Sodium Isobutyl Xanthate (SIBX) is available in the form of pale-yellow crystals or powdered form in the pure state. It is also available in the form of a solution. In the solid form, SIBX absorbs moisture from the air, and so, it is known as a hygroscopic substance. SIBX emits the odor of carbon disulfide that is somewhat the same as that of decaying cabbage. In some cases, SIBX can emit a very faint unpleasant, or sulfurousodor. SIBX is readily soluble in water and could form insoluble compounds with different metallic ions. Free Alkali:≤0.2% active component:≥90% Solubility:water soluble
