Abstract

Multi-functional base emulsions that can be used to form a variety of cosmetic compositions are disclosed. In one aspect, a cosmetic emulsion can include a water phase including about 10% to about 67.5% water by total weight of the cosmetic emulsion. The cosmetic emulsion can also include an oil phase that includes (a) stearalkonium hectorite, and (b) a silicone alkyl polyether selected from the group consisting of: PEG/PPG-18/18 dimethicone, PEG/PPG-20/15 dimethicone, and Lauryl PEG/PPG-18/18 dimethicone.

Claims (19)

1. A cosmetic emulsion comprising:

a water phase comprising an amount of water, the amount of water being less than 65.5% by total weight of the cosmetic emulsion; and

an oil phase comprising:

(a) stearalkonium hectorite; and

(b) a silicone alkyl polyether selected from the group consisting of: PEG/PPG-18/18 dimethicone, PEG/PPG-20/15 dimethicone, and Lauryl PEG/PPG-18/18 dimethicone; wherein a total concentration of the stearkalkonium hectorite and the silicone alkyl polyether is 20% or less by total weight of the cosmetic emulsion; wherein a ratio between the stearalkonium hectorite to the silicone alkyl polyether ranges from 1:3 to 3:1;

wherein the cosmetic emulsion is sprayable, and wherein the amount of water and the ratio between the stearalkonium hectorite to the silicone alkyl polyether results in the cosmetic emulsion being stable.

2. The cosmetic emulsion of claim 1 , wherein the silicone alkyl polyether is Lauryl PEG/PPG-18/18 dimethicone.

3. The cosmetic emulsion of claim 1 , wherein the oil phase further comprises a silicone oil.

4. The cosmetic emulsion of claim 1 , wherein the ratio between the stearalkonium hectorite to the silicone alkyl polyether is 1:1.

5. The cosmetic emulsion of claim 4 , wherein the silicone alkyl polyether is Lauryl PEG/PPG-18/18 dimethicone.

6. A cosmetic emulsion in a form of a lotion or cream, the cosmetic emulsion comprising:

a water phase comprising an amount of water, the amount of water being at least 65.5% (by total weight of the emulsion); and

an oil phase comprising:

(a) stearalkonium hectorite; and

(b) a silicone alkyl polyether selected from the group consisting of: PEG/PPG-18/18 dimethicone, PEG/PPG-20/15 dimethicone, and Lauryl PEG/PPG-18/18 dimethicone; wherein a total concentration of the stearkalkonium hectorite and the silicone alkyl polyether is 20% or less by total weight of the cosmetic emulsion; wherein a ratio between the stearalkonium hectorite and the silicone alkyl polyether ranges from 1:3 to 3:1;

and wherein the amount of water and the ratio between the stearalkonium hectorite to the silicone alkyl polyether results in the cosmetic emulsion being stable.

7. The cosmetic emulsion of claim 6 , wherein the silicone alkyl polyether is Lauryl PEG/PPG-18/18 dimethicone.

8. The cosmetic emulsion of claim 6 , wherein the ratio of the silicone alkyl polyether to the stearalkonium hectorite is 2:1.

9. The cosmetic emulsion of claim 8 , wherein the silicone alkyl polyether is Lauryl PEG/PPG-18/18 dimethicone.
