Abstract

A self-foaming composition can include at least one perfluoro compound, at least one surfactant, and at least one fatty component. The composition, when released from a sealed vessel, forms a foam without the need to add any other components. The composition can include an active agent, e.g., for skin care, such as an anti-acne agent.

Claims

1. A self-foaming composition comprising:

at least one perfluoro compound;

at least one surfactant; and

at least one fatty component selected from a fatty alcohol and/or a fatty acid;

wherein the composition, when released from a sealed vessel, forms a foam.

2. The composition of claim 1, comprising from about 0.1% w/w to about 25% w/w of surfactant(s).

3. The composition of claim 2, wherein the surfactant(s) are selected from glycereth-18 ethylhexanoate, glycereth-18, sodium C14-16 olefin sulfonate, sodium cocoamphoacetate, cocamidopropyl hydroxysultaine, coco glucoside, and mixtures thereof.

4. The composition of claim 2, comprising from about 0.1% w/w to about 10% w/w of the fatty component.

5. The composition of claim 4, wherein the fatty component is selected from cetyl alcohol, coconut alcohol, oleyl alcohol, stearyl alcohol, arachidyl alcohol, batyl alcohol, behenyl alcohol, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, myristoleic acid, palmitoleic acid, oleic acid, linoleic acid, linolenic acid, arachadonic acid, and combinations thereof.

6. The composition of claim 5, comprising at least two fatty components.

7. The composition of claim 1, further comprising a skin care active agent.

8. The composition of claim 7, wherein the skin care active agent is selected from sulfur, colloidal sulfur, benzoyl peroxide, and salicylic acid, or a combination thereof.

9. The composition of claim 1, wherein the composition comprises:

water (40-60% w/w);

at least one of;

glycereth-18 ethylhexanoate (0-2.5% w/w), glycereth-18 (0-2.5% w/w), sodium C14-16 olefin sulfonate (5-15% w/w), sodium cocoamphoacetate (1-5% w/w), cocamidopropyl hydroxysultaine (0.1-1.5% w/w), and coco glucoside (2-8% w/w); and

at least one of;

coconut alcohol (2-8% w/w), behenyl alcohol (0.1-2.5% w/w), and stearyl alcohol (0.1-5% w/w).

10. The composition of claim 1, wherein the composition comprises Water (Aqua), Xanthan Gum, Acrylates Copolymer, Glycereth-18 Ethylhexanoate, Glycereth-18, Sodium C14-16 Olefin Sulfonate, Sodium Cocoamphoacetate, Cocamidopropyl Hydroxysultaine, Propanediol, Phenoxyethanol, Ethylhexylglycerin, Coco Glucoside, Coconut Alcohol, Behenyl Alcohol, Stearyl Alcohol, Ethylhexylglycerin, Phenoxyethanol, and colloidal sulfur.

11. The composition of claim 1, wherein the perfluoro compound is a perfluoro ether.

12. The composition of claim 1 in a sealed bag-on-valve container.

13. A method of making a self-foaming composition, comprising:

forming a composition by combining at least one perfluoro compound;

at least one surfactant; and

at least one fatty component selected from a fatty alcohol and/or a fatty acid; and

enclosing the composition in a sealed vessel;

wherein the composition, when released from the sealed vessel, forms a foam.

14. The method of claim 13, wherein the composition comprises from about 0.1% w/w to about 25% w/w of surfactant(s).

15. The method of claim 13, wherein the surfactant(s) are selected from glycereth-18 ethylhexanoate, glycereth-18, sodium C14-16 olefin sulfonate, sodium cocoamphoacetate, cocamidopropyl hydroxysultaine, coco glucoside, and mixtures thereof.

16. The method of claim 13, wherein the composition comprises from about 0.1% w/w to about 10% w/w of the fatty component.

17. The method of claim 16, wherein the fatty component is selected from cetyl alcohol, coconut alcohol, oleyl alcohol, stearyl alcohol, arachidyl alcohol, batyl alcohol, and behenyl alcohol, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, myristoleic acid, palmitoleic acid, oleic acid, linoleic acid, linolenic acid, arachadonic acid, and combinations thereof.

18. The method of claim 17, comprising at least two fatty components.

19. The method of claim 13, wherein the composition further comprises a skin care active agent.

20. The method of claim 19, wherein the a skin care active agent is selected from sulfur, colloidal sulfur, benzoyl peroxide, and salicylic acid, or a combination thereof.

21. The method of claim 13, wherein the composition comprises:

water (40-60% w/w);

at least one of;

glycereth-18 ethylhexanoate (0-2.5% w/w), glycereth-18 (0-2.5% w/w), sodium C14-16 olefin sulfonate (5-15% w/w), sodium cocoamphoacetate (1-5% w/w), cocamidopropyl hydroxysultaine (0.1-1.5% w/w), and coco glucoside (2-8% w/w); and

at least one of;

coconut alcohol (2-8% w/w), behenyl alcohol (0.1-2.5% w/w), and stearyl alcohol (0.1-5% w/w)

22. The method of claim 13, wherein the composition comprises Water (Aqua), Xanthan Gum, Acrylates Copolymer, Glycereth-18 Ethylhexanoate, Glycereth-18, Sodium C14-16 Olefin Sulfonate, Sodium Cocoamphoacetate, Cocamidopropyl Hydroxysultaine, Propanediol, Phenoxyethanol, Ethylhexylglycerin, Coco Glucoside, Coconut Alcohol, Behenyl Alcohol, Stearyl Alcohol, Ethylhexylglycerin, Phenoxyethanol and colloidal sulfur.
