1. A method of treating or alleviating a dermal or mucosal condition selected from the group consisting of wounds, burns, infections, ulcers and combinations thereof, comprisinga. releasing an effective amount of non-irritating foamable composition from an aerosol container comprising:
- i. about 0.1% to about 5% by weight of iodine;
ii. about 80% to about 99.6% by weight of at least one solvent;
iii. about 0.1% to about 5% by weight of at least one foam adjuvant,wherein the at least one foam adjuvant is selected from a fatty alcohol, a fatty acid and a hydroxy fatty acid and mixtures thereof;
iv. about 0.1% to about 5% by weight of at least one surface active agent; and
v. a liquefied or compressed gas propellant wherein the weight ratio of the propellant to the remainder of the composition is about 3;
97 to about 25;
75, andwherein upon release, the foamable composition forms a thermally stable breakable foam having a specific gravity of between about 0.02 g/mL and about 0.35 g/mL;
b. applying the breakable foam to an afflicted surface having a dermatological or mucosal disorder; and
c. collapsing the breakable foam by applying a gentle rub, wherein the collapsed foam is absorbed into the afflicted surface without chaffing of the surface.

Abstract
The present invention is related to a foamable composition of matter comprising iodine, water, a foam adjuvant, a surface-active agent and a gelling agent. This foamable composition, which may be provided in a propellant free foaming device, or alternatively may further comprise a propellant, evolves into foam, which is effective in the topical treatment and prevention of various skin disorders.
