The present application concerns an aqueous metalworking composition comprising in a concentrate or after dilution of a concentrate with water in a diluent: 0.002 to 40 % by weight of component (a) which is a lubricity agent comprising at least one water-insoluble compound (a) having at least one hydrophobic aliphatic chain and at least one polar group and having a water solubility at 20 °C of less than 0.1 g/liter; 0.002 to 40 % by weight of component (b)comprising at least one water-soluble corrosion inhibiting compound(b) having a water-solubility at 20 °C of more than 0.1g/liter; 0.002 to 45 % by weight of at least one emulsifying and dispersing agent(c)which contains at least one emulsifying and/or dispersing compound (c) which is water-soluble, water-miscible or water-dispersable and which is selected from the group consisting of non-ionic, anionic and zwitterionic surfactants; 0.002to 30 % by weight of an alkalinity agent (d) containing at least one alkaline water-soluble compound (d) selected from the group consisting of hydroxides and carbonates;and 0.004 to 99 % by weight of a transport component(e)containing predominantly water. Further on, the present application concerns a method of use of such aqueous metalworking composition as a coolant, as a lubricant, etc., and concerns further on a method to prepare an aqueous metalworking composition and a metalworking process. |
