Abstract
A thickened hard surface abrasive cleanser is provided which may have high levels of silicates for superior cleaning, exhibits substantially no syneresis, and has a use-favorable rheology. The cleanser comprises, generally: PA1 (a) an alkali-metal silicate/borate anion thickener PA1 (b) an electrolyte/buffer PA1 (c) an anionic surfactant; and PA1 (d) a particulate abrasive. The composition of the invention is attained only on following a defined formulation protocol. Accordingly, a method is provided which yields the inventive composition. The composition may be formulated to a viscosity of between about 10,000 and 250,000 cP, and a yield value of between about 1 and 80 Pa.
