と、防錆性が低下し、また腐敗しやすくなる欠点があっ
た。Therefore, it was necessary to add sulfides such as mineral oil and fats and oils as extreme pressure agents. However, if the amount of sulfide such as mineral oil or oil or fat added is small, the effect will be small, and if the amount added is too large, the rust prevention property will be lowered and the product will be more likely to rot.

極圧効果は小さく満足し得るものではなかった。In addition to the above-mentioned sulfides such as mineral oils and fats and oils, there are also chlorine-based extreme pressure additives such as chlorinated paraffins and chlorinated fatty acid esters, which are extreme pressure additives made of sulfides. Although the degree of deterioration of rust prevention is small compared to
The extreme pressure effect was small and unsatisfactory.

It was common to add amines such as jetanolamine.
しかし、最近、亜硝酸塩とアミン類とが反応して生成す
るＮ−ニトロソアミンの発ガン性が問題となっており、
亜硝酸塩とアミン類との併用は好ましくない。However, recently, the carcinogenicity of N-nitrosamines, which are produced when nitrites react with amines, has become a problem.
Combination use of nitrites and amines is not preferred.
従って、本発明の目的は、極圧性にすぐれ・かつ乳化し
