Thickened acid composition

A thickened, shear thinning acidic compositions which comprises approximately by weight:

• (a) 0 to 5 percent of an anionic surfactant;
• (b) 1 to 5 percent of a nonionic surfactant;
• (c) 0 to 1.0 percent of a preservative;
• (d) 0.3 to 2.5 percent of a polyurethane/polyol polymeric thickener having a molecular weight of about 1,000 to about 1,000,000;
• (e) 0 to 10 percent of a disinfectant;
• (f) 0 to 1.0 percent of phosphoric acid;
• (g) 0 to 0.5 percent of an amino alkylene phosphonic acid;
• (h) 1 to 10 percent of a mono or dicarboxylic acid;
• (i) 0.1 to 2 percent of a perfume, essential oil or water insoluble hydrocarbon;
• (j) 0 to 10 % of a mineral acid;
• and
• (k) the balance being water, wherein the composition has a pH of about 1 to about 4 and a Brookfield viscosity of about 200 to 1,000 cps at R.T. using a #2 spindle at 50 rpms.
