International Chemical Safety Cards GLUTARALDEHYDE (50% SOLUTION) ICSC: 0352 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: CLEAR COLOURLESS LIQUID , WITH PUNGENT ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.05 ppm; (ceiling values) (ACGIH 1999). MAK: 0.1 ppm; 0.4 mg/m3; (1999) ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is severely irritating to the respiratory tract and is corrosive to the eyes and the skin. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma (see Notes). PHYSICAL PROPERTIES Boiling point: 101°C Melting point: -6°C Relative density (water = 1): 1.1 Solubility in water: miscible Vapour pressure, kPa at 20°C: 2.3 Relative vapour density (air = 1): 1.05 ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. N O T E S The occupational exposure limit value should not be exceeded during any part of the working exposure. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. Also consult ICSC #0158 Glutaraldehyde.
