...Isserlyn Creme jar lists 20 ingredients, most of them common chemicals and none of them particularly costly. Six of these ingredients-decyl oleate, lanolin oil, propylene glycol, isostearic acid, acetylated lanolin alcohol and ceteareth-5-are moisturizers and emollients. These relieve dryness and protect the skin by softening, conditioning and lubricating it. Triethanolamine, stearic acid, glyceryl stearate, magnesium aluminum silicate and PEG-75 lanolin oil are emulsifiers that enable the other ingredients to mix and form a smooth lotion. Three of the ingredients are pigments, which give color to the skin when the cream goes on. They are titanium dioxide...
Died. George Oliver Curme Jr., 87, pioneering industrial chemist; in Oak Bluffs, Mass. In 1914, Iowa-born Curme began synthesizing a wide variety of chemicals from hydrocarbons. The chemicals-which included industrial solvents, ethyl alcohol, acetylene for welding, ethylene glycol for antifreeze, and synthetic rubber-spawned entire new industries. In 1944 Union Carbide-which profitably developed his major discoveries-named him vice president in charge of chemical research...
Better protection is given the observatory's sensitive equipment. The 88-in. telescope, for example, is shielded from the distorting effects of temperature variations by a complex cooling system; glycol antifreeze solutions similar to those used in radiators of cars circulate through walls and floors to keep temperatures stable whenever observations are made. On the other hand, some heat is provided in the Mauna Kea's control center-not for the comfort of the hardy astronomers, but to warm the delicate circuitry of the observatory's computer...
Golden Tube. The target of the chromatographic detective work performed by the bomb sniffer is the vapor from a chemical called ethylene glycol dinitrate (EGDN), one of the principal components of emissions given off by dynamite. With the aid of a small internal fan, the detector samples air in the vicinity of a suspect object and passes the vapors over a modern equivalent of Tsvett's limestone-a rough gold-plated copper surface that has a special affinity for EGDN. As the molecules adhere to it, their concentration increases. The special surface is then heated...
