2. Description of the Related Art In general, plastics including fiber reinforced plastics, tiles, stainless steel, ceramics, glass, and the like are used for various facilities and tools such as bathrooms in houses. One of the main stains adhering to the hard surface of such a member is, for example, a fatty acid metal salt (soap residue) generated by combining a fatty acid contained in soap or body shampoo with calcium in tap water. Is mentioned. Conventionally, as a cleaning agent for removing such dirt,
An acidic detergent containing a hydroxycarboxylic acid as an acidic substance, a surfactant and a water-soluble solvent is known (Japanese Patent Application Laid-Open No. 52-77111). However, although such an acidic cleaning agent has a cleaning effect, it may damage bathroom floors, tile joints such as walls, and living materials such as aluminum sashes. Also, if mixed with a chlorine bleach by mistake, chlorine gas may be generated.

[0003] In order to solve this problem, in the neutral region, many detergents having excellent detergency against stains such as fatty acid metal salts have been developed. For example, JP-A-53-357
No. 10 discloses a bathroom cleaner combining an anionic surfactant, a nonionic surfactant, a glycol ether-based solvent, citric acid and the like, and JP-A 61-283696 discloses a cationic surfactant and a non-ionic surfactant. Neutral detergent combining ionic surfactant, JP-A-61-28369
No. 7 discloses a detergent comprising a combination of a cationic surfactant, a nonionic surfactant and a water-soluble solvent.
JP-A 1-283700 discloses a detergent combining a cationic surfactant, a nonionic surfactant and maleic acid, and JP-A 1-222197 discloses a cationic surfactant and a nonionic surfactant. Bathroom cleaners and the like in which an aminocarboxylic acid and a solvent are combined are disclosed.

[0004] However, none of the cleaning agents disclosed in these publications simultaneously satisfy the detergency, foaming power and rinsing properties.

[0005]
