IDENTIFICATION AND USE: Jasmone is a pale yellow, viscous liquid (oil). It is used in perfumery in fine jasmin bases and floral compositions. HUMAN EXPOSURE AND TOXICITY: Jasmone did not induce dermal sensitization in human volunteers. ANIMAL STUDIES: In an acute dermal toxicity study in 10 rabbits were give 5 g/kg cis-jasmone and observed for 14 days. Severe redness was seen in nine animals and moderate edema was observed in all animals. Eschar was found in two rabbits. Jasmone was not irritating or sensitizing in guinea pigs. In a rabbit eye irritation study, the highest dose group showed strong redness, strong secretion and edema, completely resolving by day 6. The remaining doses showed slight to moderate redness and secretion, completely resolving by day 3. Jasmone was not mutagenic in the Ames plate incorporation and pre-incubation assays with and without metabolic activation at concentrations up to 2500 ug/plate. The strains of Salmonella typhimurium used in the assays were TA98, TA100, TA102, TA1535 and TA1537. However, in a cytogenetic assay in Chinese hamster ovary (CHO) cells frequency of sister-chromatid exchanges (SECs) was significantly increased at concentrations of 33.3 uM and at 100 and 300 uM, the highest dose tested.

Jasmone is found in the volatile portion of oil from jasmine flowers(1). Jasmone is found in the essential oils of jasmine (3%), jonquil, and Pittosporam glabratum, in neroli oil, in peppermint (Mentha piperita), and in bergamont, apricot, raspberry, cinnamon, corn mint and spearmint oils, tea, and soybean(2).

Jasmone's production and use in perfumery for fine jasmine bases and floral compositions(1,2) and in the reconstitution of synthetic essential oils(3) may result in its release to the environment through various waste streams(SRC). Its use as a perfume(1) and potential use to protect plants against insect pests(4,5) will result in its direct release to the environment(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 295(SRC), determined from a structure estimation method(2), indicates that jasmone is expected to have moderate mobility in soil(SRC). Volatilization of jasmone from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.2X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(2). Even though the vapor pressure is low environmentally at standard temperature and pressure, 0.029 mm Hg(SRC), determined from a fragment constant method(2), there is a detectable odor; therefore, jasmone may volatilize from dry soil. Jasmone is bicyclic terpene and screening test results of other bicyclic terpenes indicate the compounds are generally biodegradable, but not readily biodegradable(3).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 295(SRC), determined from a structure estimation method(2), indicates that jasmone 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 2.2X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2.3 and 21 days, respectively(SRC). According to a classification scheme(4), an estimated BCF of about 100(SRC), from an estimated log Kow of 3.55(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Jasmone is bicyclic terpene and screening test results of other bicyclic terpenes indicate the compounds are generally biodegradable, but not readily biodegradable(5). Jasmone is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3). Jasmone is an olefin and olefins in surface waters exposed to sunlight react with photo-oxidants (such as hydroxyl radicals, peroxy radicals and singlet oxygen) with a half-life on the order of 25 days(6).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), jasmone, which has an estimated vapor pressure of 0.029 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase jasmone 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 2.4 hours(SRC), calculated from its rate constant of 1.6X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Vapor-phase jasmone is degraded in the atmosphere by reaction with ozone; the half-life for this reaction in air is estimated to be 0.5 hours(SRC), calculated from its rate constant of 6.1X10-16 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Vapor-phase jasmone is also degraded in the atmosphere by reaction with nitrate radicals; the half-life for this reaction in air is estimated to be 0.8 hours(SRC), calculated from a rate constant of 1.0X10-12 cu cm/molecule-sec at 24 °C(SRC) for analogous olefins(3). Jasmone contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight.

The rate constant for the vapor-phase reaction of jasmone with photochemically-produced hydroxyl radicals has been estimated as 1.6X10-10 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 2.4 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of jasmone with ozone has been estimated as 6.1X10-16 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(1); this corresponds to an atmospheric half-life of about 0.5 hours at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). Based on analogy to measured rate constants for similar olefins(2), the rate constant for the vapor-phase reaction of jasmone with nitrate radicals is on the order of 1X10-12 cu cm/molecule-sec at 25 °C(SRC); this corresponds to an atmospheric half-life of about 0.8 hours(SRC) at an atmospheric concentration of 2.5X10+8 nitrate radicals per cu cm(3). Jasmone is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(4). Jasmone contains chromophores that absorb at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight. Jasmone is an olefin and olefins in surface waters exposed to sunlight react with photo-oxidants (such as hydroxyl radicals, peroxy radicals and singlet oxygen) with a half-life on the order of 25 days(5).

An estimated BCF of about 100 was calculated in fish for jasmone(SRC), using an estimated log Kow of 3.55(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate, provided the compound is not metabolized by the organism(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of jasmone can be estimated to be 295(SRC). According to a classification scheme(2), this estimated Koc value suggests that jasmone is expected to have moderate mobility in soil.

The Henry's Law constant for jasmone is estimated as 2.2X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that jasmone is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 2.3 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 21 days(SRC). Jasmone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Even though the vapor pressure is low environmentally at standard temperature and pressure, 0.029 mm Hg(SRC), determined from a fragment constant method(2), there is a detectable odor; therefore, jasmone may volatilize from dry soil.

cis-Jasmone is found in apricot, raspberry, cinnamon, corn mint and spearmint oils, beer, tea, soybean and heated beans(1). cis-Jasmone was detected in the fragrant compounds of oolong tea(2).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 1,557 workers (276 of these were female) were potentially exposed to jasmone in the US(1). Occupational exposure to jasmone may occur through inhalation and dermal contact with this compound at workplaces where jasmone is produced or used. Monitoring and use data indicate that the general population may be exposed to jasmone via inhalation of ambient air, ingestion of food, and dermal contact with consumer products containing jasmone(SRC).

/HUMAN EXPOSURE STUDIES/ Repeated insult patch tests were conducted to determine if cis-jasmone would induce dermal sensitization in human volunteers. During the induction phase, 0.5 mL of 2% cis-jasmone in dimethyl phthalate was applied onto an occlusive patch and applied to the upper arm of each volunteer for 24 hr. Induction applications were made to the same site on Monday, Wednesday and Friday for a total of 9 applications during a 3-week period. Following a two week rest period, a challenge patch was applied to a site previously unexposed. Patches were applied as in the induction phase and kept in place for 24 hr before removal. Reactions to the challenge were scored at 48, and 72 hr after application. None of the 54 subjects tested experienced any sensitization reactions.|/HUMAN EXPOSURE STUDIES/ In the induction phase of a maximization study, 1 mL of an 8% cis-jasmone in petrolatum (5520 ug/sq cm) was applied under occlusion for 5 alternate-day 48-hr periods to the same site on the forearm of 25 adult male volunteers. The first induction application was preceded by a 24 hr treatment of 5% sodium lauryl sulfate. Following a 10-14 day rest period, a challenge concentration of 8% cis-jasmone in petrolatum was administered topically under occlusion for 48 hr to a different site on the back. The challenge dose was preceded by a 30 min application of 5% sodium lauryl sulfate. Scoring was done upon removal of the patch and 24 hr thereafter. There were no reactions in any of the subjects. In another study using the same protocol, except that a concentration of 2% sodium lauryl sulfate preceded the first induction application and no application of sodium lauryl sulfate preceded the challenge dose, there was no reaction in 21 adult male and female volunteers.
