Abstract

Cosmetic emulsions are disclosed that can remain stable even with relatively high salt based cosmetic astringent content. In one aspect, an emulsion can include a water phase including water and a rheology modifier including Microcrystalline Cellulose and Cellulose Gum. The emulsion can also include an oil phase comprising Steareth-2 and Glyceryl Stearate and an emulsifier selected from the group consisting of: Steareth-20, Steareth-21, and combinations thereof. The emulsion can include a salt based cosmetic astringent providing at least about 1.0% of the emulsion by weight.

Claims (26)

1. An emulsion comprising:

a. a water phase comprising water and a rheology modifier comprising Microcrystalline Cellulose and Cellulose Gum;

b. an oil phase comprising Steareth-2 and Glyceryl Stearate and an emulsifier selected from the group consisting of: Steareth-20, Steareth-21, and combinations thereof; and

c. a salt based cosmetic astringent in an amount of at least about 1.0% by total weight of the emulsion,

wherein the salt based cosmetic astringent is selected from the group consisting of: Ammonium and Potassium Alum, Aluminum Triphosphate, Aluminum Glycinate and Aluminum Phenolsulfate, Aldioxa, Aluminum Stearate, Aluminum Sulfate, Aluminum Citrate, Sodium aluminum Phosphate, Sodium Alum, Sodium Aluminum Chlorohydroxy Lactate, Calcium Lactate, Calcium Chloride, Zinc Acetate, Zinc Chloride, Zinc Sulfate, Zinc Lactate, and Zinc Phenolsulfonate.

2. The emulsion of claim 1 , wherein the emulsion comprises the rheology modifier in an amount from about 0.01% to about 2.0% by total weight of the emulsion.

3. The emulsion of claim 1 , wherein the emulsion comprises the rheology modifier in an amount from about 0.01% to about 5.0% by total weight of the emulsion.

4. The emulsion of claim 1 , wherein the emulsion comprises the emulsifier in an amount from about 0.01% to about 10.0% by total weight of the emulsion.

5. The emulsion of claim 1 , wherein the emulsion comprises the emulsifier in an amount from about 0.01% to about 5.0% by total weight of the emulsion.

6. The emulsion of claim 1 , wherein the emulsion comprises the salt based cosmetic astringent in an amount of at least about 3.0% by total weight of the emulsion.

7. The emulsion of claim 1 , wherein the emulsion comprises the salt based cosmetic astringent in an amount of at least about 5.0% by total weight of the emulsion.

8. The emulsion of claim 1 , wherein the emulsion comprises the Glyceryl Stearate in an amount of at least about 3.0% by total weight of the emulsion.

9. The emulsion of claim 1 , wherein the emulsion comprises the Glyceryl Stearate in an amount of at least about 4.0% by total weight of the emulsion.

10. The emulsion of claim 1 , wherein the emulsion is sprayable.

11. An emulsion comprising:

a. a water phase comprising water and a rheology modifier comprising Microcrystalline Cellulose, Cellulose Gum, and Gum Arabic;

b. an oil phase comprising Steareth-2 and an emulsifier selected from the group consisting of: Steareth-20, Steareth-21, and combinations thereof; and

c. a salt based cosmetic astringent in an amount of at least about 1.0% by total weight of the emulsion,

wherein the salt based cosmetic astringent is selected from the group consisting of: Ammonium and Potassium Alum, Aluminum Triphosphate, Aluminum Glycinate and Aluminum Phenolsulfate, Aldioxa, Aluminum Stearate, Aluminum Sulfate, Aluminum Citrate, Sodium aluminum Phosphate, Sodium Alum, Sodium Aluminum Chlorohydroxy Lactate, Calcium Lactate, Calcium Chloride, Zinc Acetate, Zinc Chloride, Zinc Sulfate, Zinc Lactate, and Zinc Phenolsulfonate.

12. The emulsion of claim 11 , wherein the emulsion comprises the rheology modifier in an amount from about 0.01% to about 2.0% by total weight of the emulsion.

13. The emulsion of claim 11 , wherein the emulsion comprises the rheology modifier in an amount from about 0.01% to about 5.0% by total weight of the emulsion.

14. The emulsion of claim 11 , wherein the emulsion comprises the emulsifier in an amount from about 0.01% to about 10.0% by total weight of the emulsion.

15. The emulsion of claim 11 , wherein the emulsion comprises the emulsifier in an amount from about 0.01% to about 5.0% by total weight of the emulsion.

16. The emulsion of claim 11 , wherein the emulsion comprises the salt based cosmetic astringent in an amount of at least about 3.0% by total weight of the emulsion.

17. The emulsion of claim 11 , wherein the emulsion comprises the salt based cosmetic astringent in an amount of at least about 5.0% by total weight of the emulsion.

18. The emulsion of claim 11 , wherein the emulsion is sprayable.
