The toxicity and environmental properties of these naphthenic acids have been well studied recently due to their occurrence as a major contaminant jethanol water used for extraction of oil from tar sands. A WHO study concluded that p -menthanol was of “no safety concern” for human consumption at high levels of 2.


From Wikipedia, the free encyclopedia. CHM with a methylethyl or isopropyl substituent group at the same position as the methyl mrthanol in 4-methylcyclohexanemethanol cis 1-methylethyl cyclohexane methanol, CAS is regarded as a flavoring and fragrance agent, sometimes listed under the synonym p -menthanol, and was the subject of a review article on its toxicological and dermatological properties in However, a longer-term six-week repetition of that test as a sensitization study failed to produce any reactions.
