Aerosol shaving foams

As mentioned above, the aerosol shave foam has been replaced with the more popular aerosol post-forming gel. The latter is more difficult to produce, since one has to produce a dear gel with the right rheological characteristics for discharge from the aerosol container, with good spreading on the surface of the skin. The foam should then be produced by vaporisation of a low-boding liquid such as isobutene or isopentene.

The aerosol container has enjoyed commercial success ia a wide variety of product categories. Insecticide aerosols were iatroduced ia the late 1940s. Additional commodities, including shave foams, hair sprays, antiperspirants, deodorants, paints, spray starch, colognes, perfumes, whipped cream, and automotive products, followed ia the 1950s. Mediciaal metered-dose aerosol products have also been developed for use ia the treatment of asthma, migraine headaches, and angiaa.

Aerosol-delivered shaving foam must be dense and tight and made of very small bubbles it has to retain its consistency when spread over the skin, neither becoming runny nor sliding from the cheek. Moreover, lather has to be rinsed easily from the razor without leaving sticky residues.

Emulsions. Aerosol emulsions (qv) may be oil in water (o/w), such as shaving creams, or water in oil (w/o), such as air fresheners and pohshes. These aerosols consist of active ingredients, an aqueous or nonaqueous vehicle, a surfactant, and a propellant, and can be emitted as a foam or as a spray. 

Chlorofluorocarbon Alternatives. There still is no completely satisfactory propellant for use in the aerosol method of foam production. Chloroflu-orocarbons, still widely used, are harmful 10 atmospheric ozone and low molecular weight hydrocarbons, now popular, e g., in producing shaving cream, are explosive and promote the greenhouse effect.
