Abstract
The invention is in the field of hard surface cleaning compositions. There is need for compositions that foam copiously during the washing/cleaning stage. However, during the rinse stage, the foam should rinse-off as quickly as possible in minimum number of rinses-cycles so that the process becomes sustainable. Disclosed is an aqueous cleaning composition, having a pH of 6.5 or lower, comprising (i) 3.0 to 25.0% by weight alkyl ethoxy sulphate; (ii) 1.0 to 5.0% by weight amphoteric surfactant; (iii) 0.1 to 1.0% by weight fatty acids being saturated non-hydroxy C8-12 fatty acid and a saturated non-hydroxy C14-18 fatty acid, where ratio of amount of said C8-12 fatty acid to that of said C14-18 fatty acid is from 1:0.1 to 1:10 parts by weight; and (iv) 0.5 to 5% by weight non-ionic surfactant, wherein (iii) and (iv) together an antifoaming system, and wherein amount of non-alkoxylated anionic surfactant in said composition in less than 1.0% by weight.
