Occupational exposure limits
TLV: 10 ppm as TWA, 15 ppm as STEL; A3 (confirmed animal
carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: Carcinogen category: 3A; (DFG 2004).
PHYSICAL PROPERTIES
Boiling point: 72/C Relative vapour density (air = 1): 3.0
Melting point: -93/C Flash point: -8/C c.c.
Relative density (water = 1): 0.9 Auto-ignition temperature: 402/C
Solubility in water, g/100 ml at 20/C: 2.5 Explosive limits, vol% in air: 2.6-13.4
Vapour pressure, kPa at 20/C: 11.7 Octanol/water partition coefficient as log Pow: 0.73
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Other melting points: -100/C.
Use of alcoholic beverages enhances the harmful effect.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
The stabilizing quality of hydroquinone is limited to 60 days. For prolonged storage, another inhibitor, such as diphenylamine, is
recommended.
Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
