Anwendungen & Verwendung

Verwenden

Decyl Octyl Phthalate is an phthalate esters used as plasticizers and additives. Used in toxiciology studies as well as risk assessment studies of food contamination that occurs via migration of phthalates into foodstuffs from food-contact materials (FCM).

Sunset date 10/04/92.
Reactivity ProfileOCTYL DECYL 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.
Air and Water ReactionsInsoluble in water.
Hazard Classes and CategoriesSkin Irrit. 2 (100%)
Hazardous Reactivities and Incompatibilities... Can react vigorously with oxidizing materials.
BrandbekämpfungFire Extinguishing Agents Not to Be Used: Water.
Erste HilfeEYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Firefighting HazardsCombustible.
Freisetung ohne BrandSMALL SPILLS AND LEAKAGE: If you spill this chemical, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with alcohol followed by washing with a strong soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
EntsorgungsverfahrenSRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations.
Preventive MeasuresSRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
Personal Protective Equipment (PPE)Full impervious protective clothing, including boots and gloves. Where splashing is possible wear full face shield or chemical safety goggles. Use approved respirator to protect against vapors. (USCG, 1999)
Gesundheitliche AuswirkungenPhthalate esters are endocrine disruptors. Animal studies have shown that they disrupt reproductive development and can cause a number of malformations in affected young, such as reduced anogenital distance (AGD), cryptorchidism, hypospadias, and reduced fertility. The combination of effects associated with phthalates is called 'phthalate syndrome’. (A2883)
UmweltverhaltenTERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 6.6X10+5(SRC), determined from a structure estimation method(2), indicates that octyl decyl phthalate is expected to be immobile in soil(SRC). Volatilization of octyl decyl phthalate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.1X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(3). However, adsorption to soil is expected to attenuate volatilization(SRC). Octyl decyl phthalate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 3.9X10-7 mm Hg(SRC), determined from a fragment constant method(4). Biodegradation data were not available(SRC, 2008)however, biodegradation studies on a series of phthalate esters have demonstrated that phthalate esters in general are readily biodegraded(5).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 6.6X10+5(SRC), determined from a structure estimation method(2), indicates that octyl decyl phthalate is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 2.1X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 5.6 and 47 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 260 years if adsorption is considered (5). According to a classification scheme(6), an estimated BCF of 3(SRC), from an estimated log Kow of 9.52(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Hydrolysis is not expected to be an important process(SRC) based on estimated hydrolysis half-lives of 7.7 years and 280 days at pHs 7 and 8, respectively(9). Biodegradation data were not available(SRC, 2008)however, biodegradation studies on a series of phthalate esters have demonstrated that phthalate esters in general are readily biodegraded(10).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), octyl decyl phthalate, which has an estimated vapor pressure of 3.9X10-7 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase octyl decyl phthalate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 16 hours(SRC), calculated from its rate constant of 2.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase octyl decyl phthalate may be removed from the air by wet or dry deposition(SRC). Octyl decyl phthalate does contain chromophores that absorb at wavelengths >290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).
Unerwünschte WirkungenOccupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.

ToxizitätsübersichtPhthalate esters are endocrine disruptors. They decrease foetal testis testosterone production and reduce the expression of steroidogenic genes by decreasing mRNA expression. Some phthalates have also been shown to reduce the expression of insulin-like peptide 3 (insl3), an important hormone secreted by the Leydig cell necessary for development of the gubernacular ligament. Animal studies have shown that these effects disrupt reproductive development and can cause a number of malformations in affected young. (A2883)
Signs and SymptomsPhthalate esters are endocrine disruptors and can cause a number of developmental malformations termed 'phthalate syndrome'. (A2883)
Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc of octyl decyl phthalate can be estimated to be 6.6X10+5(SRC). According to a classification scheme(2), this estimated Koc value suggests that octyl decyl phthalate is expected to be immobile in soil.
Artificial Pollution SourcesOctyl decyl phthalate's production and use as a plasticizer for vinyl resins(1) may result in its release to the environment through various waste streams(SRC).
Environmental BiodegradationAlthough the biodegradation of octyl decyl phthalate was not studied, biodegradation studies on a series of phthalate esters have demonstrated that phthalate esters in general are readily biodegraded(1)
Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).
Environmental BioconcentrationAn estimated BCF of 3 was calculated in fish for octyl decyl 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).
Volatilization from Water/SoilThe Henry's Law constant for octyl decyl phthalate is estimated as 2.1X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that octyl decyl phthalate is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 5.6 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 47 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is about 260 years when adsorption is considered(3). Octyl decyl phthalate's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Octyl decyl phthalate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 3.9X10-7 mm Hg(SRC), determined from a fragment constant method(4).
