The invention pertains to liquid scouring compositions comprising by weight of the total composition, from 1 to 65% of a particulate abrasive material, and from 35 to 99% of an aqueous liquid suspending medium, which comprises, by weight of the medium: (a) from 3 to 15% of a synthetic anionic detergent-active material; (b) from 1 to 12% of a zwitterionic and/or alkoxylated nonionic detergent-active material; (c) a foam-regulating system comprising: 1. from 0.5 to 7% of tripolyphosphate electrolyte; and 2. from 0.05 to 8% of a Ca2+-dependent foam-depressing agent; the weight ratio between component (1) and component (2) being within the range of from 1:1 to 8:1; and (d) optionally, up to 20% by weight of further electrolytes. Compositions according to the invention show good physical and chemical stability and improved foam/rinse properties. |
