PROBLEM TO BE SOLVED: To provide a novel dispersed hydrated sodium borate composition having reduced turbidity, good mixing properties, and improved water durability. A hydrated sodium borate composition comprising a hydrated sodium borate, a dispersant, and an oil of lubricating viscosity, wherein the hydrated sodium borate has a hydroxyl group: boron (OH: B). Of about 0.80: 1 to 1.60: 1 and a ratio of sodium to boron of about 1: 2.75 to 1: 3.25. Sodium borate composition. |
