The acute dermal toxicity of
2,4,4-trimethylpentene was assessed in a group of 5 male and 5 female CD
rats exposed to 2000 mg/kg under an occlusive dressing for 24 hours.
Animals were observed daily and weighed weekly during a 14 days
observation period. There were no mortalities and no overt signs of
toxicity. The only treatment -related finding was vocalisation in all
animals 15 mins after application of the test material.
The acute dermal median lethal dosage (LD50)
of 2,4,4-trimethylpentene was greater than 2000 mg/kg. 2,2,4-trimethyl
pentene is considered to be of low dermal toxicity and
does not require classification under DSD or CLP.
