Abstract
The present invention relates to a solid, particulate, non-explosive composition comprising ammonium nitrate-based particles, in particular a fertilizer composition, of which, on the one hand, the potential misuse as a precursor for an explosive composition is limited without, on the other hand, hampering its legitimate use by farmers for food production. The solid, particulate, non-explosive composition further comprises a gelling agent which is able to form a substantially water-insoluble and non-filterable hydrogel after the solid fertilizer composition is contacted with water. The gelling agent is selected from the group of gum-based gelling agents, in particular xanthan gum-based agents and guar gum-based agents, most preferably is a xanthan gum-based agent.
