Possibility of hazardous reactions
CombustibleDI-N-HEXYL PHTHALATE 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 can react with oxidizing materials and strong alkaline materials. (NTP, 1992)

Persistence and degradability
AEROBIC: In a shake flask carbon dioxide evolution screening test, loss of the parent compound (primary degradation) as well as carbon dioxide evolution (ultimate degradation) was measured using an acclimated inoculum of soil, sewage and activated sludge; >99% of dihexyl phthalate was lost and 77% of theoretical carbon dioxide was evolved after 28 days(1). Dihexyl phthalate had a half-life of 2.9 days with a 1.6 day lag(1). Dihexyl phthalate was degraded by activated sludge; although the units of the first order rate constant were omitted(2). In a semi-continuous activated sludge test (Soap and Detergent Association procedure), the mean percentage degradation for dihexyl phthalate was >92.8% in 24 hr(3). In the die-away phase of the testing, it took 1 day to achieve 90% degradation(3). An initial concentration of dihexyl phthalate of 25 mg/L was degraded 30 to 95% in fresh water after a 14 day incubation(4). Dihexyl phthalate at a starting concentration of 35 mg/L was biodegraded 80% after a 28 day incubation at 22 deg C(4). Dihexyl phthalate had an average aerobic biodegradation half-life of 9.7 days calculated in 6 river sediment samples taken from Taiwan rivers(5).
Bioaccumulative potential
An estimated BCF of 1,100 was calculated in fish for dihexyl phthalate(SRC), using a log Kow of 6.82(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(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(4).
Mobility in soil
The average Koc of (14)C-dihexyl phthalate using three standard USEPA sediments (supplied and characterized by the EPA) was measured at 5.26X10+5(1). According to a classification scheme(2), this Koc value suggests that dihexyl phthalate is expected to be immobile in soil.
Other adverse effects

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.
