The present invention relates to machine cleaners effective in removing oily contaminants. Specifically, the present invention relates to a machine cleaner having an excellent cleaning action for removing oily contaminants such as machine oil. Conventionally, petroleum-based hydrocarbon oils such as benzine, gasoline, kerosene, and mineral spirits are commonly used as cleaning fluids to remove oil-based contaminants, including oil and various dusts, from machines and their parts. However, when removing stubborn contaminants,
The use of petroleum-based hydrocarbon oils such as gasoline, kerosene, and mineral spirits alone as cleaning fluids is often insufficient. As a method to improve these conditions, there is a method of removing contaminants by adding a physical action of scraping or scraping the contaminants off the surface of the object to the chemical action of the dissolving power of petroleum-based hydrocarbon oil. It takes a lot of effort and is not always sufficient. As a result of repeated research on machine cleaners with excellent cleaning action for removing oil-based contaminants adhering to machines and their parts, the present inventors found that a specific surfactant was added to hydrocarbon oil with dissolving power. The present invention was completed based on the discovery that a cleaning composition to which hydrocarbon oil is added has a cleaning effect superior to that obtained when hydrocarbon oil is used alone. The present invention relates to a machine cleaning agent characterized in that the adduct of secondary alcohol alkylene oxide is contained in an amount of 0.1 part by weight or more per 100 parts by weight of hydrocarbon oil. The secondary alcohol alkylene oxide adduct to be added to the hydrocarbon oil of the present invention has excellent compatibility with the hydrocarbon oil, and when added to the hydrocarbon oil, it becomes a homogeneous and transparent liquid. Alcohol alkylene oxide adducts have low viscosity and therefore can be easily mixed with hydrocarbon oils. The secondary alcohol alkylene oxide adducts used in the present invention include the following. (a) an adduct obtained by adding an average of 2 to 10 moles of alkylene oxide to a secondary alcohol having 8 to 16 carbon atoms;
Particularly preferred is an adduct obtained by adding an average of 2 to 7 moles of alkylene oxide to a secondary alcohol having 10 to 14 carbon atoms. (b) Adducts in which 2 to 10 moles of ethylene oxide and propylene oxide are added blockwise and/or randomly to a secondary alcohol having 8 to 16 carbon atoms, particularly ethylene oxide to a secondary alcohol having 10 to 14 carbon atoms. and propylene oxide in a block and/or random manner with an average of 2
Adducts containing ~10 moles are preferred. (C) An adduct obtained by adding an average of 2 to 10 moles of alkylene oxide to a secondary alcohol having 8 to 16 carbon atoms, and a secondary alcohol having 8 to 16 carbon atoms with ethylene oxide and propylene oxide in blocks and/or randomly. A mixture of 2 to 10 moles of adduct on average. The hydrocarbon oil used in the present invention ranges from 30 to
Petroleum-based hydrocarbon oils with a boiling point range of 350°C are effectively used, including industrial volatile oils, industrial solvents, heavy solvents, odorless solvents, and highly aromatic solvents, especially gasoline, naphtha, mineral spirits, and turpentine. Oil, kerosene are preferred. Specific examples of these include Nippon Oil White Gasoline, A Solvent, Cleansol, Dry Solvent, K Solvent, Mineral Spirit A, New Sol DX, No. 3, No. 4, No. 5, No. 6 Solvent, Hyalom No. 2S0 Solvent, Mobil Pegasol 1725N, Pegasol AN45, Pegasol 3040, Pegasol AS100, Pegasol R100,

The compounding ratio of the secondary alcohol alkylene oxide adduct used in the cleaning composition of the present invention is 0.1 part by weight or more, 0.1 part by weight or more based on 100 parts by weight of hydrocarbon oil.
A range of from 1 to 10 parts by weight is preferred, particularly from 1 to 10 parts by weight. The cleaning composition of the present invention has a synergistic effect between the hydrocarbon oil that has the ability to dissolve oil-soluble contaminants and the secondary alcohol alkylene oxide adduct that has excellent penetrating power, so that it can be used as a cleaning agent alone. It is possible to improve the cleaning performance even better than when using the same method. The machine cleaner of the present invention is extremely effective in dissolving and removing oil-based contaminants such as fats and oils and machine oil. The cleaning composition of the present invention is prepared by dissolving at least one secondary alcohol alkylene oxide adduct in a hydrocarbon oil, and optionally includes an antioxidant, an acidic agent, and an alkali dissolved in the hydrocarbon oil. Builders, fungicides, perfumed paints, etc. can also be added. Next, the present invention will be explained in more detail with reference to Examples. The test methods used in the examples are as follows. (1) Appearance test After preparing a cleaning agent and leaving it for 2 hours, the appearance was evaluated as follows. ○: Completely dissolved and becomes transparent. Δ: Dissolved but slightly cloudy. ×: Separation (2) Machine oil cleaning power test Machine oil [Drawing oil (press work oil, high viscosity product)]
was applied onto a slide glass, immersed in the mechanical cleaning agents shown in Tables 1 to 3, and the state of dissolution after 24 hours was examined and evaluated in the following manner. ○: Well dissolved △: Slightly dissolved ×: Not very soluble Examples 1 to 8 An average of 2 to 10 moles of various secondary alcohol alkylene oxides were blended into the white gasoline (manufactured by Nippon Oil Co., Ltd.) shown in Table 1. Various cleaning agents were prepared. Table 1 shows the appearance of the cleaning agent and its cleaning power for machine oil.
It was as shown in. Comparative Examples 1 to 5 Various cleaning agents shown in Table 1 were prepared. The appearance and machine oil detergency of the detergent were as shown in Table 1.
