  • First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water.

  • NFPA Fire Rating: 2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.

  • Environmental Bioconcentration: An estimated BCF of 3.0 was calculated for cyclohexanol(SRC), using a log Kow of 1.23(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 11(SRC), determined from a log Kow of 1.23(2) and a regression-derived equation(3), indicates that cyclohexanol is expected to have very high mobility in soil(SRC). Volatilization of cyclohexanol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 4.40X10-6 atm-cu m/mole(4). Cyclohexanol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.657 mm Hg at 25 °C(5). In the Japanese MITI test, a 96% of theoretical BOD using activated sludge was reached in 4 weeks(6). Various other aerobic screening studies reported 5-day degradations ranging from 57% to 96% based on theoretical BOD in acclimated sewage inoculums or mixed microbial cultures(7-9). These data suggest that biodegradation is an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 11(SRC), determined from a log Kow of 1.23(2) and a regression-derived equation(3), indicates that cyclohexanol is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(4) based upon a Henry's Law constant of 4.40X10-6 atm-cu m/mole(5). Using this Henry's Law constant and an estimation method(4), volatilization half-lives for a model river and model lake are 8.4 days and 64 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3.0(SRC), from its log Kow(2) and a regression-derived equation(3), suggests the potential for bioconcentration in aquatic organisms is low(SRC). In the Japanese MITI test, a 96% of theoretical BOD using activated sludge was reached in 4 weeks(7). Various other aerobic screening studies reported 5-day degradations ranging from 57% to 96% based on theoretical BOD in acclimated sewage inoculums or mixed microbial cultures(8-10). These data suggest that biodegradation is an important environmental fate process in water(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), cyclohexanol, which has a vapor pressure of 0.657 mm Hg at 25 °C(2), will exist solely in the vapor phase in the ambient atmosphere. Vapor-phase cyclohexanol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 22 hrs(SRC), calculated from its rate constant of 1.7X10-11 cu cm/molecule-sec at 25 °C(3). Cyclohexanol does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
