Fire Extinguishing Agents Not to Be Used: Water or foam may cause frothing.；Fire Extinguishing Agents: Alcohol foam, carbon dioxide, dry chemical (USCG, 1999)

Use water, dry powder, carbon dioxide, alcohol-resistant foam.

Fresh air, rest. Seek medical attention if you feel unwell.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

Rinse with plenty of water for several minutes (remove contact lenses if easily possible).

Rinse mouth. Rest. Do NOT induce vomiting. Seek medical attention if you feel unwell.

Wear self contained breathing apparatus for fire fighting if necessary.

Alcohol foam, carbon dioxide, dry chemical. Water or foam may cause frothing. Water may be ineffective on fire. Cool exposed containers with water.

Accidental Release Measures: ... Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.

Accidental Release Measures: ... Use protective equipment. Avoid dust formation. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust.

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:；Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. For Asbestos, avoid inhalation of dust. Cover spill with plastic sheet or tarp to minimize spreading. Do not clean up or dispose of, except under supervision of a specialist.；SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.；SMALL SPILL: Pick up with sand or other non-combustible absorbent material and place into containers for later disposal.；LARGE SPILL: Dike far ahead of liquid spill for later disposal. Cover powder spill with plastic sheet or tarp to minimize spreading. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2024)

SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.

Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Ventilation. Sweep spilled substance into sealable containers. If liquid: collect leaking liquid in containers. Absorb remaining liquid in inert absorbent. Then store and dispose of according to local regulations.

Precautions for handling: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:；IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.；SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.；FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

TERRESTRIAL FATE: Based on a classification scheme(1), reported Koc values of 2042-3388 in humic acid(2), indicate that 1-dodecanol is expected to have slight mobility in soil(SRC). Volatilization of 1-dodecanol from moist soil surfaces is expected(SRC) given a Henry's Law constant of 5.19X10-5 atm-cu m/mole(3). However, adsorption to soil is expected to attenuate volatilization(SRC). 1-Dodecanol is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 8.48X10-4 mm Hg at 25 °C(4). Theoretical BOD values using standard 5-day aerobic sewage tests ranged from 20-29.7%(5-7) indicate that biodegradation may be an important environmental fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), a reported Koc value of 7700 in suspended solids and 2337-11,184 in sediment(2), indicate that 1-dodecanol is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 5.19X10-5 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 27 hours and 12 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is about 11 months when adsorption is considered(5). 1-Dodecanol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). According to a classification scheme(6), an estimated BCF of 48(SRC), from its log Kow of 5.13(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Theoretical BOD values, using standard 5-day aerobic sewage tests ranged from 20-29.7%(9-11), indicate that biodegradation may be an important environmental fate process in water(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-dodecanol, which has a vapor pressure of 8.48X10-4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1-dodecanol 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 21 hours(SRC), calculated from its rate constant of 1.8X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). 1-Dodecanol 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).

IDENTIFICATION AND USE: 1-Dodecanol is used principally as chemical intermediate for salts of n-dodecyl sulfate and foam stabilizer for alcohol sulfate surfactants. It is also used in synthetic detergents, lube additives, pharmaceuticals, rubber, textiles, perfumes, and as a flavoring agent. The substance is practically non-toxic, and is a permitted food additive (GRAS) in both the U.S. and the EU. It is registered for pesticide use in the U.S. but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. HUMAN EXPOSURE AND TOXICITY: Contact for 48 hours with 4% 1-dodecanol in petrolatum was not irritating to 25 human volunteers, but marked skin irritation was noted when 25% 1-dodecanol in mineral oil was given in open contact with scarified skin of 5 to 10 volunteers once a day for 3 days. There was no skin sensitization in 25 human volunteers at a concentration of 4% in petrolatum. ANIMAL STUDIES: Aspiration of 0.2 mL of 1-dodecanol produced death among 9 out of 10 rats. The deaths were caused by pulmonary edema rather than cardiac arrest or respiratory failure as with the C3 to C10 alcohols. The lungs were dark red; seven rats died within 7 to 30 min, and two rats died 5 hr or longer after dosing. 1-Dodecanol did not cause developmental or reproductive toxicities when tested in rats at concentrations of 0, 100, 500, 2000 mg/kg /day for 14 days prior to mating. 1-Dodecanol, in the doses administered, had no effect on fetal weight, weight gain, food consumption, and food efficiency in the parental generation. When tested for carcinogenicity, 1-dodecanol showed weak tumor-promoting activity when applied three times a week for 60 weeks to the skin of mice that had previously received an initiating dose of dimethylbenz[a]anthracene. In another study, in 6-8 week old mice, ip injections of dodecanol in 0.1 mL tricaprylin (12.0 g/kg to 30 animals in high dose group, and 2.4 g/k

/AQUATIC SPECIES/ Although dodecanol exhibits non-polar narcotic toxicity to aquatic organisms of about 1 mg/L, the substance is readily degradable and releases during production, or through diffuse uses of the free alcohol do not give rise to environmental concerns.

/AQUATIC SPECIES/ Five month old Bluegill sunfish (average weight 0.63 grams, length 37 mm) acclimatized to test water for 24 hours prior to testing. Forty-eight hours before initiating the test the fish were taken off feed. Ten fish placed in each test vessel at concentrations of 0, 100, 180, 320, 560 and 1000 mg/L. No mortality was observed at 24, 48, or 96 hour intervals, except in the high dose fish at 96 hours, where mortality was 70%. Behavioral observations made during the test indicated that Bluegill sunfish exposed to 560 mg/L and higher exhibited abnormal surfacing behavior and became quiescent.

1-Dodecanol emission rates from green leaf composite samples and dead leaves were 96 ug/g and 44 ug/g, respectively(1).

Lauryl alcohol is a food additive permitted for direct addition to food for human consumption as a synthetic flavoring substance and adjuvant in accordance with the following conditions: a) they are used in the minimum quantity required to produce their intended effect, and otherwise in accordance with all the principles of good manufacturing practice, and b) they consist of one or more of the following, used alone or in combination with flavoring substances and adjuvants generally recognized as safe in food, prior-sanctioned for such use, or regulated by an appropriate section in this part.

Lauryl alcohol is an indirect food additive for use as a component of adhesives.

Residues of lauryl alcohol are exempted from the requirement of a tolerance when used in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest. Use: surfactant.

Section 4(g)(2)(A) of FIFRA calls for the Agency to determine, after submission of relevant data concerning an active ingredient, whether or not products containing the active ingredient are eligible for reregistration. The Agency has previously identified and required the submission of the generic (i.e., active ingredient-specific) data required to support reregistration of products containing aliphatic alcohols as an active ingredient. The Agency has completed its review of these generic data, and has determined that the data are sufficient to support reregistration of all products containing aliphatic alcohols (C6 - C16). The Agency has completed its assessment of the human health and ecological risks associated with the use of pesticide products containing aliphatic alcohols (C6 - C16). The Agency has determined that aliphatic alcohol-containing products are eligible for reregistration provided that label amendments are made as outlined in Chapter V. ... The Agency has identified eye-irritation concerns that warrant specific label language concerning personal protective equipment (PPE) and the length of restricted-entry intervals after application for tobacco uses of the aliphatic alcohols (C6 - C16). If all changes outlined in this document are incorporated into the product labels, the eye-irritation concerns will have been mitigated. Should a registrant fail to implement any of the reregistration requirements identified in this document, the Agency may take regulatory action to address these concerns.

New Active Ingredients ... includes pesticide active ingredients initially registered after November 1, 1984, that currently have active product registrations. By law, these newer pesticides are not subject to the reregistration program. They must, however, meet the new safety standard of the FQPA, and will be reviewed on a 15-year cycle under the registration review program. ... Active Ingredient Number: 001509; Type of Pesticide: biological - insect pheromone; Use Site: food use; Year: 1992.

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer safety standards, such as those described in the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern than those on List C, and with List C containing pesticides of greater concern than those on List D. Decanol is found on List D. Case No: 4004; Pesticide type: Insecticide, herbicide; Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the Reregistration Eligibility Decision (RED) document.; Active ingredient (AI): Decanol; Data Call-in (DCI) Date(s): 10/01/93; AI Status: All products containing this pesticide that were subject to reregistration have been cancelled. However, recently registered products contain this pesticide as a new active ingredient.

Frog liver microsomes catalyzed the hydroxylation of 1-dodecanol into the corresponding omega- and (omega-1)-hydroxy derivatives. The hydroxylation rate for 1-dodecanol was much lower than that for lauric acid. Both NADPH and O2 were required for hydroxylation activity. NADH had no effect on the hydroxylation. The hydroxylating system was inhibited 49% by CO at a CO:O2 ratio of 4.0. The formation of omega-hydroxydodecanol was more sharply inhibited by CO than was the formation of (omega-1)-hydroxydodecanol, implying that more than one cytochrome P-450 was involved in the hydroxylation of 1-dodecanol and that CO has a higher affinity for the P-450 catalyzing the omega-hydroxylation. The formation of laurate during the incubation of 1-dodecanol with frog liver microsomes suggests that a fatty alcohol oxidation system is also present in the microsomes. NAD+ was the most effective cofactor for the oxidation of 1-dodecanol and NADP+ had a little effect. Pyrazole (an inhibitor of alcohol dehydrogenase) had a slight inhibitory effect on the oxidation and sodium azide (an inhibitor of catalase) had no effect.

The liver microsomes of the Mongolian gerbil Meriones unguiculatus catalyzed the hydroxylation of various saturated fatty acids (C8-C18), alcohols (C12 and C16) and hydrocarbon (C12) to the corresponding omega- and (omega-1)-hydroxy derivatives. Lauric acid was hydroxylated most effectively among saturated fatty acids and the order of activity as hydroxylation substrates was C12 greater than C14 greater than C13 greater than C16 greater than C10 greater than C18 greater than C8. The specific activity of laurate hydroxylation (5.99 nmol/mg microsomal protein/min) in gerbil liver microsomes was higher than that observed in other species. 1-Dodecanol was also hydroxylated very effectively (4.58 nmol/mg microsomal protein/min) by gerbil liver microsomes, but in general the hydroxylation rates for fatty alcohols were much lower than those for the corresponding acids.

After 24-hr covered contact with the skin of mice, about 95% of a 100-uL dose of 0.5% 1-dodecanol in triethyl citrate remained on the skin. A small proportion, 0.1%, was recovered in the feces and urine, 0.13% was recovered from the body, and 2.61% was excreted in the air. These data indicate a low amount of dermal uptake.
