Surfactant-free water-free foamable compositions, breakable foams and gels and their uses

A method of treating rosacea, consisting of administering a surfactant free foam composition, obtained from a foamable composition dispensed from a container, to a subject in need thereof, wherein the foamable composition consists of:

• i) a carrier consisting of:
• a) about 60% to about 95% by weight of the carrier of a hydrophobic solvent;
• b) 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;
• c) 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 a mixture of any two or more thereof;
• and
• d) one active agent, wherein the one active agent is minocycline or a salt thereof;
• and
• ii) a liquefied or compressed gas propellant;
• wherein the foamable composition comprises 15% or less of petrolatum by weight of the carrier;
• wherein the foamable composition is essentially waterless;
• wherein the foamable composition is free of polymeric agent;
• wherein, upon dispensing, the foamable composition forms a foam;
• and
• wherein the subject in need thereof has rosacea.
