Rock salt is another name for the mineral halite which is commonly known as sodium chloride and has a chemical formula NaCl. The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on the amount and type of impurities or insoluble minerals. Rock salt is often used both residentially and municipally for managing ice. Because brine (a solution of water and salt) has a lower freezing point than pure water, putting salt on on ice that is near 0 °C (32 °F) will cause it to melt.
Ice melt blends provide an enhanced melting capacity and will work to lower temperatures than traditional 100% sodium chloride deicers. With the addition of Magnesium Chloride or Polyol to a sodium chloride base, the ability is added to not only lower the products melting temperature but also adding residual melting capabilities.
