Donat Mg is a brand name registered by the company Droga Kolinska (located in Ljubljana) which is in turn owned by Atlantic Grupa and also produces Slovenia's best known soft drink, Cockta. Today, Donat Mg is distributed in various European countries. Mineral contents The recommended amount is 500 ml per day. Because of its hyperosmolarity, Donat Mg is a natural osmotic laxative. It is classified as a saline laxative. Its effectiveness as a laxative is due to sulphate salts (magnesium sulphate or Epsom salt and sodium sulphate or Glauber’s salt) and around 1000 mg/l of magnesium. Sulphates draw water from the cells
Magnesium oxychloride at about 23 °C, the completely liquid region has vertices at the following triple equilibrium points (as mass fractions, not molar fractions): The other vertices are pure water, magnesium chloride hexahydrate, and the saturated solution (0.0044 MgO + 0.9956 by mass). The anhydrous forms decompose when heated above 450-500 °C by decomposition of the hydroxide and chloride anions, releasing water and hydrogen chloride and leaving a magnesium oxide residue, by the reactions: Extended exposure of magnesium oxychlorides to water leaches out the soluble , leaving hydrated brucite . On exposure to the atmosphere, the oxychlorides will slowly react with carbon
