description	Disclosed herein is a method for pretreatment of a metallic substrate for a subsequent metal cold forming process, said method , and contacting at least one surface of the substrate with an aqueous lubricant composition (B). The aqueous lubricant composition (B) has a pH value in the range of from 0.1 to 6.0, and includes water in an amount of at least 40 wt.-%, based on the total weight of the composition (B), at least one film-forming polymer, at least one wax, at least one corrosion inhibitor , and oxalate and/or phosphate anions. Further disclosed herein are a pretreated metallic substrate obtainable by the aforementioned inventive method, a method of cold forming of a metallic substrate including a step of subjecting the inventive pretreated metallic substrate to a cold forming process, an aqueous lubricant composition (B), and a master batch for preparing the aqueous composition (B).
