Carnallite material having reduced moisture absorption, which comprises carnallite particles typically having a diameter of from 0.5 to 10 mm, coated with a soft wax that is solid at room temperature. The amount of the soft wax may be at least 0.05 %, or from 0.15 to 3 %, by weight of the weight of the uncoated carnallite particles. The soft wax may be prevalently constituted by paraffinic hydrocarbon compounds, such as about 90 % paraffins and isoparaffins having from 20 to 40 carbon atoms. Up to 40 wt% of paraffinic oil may be added to the soft waxes. |
