Abstract (en)
The present invention relates to liquid acidic thickened compositions having a viscosity of at least 10 m Pa s, when measured with a Carri-med rheometer at 5 N/m<2> at 20 DEG C, and a pH below 4, said composition comprising a thickening system comprising a zwitterionic surfactant and an anionic surfactant at a weight ratio of said zwitterionic surfactant to said anionic surfactant of at least 2:1, and from 0.1% to 70% by weight of the total composition of an acid. Said compositions deliver excellent limescale removal performance as well as outstanding greasy soap scum cleaning on hard-surfaces. The compositions are suitable for the cleaning of non-horizontal and horizontal surfaces.
