、加工油剤の加工性や防錆性等が低下するだけでなく、

ている。[Prior Art] Traditionally, water-diluted processing oils have been used for processing metals such as aluminum for reasons such as ease of handling and cleaning. Components, processed metal powder, etc. serve as a nutrient source for the growth of microorganisms, resulting in the decomposition and deterioration of the oil. For this reason, not only the processability and rust prevention properties of the processing oil decrease, but also
Odors are generated and nozzles and piping are blocked, resulting in poor work hygiene and work efficiency, which necessitates replacing the oil.
【０００３】このような問題に対処するために、殺菌剤

、比較的短期間の使用によって、殺菌剤等が消費される
ので、これらの成分を適宜補充しなければならないだけ

て、十分な殺菌効果や防黴効果が得られなくなる。[0003] In order to deal with such problems, measures have been taken to incorporate fungicides, antifungal agents, etc. into processed oils, but since the fungicides are consumed after a relatively short period of use. Not only do these components have to be replenished appropriately, but also sufficient bactericidal and antifungal effects cannot be obtained due to the development of resistant bacteria due to long-term use.

点がある。[0004]Although antibacterial water-dilutable metalworking fluids containing specific alkyl diamines are known (Japanese Patent Application Laid-open Nos. 1-201400, 2-228394 and 2-228395), (see publication), it has the disadvantage that it cannot sufficiently suppress the growth of bacteria, mold, and yeast.

It will be done. When a fatty acid or its ester is condensed with diethanolamine in a 1:1 molar ratio, a fatty acid alkanolamide with n≈0 is obtained, and when it is condensed with a 1:2 molar ratio, a fatty acid alkanolamide with n≒1 is obtained. In this way, n can be adjusted by the molar ratio of fatty acid and diethanolamine,
Particularly preferred for the present invention are fatty acid alkanolamides with n≈0-1. Fatty acid has 10 carbon atoms

Since the deterioration is small, not only stable processability and excellent rust prevention properties can be obtained over a long period of time, but also, since the processing oil itself has antibacterial properties, there is no need for additional disinfectants. Furthermore, since the processing oil has low toxicity and irritation to the human body, there is no problem in terms of work hygiene.
