International Chemical Safety Cards PENTABROMODIPHENYL ETHER (Technical product) ICSC: 1612 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: AMBER VISCOUS LIQUID PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic fumes including hydrogen bromide or bromine. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the liver . PHYSICAL PROPERTIES Boiling point (decomposes): 200-300°C Melting point: -7 - -3°C Relative density (water = 1): 2.25 - 2.28 Solubility in water, g/100 ml at 20°C: 0.0013 (very poor) Vapour pressure, Pa at 21°C: negligible Octanol/water partition coefficient as log Pow: 6.57 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in seafood. N O T E S The substance accumulates in fat tissues and can be excreted in breast milk. Technical pentabromodiphenyl ether is a mixture of tetra-, penta-, and hexabromodiphenyl ethers.
