Abstract
A substantially surface active agent-free foamable composition which includes short-chain alcohol, water, polymer, fatty alcohol or fatty acid or a combination of fatty alcohol and fatty acid and propellant. A substantially surface active agent-free foamable composition which includes, water, polymer, fatty alcohol or fatty acid and propellant. A method of treatment using a substantially surface active agent-free foamable compositions.
Claims49
A foamable composition comprising:
- a) a short chain alcohol;
- b) water;
- c) a foaming booster comprising:
- i) about 0.1% to about 5% by weight of a polymer;
- and
- ii) at least one fatty alcohol or at least one fatty acid or a combination thereof;
- and
- d) a liquefied or compressed gas propellant,
- wherein the composition is free of surfactant;
- wherein the percent by weight is based on the weight of foamable composition other than propellant;
- wherein the ratio of composition other than propellant to propellant ranges from about 100:3 to about 100:30;
- wherein the foamable composition is transparent;
- and
- wherein upon dispensing the foamable composition a foam is obtained having a collapse time at 36° C. of about or more than 60 seconds.
