International Chemical Safety Cards DIISONONYL PHTHALATE ICSC: 0831 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: OILY VISCOUS LIQUID PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Tumours have been detected in experimental animals but may not be relevant to humans.
