Provided are a lubricant coating agent which can reduce industrial waste (environmental conservation), and impart excellent lubricity in a water-containing state even in the case of carrying out no forced drying after a lubrication treatment step (drying at room temperature, leaving at room temperature), or even to metallic products in shapes that are difficult to dry completely, e.g., the inner surfaces of steel pipes, as well as techniques related thereto. n A water-containing lubricant coating agent, on use in metal plastic working carried out in a water-containing state with a water content of 3 to 50 mass%, characterized in that at least one lipophilic lubricating component (A) and/or at least one solid lubricant (B) with cleavability are dispersed in water, and furthermore, at least one water-soluble lubricating component (C) selected from the group consisting of fatty acid components having 12 to 20 carbon atoms is dissolved in a water-phase side at a mass ratio of (C)/[(A) + (B)] = 0.05 to 0.5. |
