The present invention provides a method and use of incorporating water-soluble or water-dispersible polymer(s), stabilized in an invert (water-in-oil) emulsion, into an oil continuous metalworking emulsifiable concentrate, which is then diluted with water to form an end use oil-in-water emulsion. According to the present invention, the invert polymer emulsion (A) is added to the metalworking emulsifiable concentrate (B) to embed at least one water-soluble or water-dispersible polymer into the metalworking emulsifiable concentrate, to form a stable, emulsifiable concentrate (C). The stable, emulsifiable concentrate (C) is then diluted with water to form an end use oil-in-water emulsion (D) causing the water-soluble or water-dispersible polymer in the end use emulsion to impart antimist performance. |
