Laboratory animals. NA The long-term effects of cyclohexane have not been adequately studied in laboratory animals. What is known is that cyclohexane causes skin irritation and eyelid infection, diarrhea, vascular damage, difficult breathing, liver degeneration, kidney disease (Bernard, et al. 1989, Malley, et al. 2000) (EPA 1994). Cyclohexane also causes neurological effects that include hyperactivity (Malley, et al. 2000) at lower doses and convulsions, tremors, decreased hearing function (Kreckmann, et al. 2000), and narcotic like-activity at high doses (EPA 1994). Fetal exposure to cyclohexane causes decreased infant weight (Kreckmann, et al. 2000).

Humans. In humans, cyclohexane is an eye and skin irritant and acts like a central nervous system depressant, causing dizziness and unconsciousness at high exposure levels. There is little to no information about the effects of long-term exposure in humans (EPA 1994).


Cyclohexane causes neurological, respiratory, gastrointestinal tract, liver, kidney, developmental, and cardiovascular toxicity in animals. Irritate the eyes and skin in humans.

Cyclohexane has been found in 9 of the 9 people tested in EWG/Commonweal studies.
