(57) [Problem] To provide a non-polluting lubricant which is excellent in lubricating properties and replaces conventional lubricating oil. SOLUTION: In addition to containing 1 to 15% by mass of sucrose, 0.001 to 1% by mass of an alkali metal salt of a fatty acid, further containing a preservative and a rust inhibitor, and the remainder being water (pure water) A lubricant is formed from the aqueous solution as described above. More specifically, Sodium laurate is used as an alkali metal salt of a fatty acid. As the preservative, potassium sorbate is employed, and the amount thereof is 0.1%. Benzotriazole and its alkali metal salt are employed as the rust preventive, and the amount of addition is 0.1 to 3% by mass. Further, the aqueous solution having the above-mentioned composition is subjected to a nanomizer treatment to be used as a lubricant. |
