10.1 Reactivity
no data available
10.2 Chemical stability
Stable under recommended storage conditions.
10.3 Possibility of hazardous reactions
Acidic salts, such as MONOSODIUM GLUTAMATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

12.2 Persistence and degradability
The following genera of bacteria have the enzymatic capability to degrade L-glutamic acid: Micrococcus, Brevibacterium, Corynebacterium, Arthrobacter and Microbacterium(1). Grab sample data, using radiolabeled monosodium glutamate and deep sea water and coastal estuarine water with their respective sediments, demonstrated that the glutamate ion should biodegrade rapidly in the environment(2). Samples were incubated for 19 days at temperatures from -1.5 to 1.5°C. Rates of uptake were measured with overall utilization of the substrate. At a concentration of 240 ug/120 mL, 5.46 ug monosodium glutamate/day was incorporated into the microbial population while a total of 16.07 ug/day were metabolized. At a concentration of 600 ug/120 mL, 12.0 ug monosodium glutamate/day was incorporated into the microbial population while a total of 40.15 ug/day were metabolized. At a concentration of 1200 ug/120 mL, 23.19 ug monosodium glutamate/day was incorporated into the microbial population while a total of 84.46 ug/day were metabolized. At a concentration of 3600 ug/120 mL, 36.76 ug monosodium glutamate/day was incorporated into the microbial population while a total of 123.46 ug/day was metabolized(2).
12.3 Bioaccumulative potential
An estimated BCF of 1 was calculated in fish for monosodium glutamate(SRC), using a water solubility of 3.85X10+5 mg/L(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).
12.4 Mobility in soil
The Koc of monosodium glutamate is estimated as 4(SRC), using a water solubility of 3.85X10+5 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that monosodium glutamate is expected to have very high mobility in soil.
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
