Combustible.DI-N-OCTYL PHTHALATE reacts 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 with caustic solutions. Flammable hydrogen may be generated by mixing with alkali metals and hydrides. Can generate electrostatic charges by swirling or pouring [Handling Chemicals Safely, 1980. p. 250].

  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Di-n-octyl phthalate, present at 100 mg/L, reached 67% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Di-n-octyl phthalate was degraded 92-94% in 7 days in a static degradation test utilizing a sewage seed that had been subcultured three times(2). In a model terrestrial-aquatic ecosystem, di-n-octyl phthalate was rapidly degraded by organisms in the system, having a half-life of 5 days(3). The degradation products of di-n-octyl phthalate are the monoester and phthalic acid(3); hydrolysis is believed to be accomplished by specific esterases only(4). Respirometric measurements of soil amended with di-n-octyl phthalate shows that when acclimated, there is some microbial utilization, although this is marginal at 4 and 10°C(4). When subjected to high-rate composting in an artificial compost mixture, 69% and 92% were removed after 7 and 30 days, respectively(5). Di-n-octyl phthalate was degraded 68.8% in model waste stabilization ponds(6). Di-n-octyl phthalate was biodegraded 85% after 10 days incubation in Rhine river water at 20°C; at 4°C, biodegradation was negligible(7). Di-n-octyl phthalate was biodegraded 61% in 42 days and 83% in 63 days in sandy soil and sandy soil mixed with gravel/till taken from a plasticizer manufacturing site(8). Di-n-octyl phthalate, at a starting concentration of 10-100 mg/L, had a half-life of 498.6 hours in acclimated activated sludge(9).

12.3 Bioaccumulative potential

After 24 hr exposure in a 3-day model ecosystem, mosquito fish (Gambusia affinis), Daphnia magna and snails (Physa) had BCFs of 1.16, 9426 and 438, respectively. However, in a 33-day model ecosystem, mosquito fish placed in the system on day 30 had a BCF of 9400. This discrepancy in the BCF for the 33 and 3 day ecosystem is most likely due to the fact that a final water concentration in the 33 day experiment was used in determining bioconcentration and due to the degradation of the di-n-octyl phthalate, this water concentration was low(1). According to a classification scheme(2), these BCFs suggest that bioconcentration in aquatic organisms is low to very high(SRC). Bioaccumulation factors of 28,500 and 6800 were determined in the algae, Oedogonium cardiacum, after 33 and 3 days exposure to di-n-octyl phthalate, respectively(3). Bioaccumulation factors of 2600 and 9300 were measured in brine shrimp after 33 and 3 days exposure to di-n-octyl phthalate, respectively(3). A BCF of 1606 was measured in algae exposed to di-n-octyl phthalate in a model waste stabilization pond(4). BCFs of 0-8.43 were reported for di-n-octyl phthalate in water spinach (Ipomoea aquatica) grown under different conditions on sludge from waste water treatment plants in China(5).

12.4 Mobility in soil

Log Koc values of 6.3(1), 4.38(2) and 5.22(3) were reported for di-n-octyl phthalate in soil. A mean sediment log Koc value of >5.0 was calculated from the mean di-n-octyl concentration in water and suspended particulate matter from Lake Yssel, The Netherlands(4). According to a classification scheme(5), these Koc values suggest that di-n-octyl phthalate is expected to be immobile in soil. Sedimentation accounted for 19.5% of the di-n-octyl phthalate loss from a model waste environmental pond(6).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 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.

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.
