SECTION 10: Stability and reactivity
Reactivity
Slightly soluble in water. Hydrolyzes slowly in contact with water (NTP, 1992).
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
The vapour is heavier than air.METHYL BENZOATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This compound reacts with strong oxidizing agents and strong bases and hydrolyzes slowly in contact with water. (NTP, 1992).
Conditions to avoid
no data available
Incompatible materials
Incompatible with strong acids, strong bases, nitrates, oxidizers.
Hazardous decomposition products
When heated to decomposition, it emites fumes containing CO and CO2.

SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Danio rerio (previous name: Brachydanio rerio) - 23 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: LC50 - Daphnia magna - 28.5 mg/L - 48 h.
- Toxicity to algae: EC50 - Desmodesmus subspicatus (previous name: Scenedesmus subspicatus) - 111.9 mg/L - 72 h.
- Toxicity to microorganisms: EC50 - activated sludge - 815 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
AEROBIC: Methyl benzoate, present at 28 mg/L in activated sewage sludge, achieved 62% biodegradation in 29 days using a Modified Sturm test measuring carbon dioxide evolution and is considered readily biodegradable(1).
Bioaccumulative potential
An estimated BCF of 12 was calculated in fish for methyl benzoate(SRC), using a log Kow of 2.12(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(SRC).
Mobility in soil
The adsorption of methyl benzoate was determined by a modified version of the OECD guideline 106, a batch equilibrium method, in three soils with different characteristics: an acid forest soil (Podzol), an agricultural soil (Alfisol), and a sediment. The respective Freundlich constants, Kf (1/n), for the three soils were 8.64 (0.81), 1.29 (0.85), and 1.51 (0.84)(1). Koc values for the Podzol, Alfisol and sediment were 178, 103, and 95, respectively(1). Methyl benzoate also has a reported log Koc value of 2.10 (Koc = 126)(2). Using a structure estimation method based on molecular connectivity indices(3), the Koc of methyl benzoate can be estimated to be 70(SRC). According to a classification scheme(3), methyl benzoate is expected to have moderate to high mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
