CLEANER FOR CAR AIR-CONDITIONER

摘要

Disclosed is a cleaner for a car air-conditioner, which has cleaning properties, excellent anti-bacterial properties, anti-fungal properties and deodorizing properties, and which has good corrosion-preventing properties and therefore can exhibit its effect stably for a long period without interfering the function of a drive member such as an evaporator.  The cleaner can be produced by injecting a nitrogen gas (as a propellant) into a liquid composition such that the injection pressure of the cleaner is adjusted to 0.6 to 0.9 MPa, wherein the liquid composition comprises (A) 0.1 to 5.0 mass% of a di-(long-chain)-alkyl di-(short-chain)-alkyl ammonium carboxylic acid salt, (B) 0.5 to 5.0 mass% of a plant extract, (C) 0.1 to 5.0 mass% of an organic corrosion-preventive agent having no halogen atom, and (D) 1.0 to 10.0 mass% of a nonionic surfactant having no halogen atom, with the remainder being an alcoholic organic solvent (wherein all of the amounts are expressed relative to the total amount of the liquid composition).
