  • Patent number: 4680315
    Abstract: The invention refers to a powder mixture having a high propylene glycol content and a process for the preparation thereof. The powder mixture consists of 25 to 75 percent by weight of propylene glycol and 75 to 25 percent by weight of magnesium oxide and/or magnesium peroxide and/or magnesium carbonate as a solid carrier(s). The powder mixture can be treated as a solid powder and it does not deliquesce in the air even when stored for a long time. The mixture can be used as solid propylene glycol in dietetic products for calf, piglet and lamb, in pharmaceutical compositions for the treatment of ketosis and in other pharmaceutical compositions for veterinary use.
