PROBLEM TO BE SOLVED: To provide a water-soluble plunger lubricant for die-casting, which suppresses combustion and exhibits excellent lubricating properties without causing reduction in productivity or deterioration of working environment.SOLUTION: The water-soluble plunger lubricant for die-casting comprises: a component (a) which is one or more compounds selected from mineral oils, synthetic hydrocarbons, fats, and fatty acid esters; a component (b) which is one or more compounds selected from alkali metal salts of higher fatty acids or alkali metal salts of aliphatic hydroxy acids; a component (c) which is one or more compounds selected from alkali metal salts of synthetic sulfonic acids or alkali metal salts of petroleum sulfonic acids; microparticulate silica; and water. The water-soluble plunger lubricant for die-casting suppresses combustion and exhibits excellent lubricating properties without causing a decrease in productivity or deterioration of working environment.
