Produces no ill effects at normal temperatures, but may give off irritating vapors at high temperatures. (USCG, 1999)

This chemical is combustible. (NTP, 1992)

Use water spray, powder, alcohol-resistant foam, carbon dioxide.

Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Methods and materials for containment and cleaning up: Soak up with inert absorbent material and dispose of as hazardous waste. Keep in suitable, closed containers for disposal.

NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Storage class (TRGS 510): Non Combustible Liquids.

DI-ISONONYL PHTHALATE reacts exothermically with acids to generate isononyl 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].

AEROBIC: A shake flask CO2 evolution test using an inoculum prepared from soil and sewage, resulted in 99% biodegradation of diisononyl phthalate and 62% theoretical CO2 evolution after a 28 day incubation period(1). Diisononyl phthalate had a biodegradation half-life of 5.31 days with a 7.1 day lag time(1). Diisononyl phthalate was classified as slowly degradable in semi-continuous activated sludge test in which 32% degradation was achieved for a 3 ppm feed(2). In another semi-continuous activated sludge test (Soap and Detergent Association procedure), the mean percentage degradation for diisononyl phthalate (3 ppm) was 67.8% in 24 hr(2). In a die-away phase of the testing, it took 5 days to achieve 90% degradation(2). Using a modified Sturm test, diisononyl phthalate was biodegraded an average of 79% in 28 days(3). Diisononyl had degradation rates of 68 and >90% at initial concentrations of 1-3 and 3 ppm, in 1 and 4 days incubation time, respectively, using an activated sludge inoculum(4). Diisononyl phthalate exhibited a primary biodegradation to intermediates of >95% in 12 days from a starting concentration of 1 ppm using a fresh water inoculum(4). Ultimate biodegradation in fresh water sediment was <1 to 8% in 28 days with respective starting concentrations of 10 to 0.02 ppm(5). Total degradation of diisononyl phthalate with starting concentrations of 45, 35, and 100 ppm using activated sludge inoculum with a 28 day incubation period were 70, 57, and 71%, respectively(4). Diisononyl phthalate, present at 100 mg/L, reached 74% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(6).

An estimated BCF of 230 was calculated in fish for diisononyl phthalate(SRC), using an estimated log Kow of 9.37(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is 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(3).

Using a structure estimation method based on molecular connectivity indices(1), the log Koc of diisononyl phthalate can be estimated to be 5.52(SRC). Another estimated value is reported as 5.49(2). According to a classification scheme(3), these estimated Koc values suggest that diisononyl phthalate is expected to be immobile in soil.
