The commercial products are formulated with 30-35% of water, or ethanol, or 1-butanol or Isopropanol.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvents also consult the ICSCs of these materials.
The formulation with more than 12.6% nitrogen is used exclusively for the explosives; EU classification: Index number 603-037-00-6, symbol E, R:1-3, S:(2-)35.
