Abstract

The present invention relates to a composition comprising isosorbide monooleate, a first surfactant selected from the group consisting of an alkyl glycoside having a weight average of the number of C-atoms in the alkyl chain of more than 11, cocoamidopropyl betaine and mixtures thereof, a second surfactant which is an alkyl glycoside having a weight average of the number of C-atoms in the alkyl chain of less than 11 and water. Furthermore it relates to a process for making this composition and to a cosmetic formulation, comprising this composition.

First claim

The invention claimed is:

1. A composition comprising
15-35% by weight isosorbide monooleate,
10-30% by weight of a first surfactant selected from the group consisting of an alkyl glycoside having a weight average of the number of C-atoms in the alkyl chain of more than 11, cocoamidopropyl betaine, and mixtures thereof,
10-30% by weight of a second surfactant which is an alkyl glycoside having a weight average of the number of C-atoms in the alkyl chain of less than 11,
optionally an acid in an amount such that a pH value of the composition is 3 to 7,
0-5% by weight further cosmetically acceptable ingredients, and
balance water to 100% by weight.

2. The composition according to claim 1 comprising
20-30% by weight, isosorbide monooleate.

3. The composition according to claim 1 comprising
15-25% by weight of a first surfactant selected from the group consisting of an alkyl glycoside having a weight average of the number of C-atoms in the alkyl chain of more than 11, cocoamidopropyl betaine, and mixtures thereof.

4. The composition according to claim 1 comprising
15-25% by weight of the second surfactant.

5. The composition according to claim 1 , wherein the first surfactant is an alkyl glycoside having a weight average of the number of C-atoms of more than 11.

6. The composition according to claim 1 , wherein the first surfactant is cocoamidopropyl betaine.

7. The composition according to claim 1 comprising an organic acid in an amount such that the pH value of the composition is 3 to 7.

8. The composition according to claim 1 comprising
23-28% by weight, isosorbide monooleate,
17-22% by weight of an alkyl glycoside having a weight average of the number of C-atoms in the alkyl chain of more than 11,
17-22% by weight, of an alkyl glycoside having a weight average of the number of C-atoms in the alkyl chain of less than 11,
an organic acid in an amount such that the pH value of the composition is 3 to 7,
balance water to 100% by weight.

9. The composition according to claim 1 , wherein the composition is not a microemulsion.

10. The composition according to claim 1 , wherein the composition comprises less than 5% by weight of an oil.

11. The composition according to claim 1 , wherein the isosorbide monooleate is a mixture comprising pure isosorbide monooleate in an amount of 65-95% by weight.

12. The composition according to claim 1 , wherein the alkyl glycosides present are alkyl glucosides, wherein the degree of oligomerization (number average) of the glucose moiety is between 1 and 2.

13. The composition according to claim 1 , wherein the composition has a viscosity of between 1000 and 10000 mPas (determined with a Brookfield RVT viscometer, spindle 5, 20 rpm, at 20° C.).

14. A process for making the composition according to claim 1 , wherein this process comprises
mixing the isosorbide monooleate, the first surfactant, the second surfactant, optionally the acid, optionally the further cosmetically acceptable ingredients and water, at a temperature of more than 20° C.

15. A cosmetic formulation, comprising
the composition according to claim 1 , in an amount of 0.5 to 10% by weight,
and further cosmetically acceptable ingredients.

16. The composition according to claim 1 , wherein the first surfactant is an alkyl glycoside having a weight average of the number of C-atom of more than 12.

17. The composition according to claim 1 , wherein the second surfactant is an alkyl glycoside having a weight average of the number of C-atom of less than 10.

18. The composition according to claim 7 wherein the organic acid is selected from the group consisting of citric acid, lactic acid, and a mixture thereof.

19. The composition according to claim 11 , wherein the isosorbide monooleate is a mixture comprising pure isosorbide monooleate in an amount of 65-85% by weight.

20. The cosmetic formulation of claim 15 wherein the formulation is a shampoo or a bodywash formulation.
