Persistence and Degradability PBT and vPvB Assessment
Inherently biodegradable. Does not bioaccumulate.
Bioaccumulative Potential Other Adverse Effects
Does not bioaccumulate.
Non-reactive under recommended storage conditions. May react with strong oxidizing or reducing agents, aluminum (at
high temperatures), and diazomethane.
Stable under recommended storage conditions. Avoid excess sources of ignition, heat, and incompatible materials.
Dust suspended in air is readily ignited.
Thermal decomposition may produce CO, CO
2
, oxides of sulfur, oxides of calcium, oxides of
nitrogen, and hydrocyanic acid.
May cause gastrointestinal tract irritation, disorder/damage. Intestinal obstruction may occur if the material hardens.
Large amounts released to water systems may
harm aquatic plant and animal life.
