprising:
an effective amount of a) a protein containing extract from Vigna aconitifolia plant obtained by extracting seeds of the Vigna aconitifolia plant with water or an aqueous solution at 30° C. to 70° C. to obtain a solvent extract and a residue, separating the solvent extract from the residue, heating the solvent extract at 70° C. to 90° C., adjusting the solvent extract to pH 5-7, and centrifuging and filtering the solvent extract to obtain the protein containing extract and b) a cosmetically and/or dermopharmaceutically acceptable auxiliary.
15. The composition of claim 14 , wherein the protein containing extract is present in the composition in an amount of from about 0.001 to 30% by weight, based on the weight of the composition.
16. The composition of claim 1 , wherein the seeds are extracted at 40° C. to 50° C. and the pH of the solvent extract is adjusted to pH 5.5 to 6.5.
17. The composition of claim 1 , wherein the at least one polyol includes glycerol.
18. The composition of claim 17 , further comprising an antioxidant and a preservative.
19. The composition of claim 15 , wherein the composition comprises from 50 to 65% by weight of the protein containing extract and from 10 to 40% by weight of the polyols.
