A natural product found in Neolitsea daibuensis. It has a role as a metabolite. It is a fatty acid methyl ester and an octadecanoate ester. — ChEBI

- First Aid: EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.

- Environmental Bioconcentration: An estimated BCF of 29 was calculated for methyl stearate(SRC) using a log Kow of 8.35(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 62,000(SRC), determined from a structure estimation method(2), indicates that methyl stearate is expected to be immobile in soil(SRC). Volatilization of methyl stearate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 0.016 atm-cu m/mole(SRC), using a fragment constant estimation method(3). However, adsorption to soil is expected to attenuate volatilization(SRC). Methyl stearate is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.36X10-5 mm Hg(4). Methyl stearate is expected to rapidly biodegrade in aerobic soils as suggested by biodegradation in an aqueous biodegradation screening test(5). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 62,000(SRC), determined from a structure estimation method(2), indicates that methyl stearate is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 0.016 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Volatilization half-lives for a model river and model lake are 5 and 164 hours, respectively(SRC), using an estimation method(3). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column(SRC). The volatilization half-life from a model pond is estimated to be about 61 hours ignoring adsorption; when considering maximum adsorption the volatilization half-life increases to 17 months(5). According to a classification scheme(5), a /an estimated BCF of W29(SRC), from a log Kow of 8.35(10) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low.

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), methyl stearate, which has a vapor pressure of 1.36X10-5 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase methyl stearate 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 18 hours(SRC) from its estimated rate constant of 2.1X10-11 cu cm/molecule-sec at 25 °C(3). Particulate-phase methyl stearate may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
