EMEMBER the days of the juicy steak? the dripping cuts of calf's liver? Few housewives then gave thought to what kept those juices where they belonged — inside the wrapping paper. And, perhaps you in turn, have given little thought to the problems of efficiently getting the waxes where they belong—and what the solution of those problems can mean t o you. For example,, when you emulsify different waxes on a large scale—in water of varying degrees of hardness—you need a versatile set of emulsifiers. That, of course, is what Atlas Spans and Tweens are. T h a t ' s why chemists use them so widely. Extraordinary stability in the presence of salts and other electrolytes is just one property of Atlas Spans and Tweens. They make water-in-
oil or oil-in-water emulsions—whatever is desired. They range from the completely water soluble to the completely oil soluble. They provide a wide range of compatibilities. Because of their chemical nature, an almost unlimited number of modifications and combinations is possible with them. Think of Spans and Tweens in relation to your own emulsifying,wetting, spreading or detergent problems. If technical help is needed, we'll be glad to give it. As a starter, write for a free copy of the 20 page booklet illustrated at the right.
