    Diethyl phthalate (DEP) is a phthalate ester, namely the diethyl ester of phthalic acid. It is a clear substance that is liquid at room temperature and is only slightly denser than liquid water. It has a faint, disagreeable odor and can be transferred from the plastics that contain it. When burned, DEP produces toxic gases.
    Since the compound is a suitable solvent for many organic molecules, it is often used to bind cosmetics and fragrances. Other industrial uses include plasticizers, detergent bases and aerosol sprays. Because of the frequent dermal exposure of humans to the chemical, the question of toxicity is crucial. Several studies suggest that DEP can cause damage to the nervous system as well as to the reproductive organs in males and females.

    CombustibleDIETHYL 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. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].

    • Toxicity to algae: EC50; Species: Selenastrum capricornutum (Algae); Conditions: test temperature = 24+/-1 Deg C, pH was 7.6 at initiation and ranged from 7.9 to 8.9 on day 8; Concentration: 16 mg/L for 8 days (95% CI = 21.6 to 38.3); Effect: chlorophyll a percent change relative to control.
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: The aerobic half-life of diethyl phthalate in natural fresh water was estimated as 3 days(1). Diethyl phthalate was found to degrade to ethyl methyl phthalate, dimethyl phthalate, methyl phthalate and ethyl phthalate when co-contaminated with methanol(2). A shake flask experiment using microorganisms isolated from a municipal sludge resulted in complete aerobic degradation of 400 mg/L of diethyl phthalate in approximately 35 hours, 200 mg/L in 25 hours, 140 mg/L in 22 hours and 75 mg/L in 18 hours(3). Diethyl phthalate was completely degraded by Rhine River water at 20°C in a 3 day die-away test(4). Diethyl phthalate was 87-92% degraded in 10-50 days at 25°C from a concn of 100 mg/L using 30 mg/L activated sludge(5). Electrolytic respirometer studies have shown that diethyl phthalate is readily biodegradable under aerobic conditions(6-8). Diethyl phthalate had aerobic aquatic half-lives of 0.39 days in a river die-away test, 4.33 days in MITI test, and 0.71 days using microcosm periphlton, and an aerobic soil half-life of 1.83 days agitated in aqueous suspension(9).

    12.3 Bioaccumulative potential

    Bluegill sunfish exposed to 9.42 ug/L of diethyl phthalate for 21 days had a measured BCF of 117(1). According to a classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms is high(SRC). An experimental log BCF of 2.07 was measured in clams(3).

    12.4 Mobility in soil

    A Koc value of diethyl phthalate of 1,726 was measured in podzol soil at pH 2.8 and 4.85% carbon, a value of 704 in alfisol soil at pH 6.7 and 1.25% carbon, a value of 320 in sediment at pH 7.1 and 1.58% carbon(1). An experimental log Koc of 1.99 was determined from unsaturated soil columns at pH 4.8(2). A Koc value of 69 was determined from measurements on soil samples from Broome County, NY(3). According to a classification scheme(4), these Koc values suggest that diethyl phthalate is expected to have low to high mobility in soil.

    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.
