Abstract (en)

[origin: EP1835012A1] A lubricating composition for cold working which has good lubricating and anti-seizure properties and which is less flammable without addition of a chlorine compound and a method for cold working using the same are provided. The lubricating composition for cold working comprises at least one carbonate selected from alkali metal carbonates and alkaline earth metal carbonates and at least one hydroxide selected from alkali metal hydroxides and alkaline earth metal hydroxides in a lubricating base oil and which is free of chlorine compounds, wherein the content of the carbonate in the composition is at least 10% by mass and less than 100% by mass and wherein the content of the hydroxide is greater than 0 parts by mass and at most 5 parts by mass per 100 parts by mass of the carbonate.
