The Next Step Beyond Cooperation—

SYNERGISM Cooperation paves the way for synergistic thinking—when minds, cooperating to get better results, "click" from the impact of idea meeting idea and e v o h t a result that is far greater than the sum total of the ideas expressed.

Where chemistry is concerned, synergistic thinking between buyer and seller uncovers new and better ways to make old products, new and superior formulas, entirely new products for n e w purposes.

A t l a s S p a n s a n d T w e e n s offer a fascinating chal lenge for synerg i s t i c thinking.

Atlas Spans and Tweens are new surface active agents, with an amazing range of accomplishment, modifications and combinations.

Some of the Atlas Spans, for example, can emulsify 250 times their weight of water in petrolatum—a great aid in the manufacture of low-oil content wirt?er-iri—oil emulsions. This extreme water-holding power constitutes a reserve against: "bleed­ing" and "sweating" of water-in-oil ointments, creams, pastes, jellies, cosmetics, and pharmaceuticals.

Spans and Tweens make water-in-oil or oil-in-water emulsions, of eitlier tlhe stable o r quick-breaking types . T h e y can easily be tailor-made to particular problems. The field of application of these emulsifiers has barely been scratched ! "What an opportunity for synergistic thinking in evolving new or better products!
