A word about Emcol Extraordinary. That's the word for Witco's Emcol surfactants. Because nearly all of them were formulated for out-of-theordinary problems that customers asked us to solve. After 30 years of solving them, it's no wonder you find us with such a wide range of extraordinary Emcols. For instance, our Emcol 14: It was a pioneer emulsifier. The first surfactant which af-
forded to formulators an economical means of producing stable, non-foaming emulsions with minimum corrosive activity for use in aerosols. Consider our polyalkoxylated quaternaries: They combine an unusually useful combination of properties: (1) function well in both water and oil; (2) have excellent emolliency; (3) are antistats; (4) have high molecular weight for substantive effect,
And (5) they're economical. Take our Emcol E-607: This is a quaternary ammonium compound that combines germicidal properties with low skin irritation tendency. For a compound of this type, E-607's excellentdetergency properties are a unique feature. Now take your particular surfactant problem: Need more wetting? better pesticide emulsification? antistatic effects? emulsifiers for
your aerosols? Whatever the problem, bring it around. And the more extraordinary, the better. Because our specialty is taking on problems that ordinary surfactants can't solve. Then developing Emcols that solve them. Extraordinarily well. Call (212-826-1000) or write Witco Chemical, Organics Division, Dept. AJ-11, 277 Park Ave., N. Y., N. Y. 10017.
