Abstract (en)
[origin: WO9409108A1] Ideal household cleaning compositions should form a relatively stable foam on application to a surface and rapidly de-foam when rinsed from the surface. The present invention subsists in an aqueous cleaning composition comprising: (a) a surfactant system comprising an anionic surfactant other than an alkali metal salt of a fatty acid, (b) C10-C18 monocarboxylic fatty acid, (c) a semi-polar solvent, (d) a polycarboxylic acid, and (e) a base, said composition having a pH of less than 6. It is believed that the C10-18 fatty acids have a foam boosting effect which improves 'cling' of the foam to sloping or vertical surfaces. When the compositions are diluted during rinsing the fatty acid and the solvent form an antifoam system which defoams the composition.
