Alkali detergents include nonionic surfactants typified by polyoxyethylene alkylphenyl ethers, anionic surfactants typified by sodium alkylbenzenesulfonate, sodium carbonate, sodium silicate, and borosurfactants. Alkali salts such as sodium phosphate, sodium phosphate, sodium hydroxide, potassium hydroxide, sodium tripolyphosphate, EDTA, NTA,

For example, Tsuji recommendation "Precision cleaning technology" engineering book p117-
120, "Precision Cleaning Technology Manual" edited by Tsuji recommended, New Technology Development Center, p50-56, various articles have been proposed according to the article to be cleaned, metal, and dirt. However, since the degreasing power and penetrating power are inferior to chlorine-based solvents such as 1,1,1-trichloroethane, practical application fields are cleaning of articles having a simple structure and residual oil content after cleaning. Most of the fields are not so important.

On the other hand, chlorine-based solvents such as 1,1,1-trichloroethane have excellent degreasing and penetrating powers and can be applied to all kinds of degreasing such as cutting oil, drawing oil and press oil.
It is used in the field of cleaning articles with complex structures and precision parts that require high cleanliness. However, in recent years, environmental problems such as groundwater pollution due to chlorine-based solvents, air pollution, and ozone layer depletion have become prominent, and in the industrial world, conventional alkaline cleaners have been applied as cleaners to replace them. I am doing it.

However, conventional alkaline cleaners are inferior in degreasing power and penetrating power to chlorine-based solvents, and especially cutting oil, drawing oil and press oil adhere to narrow gaps and details. It cannot be applied when there is a problem, or when a very small amount of residual oil on the surface of a component is a problem. It is considered that a large amount of nonionic surfactant is used in order to improve the degreasing power and penetrating power, but it is difficult to make a stable concentrated liquid as a product.

Further, it is possible to increase the pH by increasing the amount of alkali salt in order to enhance the degreasing power, but this also makes it difficult to form a stable liquid product as a product.
It is not preferable from the viewpoint of influence on non-ferrous metals and safety for workers. As a stable liquid method, for example, there is a method of using sodium aromatic carboxylate in combination as shown in Japanese Examined Patent Publication No. 63-13480, and paratertiary used as a representative of sodium aromatic carboxylate. Sodium butylbenzoate has a problem that it is highly toxic to the kidney and liver.

Further, in the case of finishing cleaning after performing precision processing, cleaning before performing product inspection such as airtightness test and dimension inspection, cleaning before applying rust preventive oil, cleaning agent Since the residue has an adverse effect, it is essential to remove the cleaning agent adhering to the parts by rinsing with water. However, when rinsing with water, it is necessary to treat a large amount of rinse wastewater, so conventionally only chlorine-based solvents are used, and there is no wastewater treatment facility, or where there is no wastewater treatment facility. In the place where the treatment amount cannot be increased in terms of capacity, a conventional alkaline detergent cannot be easily applied, and therefore, an aqueous detergent that can be used without rinsing with water is desired.
