1. A self-foaming composition comprising:
a. 20 wt % to less than 70 wt % polyol; and
b. 1.5 wt % to 9.5 wt % of total surfactant wherein 50 wt % or more of the total surfactant is a surfactant defined by a Vh/Icao value of 0.1 to 0.25, wherein Vh is a volume of hydrophobic groups of a micellar core, Ic is a length of the hydrophobic group and ao is a cross-sectional area occupied by a hydrophilic group at a micelle-solution interface; wherein the total surfactant is selected from the group consisting of sultaines, betaines, alkyl taurates, alkyl glutamates and glycinates, alkyl isethionate, alkyl glucosides, alkyl amphoacetate and mixtures thereof;
wherein viscosity of the composition is 25 cP or less, measured at 25° C.;
wherein the composition comprises no more than 0 to 0.5 wt % propellant gel or gas.
