1. A surfactant free, flowable foamable composition comprising:

  • a carrier comprising;

    a) about 60% to about 95% by weight of the carrier of a hydrophobic solvent, wherein the hydrophobic solvent is an oil; and

    b) an oleaginous foamer complex comprising;

    (1) about 0.1% to about 20% by weight of the carrier of at least one fatty alcohol,wherein the fatty alcohol has a carbon chain length of 14 to 22 carbons; and

    (2) about 0.1% to about 20% by weight of the carrier of at least one fatty acid, at least one wax, at least one shea butter, or mixtures of two or more thereof, wherein the fatty acid has a carbon chain length of 12 to 28 carbons, and the wax is selected from the group consisting of a beeswax, a hydrogenated castor oil, a paraffin wax, a wax that is solid at room temperature, and mixtures of two or more thereof; and

    a liquefied or compressed gas propellant;

    wherein the composition comprises 15% or less than 15% of petrolatum by weight of the carrier;

    wherein the composition is essentially waterless;

    wherein the composition is free of polymeric agent; and

    wherein the ratio of carrier to propellant is from about 100;

    3 to about 100;

    30; and

    wherein upon dispensing, the flowable foamable composition forms a breakable foam that breaks easily upon application of shear force.
