A composition for cleaning membranes used in food processing comprising an amine oxide and an alkyl sulfate, the composition maintaining good cleaning performance whilst leaving a low residue of surfactant on the membrane that is cleaned using the composition. A method of use of the composition is also presented.

Cleaning composition

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 C-alkyl dimethylamine oxide or C-alkyl diethylamine oxide or C-alkyl methylethylamine oxide; a linear and/or branched C-alkyl dimethylamine oxide or C-alkyl diethylamine oxide or C-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&#x2014;(AO)&#x2014;A'&#x2014;COOM (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&#x2032; 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;&#x2014;a source of alkalinity; and&#x2014;water.
