***°€εΐΟΗ In the research laboratory the unusual is commonplace. Chemists in industry are con tinually called upon to conjure up some new magic emulsion to meet a certain prob lem or special condition. New solutions to these problems are pos sible with cationic emulsions made from the Armeens and Armacs — Armour's high molecular weight aliphatic amines and amine acetate salts. Among their unique characteristics are : The pH of these emulsions is usually on the acid side but may go as high as 7. Alkaline conditions break the emulsion.
These cationic emulsions have the ability to exhaust the oil phase of the emulsion onto such materials as metallic oxides, cell ulose or siliceous surfaces. Calcium, magnesium, aluminum and other metallic ions have little effect upon the stability of these emulsions. Compati bility is determined by the. type of anion— acetates are well tolerated, chlorides toler ated, sulfates not tolerated. Write t o d a y for our new booklet, "The Armeens a n d Armacs as Cationic Emulsifiers." I n f o r m a t i o n covers properties, use and typical formulations.
