Abstract

The present disclosure relates to an antiperspirant cosmetic agent containing:
a) from about 0.5 to about 7.0% by weight of at least one copolymer formed from the monomers
i) N-tert-octylacrylamide ii) acrylic acid iii) tert.-butylaminoethyl methacrylate iv) and optionally further monomers
b) from about 40 to about 75% by weight of oil that is liquid at about 20° C. and about 1.013 hPa wherein the antiperspirant cosmetic agent does not contain any aluminium-containing compounds, use thereof, and methods using an agent of this kind.

First claim

The invention claimed is:

1. An antiperspirant cosmetic agent comprising:
a) from about 0.5 to about 10% by weight of at least one copolymer formed from at least the monomers:
i) N-tert-octylacrylamide,
ii) acrylic acid, and
iii) tert.-butylaminoethyl methacrylate; and

b) from about 25 to about 70% by weight of an oil that is in liquid state at about 20° C. and about 1.013 hPa,
wherein the antiperspirant cosmetic agent does not contain any aluminium-containing compounds, and wherein the oil comprises cyclopentasiloxane.

2. The antiperspirant cosmetic agent according to claim 1 , wherein the agent comprises, as copolymer a), at least one copolymer formed from at least the monomers:
i) N-tert-octylacrylamide,
ii) acrylic acid,
iii) tert.-butylaminoethyl methacrylate,
iv) methyl methacrylate, and
v) hydroxypropyl methacrylate.

3. The antiperspirant cosmetic agent according to claim 1 , wherein the copolymer a), in relation to the total weight of the agent, is included in an amount of from about 1.0 to about 10% by weight.

4. The antiperspirant cosmetic agent according to claim 1 , wherein the oil, in relation to the total weight of the agent, is included in an amount of from about 35 to about 55% by weight.

5. The antiperspirant cosmetic agent according to claim 1 further comprising a hydrophilic organic solvent.

6. A cosmetic preparation comprising:
i) the antiperspirant cosmetic agent according to claim 1 ; and
ii) a propellant.

7. A cosmetic product comprising:
i) the cosmetic preparation according to claim 6 ; and
ii) a dispensing device having a spray valve.

8. A non-therapeutic cosmetic method for preventing and/or reducing body odor, the method comprising the steps of applying an antiperspirant cosmetic agent to a user's skin and leaving the antiperspirant cosmetic agent on the skin for at least about 1 hour, wherein the antiperspirant cosmetic agent comprises:
a) from about 0.5 to about 10% by weight of at least one copolymer formed from at least the monomers:
i) N-tert-octylacrylamide,
ii) acrylic acid, and
iii) tert.-butylaminoethyl methacrylate; and

b) from about 25 to about 70% by weight of an oil that is in liquid state at about 20° C. and about 1.013 hPa,
wherein the antiperspirant cosmetic agent does not contain any aluminium-containing compounds, and wherein the oil comprises cyclopentasiloxane.

9. The antiperspirant cosmetic agent according to claim 1 , wherein the copolymer a), in relation to the total weight of the agent, is included in an amount of from about 3.0 to about 7.0% by weight.

10. The antiperspirant cosmetic agent according to claim 5 , wherein the hydrophilic organic solvent, in relation to the total weight of the agent, is included in an amount of from about 10 to about 60% by weight.

11. The antiperspirant cosmetic agent according to claim 5 , wherein the hydrophilic organic solvent, in relation to the total weight of the agent, is included in an amount of from about 15 to about 50% by weight.

12. The antiperspirant cosmetic agent according to claim 5 , wherein the hydrophilic organic solvent, in relation to the total weight of the agent, is included in an amount of from about 20 to about 40% by weight.

13. The method according to claim 8 comprising the step of leaving the antiperspirant cosmetic agent on the skin for at least about 2 hours.

14. The method according to claim 8 comprising the step of leaving the antiperspirant cosmetic agent on the skin for at least about 4 hours.

15. The method according to claim 8 comprising the step of leaving the antiperspirant cosmetic agent on the skin for at least about 6 hours.

16. The method of claim 8 , wherein the antiperspirant cosmetic agent further comprises a hydrophilic organic solvent.

17. The method of claim 8 , wherein the step of applying the antiperspirant cosmetic agent to the skin comprises applying the antiperspirant cosmetic agent to the user's armpit skin.

18. An antiperspirant cosmetic agent comprising:
a) from about 1.0 to about 10% by weight of at least one copolymer formed from at least the monomers:
i) N-tert-octylacrylamide,
ii) acrylic acid, and
iii) tert.-butylaminoethyl methacrylate;

b) from about 35 to about 55% by weight of an oil that is in liquid state at about 20° C. and about 1.013 hPa; and
c) from about 15 to about 50% by weight of a hydrophilic organic solvent, wherein the antiperspirant cosmetic agent does not contain any aluminium-containing compounds, and wherein the oil comprises cyclopentasiloxane.

19. The antiperspirant cosmetic agent according to claim 18 , wherein the copolymer a), in relation to the total weight of the agent, is included in an amount of from about 3.0 to about 7.0% by weight.
