Abstract

The present disclosure relates to a cosmetic composition containing an oil mixture in a total amount of from about 40 to about 99% by weight, in relation to the total amount of the cosmetic composition, without taking into consideration any propellant possibly provided, wherein the oil mixture of at least two selected esters, at least one linear polydimethylsiloxane with a viscosity of from about 1 to less than about 20 cSt, also PPG-14 butyl ether, wherein cyclic polydimethylsiloxanes are contained in a total amount, in relation to the total amount of the cosmetic composition, of from 0 to about 0.4% by weight, and wherein PPG-14 butyl ether and linear polydimethylsiloxanes are contained in selected ratios by weight to one another.

First claim

The invention claimed is:

a) at least two esters comprising 2-ethylhexyl palmitate and isopropyl myristate, wherein the ratio by weight of the 2-ethylhexyl palmitate to the isopropyl myristate lies in the range of from about 1 to about 3;
b) at least one linear polydimethylsiloxane, wherein the linear polydimethylsiloxane, at 25° C. and a pressure of 1013 mbar, has a kinematic viscosity of from about 1 to less than about 20 cSt; and
c) PPG-14 butyl ether;
wherein the oil mixture is free of any cyclic polydimethylsiloxanes,
wherein the total amount of the at least two esters, in relation to the total amount of the oil mixture, is from about 45 to about 70% by weight, and
wherein the ratio by weight of PPG-14 butyl ether to the total amount of the at least one linear polydimethylsiloxane lies in the range of from about 1.2 to about 2.4.

2. The cosmetic composition according to claim 1 , wherein the at least one linear polydimethylsiloxane, at 25° C. and a pressure of 1013 mbar, has a kinematic viscosity of from about 1 cSt to less than about 15 cSt.

3. The cosmetic composition according to claim 1 , wherein the total amount of the at least one linear polydimethylsiloxane, in relation to the total amount of the oil mixture, is from about 5 to about 25% by weight.

4. The cosmetic composition according to claim 1 , wherein the total amount of PPG-14 butyl ether, in relation to the total amount of the oil mixture, is from about 15 to about 30% by weight.

5. The cosmetic composition according to claim 1 , wherein the oil mixture comprises:
PPG-14 butyl ether in an amount of from about 15 to about 30% by weight, and
wherein the at least one linear polydimethylsiloxane, at 25° C. and a pressure of 1013 mbar, has a kinematic viscosity of from about 1 to less than about 15 cSt, and the total amount of the at least one linear polydimethylsiloxane is from about 5 to about 25% by weight,
wherein the amounts relate to the weight of the oil mixture.

6. The cosmetic composition according to claim 1 , wherein the oil mixture is contained in an amount of from about 50 to about 85% by weight, in relation to the total amount of the cosmetic composition.

7. The cosmetic composition according to claim 1 , wherein the total amount of water, in relation to the total amount of the cosmetic composition, is from 0 to about 5% by weight.

8. The cosmetic composition according to claim 1 , wherein the cosmetic composition additionally comprises at least one antiperspirant active substance, in relation to the total amount of the cosmetic composition, of from about 10 to about 40% by weight.

9. The cosmetic composition according to claim 1 , wherein it is present in the form of an antiperspirant composition.

10. The cosmetic composition according to claim 1 , wherein the total amount of the at least two esters, in relation to the total amount of the oil mixture, is from about 50 to about 65% by weight.

11. The cosmetic composition according to claim 1 , wherein the ratio by weight of PPG-14 butyl ether to the total amount of the at least one linear polydimethylsiloxane lies in the range of from about 1.3 to about 2.2.

12. The cosmetic composition according to claim 3 , wherein the total amount of the at least one linear polydimethylsiloxane, in relation to the total amount of the oil mixture, is from about 10 to about 17% by weight.

13. The cosmetic composition according to claim 4 , wherein the total amount of PPG-14 butyl ether, in relation to the total amount of the oil mixture, is from about 20 to about 25% by weight.

14. A cosmetic composition comprising an oil mixture in a total amount of from about 40 to about 99% by weight, in relation to the total amount of the cosmetic composition, without taking into consideration any propellant possibly provided, wherein the oil mixture comprises:
a) at least two esters in a total amount of from about 50 to about 65% by weight comprising 2-ethylhexyl palmitate and isopropyl myristate wherein the ratio by weight of the 2-ethylhexyl palmitate to the isopropyl myristate lies in the range of from about 1 to about 3;
b) at least one linear polydimethylsiloxane in a total amount of from about 10 to about 17% by weight, wherein the linear polydimethylsiloxane or a mixture of two or more linear polydimethylsiloxanes, at 25° C. and a pressure of 1013 mbar, has a kinematic viscosity of from about 1 to less than about 15 cSt; and
c) PPG-14 butyl ether in an amount of from about 20 to about 25% by weight wherein the ratio by weight of PPG-14 butyl ether to the total amount of all linear polydimethylsiloxanes lies in the range of from about 1.5 to about 2.0;
wherein the cosmetic composition is free of cyclic polydimethylsiloxane, and
wherein the amounts relate to the weight of the oil mixture.

15. The cosmetic composition according to claim 14 , wherein the cosmetic composition additionally comprises at least one antiperspirant active substance, in relation to the total amount of the cosmetic composition, of from about 10 to about 40% by weight.

16. The cosmetic composition according to claim 14 , wherein it is present in the form of an antiperspirant composition.
