Abstract
Abstract A shaving preparation is provided which has a sub-atmospheric vapor pressure at ambient temperature and which generates a lather when applied to the skin. The composition comprises a water-insoluble volatile organic liquid having a vapor pressure substantially below atmospheric pressure, an aqueous soap solution and a surface active agent which together promote the volatilization of the organic liquid, thereby generating a lather as well as reducing the tendency of the volatile organic liquid to cause smarting of the skin. The compositions of this invention are capable of being packaged in a collapsible tube without premature expansion in the tube during storage, shipment and use.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
208 words
A shaving preparation having a sub-atmospheric vapor pressure at ambient temperatures and which generates lather in a practical period of time when applied to the skin consisting essentially of (1) an aqueous soap solution; (2) a surface active agent; and, (3) a volatile water-insoluble organic liquid having a vapor pressure substantially below atmospheric pressure, and capable of having its volatilization promoted by the aqueous soap solution and surface active agent, said aqueous soap solution and surface active agents being of such nature and in such amounts that when said compositions is applied to the skin the volatilization of the volatile organic liquid is promoted to the extent that a lather is generated in a practical period of time while reducing the tendency of the volatile organic liquid to cause smarting of the skin, said aqueous solution containing the surface active agent in an amount of about 1 to 10% by weight of the total composition and a water-insoluble volatile organic liquid in an amount of 1 to 10% by weight of the total composition, said aqueous solution containing soap in an amount from about 5 to 25% by weight; the water of the aqeuous solution being present in an amount to give 100% by weight for the composition.
Claim 2
Dependent Claim
208 words
