Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.

Methods and materials for containment and cleaning up

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.

SECTION 7: Handling and storage

SECTION 10: Stability and reactivity


Flammable. Hydrolyzed by strong mineral acids and strong alkalis.

Chemical stability

no data available

Possibility of hazardous reactions

CombustibleDINONYL 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].

Persistence and degradability

AEROBIC: Dinonyl phthalate, added to a semi-continuous activated sludge apparatus at 5, 10, and 20 mg added per 24 hr, underwent 52%, 48%, and 54% degradation, respectively, under aerobic conditions(1,2). When dinonyl phthalate was incubated with pure cultures of Pseudomonas acidovorans under aerobic conditions, the initial degradation products were phthalic acid and nonyl alcohol(3). Di(heptyl,nonyl,undecyl) phthalate had a half-life of 6 to 8 days in river die-away tests(4). In active microcosms containing lake water and sediment, 40 to 48% of (14)C-di(heptyl,nonyl,undecyl)phthalate radioactivity was evolved as carbon dioxide over a 41 day period; after six weeks no residual (14)C-di(heptyl,nonyl,undecyl) phthalate was found in the water column and only 2 to 6% was associated with sediments(4). In semi-continuous activated sludge tests, a primary degradation half-life of <1 day at an addition rate of 5 to 200 mg/L per 24-hour cycle was observed for di(heptyl,nonyl,undecyl) phthalate(4). In shake flask studies using an acclimated bacterial inoculum, an ultimate biodegradation half-life of 5 days was observed for di(heptyl,nonyl,undecyl) phthalate at an initial concentration of 20 mg/L(4). 98% Biodegradation of di(heptyl,nonyl,undecyl) phthalate was observed over a period of 28 days in shake flask tests using an acclimated inoculum consisting of soil and sewage microorganisms(5).

Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for dinonyl phthalate(SRC), using an estimated log Kow of 9.52(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of dinonyl phthalate can be estimated to be 6.6X10+5(SRC). According to a classification scheme(2), this estimated Koc value suggests that dinonyl phthalate is expected to be immobile in soil. In sterile microcosms containing lake water and sediment, approximately 80% of di(heptyl,nonyl,undecyl) phthalate partitioned to sediment(3).

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.

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.
