Liquid drain opening composition and method
Abstract
Abstract AN AQUEOUS SOLUTION OF BETWEEN ABOUT 1% AND 9% BY WEIGHT SODIUM OR POTASSIUM HYPOCHLORITE AND BETWEEN ABOUT 2% AND 9% BY WEIGHT SODIUM OR POTASSIUM HYDROXIDE PROVIDES A VERY EFFECTIVE DRAIN OPENER WHICH IS NOT AS HAZARDOUS TO USE AS THE CONVENTIONAL HIGHLY CONCENTRATED CAUSTIC DRAIN OPENERS. BETWEEN ABOUT 1% AND 7% BY WEIGHT SODIUM OR POTASSIUM CHLORIDE IS PRESENT IN THE SOLUTION, AND THE POTASSIUM ION CONCENTRATION IN THE DRAIN OPENER SOLUTION IS IN EXCESS OF THE SODIUM ION CONCENTRATION. SODIUM OR POTASSIUM SILICATE MAY BE INCLUDED IN THE DRAIN OPENER SOLUTION TO INHIBIT THE CORROSIVE ACTION OF THE SOLUTION UPON METAL PLUMBING FIXTURES, AND A SMALL AMOUNT OF A WETTING AGENT, OR IN OTHER WORDS SURFACE ACTIVE AGENTS, INCREASES THE RATE AT WHICH THE DRAIN OPENER SOLUTION PENETRATES FATTY MATERIAL.
