NOVELTY - A composition comprising high load carrying capabilities biodiesel metalworking fluids containing major proportion of biodiesel and minor proportion of extreme pressure additive, anti-wear additive, emulsifier, corrosion inhibitor and antioxidant is formed by: (A) adding sulfur/zinc salts of dithio-organophosphates anti-wear additive; (B) adding chlorine/phosphorus extreme pressure additive; (C) adding nonylphenol/alcohol ethoxylate; (D) adding sulfonate and amine based corrosion inhibitors; (E) adding antioxidant additives; and (F) adding biocides.    USE - As composition of biodiesel metalworking fluid (claimed), useful in many machining applications including turning, milling, broaching, drawing, tapping, drilling, grinding, and high speed cutting processes.    ADVANTAGE - The biodiesel metalworking fluid exhibits excellent cooling and load carrying capabilities even when diluted with 1-20 parts of water; when diluted with water turns milky-white and exhibits excellent anti-foam properties; are renewable, less environmentally hazardous and safer to human contact unlike the petroleum-based metalworking fluids; has a Timken OK Load of 105 kilograms ASTM-D-2509; and exhibits excellent lubricating, corrosion inhibition, anti-rancid and load carrying capability properties over conventional mineral based metalworking fluids. The metalworking fluids produced from biodiesel provide improvements in properties which are economic to manufacture. The metalworking fluids produced from biodiesel are manufactured through a simplified and reliable process using readily available, economical and non-hazardous raw materials with simplified equipment and production times.    DETAILED DESCRIPTION - A composition comprising high load carrying capabilities biodiesel metalworking fluids containing a major proportion of biodiesel and with a minor proportion of extreme pressure additives, anti-wear additives, emulsifiers, corrosion inhibitors and antioxidant is formed by:    (A) adding sulfur or zinc salts of dithio organophosphates anti-wear additives to enhance the anti-wear properties of the metalworking fluids;    (B) adding chlorine or phosphorus extreme pressure additives to enhance the load carrying capabilities of the metalworking fluids;    (C) adding nonylphenol or alcohol ethoxylate to enhance the emulsion properties of biodiesel metalworking fluids;    (D) adding sulfonate and amine based corrosion inhibitors to enhance to corrosion inhibition properties of biodiesel metalworking fluids;    (E) adding antioxidant additives to enhance the biodiesel metalworking fluids antioxidant properties; and    (F) adding biocides to enhance the biodiesel metalworking fluids antimicrobial and anti-rancid properties.
