Here are two exciting new chemicals from A n s u l . H . A . has been effective in stabilizing chlorinated hydrocarbons, motor fuel, r u b b e r . . . as a non-staining a n t i - o x i d a n t and '— valuable intermediate. T h e sun-screening properties of D . M . B . offer possibilities as a weathering agent In paints, lacquers, plastics and in sun-tan lotions and creams. Its sweet-clover odor may suggest use in cosmetic formulations. W e will also be glad to send you our latest technical bulletins or samples of these promising chemicals.
