Chemical Safety
0458 2,4-XYLENOL
IMPORTANT DATA
Physical State; Appearance Routes of exposure
YELLOW TO BROWN LIQUID OR COLOURLESS CRYSTALS. The substance can be absorbed into the body by inhalation, by
ingestion and through the skin.
Chemical dangers
Inhalation risk
The substance decomposes on burning producing toxic gases
and irritating fumes. Reacts with acid anhydrides, acid chlorides, No indication can be given about the rate in which a harmful
bases, oxidants. concentration in the air is reached on evaporation of this
substance at 20/C.
Occupational exposure limits
Effects of short-term exposure
TLV not established.
MAK not established. The substance is corrosive to the skin the respiratory tract and
the eyes. Corrosive on ingestion. Inhalation of an aerosol of this
substance may cause lung oedema (see Notes).
Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Boiling point: 211.5/C Flash point: >112/C c.c.
Melting point: 25.4-26/C Auto-ignition temperature: 599/C
Density: 0.97 g/cm3 Explosive limits, vol% in air: 1.1-6.4
Solubility in water, g/100 ml at 25/C: 0.79 Octanol/water partition coefficient as log Pow: 2.3
Vapour pressure, Pa at 20/C: 8
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish.
NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in October 2005. See section EU classification.
