Abstract: A water-dispersible cooling and lubricating composition effective for use as a metal working fluid or a metal removal fluid. The composition comprises an oil and water emulsion prepared from a pre-emulsion concentrate having a high concentration of crude, degummed vegetable oil which can be combined with esters of such vegetable oil. The metal working fluid composition of the present invention is prepared by mixing the crude vegetable oil with alkyl esters as an antigumming agent, a corrosion inhibitor, a surfactant, a saponifier, a buffer, and a preservative to form a pre-emulsion concentrate. In a preferred embodiment of the invention, the pre-emulsion concentrate further comprises a fragrance. To form the desired metal working fluid composition of the present invention, the pre-emulsion concentrate is mixed with water to form a stable metal working fluid composition of the present invention.

Abstract: An improved sealing composition for concrete which is effective for sealing a concrete surface to prevent the passage of water therethrough comprising a non-refined vegetable oil such as coconut oil, corn oil, cottonseed oil, palm oil, rapeseed (canola) oil, soya oil, sunflower oil, and mixtures thereof; an emulsifier effective for providing a oil-in-water emulsion, and water. A preferred composition comprises a pre-emulsion concentrate comprising essentially of about 95% to about 50% by weight of a non-refined vegetable oil, about 5% to about 50% of an emulsifier comprising a 3 mole ethylene oxide adduct of C12 and C14 alcohols; and water.
