Instantaneously self-foaming liquid cleansing composition

A non-pressurized, non-compartmentalized dispenser of a deformable barrier material, the dispenser comprising a vessel formed with:

• 1) a deformable peripheral wall having an open neck;
• 2) a positive shut off valve member comprising a tubular valve stem having a central dispensation passage for dispensing a liquid;
• and
• 3) an actuating means which is biased towards the deformable barrier material of the dispenser;
• and wherein said dispenser contains a composition comprising a stable, aqueous, self-foaming, self-leveling liquid consisting essentially of a mixture of:
• (a) an effective amount of water to form a stable, aqueous, self-foaming, self-leveling liquid when mixed with components (b) and (c);
• (b) from about 0.1 to about 60 percent by weight of a surfactant wherein said surfactant is an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, or a mixture of at least two of anionic, nonionic, amphoteric, and cationic surfactants, said surfactant selected to form a stable, self-foaming, self-leveling liquid when mixed with components (a) and (c);
• and
• (c) from about 1 to about 20 percent by weight of of a dual purpose pressure agent selected to form an integral part of the composition and selected to volatilize upon spreading the composition with a single motion, wherein said dual purpose pressure agent is
• (A) neopentane,
• (B) a mixture of at least one gaseous hydrocarbon having 4 carbon atoms and a nonvolatile silicone oil, or
• (C) a mixture of at least one gaseous hydrocarbon having 4 carbon atoms and at least one liquid hydrocarbon selected from iso-pentane, pentane, 2,3-dimethylbutane, hexane, iso-hexane, and mineral oil, said dual purpose pressure agent selected to form a stable, self-foaming, self-leveling liquid when mixed with components capable of providing said liquid composition with
• (i) a self-foaming property upon dispensation as a liquid from said container, and
• (ii) a vapor pressure of from about 0.1 psig to about 17 psig above atmospheric pressure at a temperature of about 22.degree. C. in said container, said dual purpose pressure agent selected to form a stable, aqueous, self-foaming, self-leveling liquid when mixed with components (a) and (b);
• said resultant stable, aqueous, self-foaming, self-leveling liquid having a vapor pressure of from about 0.1 to about 17 psig in excess of atmospheric pressure at a temperature of 22.degree. C. in said container, said resultant stable, aqueous, self-foaming, self-leveling liquid adapted to be dispensed in the form of a liquid from said container, whereby the liquid foams instantaneously on spreading.
