Fresh air, rest.

Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth.

Symptoms unlikely from any exposure. (USCG, 1999)

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

This study investigated the feasibility of using ozone-GAC process to remove phthalate esters from drinking water through a batch-scale study and adsorption isotherms. Dimethyl phthalate (DMP), diethyl phthalate (DEP) and dibutyl phthalate (DBP) were selected as the representative of phthalate esters. Results indicated that ozonation removes more than 40% DMP, DEP and DBP, GAC absorbed all the DMP, DEP and DBP that had not been oxidized by ozone at the condition of the Empty Bed Contact Time (EBCT) from 4 minutes to 12 minutes. The isotherms for GAC were successful correlated by Freundlich equation, and the date was used to estimate GAC service time. The results indicated that ozone-GAC process is a feasible way to remove DMP, DEP and DBP from drinking water.

Decomposes on burning. This produces irritating fumes.

Stable under recommended storage conditions.

Combustible.DIMETHYL 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 is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges by swirling or pouring [Handling Chemicals Safely, 1980. p. 250].

CLASSIFICATION: D; not classifiable as to human carcinogenicity. BASIS FOR CLASSIFICATION: Pertinent data regarding carcinogenicity data was not located in the available literature. HUMAN CARCINOGENICITY DATA: None. ANIMAL CARCINOGENICITY DATA: Inadequate. Classification based on former EPA guidelines

No information is available on the reproductive or developmental effects of dimethyl phthalate in humans. In one animal study, exposure to dimethyl phthalate via gavage had no effects on reproduction.

A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.

AEROBIC: After a 2.7 day lag, dimethyl phthalate was degraded in a shake-flask biodegradation test utilizing a soil/sewage inoculum with a half-life of 1.9 days(1). After 28 days, >99% of the dimethyl phthalate had disappeared and 86% mineralization had occurred(1). Dimethyl phthalate was completely degraded within 7 days in a static flask screening test with a wastewater inoculum(2). In two operating plants, 88 and 58% of the dimethyl phthalate was mineralized by the digested municipal sludge(3). In waste water treatment plants, essentially 100% removal resulting from biodegradation was reported(4-6). In a survey of publicly owned treatment works, an average removal of 97% was attributed to biodegradation(7). Dimethyl phthalate, present at 100 mg/L, reached 93% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(8). In activated sludge die-away tests and in a semi-continuous activated sludge test >90% and >81.0% degradation, respectively, was achieved in 1 day(9). Dimethyl phthalate removal of >96 to >99% was observed at the Cedar Creek Wastewater Reclamation - Recharge Facilities, Nassau County, NY(10). Dimethyl phthalate, at a starting concentration of 10-100 mg/L, was biodegraded 90% in 3 days and 100% in 5 days, and had a half-life of 21 hours in acclimated activated sludge from a coke plant waste water treatment system(11). Aerobic degradation studies indicated primary degradation for the lower molecular weight phthalate esters (including dimethyl phthalate) occurred rapidly, typically exceeding 90% degradation within a week, even if unacclimated inocula were used(12).

The mean BCF of dimethyl phthalate in sheepshead minnows was 5.4, after 24 hr(1). Bluegill sunfish showed a bioconcentration factor of 57(2) which may be elevated because only carbon-14 was measured in the experiment and metabolites may be included in the measurement of the parent compound(SRC). The depuration half-life was between 1 and 2 days(2). According to a classification scheme(3), these measured BCFs suggest that bioconcentration in aquatic organisms is low to moderate(SRC). The mean BCF of dimethyl phthalate in brown shrimp was 4.7, after 24 hr(1). Bioaccumulation factors of 3.1 and 6.3 were measured in shrimp (Peneaus aztecus) following 1 day of exposure(4). BCFs of 0.14-0.57 were reported for dimethyl phthalate in water spinach (Ipomoea aquatica) grown under different conditions on sludge from waste water treatment plants in China(5).

Dimethyl phthalate had a Koc of 55 in soil (89% sand, 11% silt/clay, 20% organic carbon) taken from Calumet, MI(1). Koc values ranging from 80 to 360 were calculated for dimethyl phthalate from its low carbon subsurface core sorption isotherms at different depths(2). Dimethyl phthalate had measured log Koc values of 1.88 to 1.89 in Typic Haplaquept type loamy, sandy soil(3). Dimethyl phthalate also had a reported Koc of 200(4) and log Koc value of 2.3(5). According to a classification scheme(6), these Koc values suggest that dimethyl phthalate is expected to have moderate to high mobility in soil(SRC). An average dimethyl phthalate removal of 79% was observed on a 14 m experimental overland flow slope(7). Relative to the average linear groundwater velocity, 18% retardation was calculated for dimethyl phthalate in a natural gradient tracer test using an unconfined sandy aquifer, assuming an organic carbon content of 0.05%(8). A mean sediment log Koc value of >5.2 was calculated from the mean dimethyl phthalate concentration in water and suspended particulate matter from Lake Yssel, The Netherlands(9). Adsorption of dimethyl phthalate is enhanced in the presence of salt: at a dimethyl phthalate concentration of 700 ug/L, 0.9 ug/g was adsorbed on suspended particulates in seawater, 0.6 ug/g was adsorbed on suspended particulates in 50% sea water, and <0.2 ug/g was adsorbed on suspended particulates in distilled water(10).

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.
