1. A non-irritating foamable composition in an aerosol container comprising:

  • a carrier composition comprising;

    a. about 80% to about 99.6% by weight of the carrier composition of a solvent comprising water and a water miscible organic solvent;

    b. about 0.1% to about 5% by weight of the carrier composition of at least one foam adjuvant, wherein the at least one foam adjuvant is selected from a fatty alcohol, a fatty acid, a hydroxy fatty acid, and mixtures thereof;

    c. about 0.1% to about 5% by weight of the carrier composition of at least one surface active agent; and

    a liquefied or compressed gas propellant wherein the weight ratio of the propellant to the carrier composition is about 3;

    97 to about 25;

    75;

    wherein upon release from the container, 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.
