Cleaner for car air-conditioner

Abstract

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).

Description

technical field [0001] The present invention relates to a detergent capable of being efficiently adsorbed on base materials of automobile air conditioners such as aluminum, Metal materials such as aluminum alloys, magnesium alloys, and iron alloys, and resin materials such as hydrophilic resins such as acrylamide coated thereon.
