Skin, Eye, and Respiratory Irritations
Octanol ... has caused transient injury of corneal epithelium, with recovery in 48 hr.
In a human patch test, 1-octanol in 2% petrolatum was neither a skin irritant nor a skin sensitizer.
Cleanup Methods
Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT let this chemical enter the environment.
AEROBIC: A number of aerobic biological screening studies, which utilized settled waste water, sewage, or activated sludge for inocula, have demonstrated that 1-octanol is readily biodegradable(1-8). Five day BOD tests show BODTs of 33(1), 37(2) and 62.4%(3). A ring test involving 14 laboratories found a mean degradation of 85% in 28 day test(4). A study which measured theoretical carbon dioxide evolved revealed 71% ultimate degradation of 1-octanol after an inoculation with activated sludge, in the dark, at 20 degrees C for 7 days(5). Other screening test data yielded a half-life of 22 hours(SRC) based on a first order biodegradation rate of 0.0313/hr(6) for 1-octanol.
ANAEROBIC: 1-Octanol was completely removed and lost 75% of the starting material during 49(1) and 56(2) day anaerobic acclimated studies.

10.3 Possibility of hazardous reactions

Combustible liquid when exposed to heat or flame...Attacks plastics [Handling Chemicals Safely 1980. p. 236]. Acetyl bromide reacts violently with alcohols or water [Merck 11th ed. 1989]. Mixtures of alcohols with concentrated sulfuric acid and strong hydrogen peroxide can cause explosions. Example: an explosion will occur if dimethylbenzylcarbinol is added to 90% hydrogen peroxide then acidified with concentrated sulfuric acid. Mixtures of ethyl alcohol with concentrated hydrogen peroxide form powerful explosives. Mixtures of hydrogen peroxide and 1-phenyl-2-methyl propyl alcohol tend to explode if acidified with 70% sulfuric acid [Chem. Eng. News 45(43):73. 1967; J, Org. Chem. 28:1893. 1963]. Alkyl hypochlorites are violently explosive. They are readily obtained by reacting hypochlorous acid and alcohols either in aqueous solution or mixed aqueous-carbon tetrachloride solutions. Chlorine plus alcohols would similarly yield alkyl hypochlorites. They decompose in the cold and explode on exposure to sunlight or heat. Tertiary hypochlorites are less unstable than secondary or primary hypochlorites [NFPA 491 M. 1991]. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: A number of aerobic biological screening studies, which utilized settled waste water, sewage, or activated sludge for inocula, have demonstrated that 1-octanol is readily biodegradable(1-9). Five day BOD tests show theoretical BODs of 33(1), 37(2) and 62.4%(3). A ring test involving 14 laboratories found a mean degradation of 85% in 28 day test(4). Biodegradation of 1-octanol was 71% after incubation in the dark at 20 degrees C for 7 days using an inoculation with activated sludge and measuring theoretical carbon dioxide evolved(5). Other screening test data yielded a half-life of 22 hours(SRC) based on a first order biodegradation rate of 0.0313/hr(6) for 1-octanol. 1-Octanol, present at 100 mg/L, reached 89% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(7).

12.3 Bioaccumulative potential

An estimated BCF of 44 was calculated in fish for 1-octanol(SRC), using a log Kow of 3.00(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

The Koc of 1-octanol is reported as 38(1). According to a classification scheme(2), this Koc value suggests that 1-octanol is expected to have very high mobility in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods


The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
