How is camphor made?

Camphor has been produced as a forest product for centuries, condensed from the vapor given off by the roasting of wood chips cut from the relevant trees, and later by passing steam through the pulverized wood and condensing the vapors. By the early 19th century most camphor tree reserves had been depleted with the remaining large stands in Japan and Taiwan with Taiwanese production greatly exceeding Japanese. Camphor was one of the primary resources extracted by Taiwan’s colonial powers as well as one of the most lucrative. First the Chinese and then the Japanese established monopolies on Taiwanese camphor. In 1868 a British naval force sailed into Anping harbor and the local British representative demanded the end of the Chinese camphor monopoly, after the local Qing representative refused the British bombarded the town and took the harbor. The "camphor regulations” negotiated between the two sides subsequently saw a brief end to the camphor monopoly. When its use in the nascent chemical industries ( discussed below) greatly increased the volume of demand in the late 19th century, potential for changes in supply and in price followed. In 1911 Robert Kennedy Duncan, an industrial chemist and educator, related that the Imperial Japanese government had recently (1907–1908) tried to monopolize the production of natural camphor as a forest product in Asia but that the monopoly was prevented by the development of the total synthesis alternatives, which began in "purely academic and wholly uncommercial" form with Gustav Komppa's first report "but it sealed the fate of the Japanese monopoly ] For no sooner was it accomplished than it excited the attention of a new army of investigators—the industrial chemists. The patent offices of the world were soon crowded with alleged commercial syntheses of camphor, and of the favored processes companies were formed to exploit them, factories resulted, and in the incredibly short time of two years after its academic synthesis artificial camphor, every whit as good as the natural product, entered the markets of the world […]." "...And yet artificial camphor does not—and cannot—displace the natural product to an extent sufficient to ruin the camphor-growing industry. Its sole present and probable future function is to act as a permanent check to monopolization, to act as a balance-wheel to regulate prices within reasonable limits." This ongoing check on price growth was confirmed in 1942 in a monograph on DuPont 's history, where William S. Dutton said, "Indispensable in the manufacture of pyroxylin plastics, natural camphor imported from Formosa and selling normally for about 50 cents a pound, reached the high price of $3.75 in 1918 [amid the global trade disruption and high explosives demand that World War I created]. The organic chemists at DuPont replied by synthesizing camphor from the turpentine of Southern pine stumps, with the result that the price of industrial camphor sold in carload lots in 1939 was between 32 cents and 35 cents a pound."

Why is camphor used in tool chests?

Solid camphor releases fumes that form a rust -preventative coating and is therefore stored in tool chests to protect tools against rust.

How is camphor released to the environment?

Camphor occurs in many plants and is released to the environment through emissions from various plant and tree species. If released to air, a vapor pressure of 0.65 mm Hg at 25 °C indicates camphor will exist solely as a vapor in the ambient atmosphere. Vapor-phase camphor will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.5 days. Camphor absorbs at wavelengths >290 nm and, therefore, may be susceptible to direct photolysis by sunlight. If released to soil, camphor is expected to have high mobility based upon an estimated Koc of 117. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 8.31X10-5 atm-cu m/mole. Camphor is expected to volatilize from dry soil surfaces based upon its vapor pressure. Utilizing the Japanese MITI test, 94% of the Theoretical BOD was reached in 4 weeks indicating that biodegradation is an important environmental fate process in soil and water. However, slow biodegradation has been observed in various aeration lagoons and wastewater treatment facilities. If released into water, camphor is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 17 hours and 9 days, respectively. An estimated BCF of 17 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. Occupational exposure to camphor may occur through inhalation of volatilized camphor and camphor dust as well as dermal contact with this compound at workplaces where camphor is produced or used. Monitoring data indicate that the general population may be exposed to camphor via inhalation of ambient and indoor air, ingestion of food and drinking water, and dermal contact with this compound and other consumer products containing camphor.

Where is camphor found in the air?

Camphor was detected as major emissions from Black Sage and California Sagebrush plants located in California's South Coast Air Basin (1). The normalized emission rate of camphor from mature spruce was 0.05 (Pinus glauca), 0.03 (P. abies), and 0.01 (P. pungens) ugC/g-hr (2). Camphor was detected in the emissions of 6 out of 63 vegetation species in forests near Atlanta, GA, Rhinelander, WI, and Hayden CO (3). The species that contained camphor were white spruce, north white cedar, Subalpine fir, big sagebrush, Englemann spruce, and Lodgepole pine. Measured camphor emission rates from these species ranged from less than 0.1 to 1.0 ug/hr-gr dry weight with an average rate of 0.3 ug/hr-gr dry weight during the summer of 1993 (3). Camphor has also been identified as a volatile emission from European fir (4).

How long does camphor last in the atmosphere?

Vapor-phase camphor will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.5 days. Camphor absorbs at wavelengths >290 nm and, therefore, may be susceptible to direct photolysis by sunlight.

How much camphor is toxic?

Toxic effects appear after the ingestion of approximately 2 g (lethal dose adults: 4 g, children: 0.5-1 g, infants: 70 mg/kg of pure camphor).

How to treat camphor intoxication?

Treatment of camphor intoxication is primarily supportive with a focus on airway management and seizure control. No antidotes are available. Activated charcoal should be administered for gastrointestinal decontamination, although its efficacy is doubtful. Due to prominent CNS effects, the induction of emesis is contraindicated. If liquid camphor is ingested, a nasogastric tube can be used to aspirate gastric contents before instillation of activated charcoal. Alcohols and oil solutions should be avoided because they have been reported to enhance absorption of camphor. Although not readily available, lipid hemodialysis and resin hemoperfusion have been reported to lower blood camphor concentrations in severely poisoned patients. Benzodiazepines such as lorazepam or diazepam are indicated for symptoms of CNS hyperactivity, such as agitation, tremors, and seizures. Phenobarbital can be used for recurrent or prolonged seizures.

What is camphor powder?

How many people are exposed to camphor?

NIOSH (NOES Survey 1981-1983) has statistically estimated that 153,554 workers (53,187 of these are female) are potentially exposed to camphor in the US (1). NIOSH has estimated that 427 workers (100 of these are female) are potentially exposed to camphor dust in the US (1). Dietary exposure to camphor arises from the consumption of foods flavored by using either herbs (e.g. basil, coriander, marjoram, rosemary, sage), their essential oils or the chemically defined flavoring substance d-camphor (2). Occupational exposure to camphor may occur through inhalation of volatilized camphor and camphor dust as well as dermal contact with this compound at workplaces where camphor is produced or used (SRC). Monitoring data indicate that the general population may be exposed to camphor via inhalation of ambient and indoor air, ingestion of food and drinking water, and dermal contact with this compound and other consumer products containing camphor (SRC).
