Methyl Salicylate
Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic ester naturally produced by many species of plants, particularly wintergreens. The compound was first extracted and isolated from plant species Gaultheria procumbens in 1843. It can be manufactured synthetically and it used as a fragrance, in foods, beverages, and liniments. It forms a colorless to yellow or reddish liquid and exhibits a characteristic odor and taste of wintergreen. For acute joint and muscular pain, methyl salicylate is used as a rubefacient and analgesic in deep heating liniments. It is used as a flavoring agent in chewing gums and mints in small concentrations and added as antiseptic in mouthwash solutions. — DrugBank

- Environmental Bioconcentration: The log octanol/water partition coefficient for methyl salicylate is 2.55(1). The BCF estimated from this log Kow using a regression equation is 4 which indicates that the ester will not bioconcentrate in fish(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: If released on soil, methyl salicylate would readily leach. It would also be expected to partially volatilize from dry soil and photolyze on the soil surface. Based on the results of sceening tests, it would be expected to readily biodregrade. Chemical hydrolysis may be important in alkaline soil. (SRC) Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Methyl salicylate is readily biodegradable in screening tests and may be expected to biodegrade in surface waters. Methyl salicylate is expected to hydrolyze in water, the hydrolysis rate increasing with pH. At pH 7.5, its hydrolysis half-life is estimated to be 14.1 days(1,2,SRC). Methyl salicylate will react with singlet oxygen in natural surface waters resulting in a half-life of about 52 hr(3). Methyl salicylate absorbs UV radiation >290 nm and therefore may undergo direct photolysis under environmental conditions. Based on an estimated Henry's Law constant of 9.3X10-7 atm-cu-m/mol(4,5,SRC), a volatilization half-life of 49 days would be expected in a model river(SRC).

- Environmental Fate: ATMOSPHERIC FATE: Methyl salicylate reacts with photochemically-produced hydroxyl radicals in the atmosphere resulting in an estimated half-life of 1.4 days(1,SRC).
