Moisturizing Foam Containing Lanolin

A hydrating foamable composition comprising an emulsion, the emulsion comprising:

• i) a hydrating component comprising an emollient, a humectant, or a mixture thereof;
• ii) about 0.1% to about 5% of a surface-active agent by weight of the emulsion;
• iii) about 0.01% to about 5% by weight of the emulsion of at least one polymeric additive selected from the group consisting of a bioadhesive agent, a gelling agent, a film forming agent, a phase change agent, a water-soluble cellulose ether, a naturally-occurring polymeric material, and mixtures of two or more thereof;
• iv) water;
• and
• v) optionally at least one therapeutic agent;
• and
• a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the hydrating foamable composition;
• wherein upon release from a pressurized container the composition expands to form a foam that collapses upon application of shear force but does not immediately collapse upon exposure to skin temperature.

A hydrating foamable composition comprising an emulsion, the emulsion comprising:

• i) a hydrating component comprising a humectant;
• ii) about 0.1% to about 5% of a surface-active agent by weight of the emulsion;
• iii) about 0.01% to about 5% by weight of the emulsion of at least one polymeric additive selected from the group consisting of a bioadhesive agent, a gelling agent, a film forming agent, a phase change agent, a water-soluble cellulose ether, a naturally-occurring polymeric material, and mixtures of two or more thereof;
• iv) water;
• and
• v) optionally at least one therapeutic agent;
• and
• a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the hydrating foamable composition;
• wherein upon release from a pressurized container the composition expands to form a foam that collapses upon application of shear force but does not immediately collapse upon exposure to skin temperature.

A method of treating or alleviating insufficient hydration of skin, a body cavity or a mucosal surface, comprising:

• administering topically to skin, a body cavity or a mucosal surface a foam that collapses upon application of shear force but does not immediately collapse upon exposure to skin temperature, wherein the foam is obtained by releasing from a pressurized container a foamable composition comprising an emulsion comprising:
• i) a hydrating component comprising an emollient, a humectant, or mixture thereof;
• ii) about 0.1% to about 5% of a non-ionic surface-active agent by weight of the emulsion;
• iii) about 0.01% to about 5% by weight of the emulsion of at least one polymeric additive selected from the group consisting of a bioadhesive agent, a gelling agent, a film forming agent, a phase change agent, a water-soluble cellulose ether, a naturally-occurring polymeric material, and mixtures of two or more thereof;
• and
• iv) water;
• and
• a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the hydrating foamable composition;
• wherein the non-ionic surface-active agent comprises a combination of at least one non-ionic surfactant having HLB of less than 9 and at least one non-ionic surfactant having HLB of equal or more than 9, wherein the ratio between the at least one non-ionic surfactant having HLB of less than 9 and the at least one non-ionic surfactant having HLB of equal or more than 9, is between 1:8 and 8:1.
