体内負荷n-Butyl alcohol was identified, not quantified, in human blood(1) and mother's milk(2). n-Butyl alcohol was detected in human breath samples at concentrations of 1-10 ppb(3). The concentration of n-butanol in expired air from 8 individuals ranged from 1.3-35.0 ug/hr(4). n-Butyl alcohol was detected at concentrations of 0.02 and 0.08 ng/L in 2 samples of the expired air of 54 individuals(5). n-Butyl alcohol was detected at a mean concentration of 1.6 ug/cu m in the exhaled breath of Belgian workers exposed to a solvent mixture(6).
相互作用The effects of combined exposure to m-xylene and n-butyl alcohol on rotarod performance and motor activity in rats and respiratory rate in mice were investigated in the condition of an acute inhalation experiment. Rotarod performance and motor activity were tested in rats exposed to various concentrations of m-xylene, n-butyl alcohol and their mixture consisting of 50 Vol-% m-xylene and 50 Vol-% n-butyl alcohol immediately after termination of a 4-hour exposure period. The respiratory rate in mice was recorded in short 6 min duration exposures to individual solvents and their 50:50 Vol-% mixture. Both solvents and mixtures caused concentration-dependent disturbances of rotarod performance in rats. The medial effective concentration (EC50) for the effect amounted 6530 ppm, 1980 ppm and 3080 ppm for n-butyl alcohol, m-xylene and their mixture, respectively. Both solvents and their mixture changed the spontaneous motor activity in the rat. Because of a two-phase effect, the concentration-dependence of the observed changes could not be defined. The evaluation of the combined effect in motor activity test was carried out by comparing experimental values with expected ones assuming the summation of individual solvent effects. The tested solvents resulted in a concentration-dependent decrease in respiratory rate in mice. The concentration which decreased the respiratory rate to 50% (RD50) was 3010 ppm, 1360 ppm and 3140 ppm for n-butyl alcohol, m-xylene and their mixture, respectively...The activity of partially purified human erythrocyte acid phosphatase (eapase) was enhanced 4-fold by n-butanol. The extent of human prostatic acid phosphatase (papase) activation by n-propanol was lower than that of eapase. Eapase & papase activation by aliphatic alcohols, including n-butanol was noncompetitive.Potentiates bactericidal effects of alcohol, ethyl & alcohol, propyl.Pretreatment with n-butanol (10 mmol/kg i.p.) 30 minutes before alloxan (100 mg/kg) protects mice from the permanent hyperglycemic effects (measured at 72 hours) of the diabetogenic agent. This dose of n-butanol caused an elevation of serum glucose at 30 minutes, the time of alloxan administration. Since glucose administration can protect animals from alloxan, the possibility that alcohol-induced hyperglycemia protected mice from alloxan was investigated. Mannoheptulose, an antagonist of glucose action at the pancreatic beta-cell, when given 24 minutes after n-butanol and 6 minutes before alloxan, eliminated the alcohol-induced protection. Fasted mice did not exhibit n-butanol-induced hyperglycemia at 30 minutes and alloxan given at that time produced diabetes. No protection was observed in fed animals when n-butanol was given 5 minutes before alloxan. The high serum levels of butanol and normal serum glucose which were observed at 5 minutes after alcohol administration indicated that the lack of protection was not due to a lack of circulating alcohol but resulted from an absence of hyperglycemia. The results indicate that pretreatment with n-butanol protects mice from alloxan-induced diabetes by the indirect mechanism of producing hyperglycemia at the time of alloxan administration.

環境中動態TERRESTRIAL FATE: Based on a classification scheme(1), a measured Koc value of 3.2(2) indicates that n-butyl alcohol is expected to have very high mobility in soil(SRC). Volatilization of n-butyl alcohol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 8.81X10-6 atm-cu m/mole(3). n-Butyl alcohol is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7 mm Hg at 25 °C(4). n-Butyl alcohol biodegrades rapidly in screening tests using a sewage or activated sludge inoculum and is considered readily biodegradable(5). The biodegradation half-life of n-butyl alcohol in a sub-surface soil from Blacksburg, VA was approximately 7 days(6).AQUATIC FATE: Based on a classification scheme(1), a Koc value of 3.2(2) indicates that n-butyl alcohol is not expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected to be an important fate process(3) based upon a Henry's Law constant of 8.81X10-6 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 3.7 and 29, days respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process(SRC) since this compound lacks functional groups that hydrolyze under environmental conditions(3). n-Butyl alcohol biodegrades rapidly in screening tests using a sewage or activated sludge inoculum and is considered readily biodegradable(8). In a river die-away test, n-butyl alcohol achieved 33% of its theoretical BOD in 5 days(9), suggesting biodegradation may be an important fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-butyl alcohol, which has a vapor pressure of 7 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-butyl alcohol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC). The half-life for the reaction in air with hydroxyl radicals is estimated to be 45 hours(SRC), calculated from its rate constant of 8.5X10-12 cu cm/molecule-sec at 25 °C(3). n-Butyl alcohol 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).
食品調査値n-Butyl alcohol was identified, not quantified, in the volatile emissions of roasted filberts(1), raw beef(2), Frankfurter sausages(3) and roasted almonds(4). n-Butyl alcohol was detected in soybeans at concentrations of 199.9 to 1,586.2 ug/kg(5). The volatile emission rate of n-butanol from Bisbee apples harvested from the state of Washington was 8.6 to 35.1 picoliters/kg-hr(6). n-Butyl alcohol was detected in the volatile components of fish sauce(7). n-Butyl alcohol occurs as a product of fermentation of carbohydrates in alcoholic beverages and has been detected in the volatiles of various foods such as cheese, heat-treated milk, muskmelon, and cooked rice(8). n-Butyl alcohol has been qualitatively detected in beer, whiskey, grape and apple brandies and hop volatiles(9).

毒性の概要Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.orgIDENTIFICATION: n-Butyl Alcohol (BA) is an aliphatic alcohol with a rancid sweet odor, that is liquid at room temperature. n-Butyl Alcohol has numerous applications in the plastics and textile sector. It is ofen used as an industrial intermediate, converted into derivatives including butyl acetate and other butyl esters, which serve as solvents or monomer components in the production of artificial leather, textiles, safety glass, rubber cement, shellac, raincoats, photographic films, or perfumes. n-Butyl Alcohol can also be used directly as a solvent for paints, lacquers and varnishes, natural and synthetic resins, gums, vegetable oils, dyes and alkaloids. It is historically used as a solvent in nail care cosmetic products, and is also being used at low concentrations in eye makeup, personal hygiene, and shaving cosmetic products. n-Butyl Alcohol has been generally recognized as safe for use as a flavoring substance in food and appears on the 1982 Food and Drug Administration (FDA) list of inactive ingredients for approved prescription drug products. HUMAN EXPOSURE AND TOXICITY: Human exposure to n-butyl alcohol may occur in the workplace during manufacture and industrial/commercial use, and during consumer use of products containing n-butyl alcohol. Workers complained of ocular irritation, disagreeable odor, slight headache and vertigo, slight irritation of nose and throat, and dermatitis of the fingers and hands when the air concentration of n-Butyl Alcohol was greater than 50 ppm. Short term inhalation of n-butanol also produces a variety of CNS effects, including giddiness, ataxia, confusion, delirium, and possible coma. In high concentration in the air it can cause transient mild edema of conjunctiva of the eye, and a slightly reduced erythrocyte count. Inhalation toxicity studies in humans demonstrate sensory irritation of the upper respiratory tract, but only at levels above 3000 mg/cu m. n-Butyl Alcohol ingestion may result in vomiting, abdominal pain, headache, drowsiness and unconsciousness. Nail enamel containing 3% n-Butyl Alcohol resulted in no reactions. ANIMAL STUDIES: Animal studies demonstrate intoxication, restlessness, ataxia, prostration, and narcosis with exposure to n-butyl alcohol. High concentrations of n-Butyl Alcohol vapors can be fatal. Ocular irritation was observed for n-Butyl alcohol at 0.005 mL of a 40% solution. The behavioral no-effect dose for n-Butyl Alcohol injected subcutaneously (s.c.) was 120 mg/kg. Fetotoxicity has been demonstrated, but only at maternally toxic levels (1000 mg/kg). No significant behavioral or neurochemical effects were seen in offspring following either maternal or paternal exposure to 3000 or 6000 ppm. n-Butyl Alcohol was not mutagenic in the Ames tests and did not have any chromosome-damaging effects in a mouse micronucleus test. ECOTOXICITY STUDIES: BA exhibits low toxicity to fish, amphibians and aquatic invertebrates, plants, algae, bacteria and protozoans. However, some algal species are sensitive to BA. Acute toxicity to aquatic life may occur at concentrations greater than 500 mg/L.
