Abstract
Non-pressurized shaving compositions are described that provide a warm/hot sensation during use as the result of an exothermic redox reaction. The compositions are post-foaming via nascent gas release in situ due to the generation of carbon dioxide. The carbon dioxide induced foam is maintained for several minutes after the compositions are dispensed, whereby the compositions are capable of providing both a warm sensation and sustained lather, a balance which heretofore has been a significant challenge.
