International Chemical Safety Cards DICYCLOHEXYL PHTHALATE ICSC: 0651 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE CRYSTALLINE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts with acids , bases . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the l liver . PHYSICAL PROPERTIES Boiling point at 0.5 kPa: 222-228°C Melting point: 66°C Relative density (water = 1): 1.4 Solubility in water: none Vapour pressure, Pa at 150°C: 13.3 Flash point: 207°C Octanol/water partition coefficient as log Pow: 3-4 ENVIRONMENTAL DATA It is strongly advised not to let the chemical enter into the environment because it persists in the environment. N O T E S Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
