Abstract

Provided, among other things, is a method of treating skin and soft tissue wounds, ulcers, burns, various types of dermatoses, inflammatory conditions of the mucosa, and the like comprising: periodically applying to the wound, inflammatory condition of mucosal tissues, or dermatoses, over a course of days an effective amount of water based formulation (comprising: 0.5 to 5 wt % of an emollient comprising silicone oil, 2 to 10 wt % of fatty acid, humectant(s), emulsifying agent(s), and polymer(s)), wherein the formulation is formulated as a spray, cream, lotion, milk or foam-former.

Claims (50)

1. A water-based topical composition consisting of:

one or more carbomers;

one or more emollients selected from the group consisting of: dimethicone and petrolatum;

one or more C 12 -C 22 fatty acids;

one or more hydrophilic polymers selected from the group consisting of: polyvinyl pyrrolidone, polyethylene glycol, starch, cellulose, methyl cellulose, and hydroxymethylcellulose;

one or more humectants selected from the group consisting of: glycerol, propylene glycol, polydextrose, and lactic acid;

one or more emulsifying agents selected from the group consisting of: Tween 80 and polysorbate 20

one or more titrants selected from the group consisting of: trolamine, sodium hydroxide, and sodium citrate;

one or more preservatives selected from the group consisting of: ethylparaben, methylparaben, propylparaben, butylparaben, isobutylparaben, benzalkonium chloride, imidurea, and phenoxyethanol;

water; and

optionally one or more propellants selected from the group consisting of propane, butane, isobutene, hydrofluorocarbon, and chlorofluorocarbon.

2. The water-based composition of claim 1 , wherein the emollient is dimethicone.

3. The water-based composition of claim 1 , wherein the hydrophilic polymer is polyvinyl pyrrolidone.

4. The water-based composition of claim 1 , wherein the humectants are glycerol and propylene glycol.

5. The water-based composition of claim 1 , wherein the emulsifying agent is polysorbate 20.

6. The water-based topical composition of claim 1 , wherein the composition is formulated as a spray, cream, lotion, milk, or foam.

7. A water-based composition consisting of:

a carbomer;

one or more C 12 -C 22 fatty acids;

polyvinyl pyrrolidone;

propylene glycol;

glycerol;

dimethicone;

one or more titrants selected from the group consisting of trolamine and sodium hydroxide;

polysorbate 20;

one or more preservatives selected from the group consisting of methylparaben, ethylparaben, propylparaben, and phenoxyethanol;

water; and

optionally one or more propellants selected from the group consisting of propane, butane, isobutene, hydrofluorocarbon, and chlorofluorocarbon.

8. The water-based composition of claim 7 , wherein the one or more titrants is included in an amount to provide a pH of 6-9.

9. The water-based composition of claim 7 consisting of:

a carbomer;

5.0-7.0 wt. % stearic acid;

1.5-2.5 wt. % polyvinyl pyrrolidone;

5.0-6.5 wt. % propylene glycol;

1.0-2.5 wt. % glycerol;

0.5-5.0 wt. % dimethicone;

1.0-2.0 wt. % the one or more preservatives;

the one or more titrants;

water; and

optionally one or more propellants selected from the group consisting of propane, butane, isobutene, hydrofluorocarbon, and chlorofluorocarbon,

wherein the one or more titrants are provided in an amount sufficient to bring the composition to a pH of 6-9.

10. A method of treating dermatoses comprising:

applying the water based topical formulation of claim 1 to a skin area affected with dermatoses and covering with an occlusive patch;

wherein the water-based topical formulation is formulated as a spray, cream, lotion, milk, or foam-former.

11. The method of claim 10 , wherein the step of applying is performed two or three times daily.

12. The method of claim 10 , wherein the water-based topical formulation is applied to the skin area at 1 to 5 mg/cm 2 .

13. The composition of claim 1 , wherein the C 12 -C 22 fatty acids is stearic acid.

14. The composition of claim 1 , wherein the preservatives are ethylparaben, methylparaben, propylparaben, and phenoxyethanol.

15. The composition of claim 7 , wherein when the composition is formulated as a spray, cream, lotion, milk, or a foam.
