  • Composition and probe for detection of water
    Patent number: 6376250
    Abstract: A visual indicating paste composition for detecting of aqueous solutions in hydrocarbons by changes in color. The paste is utilized by placing on a probe and inserting the probe in a storage device for fuel. Said paste comprising: a) a liquid carrier selected from high molecular weight polyols; b) a caustic powder selected from alkaline earth oxides; c) a gelling agent; d) a surfactant consisting of ethoxylated nonylphenol with 9 moles of ethylene oxide; e) a filler material. f) a water scavenger consisting of aluminum isopropoxide; g) an indicator dye; and h) a neutral dye; wherein the paste of the present invention will change color upon contact with an aqueous solution in the pH range of about between 7 and 11.
