Abstract

Cosmetic or dermatological composition including, in a physiologically acceptable medium, a hydrophilised extract of peppermint stems and use of such a composition as an antioxidant in a cosmetic or dermatological composition.

First claim

The invention claimed is:

1. A peppermint extract (I) obtained by the extraction of peppermint stems with a mixture of hydroalcoholic solvents and esterification with glycerol, said peppermint extract (I) comprising at least a compound of formula (I):

2. A cosmetic or dermatological composition, comprising, in a physiologically acceptable medium, a peppermint extract (I) according to claim 1 .

3. The composition according to claim 2 , further comprising a peppermint extract (II) obtained by the extraction of stems with a mixture of hydroalcoholic solvents comprising at least a compound of formula (II):

4. The composition according to claim 3 , wherein the ratio by weight of the extracts (I)/(II) is between 0.5 and 2.

5. The composition according to claim 4 , wherein the ratio by weight of the extracts (I)/(II) is 1.

6. The composition according to claim 3 , wherein the hydroalcoholic extract (II) is obtained by alcohol extraction by means of a monohydric alcohol and/or a glycol.

7. The composition according to claim 3 , further comprising a peppermint extract (III) obtained by the extraction of peppermint stems with a mixture of hydroalcoholic solvents, and esterification with octyl alcohol, said peppermint extract (III) comprising at least one compound of formula (III):

8. The composition according to claim 7 , further comprising a mixture of extracts (I), (II) and (III), wherein the ratio by weight of the extracts (II)/(III) is between 0.5 and 1.5 and the ratio by weight of the extracts (I)/(II) is between 2 and 4.

9. The composition according to claim 7 , characterised in that the ratio by weight of the extracts (I)/(II)/(III) is 3/1/1.

10. The composition of claim 7 , wherein the mixture of hydroalcoholic solvents is an ethanol/water mixture.

11. The composition of claim 3 , wherein the mixture of hydroalcoholic solvents is an ethanol/water mixture.

12. The composition according to claim 3 , wherein the hydroalcoholic extract (II) is obtained by alcohol extraction by means of a monohydric alcohol and/or a glycol mixed with water.

13. The composition according to claim 1 , wherein the composition is suited to topical application.

14. The composition according to claim 1 , wherein said extract (I) or the mixture of extracts (I) and (II) represents a content ranging from 0.01% to 10% by weight, with respect to the total weight of the composition.

15. The composition of claim 14 , wherein the content ranges from 0.1% to 10% by weight.

16. The composition of claim 14 , wherein the content ranges from 1% to 5% by weight.

17. A cosmetic or dermatological composition comprising the peppermint extract (I) according to claim 1 .

18. The peppermint extract of claim 1 , wherein the mixture of hydroalcoholic solvents is an ethanol/water mixture.

19. The composition according to claim 1 , wherein said extract (I) or the mixture of extracts (I), (II), and (III) represents a content ranging from 0.01% to 10% by weight, in particular from 0.1% to 10% with respect to the total weight of the composition.
