Cosmetic and/or dermopharmaceutical preparations containing native proteins from the plant
A cosmetic and/or dermopharmaceutical composition containing an extract of native proteins derived from the plant Argania spinosa.
1. A composition selected from the group consisting of cosmetic compositions and dermapharmaceutical compositions, comprising a mixture containing native proteins from the plant Argania spinosa wherein said native proteins have a molecular weight of at least about 10,000 Da, and wherein the mixture containing the native proteins is present in the composition in an amount of about 0.03 to 5% by weight, based on a dry weight of the composition.
2. The composition of claim 1 wherein the mixture containing the native proteins is present in the composition in an amount of about 0.03 to 0.6% by weight, based on a dry weight of the composition.
3. A process for both protecting, and enhancing the appearance of at least one member selected from the group consisting of, skin and hair comprising contacting the at least one member with a composition comprising a mixture containing an effective amount of native proteins from the plant Argania spinosa , wherein, the native proteins have a molecular weight of at least about 10,000 Da.
4. The process of claim 3 wherein the mixture containing native proteins is obtained from seeds and/or defatted seeds of the plant Argania spinosa.
5. The process of claim 3 wherein the mixture containing native proteins is obtained by extraction of at least a portion of the plant Argania spinosa with an aqueous medium at a pH of less than or equal to 12 and a temperature of from 20° C. to 100° C.
6. The process of claim 3 wherein the native proteins have a molecular weight of from 10,000 Da to about 250,000 Da.
7. The process of claim 3 wherein the native proteins comprise a native protein having a molecular weight of from 10,000 to 18,000 Da.
8. The process of claim 3 wherein the native proteins comprise native proteins having a molecular weight of from 170,000 to 250,000 Da.
9. The process of claim 3 wherein the mixture comprising native proteins has an active substance content of about 20 to 85% by weight, based on a dry weight of the mixture.
10. The process of claim 3 wherein the mixture comprising native proteins is present in the composition, in an amount of about 0.01 to 25% by weight, based on a weight of the composition.
11. The process of claim 3 wherein the mixture comprising native proteins is present in the composition in an amount of about 0.03 to 5% by weight, based on a weight of the composition.
12. The process of claim 3 wherein the mixture comprising native proteins is present in the composition in an amount of about 0.03 to 0.6% by weight, based on a weight of the composition.
