| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1.4(SRC), determined from a structure estimation method(2), indicates that 2-hydroxypropyl acrylate is expected to have very high mobility in soil(SRC). Volatilization of 2-hydroxypropyl acrylate from moist soil surfaces is not expected(SRC) given an estimated Henry's Law constant of 1.7X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). 2-Hydroxypropyl acrylate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.17 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). A 83% of Theoretical BOD using activated sludge in the Japanese MITI test(3) suggests that biodegradation is an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1.4(SRC), determined from a structure estimation method(2), indicates that 2-hydroxypropyl acrylate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 1.7X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). A hydrolysis half-life of >230 days at pH 7 for the commercial hydroxypropyl acrylate isomer mixture was reported, the hydrolysis half-life decreases with increase pH indicating that 2-hydroxypropyl acrylate may undergo slow hydrolysis under basic conditions(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow of 0.35(6) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low. The percent Theoretical BOD of the commercial hydroxypropyl acrylate isomer mixture reached 83% after 4 weeks in the Japanese MITI test(7) and 34.9% after 4 weeks in a closed bottle test for ready biodegradability(4). These results indicate that biodegradation will be an important fate process for 2-hydroxypropyl acrylate in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-hydroxypropyl acrylate, which has an estimated vapor pressure of 0.17 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-hydroxypropyl acrylate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals and ozone(SRC)the half-lives for these reactions in air are estimated to be 19 hours and 6.5 days(SRC), calculated from its respective rate constants of 2.0X10-11 and 1.7X10-18 cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(2). 2-Hydroxypropyl acrylate contains chromophores that absorb at wavelengths >290 nm(3) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). |

| Expositionspfade | The substance can be absorbed into the body through the skin and by ingestion. Serious local effects by all routes of exposure.inhalation, skin absorption, ingestion, skin and/or eye contact |
| Toxizitätsübersicht | IDENTIFICATION AND USE: 2-Hydroxypropyl acrylate (HPA) is a colorless liquid. It is used in manufacture of thermosetting resins for surface coatings. HUMAN STUDIES: There are no data available. ANIMAL STUDIES: Instillation of 0.1 mL in rabbit eye produced prompt, severe ocular irritation and corneal injury. In rabbits topical HPA application causes moderate burns (even when contacted as a 10% aqueous solution). Rats inhaling saturated HPA vapor generated at room temperature for 7 to 8 hours survived, but those exposed for 4 hours at approximately 650 ppm HPA vapor (generated at 100 °C) died either during exposure or within 1 hour after cessation of exposure. Marked signs of eye, nasal, and respiratory irritation were noted during the exposure period. When dogs were repeatedly exposed by inhalation at 5 ppm 6 hours/day, 5 days/week for a total of 20 or 21 days during a 1-month period, signs of ocular, nasal, and respiratory tract irritation were observed, and histologic testicular changes were seen in 3 of the 4 exposed animals. HPA was tested for mutagenicity in Salmonella typhimurium strains TA102 and TA2638 (with metabolic activation) and Escherichia coli strains WP2/pKM101 and WP2 uvrA/pKM101. It was found positive in the Escherichia coli strains. |

| ICSC Environmental Data | The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. |
| Soil Adsorption/Mobility | Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2-hydroxypropyl acrylate can be estimated to be 1.4(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-hydroxypropyl acrylate is expected to have very high mobility in soil. |
| Artificial Pollution Sources | 2-Hydroxypropyl acrylate's production and use in the manufacture of polymers and chemical intermediates(1) may result in its release to the environment through various waste streams(SRC). |
| Environmental Biodegradation | AEROBIC: Biodegradation data specific to 2-hydroxypropyl acrylate were not locatedhowever, results from ready biodegradation studies are available for the commercial hydroxypropyl acrylate isomer mixture which contains 75-80% 2-hydroxypropyl acrylate and 25-30% 1-methyl-2-hydroxyethyl acrylate(1-2). Hydroxypropyl acrylate, present at 100 mg/L, reached 83% of its Theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). Hydroxypropyl acrylate, present at 3 mg/L, reached 34.9% of its Theoretical OD after 4 weeks using a domestic activated sludge inoculum in the closed bottle test for ready biodegradability(2). In a similar test, hydroxypropyl acrylate was biodegraded 73% after 20 days(2). |
| Environmental Bioconcentration | An estimated BCF of 3 was calculated in fish for 2-hydroxypropyl acrylate(SRC), using a log Kow of 0.35(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. |
