Abstract

The invention relates to an aqueous foaming cleaning composition for removing soil at low temperatures from a surface to be cleaned, characterized in, that the aqueous foaming cleaning composition comprises: a linear and/or branched C12-alkyl dimethylamine oxide or C12-alkyl diethylamine oxide or C12-alkyl methylethylamine oxide; a linear and/or branched C14-alkyl dimethylamine oxide or C14-alkyl diethylamine oxide or C14-alkyl methylethylamine oxide; at least one anion tenside of: a dodecyl (oxyethylen)w sulfat, wherein w represents an average addition mole number ranging from about 1 to about 10, and/or at least one polyoxyalkylene alkyl ether carboxylic acid or salt thereof represented by formula (I): RO—(AO)n−1—A′—COOmM (I) wherein, R represents a linear and/or branched alkyl group having about 8 to about 18 carbon atoms; AO represents an alkylene oxy group having about 2 to about 4 carbon atoms; n represents an average addition mole number ranging from about 1 to about 20; A′ represents an alkylene group having about 1 to about 3 carbon atoms; M represents H or a cation; and m represents the number equal to a valence number of M;—a source of alkalinity; and—water.
