NITROCELLULOSE (less than 12.6% nitrogen ) ICSC: 1560
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE SOLID IN VARIOUS FORMS

CHEMICAL DANGERS:
Spontaneously flammable when dry. The substance decomposes rapidly on burning causing fire and explosion hazard, producing nitrogen oxides. Reacts with oxidants, bases and acids.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
EFFECTS OF SHORT-TERM EXPOSURE:
See Notes.

PHYSICAL PROPERTIES
Relative density (water = 1): 1.66
Solubility in water: none
ENVIRONMENTAL DATA

NOTES
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.
