SECTION 10: Stability and reactivity
Reactivity
Reacts with strong oxidants. Decomposes on burning. This produces irritating fumes.
Chemical stability
no data available
Possibility of hazardous reactions
DI-ISOOCTYL PHTHALATE reacts exothermically with acids to generate isooctyl alcohol and phthalic acid. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges. [Handling Chemicals Safely, 1980. p. 250].
Conditions to avoid

Persistence and degradability
AEROBIC: Microorganisms isolated from raw sewage and sludge were capable of utilizing diisooctyl phthalate as a growth medium(1,2). Enriched microbial cultures obtained from sewage degraded 75% diisooctyl phthalate in 96 hours(2). A shake flask experiment employing an acclimated inoculum of soil, sewage and activated sludge degraded 99% of diisooctyl phthalate initially present over a 28 day incubation period(3). In a semi-continuous activated sludge test (Soap and Detergent Association procedure), the mean percentage degradation for diisooctyl phthalate was 84.5% in 24 hours(4). Diisooctyl phthalate incubated for 28 days in fresh water/sediment degraded 2, <1-10, and 4% at 12, 22, and 28 deg C, respectively(5).
Bioaccumulative potential
A measured BCF value of 207 was reported for Mosquito fish exposed to 6.4 mg/L of diisooctyl phthalate over an unspecified exposure period(1). According to a classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms is high, assuming the compound is not metabolized by the organism(SRC). However, bioconcentration studies on compounds which are structurally similar suggest that bioconcentration may be lower than that indicated by the regression-derived equations due to the ability of aquatic organisms to readily metabolize this class of compounds(3).
Mobility in soil
The Koc of diisooctyl phthalate is estimated as 1.6X10+4(SRC), using a water solubility of 0.09 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diisooctyl phthalate is expected to be immobile 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.
