BALANCE MAKES THE
DIFFERENCE... ... in solving problems that involve surface active agents. The perfect balance of many components is often required to create an emulsifier to assure optimum performance. Proper balance also means savings through more economical emulsifier levels. Witco's Emcol surface active agents offer the chemist the broadest latitude in solving problems involving emulsification, dispersion, and other colloidal effects. The Emcol line includes anionic, nonionic, and cationic products. For more information on these versatile materials, send for your copy of Witco's brochure describing the "Emcol Surface Active A g e n t s " . Write to Technical Service Department E-110.
.1 Two immiscible phases separate immediately when a hydrocarbon solvent containing no emulsifier is poured into water.
2 The same solvent containing 3fy< of a poorly balanced blend of anionic-nonionic emuLsifiers forms only a fair emulsion in water.
