Chemistry
The substance is a mixture of disodium glycerol 1- and 2-phosphates, which have different amounts of water of crystallization; the total amount is 5+1⁄2 H2O per glycerol phosphate molecule. It is a white to off-white powder which may or may not be crystalline, has no discernible odor and tastes salty. It melts at 98 to 100 °C (208 to 212 °F) and decomposes at 130 °C (266 °F). Aqueous solutions have a pH of about 9.5.[7]
