Abstract
Abstract A pressurized foaming shaving composition includes with an anionic surface active foaming agent and a foam stabilizer, in an aqueous medium, a mixture of higher fatty acid triglycerides of acids of 16 to 18 carbon atoms, which acids include stearic, oleic and palmitic acids, the proportion of saturated fatty acid groups to unsaturated fatty acid groups being about 1 or more, plus an organic liquefied gas propellant to pressurize the composition. The product made is of satisfactory foam characteristics, including body, and gives comfortable, clean shaves which leave the skin feeling soft and conditioned. The shaving composition is especially useful for the shaving of body areas, such as the neck, upper legs and axillae and of areas such as the axillae to which preparations which can have irritant effects, such as antiperspirants and deodorants, are sometimes subsequently applied.
