Chemical formula C4H6O5 C.A.S number 004-525-33-1 Formula weight 134.09 Appearance Colourless liquid Assay Not less than 99.8% Density 1.25g/cm3(20C/68F) Application Using for the different beverages: flavored water energy drinks tea drinks juice till 100% Mechanism of efficiency of DMDC DMDC can permeate through the cell membrane, and block the metabolism through reacting with the enzymes of microorganism, then achieve the purpose of sterilization. Even in very low additive amount, DMDC can effectively kill typical spoilage bacteria in beverage, and not affect the taste, flavor and color of the beverage. Furthermore, it could be rapidly and completely hydrolyzed to carbon dioxide and methanol, which are the natural ingredients of juice. Package Gauga: 4KG/20KG Storage conditions In optimal storage conditions (storage temperature: 20C-30C), the storage period is one year

HiraChem is your specialist supplier of Silver Mercury. Mercury (also known as quicksilver) is the only metal which is liquid at room temperature - it is well known for it's use in thermometers, but it is also widely used in scientific research, for dental restoration and in lighting. Mercury forms alloys with different metals easily - these alloys (called amalgams) can be used for creating dental fillings and are in use to create long-life batteries. IT'S MAIN APPLICATIONS ARE: AS CATALYST FOR THE PRODUCTION OF PVC (POLYVINYL CHLORIDE) IN ENERGY EFFICIENT CFL (COMPACT FLUORESCENT LIGHT) BULBS IN CATHODE CELLS IN INDUSTRIAL CHEMICALS IN PAINTS
