46. A waterless carrier for use with one or more active agents comprising a) a modulating agent; b) a polyol; c) a surface active agent; d) a foam adjuvant; and e) a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the composition wherein at least one active agent if present is susceptible to one or more of reaction, breakdown, ionization or oxidation; wherein the modulating agent comprises an effective amount of one or more agents that are capable of impeding said destabilization and or are capable of stabilizing the active agent primarily by modulating or adjusting the artificial pH of the carrier such that the modulating agent is capable of producing in the waterless carrier an artificial pH or an artificial pH buffering effect at about a pH or pH range in which the stability of at least one active agent is improved when compared to its stability in the carrier without the modulating agent and or by chelating a metal ion such that the modulating agent is capable of reducing in the waterless carrier the availability of metal ions so the stability of at least one active agent is improved when compared to its stability in the carrier without the modulating agent; and wherein the composition is stored in an aerosol container and upon release expands to form a breakable foam.
