Non Surfactant Hydro-Alcoholic Foamable Compositions, Breakable Foams And Their Uses

A foamable composition comprising:

• a) about 15% to about 60% by weight of a short chain alcohol;
• b) a cellulose based polymer;
• c) about 0.1% to about 15% by weight of at least one fatty alcohol;
• d) a hydrophilic solvent;
• and
• e) at least one active agent;
• and
• f) a liquefied or compressed gas propellant at a concentration of about 3% to about 30% by weight of the total foamable composition,
• wherein the percent by weight is based on the weight of foamable composition other than propellant;
• wherein the foamable composition comprises 0.4% or less by weight of a surfactant;
• wherein the ratio range of the foamable carrier composition to propellant is from about 100:3 to about 100:30;
• and
• wherein upon dispensing the foamable composition forms a foam having a collapse time about or more than 60 seconds at 36° C.

A surfactant free foamable composition comprising:

• 1) about 15% to about 60% by weight of a short chain alcohol;
• 2) about 0.1% to about 5% by weight of a cellulose based polymer;
• 3) about 1% to about 15% by weight of at least one fatty alcohol or at least one fatty acid or a combination thereof;
• 4) about 2% to about 50% by weight of a hydrophilic solvent;
• 5) a liquefied or compressed gas propellant;
• 6) about 0.1% to about 5% by weight of an active agent;
• and
• 7) optionally a pH modifying agent and or a chelating agent;
• wherein the percent by weight is based on the weight of foamable composition other than propellant;
• and
• wherein the ratio of composition other than propellant to propellant ranges from about 100:3 to about 100:30.
