ABSTRACT:
Disclosed are emulsions which do not rust or corrode steel surfaces and further do not contain rust or corrosion inhibiting additives. The emulsions encompassed in this invention are produced using mechanical or emulsion polymerization emulsification methods. The mechanically produced emulsions must contain at least one cationic surfactant containing an anion which has a parent acid with a pK.sub.a of 3 or greater. The emulsion produced using emulsion polymerization methods are produced from (A) at least one cationic surfactant containing an anion which has a parent acid with a pK.sub.a of 3 or greater; (B) a basic or strongly basic catalyst; and (C) a catalyst neutralizer selected from acids having a pK.sub.a of 3 or greater and having the capability of neutralizing the catalyst. These emulsions are useful in applications where they might come in contact with steel surfaces.
