Abstract

The present application describes an antioxidant complex having a synergistic effect between its ingredients. Said mixture comprises: a) vitamin E and/or derivatives thereof; b) green tea extract and/or derivatives thereof; and c) cacao extract. Examples of cosmetic and pharmaceutical compositions comprising said antioxidant complex and a physiologically acceptable carrier are also described. The antioxidant complex of the present invention, as well as the aforementioned compositions, aid in preventing and protecting against cell and skin damages resulting from the action of free radicals, and also provide DNA, protein and cell membrane protection.

Claims (34)

1. An antioxidant complex having a synergistic antioxidant effect consisting essentially of:

a) from 1 μg/ml to 20000 μg/ml of Vitamin E;

b) from 10 μg/ml to 1000 μg/ml of green tea extract; and

c) from 10 μg/ml to 1000 μg/ml of Theobroma cacao extract,

wherein all the amounts are based on the total weight of the antioxidant complex.

2. The antioxidant complex according to claim 1 , wherein

a) the amount of Vitamin E is from 10 μg/ml to 200 μg/ml;

b) the amount of green tree extract is from 10 μg/ml to 100 μg/ml; and

c) the amount of Theobroma cacao extract is from 10 μg/ml to 100 μg/ml,

wherein all the amounts are based on the total weight of the antioxidant complex.

3. The antioxidant complex according to claim 1 , wherein said Vitamin E is tocopherol or tocopherol acetate.

4. The antioxidant complex according to claim 1 , wherein said green tea extract is a mixture of polyphenols, including catechins.

5. The antioxidant complex according to claim 1 , wherein said Theobroma cacao extract is rich in catechins and xanthines.

6. The antioxidant complex according to claim 1 , wherein

a) the Vitamin E is tocopherol acetate which is present in an amount of 10 μg/ml;

b) the green tea extract is a mixture of polyphenols, including catechins, and the green tea extract is present in an amount of 10 μg/ml; and

c) the Theobroma cacao extract is rich in catechins and xanthines, and the Theobroma cacao extract is present in amount of 10 μg/ml,

wherein all the amounts are based on the total weight of the antioxidant complex.

7. An antioxidant complex having a synergistic antioxidant effect consisting essentially of

a) from 1 μg/ml to 20000 μg/ml of Vitamin E;

b) from 10 μg/ml to 1000 μg/ml of green tea extract; and

c) from 10 μg/ml to 1000 μg/mlof Theobroma cacao extract, wherein all the amounts are based on the total weight of the antioxidant complex, and at least one additional antioxidant selected from the group consisting of butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), and tert-butylhydroguinone (TBHQ).

8. A cosmetic composition consisting essentially of the antioxidant complex of claim 1 ; and a cosmetically acceptable carrier.

9. The cosmetic composition according to claim 8 , wherein the amount of antioxidant complex ranges from 0.003% to 3.000% by weight, based on the total weight of the composition.

10. A pharmaceutical composition consisting essentially of:

a) the antioxidant complex of claim 1 ; and

b) a pharmaceutically acceptable carrier.

11. The pharmaceutical composition according to claim 10 , wherein the amount of antioxidant complex ranges from 0.003% to 3.000% by weight, based on the total weight of the composition.

12. A method of manufacturing a cosmetic composition consisting essentially of the steps of:

forming a cosmetic composition consisting essentially of the antioxidant composition of claim 1 , wherein said cosmetic composition combats molecular and morphological damages from lipoperoxidation, DNA oxidation and protein oxidation reactions, combating skin aging, combating damages caused by the sun and by adverse conditions including pollution, stress, and wind.

13. A method of manufacturing a pharmaceutical composition consisting essentially of the steps of:

forming a pharmaceutical composition consisting essentially of the antioxidant composition of claim 1 , wherein said pharmaceutical composition combats molecular and morphological damages from lipoperoxidation, DNA oxidation and protein oxidation reactions, combating skin aging, combating damages caused by the sun and by adverse conditions including pollution, stress, and wind.

14. A method for treating cell and skin damage consisting essentially of treating a patient in need thereof with a cosmetic composition comprising the antioxidant complex of claim 1 .

15. The method of claim 14 , wherein the cell or skin damage is associated with one or more of molecular and morphological damages from lipoperoxidation, DNA oxidation and protein oxidation reactions, combating skin aging, combating damages caused by the sun and by adverse conditions such as pollution, stress, and wind exposure.
