Abstract: The invention provides personal care products that include, within a pressurized can, a personal care formulation, a propellant, and a sorbant that has formed a gel with at least a portion of the propellant. The invention also provides methods of manufacturing personal care products.

Abstract: A process for preparing a submicron antiperspirant adduct. The process begins by dissolving a mixture of an aluminum-containing salt and a steric stabilizer in a solvent. The antiperspirant salt is then precipitated into the steric stabilizer. The resulting adduct of submicron size can be dispersed into a cosmetic carrier or otherwise processed.

Abstract: A hydrophilic sebum collecting device including a strip of hydrophilic open celled microporous polymeric film.Also provided is a method for the quantification of sebum in a patch of skin by applying a hydrophilic open celled microporous polymeric film to the patch of skin such that the film is retained in sebum collecting contact therewith. The film is retained in sebum collecting contact for a period of about 5 to 30 seconds and at a predetermined pressure. The film is eventually removed from the patch of skin and placed over a scaled background such that the amount of sebum collected by the film can be determined by comparison with the scaled background.

Abstract: A liquefied gas apparatus, in particular a gas lighter for smokers, is disclosed, utilizing a vaporizer-pressure reducer assembly including a pressure reducing device situated generally within a vaporizer. All solid materials with which the assembly is in contact have a thermal conductivity in the range 0.3 to 5 kcal/m/h/.degree. C.

Abstract: A chewable tooth cleaning device comprising from 2.45 to 9.0 cm.sup.3 of substantially closed-cell compressible polymeric foam having a substantially skin-free surface adapted to scrub exposed tooth surfaces. In particular, the polymeric foam has about 12 to 50 cells per linear centimeter, a water absorptivity of less than 1.0 mg/cm.sup.3 after being submerged in water for 24 hours, a tensile strength of at least 3.4.times.10.sup.5 Pa, a compressive strength of at least 5.5.times.10.sup.4 Pa at 10% deflection, and at least 8.3.times.10.sup.4 Pa at 25% deflection, a tear strength of at least 1.38.times.10.sup.5 Pa, and is sufficiently resilient to return to at least 90% of its uncompressed height almost immediately after being compressed to 10% of its uncompressed height.

Abstract: A process for storage of a liquefied gas on an adsorbant support in a chamber provided with at least one discharge orifice for the distribution of the gas in gaseous form into an environment at a pressure lower then the storage pressure. The adsorbant support is constituted of hollow capillary fibres, natural or synthetic, such as kapok fibers. The hollow capillary fibers have an inner diameter between about 10 to 35.mu. and a wall thickness about 0.2 to 3.mu.. The actual volume of the fibers represents about 11% of the storage chamber.
