[Alkali resistance changes from use of water-in-oil- and oil-in-water emulsions]. 1983

H Jakob, and B Ummenhofer

Metal workers who up to 4 h prior to the alkali resistance (AR) test had applied different O/W-emulsions revealed a better mean AR on the forearms than those who had used W/O-emulsions or no protective skin ointments at all. Similar test results were achieved in 9 metal workers tested in a right-left comparison under standardized external conditions as in more than 300 workers of various industries. By a right-left comparison of an O/W- and W/O-emulsion with 14 students it was shown that all subjects with a low pre-test AR revealed an increased AR after the application of the ointment. Proved differences in AR-reactivity related to occupation and skin constitution of the subject tested are considered to be due to differences in the hydration rate of the horny layer.

D008669	Metallurgy	The science, art, or technology dealing with processes involved in the separation of metals from their ores, the technique of making or compounding the alloys, the techniques of working or heat-treating metals, and the mining of metals. It includes industrial metallurgy as well as metallurgical techniques employed in the preparation and working of metals used in dentistry, with special reference to orthodontic and prosthodontic appliances.

D004655	Emulsions	Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.	Emulsion
