SODIUM CITRATE DIHYDRATE ICSC: 1219
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE SOLID IN VARIOUS FORMS.

CHEMICAL DANGERS:
The solution in water is a weak base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK: IIb (not established but data is available) (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the respiratory tract.

PHYSICAL PROPERTIES
Melting point (decomposes): 150C
Solubility in water: 77 g/100 ml
ENVIRONMENTAL DATA

NOTES
The apparent melting point caused by loss of crystal water is given.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
