Abstract

The present disclosure concerns a deodorant emulsion for an aerosol spray which is free from aluminum salts and ethanol, comprising: at least one emulsifier, at least one salt, water, at least one silicone oil and at least one further oil, and a deodorant aerosol spray product comprising a pressure or pump spray container with spray head, the filling of which comprises the deodorant emulsion and optionally a propellant and/or further solvent, and a use of the deodorant aerosol spray product for deodorizing human skin.

First claim

The invention claimed is:

1. A deodorant emulsion suitable for an aerosol spray comprising:
at least one emulsifier;
at least one salt;
a water/alcohol mixture, wherein the alcohol is selected from propanol, isopropanol, propanediol-1,3, dipropylene glycol, propanediol-1,2, or a combination thereof;
at least one silicone oil; and
at least one further oil;

wherein the deodorant emulsion is free from aluminum salts and ethanol.

2. A deodorant emulsion according to claim 1 , comprising:
from about 1.0% to about 4.5% by weight of the at least one emulsifier,
from about 0.5% to about 7.0% by weight of the at least one salt,
from about 3.0% to about 17.0% by weight of the at least one silicone oil, and
from about 6.0% to about 17.0% by weight of the at least one further oil,
all based on the total weight of the deodorant emulsion.

3. A deodorant emulsion according to claim 2 , further comprising at least one perfume oil in a concentration of from about 2.0% to about 8.0% by weight, based on the total weight of the deodorant emulsion.

4. A deodorant emulsion according to claim 1 , comprising:
from about 2.0% to about 4.0% by weight of the at least one emulsifier,
from about 1.0% to about 5.0% by weight of the at least one salt,
from about 5.0% to about 15.0% by weight of the at least one silicone oil, and
from about 11.0% to about 15.0% by weight of the at least one further oil,
all based on the total weight of the deodorant emulsion.

5. A deodorant emulsion according to claim 4 , further comprising at least one perfume oil in a concentration of from about 3.0% to about 7.0% by weight, based on the total weight of the deodorant emulsion.

6. A deodorant emulsion according to claim 1 , further comprising at least one perfume oil in a concentration of from about 1.0% to about 10.0% by weight, based on the total weight of the deodorant emulsion.

7. A deodorant emulsion according to claim 1 , wherein the deodorant emulsion further comprises at least one deodorant active ingredient in a concentration of 0.1% to 50.0% by weight, based on the total weight of the deodorant emulsion.

8. A deodorant emulsion according to claim 1 , wherein the deodorant emulsion is free of decamethylcyclopentasiloxane.

9. A deodorant emulsion according to claim 1 , wherein the water/alcohol mixture is included in an amount of from about 60% to about 99% by weight based on the total weight of the deodorant emulsion.

10. A deodorant emulsion according to claim 1 , wherein:
the at least one emulsifier comprises a silicone emulsifier; and
the at least one salt is a magnesium sulfate;
the at least one silicone oil is selected from linear silicone oils or cyclic silicone oils.

11. A deodorant emulsion according to claim 1 , wherein:
the at least one emulsifier is an alkoxylated fatty acid alcohol,
the at least one salt is a magnesium sulfate;
the at least one silicone oil is selected from polydimethylsiloxane or cyclopentasiloxane.

12. A deodorant aerosol spray product comprising a pressure or pump spray container with spray head, the deodorant emulsion according to claim 1 , wherein the deodorant emulsion optionally comprises a propellant and/or a further solvent.

13. A method comprising applying the deodorant aerosol spray product according to claim 12 to human skin.

14. A deodorant emulsion according to claim 1 , comprising:
from about 2.0% to about 4.0% by weight of the at least one emulsifier,
from about 1.0% to about 5.0% by weight, of the at least one salt;
from about 5.0% to about 15.0% by weight of the at least one silicone oil; and
from about 11.0% to about 15.0% by weight of the at least one further oil;
wherein all amounts are based on the total weight of the deodorant emulsion.

15. A deodorant emulsion according to claim 1 , wherein the alcohol is propanediol-1,2.

16. A deodorant emulsion according to claim 1 , wherein the water/alcohol mixture is included in an amount of from about 65% to about 96% by weight, based on the total weight of the deodorant emulsion.

17. A deodorant emulsion comprising:
triethyl citrate and phenoxyethanol;
dimethicone;
a dispersion of silicone polyether in a low-viscosity, non-volatile dimethicone liquid;
a water/propanediol-1,2 mixture; and
magnesium sulfate;
wherein the deodorant emulsion is free from aluminum salts and ethanol.

18. A deodorant emulsion according to claim 17 , comprising:
the triethyl citrate and phenoxyethanol in a combined amount of from about from about 1.0% to about 30.0% by weight;
the dimethicone in an amount of from about 5.0% to about 15.0% by weight;
the dispersion of silicone polyether in a low-viscosity, non-volatile dimethicone liquid as a 25% dispersion of silicone polyether in a low-viscosity, non-volatile dimethicone liquid with the INCI name Dimethicone (and) PEG/PPG-18/18 Dimethicone in an amount of from about 2.0% to about 4.0% by weight;
