Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning composition for vehicles such as bicycles.

[0002]

2. Description of the Related Art Dirt mainly composed of atmospheric dust adheres to the surface of automobiles and railway vehicles during running or parking. These dusts contain a large amount of iron, and the iron that has adhered to the surface of the vehicle becomes moist and sea salt particles on the coating film and the metal surface with the passage of time, and also SO _x and NO _{x in the} atmosphere. Corrosion reaction progresses due to a synergistic effect with corrosive gas such as iron or the like, and metallic iron turns into a ferrate or hydroxide and adheres or adheres to a coating film or a metal surface. In addition, even if the form of iron is not iron, even if it is attached in the form of iron hydroxide or iron oxide, it is accompanied by a chemical reaction based on the above-mentioned reactions, so it is not merely a state of accumulation but sticking. And it is very difficult to remove it with a normal cleaning agent. In addition, the brake pad is scraped by the friction between the brake pad and the brake rotor that occurs when the brake is depressed, and powder (brake dust) of the scraped brake pad adheres to the wheel of the automobile. This powder also contains a large amount of iron powder, and after adhesion, the same phenomenon as described above also occurs.

[0003] As a method for removing such iron powder, a cleaner of the type in which an abrasive is blended with a conventional plastic viscosity (trade name: TRANDEND, manufacturer: JOYBON)
Cleaners that use D) to mechanically polish while applying water to the surface of the coating film are exclusively used, but other methods include compounds selected from thiocarboxylic acids, their alkali metal salts, ammonium salts and amine salts. A method of removing iron powder by using one or two or more cleaning agents has been reported in Japanese Patent Publication No. 5-25279.

[0004]

The effect of iron powder removal by a compound selected from thiocarboxylic acids, their alkali metal salts, ammonium salts and amine salts is certainly effective as reported. However, these compounds are not always safe for metals. In the above report, as a safety test, it is reported on painted surfaces and aluminum, but various metal and plating are applied to actual replacement parts such as automobile parts and air valve caps of tires, Ni-Cr, Zn
-SU used for Ni-based plated steel sheet and muffler
In step S410, the compound causes a change such as discoloration.
Particularly in summer, the reaction is accelerated by the influence of temperature, and such a situation is likely to occur. In addition, thiocarboxylic acids and their alkali metal salts, ammonium salts and amine salts have a peculiar off-flavor and give an unpleasant sensation during work.

[0005]

The detergent composition of the present invention comprises a nonionic surfactant having one or more compounds selected from thiocarboxylic acids, their alkali metal salts, ammonium salts and amine salts. It is characterized by comprising an agent, an anionic surfactant and a fragrance. The nonionic surfactant is 1 to 20% by weight, the anionic surfactant is 0.1 to 0.5% by weight, and the fragrance is 0.01 to 2.0% by weight.

According to the detergent composition of the present invention, it is possible to minimize the change in the discoloration and the like of the above-mentioned metal and plated steel sheet due to the detergent while maintaining the detergency, and furthermore, thiocarboxylic acids and their alkali metals Unique off-flavors due to salts, ammonium salts and amine salts can be masked.

[0007]
