General First Aid:

(General first aid procedures)

To fight fire, use foam, carbon dioxide, dry chemical

Use water spray to cool unopened containers.

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

Use water spray to cool unopened containers.

Special hazards arising from the substance or mixture: Carbon oxides. Advice for firefighters: Wear self contained breathing apparatus for fire fighting if necessary.

Conditions for safe storage, including any incompatibilities: keep container tightly closed in a dry and well-ventilated place.

Separated from strong oxidants, strong reducing agents, chlorinated solvents, food and feedstuffs. Well closed. Ventilation along the floor.

Methods and materials for containment and cleaning up: sweep up and shovel. Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulation... Keep in suitable, closed containers for disposal...

Environmental precautions: prevent further leakage or spillage if safe to do so. Do not let product enter drains.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. 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 soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

Waste treatment methods: product: burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material.

Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.

Five tested plant volatile oils and their mixtures were evaluated for controlling the Margarodid, Icerya seychellarum seychellarum (Westw.) on growing Sago palms in Antoniades public gardens, Alexandria, Egypt. The tested volatile oils at concentration rates of 0.5, 1 and 1.5 % (v/v) were as follows: Camphor 20%; Dill 20%; Rose 30%; Peppermint 20% and Clove 30% (v/v). Their mixtures were Camphor/Peppermint; Camphor/Rose; at a rate of 1:1 Camphor/Rose/ Peppermint at 1:1:2 and Camphor/Rose/Dill at 2:1:1. The calculated results as general mean of residual reduction percent for the whole inspection periods of the test indicated that the superior volatile oils in reducing mealybugs were both Camphor and Rose, followed by Dill, Peppermint and the least efficient was Clove volatile oil. The evaluated volatile oils mixtures showed that each of Camphor/Rose/Peppermint, Camphor/Rose, and Camphor/Peppermint mixtures occupied a higher rank of efficiency against the treated mealybugs. /Mixture/

The aim of this work was to examine the antigenotoxic potential of plant monoterpenes: camphor, eucalyptol and thujone in prokaryotic and eukaryotic cells and to elucidate their effect on DNA repair. /The study/ compared the effect of monoterpenes on spontaneous, UV- and 4NQO-induced mutagenesis in Escherichia coli K12 repair proficient, and MMR and NER deficient strains. Positive controls tannic acid and vanillin were included in bacterial tests. /The study/ also examined protective effect of monoterpenes against 4NQO-induced genotoxicity in Vero cell line by alkaline comet assay. The results obtained in repair proficient strain indicated antimutagenic potential of monoterpenes against UV- and 4NQO-induced mutagenesis, which was diminished with NER deficiency. Camphor and eucalyptol maintained UV-induced SOS response longer than in controls, while thujone decreased SOS response and reduced general protein synthesis and the growth rate. The three monoterpenes increased spontaneous and UV-induced recombination in recA730 and camphor additionally in recA(+) cells. Incubation of 4NQO-pretreated Vero cells with monoterpenes resulted in significant reduction of tail moment. However, higher concentrations of monoterpenes induced DNA strand breaks. Obtained results indicate that by making a small amount of DNA lesions camphor, eucalyptol and thujone can stimulate error-free DNA repair processes and act as bioantimutagens.

...The radiation-induced SCE frequency was significantly low after a single dose of camphor (0.5 uM/g bw) administered 30, 45 or 60 min before irradiation; the effect was enhanced with increasing time intervals.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 117(SRC), determined from a structure estimation method(2), indicates that camphor is expected to have high mobility in soil(SRC). Volatilization of camphor from moist soil surfaces is expected to be an important fate process(SRC) given a an estimated Henry's Law constant of 8.30X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 0.65 mm Hg(3), and water solubility, 1.570X10+3 mg/L(4). Camphor is expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC). A 94% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is an important environmental fate process in soil(SRC). However, slow biodegradation has been observed in various aeration lagoons and wastewater treatment facilities(6,7).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 117(SRC), determined from a structure estimation method(2), indicates that camphor is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 8.30X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 0.65 mm Hg(4), and water solubility, 1.570X10+3 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 17 hours and 9 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 17(SRC), from a log Kow of 2.38(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 94% of theoretical BOD using activated sludge in the Japanese MITI test(8) suggests that biodegradation is an important environmental fate process in water(SRC). However, slow biodegradation has been observed in various aeration lagoons and wastewater treatment facilities(9,10). Camphor is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), camphor, which has a vapor pressure of 0.65 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase camphor 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 3.5 days(SRC), calculated from its rate constant of 4.6X10-12 cu cm/molecule-sec at 23 °C(2). Based on laboratory measurements, the atmospheric lifetime of camphor for reaction with ozone and nitrate radicals is estimated to be >235 days and >300 days respectively(3). Camphor absorbs at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).

The substance can be absorbed into the body by inhalation and by ingestion.

inhalation, skin absorption, ingestion, skin and/or eye contact

IDENTIFICATION AND USE: Camphor is a solid, translucent, white crystal with penetrating aromatic odor used as a rubefacient/counter-irritant medication. It is also used in liniments as a counter-irritant for fibromyalgia, neuralgia, and similar conditions. In dermatology, when it is applied as lotion (0.1 to 3%), it is an anti-pruritic and surface anesthetic (when applied gently, it creates a feeling of coolness). Camphor is no longer used as a pesticide in the US. Other uses of camphor include insect repellant use (particularly to control clothes moths); cosmetic ingredient. HUMAN EXPOSURE AND TOXICITY: The main target organs of camphor exposure are the CNS and kidneys. Convulsions, depression, apnea, asystole, gastric irritation, colic, nausea, vomiting, diarrhea, anxiety, excitement, delirium, and severe post-convulsive coma may occur after intake of camphor. The symptoms may appear 5 to 90 min after ingestion depending on the product ingested (solid or liquid). Poisoning by camphor is associated with an initial excitatory phase, with vomiting, diarrhea and excitement, followed by CNS depression and death. 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). There have been reports of instant collapse in infants after camphor has been applied to their nostrils. Camphor is irritating to the eyes, skin and mucous membranes. When camphor is applied on the skin, it is analgesic. Taken internally, it is an irritant and carminative /SRP: an agent used to reduce gas in the GI tract/. It has been used as a mild expectorant. Camphor is a CNS stimulant whose effects range from mild excitation to grand-mal convulsions or status epilepticus. These effects result from excitation of the cerebrum and lower structures of the CNS. Gastric irritation, together with cortical and medullary stimulation, frequently causes vomiting and diarrhea. It is not clear whether camphor toxicity is due to the parent compound, a metabolite (secondary alcohols, including borneol and isomers of hydroxy-camphor), or both. Camphor is used exclusively because of its local effects. When rubbed on the skin, it acts as a rubefacient and causes localized vasodilatation (mediated by way of an axon reflex), which gives feelings of comfort and warmth. As an anti-pruritic gent, when applied gently on the skin, it may create a feeling of coolness, and a mild, local anesthetic effect, which may be followed by numbness. When ingested in small amounts, it creates feelings of warmth and comfort in the stomach, but given in large doses it acts as an irritant. Camphor is not a human carcinogen, and the topical use of camphorated oil in pregnancy was not associated with teratogenic effects. However, camphor ingestion may lead to abortion and/or a death of the fetus because camphor crosses the placenta and fetuses lack the enzymes needed to hydroxylate and conjugate with glucuronic acid. ANIMAL STUDIES: Carcinogenicity tests in animals have been negative. Neuronal necrosis produced experimentally in mice by administration of multiple doses. In developmental studies, D-camphor elicited no evidence of teratogenicity when administered orally during the fetal period of organogenesis to pregnant rats at doses up to 1000 mg/kg bw/day, and to pregnant rabbits at doses up to 681 mg/kg bw/day. Camphor is not mutagenic with the Ames test but sister chromatid exchange has been reported in mice given 80 mg/kg doses of camphor ip, demonstrating possible genotoxicity.

Based on food consumption data collected on the French population by the Observatoire des Consommations alimentaires (OCA), the dietary exposure to camphor was estimated to be 1.5 mg/person/day(1). Assuming an average body weight of 60 kg, this corresponds to an exposure of 25 ug/kg bw/day(1).

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).

C - Cardiovascular system

QC - Cardiovascular system

Camphor is a naturally occurring compound that is used as a major active ingredient of balms and liniments supplied as topical analgesics. ... Capsaicin and menthol, two other topically applied agents widely used for similar purposes, are known to excite and desensitize sensory nerves by acting on two members of transient receptor potential (TRP) channel superfamily: heat-sensitive TRP vanilloid subtype 1 (TRPV1) and cold-sensitive TRP channel M8, respectively. Camphor has recently been shown to activate TRPV3, and here /investigators/ show that camphor also activates heterologously expressed TRPV1, requiring higher concentrations than capsaicin. Activation was enhanced by phospholipase C-coupled receptor stimulation mimicking inflamed conditions. Similar camphor-activated TRPV1-like currents were observed in isolated rat DRG neurons and were strongly potentiated after activation of protein kinase C with phorbol-12-myristate-13-acetate. Camphor activation of rat TRPV1 was mediated by distinct channel regions from capsaicin, as indicated by camphor activation in the presence of the competitive inhibitor capsazepine and in a capsaicin-insensitive point mutant. Camphor did not activate the capsaicin-insensitive chicken TRPV1. TRPV1 desensitization is believed to contribute to the analgesic actions of capsaicin. /The authors/ found that, although camphor activates TRPV1 less effectively, camphor application desensitized TRPV1 more rapidly and completely than capsaicin. Conversely, TRPV3 current sensitized after repeated camphor applications, which is inconsistent with the analgesic role of camphor. /Investigators/ also found that camphor inhibited several other related TRP channels, including ankyrin-repeat TRP 1 (TRPA1). The camphor-induced desensitization of TRPV1 and block of TRPA1 may underlie the analgesic effects of camphor.

In the liver microsomes of female mice, two induction phases during inhalation of DL-camphor were found. During the first 24 hr the apparent molar activity of the ethylumbelliferone dealkylase decreased. In the second phase, the molar ethylumbelliferone dealkylase activity was constant.

The metabolism of (+)-camphor and (-)-camphor was investigated in rabbits after administration /through/ stomach tube; metabolites of (+)-camphor were (+)-borneol, (+)-5-endo-hydroxycamphor, and (+)-3-endohydroxycamphor.

Camphor is rapidly oxidized to campherols (2-hydroxycamphor and 3-hydroxycamphor), and then conjugated in the liver to the glucuronide form. Camphor-related metabolites are relatively fat-soluble and may accumulate in fatty tissue.

Camphor is rapidly absorbed from the mucous membranes and the gastrointestinal tract. ... It is also absorbed through inhalation, through dermal application, and by nasal instillation.

... after camphor ingestion by mothers ... camphor was detectable in maternal blood 15 min after ingestion, but not after 8 hr. At delivery 36 hr later ... it was present in amnionic fluid, cord and fetal blood and fetal brain, liver and kidneys.

Alimentary absorption of pure camphor, or of alcohol solution ... is quite rapid, but from the oil preparation absorption is constant. Camphor is ... slowly absorbed from sc or im depots.

Absorbed camphor is mainly eliminated as the oxidized camphorol in the urine, although some appears in the breath, sweat, and feces.

... Orginally obtained commercially as the d-form from the camphor tree, Cinnamomum camphora T. Nees & Ebermeier, Lauraceae. Primarily manufactured from pinene as the racemate.

Steam distillation of camphor-tree wood and crystallization. This product is called natural camphor and is dextrorotatory. Synthetic camphor, most of which is optically inactive, may be made from pinene, which is converted into camphene; by treatment with acetic acid and nitrobenzene it becomes camphor, turpentine oil is also used.

Can be obtained from steam distillation of parts of the camphor tree; however it is usually made from alpha-pinene via camphene, to bornyl acetate, followed by saponification and oxidation

Natural camphor is obtained by distillation from the plants of Cinnamomum or Laurus camphora from China and Japan, together with corresponding essential oils; the raw camphor contains several impurities. It is separated from the water and the essential oil by pressure or by centrifugation and subsequently purified by sublimation or crystallization.
