1. 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.
