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 dioxide from the air to form magnesium chlorocarbonates. Anhydrous and partially hydrated forms also absorb water, turning into phase 5 and then phase 3 on the way to the chlorocarbonate. The exceptions are the dihydrate and hexahydrate of phase 9, that remain unchanged for many months. The crystal structure of phase 3 is triclinic with space group formula_1 and "z" = 2. The solid consists polymeric aquohydroxo cations, in the form of double chains of magnesium atoms surrounded and bridged by the oxygen atoms in hydroxy groups and complexed water molecules. These linear cations are interleaved and neutralized by chloride
