SECTION 4: First aid measures
Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Produces no ill effects at normal temperatures but may give off irritating vapor at high temperature. (USCG, 1999)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Esters and related compounds

SECTION 9: Physical and chemical properties and safety characteristics
-
Physical state：
Di-n-octyl phthalate is a clear liquid with a mild odor. Slightly less dense than water and insoluble in water. Hence floats on water. Flash point 430°F. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. As a liquid, can easily penetrate the soil and contaminate groundwater and nearby streams. Eye contact may produce severe irritation and direct skin contact may produce mild irritation. Used in the manufacture of a variety of plastics and coating products.

Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
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].
Conditions to avoid

Incompatible materials
Incompatible materials: Strong oxidizing agents
Hazardous decomposition products
When heated to decomp it emits acrid smoke and irritating fumes.

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 deg 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 deg C; at 4 deg 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).
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).
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).
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.
