Abstract:
A cleansing solution for cleansing a surface where microorganisms belonging to the genus Legionella likely exist, wherein the solution is canned with propellant gas and capable of being sprayed on the surface, the cleansing solution comprising:an antimicrobial agent for selectively eradicating microorganisms belonging to the genus Legionella, wherein the antimicrobial agent comprises at least one amine oxide represented by the formula (1) and/or at least one amine oxide represented by the formula (2): ##STR7##wherein R.sub.1 represents C.sub.n H.sub.2n+1 (OC.sub.2 H.sub.4).sub.m, n varies from 12 to 18, m varies from 0 to 10, R.sub.2 represents a hydrogen or alkyl group having from 1 to 4 carbon atom(s), and the solid arrow represents a coordinate bond between a nitrogen and oxygen; ##STR8##wherein R.sub.1 represents C.sub.n H.sub.2n+1 (OC.sub.2 H.sub.4).sub.m, n varies from 12 to 18, m varies from 0 to 10, R.sub.3 represents (C.sub.p H.sub.2p)OH with p varying from 1 to 4, and the solid arrow represents a coordinate bond between a nitrogen and oxygen, said cleansing solution including a minimum of 0.7% of said amine oxide;a pH regulator to regulate the pH value of said solution, said pH regulator including at least 1.5% of metasilicate;at least 0.5% of sodium decyl sulfate and at least 2% of polyoxyethylene oleoyl ether;a compound having a boiling point between 10.degree. C. and 40.degree. C. to generate foam after spraying the cleansing solution on the surface;an additional surfactant including at least one surfactant of an anionic-type;a thickener to provide the cleansing solution with a certain viscosity, wherein the thickener is a material selected from the group consisting of sodium alginate, propylene glycol alginate esters, carboxymethyl cellulose (CMC) esters, sodium carboxy methyl cellulose, starch sodium glycolate, starch sodium phosphate esters, methyl cellulose, sodium polyacrylate, cellulose esters, alginic acid, casein, and poly-N-vinyl acetamide.
