Toxicological Information
RTECS:
CAS # 110-54-3: MN9275000
LD50/LC50:
CAS # 110-54-3:
Draize test, rabbit, eye: 10 mg mild
Inhalation, mouse: LC50 = 150000 mg/m3/2H
Inhalation, rat: LC50 = 48000 ppm/4H
Inhalation, rat: LC50 = 627000 mg/m3/3M
Oral, rat: LD50 = 25 g/kg
Carcinogenicity:
CAS # 110-54-3: Not listed by IARC, NTP, ACGIH, or CA Prop 65
Epidemiology:
Occupational polyneuropathy has resulted from hexane exposures as low as 500 ppm, but the minimum levels of n-hexane that are neurotoxic in humans have not been established. Nearly continuous exposure of animals at 250 ppm has caused neurotoxic effects.
Teratogenicity:
No evidence of teratogenicity or embryotoxicity in animal studies with hexane has been found.
Fetotoxicity has been observed in the presence of maternal toxicity.
Reproductive:
Severe testicular damage has been observed in rats exposed to hexane at concentrations that have produced other significant toxicity. Although subneurotoxic doses of its principal toxic metabolite, 2,5-hexanedione, can induce progressive testicular toxicity in rats, there have been no reports of human sterility or other reproductive toxicity associated with n-hexane exposures.
Mutagenicity:
Positive results (chromosomal damage in the bone marrow cells) obtained for rats exposed by inhalation to n-hexane.
Neurotoxicity:
n-Hexane is a mild irritant and CNS depressant in acute exposure, but its principal effects are damage to the sensory and motor peripheral nerves, particularly in chronic exposure.
Ecological Information
Ecotoxicity: No data available. Estimated BCF values = 2.24 and 2.89. These values suggest that hexane will shoe low bioconcentration in aquatic organisms. Estimate Koc value = 4.11. This product will show slight soil mobility and is expected to rapidly volatilize from moist surface soils.
Environmental:
Terrestrial: Volatilization and adsorption are expected to be the most important fate processes.
Aquatic: Photolysis or hydrolysis is not expected to be important. Atmospheric fate: Expected to exist entirely in the vapor phase in ambient air. Expected half-life: 2.8 days. Expected to biodegrade but not to bioconcentrate.
Physical: No information available.
