Racemic 2-ethylhexyl acrylate can be prepared with a high yield by esterification of acrylic acid with racemic 2-ethylhexanol in the presence of hydroquinone as a polymerization inhibitor and a strong acid such as methanesulfonic acid by reactive distillation using toluene as an azeotroping agent.[2]2-Ethylhexyl acrylate polymerizes easily. The polymerization can be initiated by light, peroxides, heat, or contaminants. It can react violently when combined with strong oxidants and can form explosive mixtures with air at temperatures above 82 °C (180 °F). The chemical, physical, and toxicological properties, however, can be greatly modified by additives or stabilizers.2-Ethylhexyl acrylate and butyl acrylate are the major base monomers for the preparation of acrylate adhesives. 2-Ethylhexyl acrylate can react by free-radical polymerization to form macromolecules having a molecular weight of up to 200,000 g/mol. Other monomers such as vinyl acetate, methyl acrylate, and styrene may be copolymerized to modify the properties of the resulting polymer.[3]2-Ethylhexyl acrylate can undergo free radical solution polymerization to yield its polymer. [1] It can form a series of copolymers via atom transfer radical copolymerization. [6] A study reports the emulsion terpolymerization of the product with styrene, methacrylic acid. [7] 2-ethylhexyl acrylate (EHA) is one of the constituents of acrylic polymeric latex. [2]It can undergo free-radical solution polymerization.[1] EHA is known to undergo free radical emulsion co- polymerization with methyl methacrylate (MMA) to form pressure-sensitive adhesives. [3][4] It may also form copolymers with acrylonitrile and acrylamide. [5]2-Ethylhexyl acrylate (HA) is the ester of acrylic acid and 2-ethyl hexanol. It is used as a raw material to make adhesives, coatings, construction materials, acrylic rubber, and emulsions.2-Ethylhexyl acrylate (HA) is the ester of acrylic acid and 2-ethyl hexanol.Our 2-ethylhexyl acrylate has very low-level impurities and may be used as a raw material for a wide variety of chemicals.2-Ethylhexyl acrylate (HA) is used as a raw material to make adhesives, coatings, construction materials, acrylic rubber, and emulsions.2-Ethylhexyl acrylate is produced from 2-ethyl hexanol and acrylic acid by catalytic dehydratisation in a continuous process. The spent lye of the aqueous work-up is treated in a waste water treatment plant. 2-Ethylhexyl acrylate is used as a monomer in the chemical industry for the production of polymers and copolymers, which are mainly processed further to aqueous polymer dispersions. The polymers and polymer dispersions are used in adhesives and as binders for paints. Other applications include coatings raw materials and uses in the plastics and textiles industries. In addition, 2-ethylhexyl acrylate is used as a monomer in construction-industry chemicals(e.g. floor coatings, road-marking substances) in concentrations between 0.1-21%. Releases of 2-ethylhexyl acrylate into the environment are expected to occur mainly during production and processing with waste water and exhaust gases.Based on the physical chemical properties of 2-ethylhexyl acrylate, the atmosphere is the main target compartment for distribution and only small amounts remain in the hydrosphere. Data on biotic or abiotic effects in the air compartment are not available. Because of the short half-life of 2-ethylhexyl acrylate in the atmosphere (about 19 hours) adverse effects are not to be expected. To evaluate whether the substance may cause toxic effects if accumulated in higher organisms through the food chain the classification on the basis of mammalian toxicity data can be used. 2-Ethylhexyl acrylate is not classified as Very Toxic or Toxic or Harmful and there are no adequate data from dietary toxicity tests which can be used for the determination of a PNECoral. Therefore a quantitative assessment of secondary poisoning can not be performed but improvement of the data basis is not of high priority for 2-ethylhexyl acrylate. A site specific release estimation representing a worst case situation for production,processing and use of 2-ethylhexyl acrylate was used to calculate the atmospheric deposition and the resulting concentration in the soil porewater in the vicinity of that site. A site specific release estimation representing a worst case situation for production,processing and use of 2-ethylhexyl acrylate was used to calculate the atmospheric deposition and the resulting concentration in the soil porewater in the vicinity of that site. 2-Ethyl Hexyl Acrylate is produced by reacting 2-ethyl hexanol and acrylic acid in a dehydratation process that acts as the catalyst. 2-Ethyl Hexyl Acrylate will react with oxidising agents such as alkalis and will polymerise when heated. Polymerisation is inhibited by hydroquinone.2-Ethyl Hexyl Acrylate is used in the chemical manufacturing industry for the production of homopolymers and co-polymers emulsion. It is used as a co-polymer for caulks, paint coatings, pressure sensitive adhesives (PSA) and sealants, leather finishing, paint additives, textiles and paper coatings. 2-ethyl hexyl acrylate also known as 2-Propenoic acid, 2-ethylhexyl ester; is an acrylate monomer with a molecular formula of C11H20O2, CAS: 103-11-7. It is a clear liquid which is not soluble in water and completely soluble in alcohols and ethers. It has a flashpoint between 75 – 90°C and has a characteristic acrylic odour.2-Ethylhexyl Acrylate (2-EHA ) is a highly versatile building block that readily copolymerizes with a wide variety of other acrylic and vinyl monomers to tailor specific high molecular weight copolymer properties for a diverse range of non-rigid applications.As a higher alkyl acrylate comonomer, 2-EHA imparts a glass transition temperature that is well below room temperature (homopolymer Tg is – 65 °C), flexibility and elasticity, and a hydrophobic nature. Unique features contributed to copolymer compositions include low temperature flexibility, water resistance, good weathering characteristics, and UV (sunlight) resistance. Primary applications that take advantage of these characteristics include multiple adhesives, especially pressure-sensitive adhesives (PSA), paint & coatings, caulks & sealants, textile & paper finishes, and printing inks.Because 2-EHA contributes to clarity, toughness, light & weather resistance, and chemical resistance, manufacturers can use acrylic copolymers containing 2-EHA in interior, exterior, basecoat and topcoat paint & coating formulations, and other related products.New areas of technical application for 2-EHA are in the homopolymer, poly(2-ethylhexyl acrylate), used as a plasticizer material for surface coatings, film, sheeting, and pressure-sensitive adhesives and tapes. As a plasticizer incorporated into PSAs, it results in an increase in peel strength, tack, and at the same time can improve removability. 2-EHA is used in superabsorbent copolymers to produce fast swelling and highly porous hydrogels for diapers and hygiene products.2-Ethylhexyl acrylate is a key monomer in a wide range of copolymer compositions. Free-radical polymerization techniques afford high monomer conversions and very high macromolecule molecular weights (>200,000). The ease of handling and co-polymerization of 2-EHA allow for use in emulsion, solvent, suspension and bulk polymerizations.BASF 2-Ethylhexyl Acrylate 2-Ethylhexyl acrylate 98% 2-Ethylhexyl acrylate forms homopolymers and copolymers. Copolymers of 2-Ethylhexyl acrylate can be prepared with acrylic acid and its salts, amides and esters, and with methacrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters and drying oils, etc. 2-Ethylhexyl acrylate is also a very useful feedstock for chemical syntheses, because it readily undergoes addition reactions with a wide variety of organic and inorganic compoundsToxicological Evaluation and Limit Values for 2-Ethylhexyl acrylate, Propylene carbonate, Quaternary ammonium compounds, Triglycidyl isocyanurate, and Tripropyleneglycol diacrylateDirect, acid-catalysed esterification of acrylic acid with 2-ethylhexanol is the principal method for the manufacture of 2-ethylhexyl acrylate. A polymerisation inhibitor is added. (IARC 1994).The major current use of 2-ethylhexyl acrylate is in acrylic pressure-sensitive adhesives. An adhesive for general purpose tape typically contains about 75% 2-ethylhexyl acrylate. Other uses of 2-ethylhexyl acrylate is in the production of plastics, latex, paints, textile and leather finishes, coatings for paper and industrial metal finishing. (HSDB 1999, IARC 1994).In Denmark, the principal use of 2-ethylhexyl acrylate is in UV curable inks, lacquers and varnishes. Emission occurs in the form of aerosols.2-Ethylhexyl acrylate is not known to occur as a natural compound. It may be released into the environment in fugitive and stack emissions or in wastewater during its production and use. (HSDB 1999, IARC 1994).2-Ethylhexyl acrylate is expected to exist almost entirely in the vapour phase based on its vapour pressure. It may photolyse in sunlight. It will react with photochemically produced hydroxyl radicals and ozone with an estimated half-life of 10.3 hours. (HSDB 1999).2-Ethylhexyl acrylate is not expected to adsorb to sediment or suspended particulate matter. It may hydrolyse, especially in alkaline waters based upon hydrolysis data for the structurally similar ethyl acrylate. It may photolyse in sunlight. It may biodegrade based upon the biodegradability of butyl acrylate and ethyl acrylate. It will significantly volatise from water with an estimated half-life of between 7.3 hours and 2.7 days. (HSDB 1999).2-Ethylhexyl acrylate is expected to exhibit moderate mobility in soil and, therefore, it may leach to groundwater. It may hydrolyse, especially in alkaline soils based upon hydrolysis data for the structurally similar ethyl acrylate. It may biodegrade based upon the biodegradability of butyl acrylate. It may volatilise from near surface soil and other surfaces. (HSDB 1999).According to HSDB (1999) 2-Ethylhexyl acrylate is not expected to bioconcentrate in aquatic organisms. However BUA (1994) is stating that considerable bioaccumulation is to be expected.The most probable route of human exposure of 2-ethylhexyl acrylate is by inhalation of contaminated air especially at plants where it is manufactured and used. Workers also may be exposed dermally during spills or leaks. (Samimi & Falbo 1982).In one study male Wistar rats were administrated an intravenous dose of 10 mg/kg bw of (14C)-2-ethylhexyl acrylate labelled on the vinyl carbons (Gut et al. 1988). In another study male Wistar rats were administrated an intravenous dose of 10 mg/kg bw or 50 mg/kg bw of (14C)-2-ethylhexyl acrylate (Cikrt et al. 1986). The highest concentrations of radioactivity in tissues was found in kidney, liver, brain, thymus and spleen.2-Ethylhexyl acrylate is believed to undergo carboxylesterase-catalysed hydrolysis to 2-ethylhexanol and acrylic acid, like other acrylate esters (Cikrt et al. 1986, Miller et al. 1981 – quoted from IARC 1994).2-Ethylhexyl acrylate to a minor extent reacts with non-protein SH groups in for instance glutathione causing depletion of the non-protein SH groups and excretion of thioethers in urine as described in the following studies:Male Wistar rats exposed by 6 hours inhalation to 2-ethylhexyl acrylate in concentrations from 250 to 4800 mg/m3 over 24 hours excreted thioethers in urine in a dose dependent manner decreasing from 8.0 to 3.0% (at 1000 mg/m3) of the dose of 2-ethylhexyl acrylate indicating saturable metabolism along this pathway. Dose related depletion of non-protein SH groups in blood, liver and brain was seen at concentrations of and above 2400 mg/m3. (Vodicka et al. 1990).When male Wistar rats were administrated an intraperitoneal dose of 10 mg/kg bw of (14C)-2-ethylhexyl acrylate labelled on the vinyl carbons 2% of the dose was found as thioethers in the urine (Gut et al. 1988).The principal eliminated metabolite in expired air was carbon dioxide in two studies in male Wistar rats given an intraperitoneal or intravenous dose of (14C)-2-ethylhexyl acrylate (Gut et al. 1988, Sapota 1988).When 2-ethylhexyl acrylate and its metabolite acrylic acid reacts with the reduced form of glutathion (GSH), mercapturic acids can be formed (Cikrt et al. 1986).2-Ethylhexyl acrylate is believed to undergo carboxylesterase-catalysed hydrolysis to 2-ethylhexanol and acrylic acid, like other acrylate esters (Cikrt et al. 1986, Miller et al. 1981 – quoted from IARC 1994).2-Ethylhexyl acrylate to a minor extent reacts with non-protein SH groups in for instance glutathione causing depletion of the non-protein SH groups and excretion of thioethers in urine as described in the following studies:Male Wistar rats exposed by 6 hours inhalation to 2-ethylhexyl acrylate in concentrations from 250 to 4800 mg/m3 over 24 hours excreted thioethers in urine in a dose dependent manner decreasing from 8.0 to 3.0% (at 1000 mg/m3) of the dose of 2-ethylhexyl acrylate indicating saturable metabolism along this pathway. Dose related depletion of non-protein SH groups in blood, liver and brain was seen at concentrations of and above 2400 mg/m3. (Vodicka et al. 1990).When male Wistar rats were administrated an intraperitoneal dose of 10 mg/kg bw of (14C)-2-ethylhexyl acrylate labelled on the vinyl carbons 2% of the dose was found as thioethers in the urine (Gut et al. 1988).The principal eliminated metabolite in expired air was carbon dioxide in two studies in male Wistar rats given an intraperitoneal or intravenous dose of (14C)-2-ethylhexyl acrylate (Gut et al. 1988, Sapota 1988).When 2-ethylhexyl acrylate and its metabolite acrylic acid reacts with the reduced form of glutathion (GSH), mercapturic acids can be formed (Cikrt et al. 1986).Male Wistar rats were administrated an intravenous dose of 10 mg/kg bw or 50 mg/kg bw of (14C)-2-ethylhexyl acrylate. Biliary excretion of radioactivity was followed in 1-3 hour intervals within the first 24 hours after administration. A significant increase in bile flow (243%) was observed. In the 24-hours 2.2% of the dose was eliminated via bile at both doses, most of it (83%) during the first 3 hours. (Cikrt et al. 1986).Seven persons have developed allergic contact dermatitis due to an acrylic based adhesive tape. Patch-testing revealed that all persons reacted to 2-ethylhexyl acrylate. Five of the persons were further tested for cross-sensitisation patterns. They all reacted to 2-ethylbutylacrylate and some of them reacted to other acrylates as well. (Jordan 1975).In Finland, 5 cases of occupational contact urticaria caused by 2-ethylhexyl acrylate has been reported from 1990 to 1994 (Kanerva et al. 1996 – quoted from Toxline pre1981-1999).When rats were exposed to a saturated atmosphere (about 1400 mg/m3) of 2-ethylhexyl acrylate for 8 hours no mortality occurred (BASF 1958 – quoted from IUCLID 1996).Alderley Park rats (2 animals of each sex per group) were exposed to 2-ethylhexyl acrylate in ethanol at 375 and 1000 mg/m3 6 hours a day, 5 days per week for 2½ week. A reduced body weight gain, lethargy, and dyspnoea were observed in high-dose animals. No changes in blood, urine and pathology were observed. Low-dose animals showed no toxic signs. (Gage 1970 – quoted from IUCLID 1996).The reported oral LD50-values for 2-ethylhexyl acrylate ranged from 4.4 to 12.8 g/kg for rats (5 values reported), and from 4.4 to greater than 5.0 g/kg for mice (2 values reported). Rabbits have an oral LD50-value greater than 3.5 g/kg and the value for cats is greater than 1.8 g/kg (1 value reported for each species). (Studies quoted in IUCLID 1996, Clayton & Clayton 1994, DPIMR 1981, BUA 1994).Rabbits (1 animal per sex) were fed 2-ethylhexyl acrylate as a 10% emulsion through a tube at a dose of 1774 mg/kg for 6 days (male) or 8 days (female). Four female rabbits were fed a dose of 887 mg/kg for 10 days. The high-dose animals died after 6 or 8 days. A reduced body weight gain, lack of desire to eat, and weak muscle tonus were observed and the gastric mucosa and kidneys were damaged. Low-dose animals only showed momentary lack of desire to eat and a slightly reduced body weight gain. (BASF 1960 – quoted from BUA 1994).Female Dunkin Hartley outbred guinea pigs were induced with intradermal injections of 2-ethylhexyl acrylate in concentrations of 0.5 M or 0.17 M in Freund´s complete adjuvant three times during 9 days. Sensitisation was observed when the animals were challenged at day 21, 35 and 49 with 1 M 2-ethylhexyl acrylate applied epicutaneously. At an induction concentration of 0.5 M 6-11 out of 16 animals were sensitised. At an induction concentration of 0.17 M 11-13 out of 16 animals were sensitised. Four control animals were sensitised (3 at day 35 and 1 at day 49). Cross reaction was seen with ethyl acrylate, n-butyl acrylate and hexyl acrylate. (Waegemaekers & van der Walle 1983).Guinea pigs were induced with 0.1% (w/v) 2-ethylhexyl acrylate applied epicutaneous or intracutaneous 3 times a week for 3 weeks. Sensitisation was observed when the animals were challenged at day 11 after the induction with the same concentration of 2-ethylhexyl acrylate as used for the induction. For the epicutaneous test, 10 out of 10 animals were sensitised. For the intracutaneous test, 7 out of 10 animals were sensitised. (Hunter et al. 1966 – quoted from Nordisk Ministerråd 1991).In the Polak method, 6 Hartley outbred guinea pigs of either sex were induced with 1 mg 2-ethylhexyl acrylate in Freund´s complete adjuvant applied as injections in the footpads and the neck. Sensitisation was observed when the animals were challenged at day 7 after the induction with 1% or 5% 2-ethylhexyl acrylate. (Parker & Turk 1983).There was an apparent increase in the frequency of chronic nephritis in C3H/HeJ mice (68%) treated three times a week for their lifetime with 20 mg 75% (v/v) 2-ethylhexyl acrylate in acetone applied to clipped dorsal skin compared to the negative control (15%). Survival was not affected by the treatment with 2-ethylhexyl acrylate. (DePass et al. 1985).Male NMRI and C3H/HeJ mice (10 animals per group) exposed to doses of 25ml 21% or 86.5% 2-ethylhexyl acrylate in acetone 3 times a week for 3 months exhibited skin irritation. The NMRI mice were less sensitive than the C3H/HeJ mice. No skin irritation were observed for the NMRI mice given 21% 2-ethylhexyl acrylate. (BASF 1985 – quoted from IUCLID 1996).In long term (2 years or for life) carcinogenicity studies with 2-ethylhexyl acrylate applied to NMRI or C3H/HeJ mice (80 animals per group) 3 times a week, skin irritation (scaling, scabbing, hyperkeratosis, hyperplasia, crust formation and ulceration) was observed. Survival were not affected by the treatment with 2-ethylhexyl acrylate and no systemic effects were seen. (Mellert et al. 1994, Wenzel-Hartung et al. 1989). The lowest dose administered to the C3H/HeJ mice was 25 ml of a 2.5% (w/w) solution of 2-ethylhexyl acrylate in acetone. Skin irritation was observed at this dose, however, after the 11th week of treatment, these lesions were reversible. One group of C3H/HeJ mice was treated with a 43% solution for 24 weeks and thereafter observed for lifetime. Skin lesions were reversible in the 43% group immediately after treatment was stopped. For the higher doses (21% and 86.5%) further skin lesions developed. (Wenzel-Hartung et al. 1989).Male and female New Zealand white rabbits (2 or 1 animals of each sex) exposed to 1 ml per day of 2-ethylhexyl acrylate for 3 or 12 days developed skin inflammation. After 12 days necroses and ulcerations were also observed. (Hunter et al. 1981 – quoted from IUCLID 1996).Male and female guinea pigs (5 animals of each sex) exposed to 0.5 ml per day of 2-ethylhexyl acrylate for 12 days developed skin inflammation, necroses and ulcerations. The lesions were worse than the lesions seen in rabbits exposed to the double dose of 2-ethylhexyl acrylate. (Hunter et al. 1981 – quoted from IUCLID 1996).2-Ethylhexyl acrylate was not mutagenic in 4 strains (TA98, TA100, TA1535, and TA1537) of Salmonella typhimurium in an Ames test with or without metabolic activation systems (Zeiger et al. 1985).2-Ethylhexyl acrylate tested in cultured L5178Y mouse lymphoma cells without exogenous activation produced an equivocal result for an increased mutant frequency as well as for induced aberrations. No increase in the number of micronuclei was seen. (Dearfield et al. 1989).In another experiment the mutation frequency was up to 4.6 times greater than in controls for the highest dose levels of 2-ethylhexyl acrylate added to cultured L5178Y mouse lymphoma cells with metabolic activation. No reproducible increase in mutation frequency was seen without the metabolic activation. (Litton Bionetics 1984 – quoted from HSDB 1999).2-Ethylhexyl acrylate did not induce a dose-related increase in the hgprt mutant frequency in either the suspension or monolayer assay in Chinese hamster ovary cells (Moore et al. 1991).A cell transformation assay in C3H-10T1/2 cells tested negative with 2-ethylhexyl acrylate (BASF 1982 – quoted from IUCLID 1996).The sister chromatid exchange assay in CHO cells with and without metabolic activation was slightly positive when tested with 2-ethylhexyl acrylate with metabolic activation (ambiguous result) (BASF 1980 – quoted from IUCLID 1996).Unscheduled DNA synthesis in primary rat hepatocytes was slightly increased when tested with 2-ethylhexyl acrylate (ambiguous result) (BASF 1980 – quoted from IUCLID 1996).No chromosome aberrations were observed when mice were given an oral dose of 2.5 g/kg once a day for 1 or 5 days in an in vivo cytogenetic assay (BASF- quoted in IUCLID 1996).In a 2-year carcinogenicity study 25 ml of a 21.5, 43 or 85% (w/w) solution of 2-ethylhexyl acrylate in acetone was applied epicutaneously to the clipped dorsal skin of male NMRI mice (80 per group) three times a week. After about 7 months half of each group was rested for treatment for 2 months and then treated with a promoter for 20 weeks. None of the mice treated with 2-ethylhexyl acrylate alone developed a skin tumour at the application site. One squamous cell papilloma occurred in each of the groups treated with 2-ethylhexyl acrylate and the promoter. Squamous cell carcinomas were observed only in the positive control groups (exposed to 0.015 % benzo[a]pyrene alone or in combination with promoter). (Mellert et al. 1994).In a lifetime carcinogenicity study 25 ml of a 2.5, 21 or 86.5% (w/w) solution of 2-ethylhexyl acrylate in acetone was applied epicutaneously to the clipped dorsal skin of male C3H/HeJ mice (80 per group) three times a week. Another group was treated with a 43% solution for 24 weeks and thereafter observed for lifetime. Only in the 86.5% and 21% test groups showing chronic irritative skin damage there was a high incidence of neoplastic skin lesions (total of 15 papillomas, 36 carcinomas, and 16 melanomas) with no dose dependency. In contrast, no skin tumours were found in the negative control groups, in the group treated with 2.5% 2-ethylhexyl acrylate for lifetime or in the group treated with 43% 2-ethylhexyl acrylate for about 6 months and then observed for lifetime. (Wenzel-Hartung et al. 1989).In a lifetime carcinogenicity study 20 mg of a 75% (v/v) solution of 2-ethylhexyl acrylate in acetone was applied epicutaneously to the clipped dorsal skin of 40 male C3H/HeJ mice three times a week. The concentration was chosen as the highest concentration that caused neither grossly observable irritation nor reduced weight gain in a preliminary 2-week study. Two animals had squamous cell carcinomas and four additional animals had squamous cell papillomas all on the treated skin. (DePass et al. 1985).2-Ethylhexyl acrylate is a colourless liquid with a sharp, musty odour. Its solubility in water is low (0.1g/l). Its vapour pressure is 0.14 mmHg. The odour threshold in air is 0.55-1.36 mg/m3.In Denmark, the principal use of 2-ethylhexyl acrylate is in UV curable inks, lacquers and varnishes.2-Ethylhexyl acrylate is not known to occur as a natural compound. It may be released into the environment in fugitive and stack emissions or in wastewater during its production and use.If released to the atmosphere, 2-ethylhexyl acrylate will react with photochemically produced hydroxyl radicals and ozone with an estimated half-life of 10.3 hours. It may also photolyse in sunlight.If released to soil and water, 2-ethylhexyl acrylate may biodegrade and it may hydrolyse, especially in an alkaline environment. 2-Ethylhexyl acrylate is not expected to adsorb to sediment or suspended particulate matter in water. It is expected to exhibit moderate mobility in soil. 2-Ethylhexyl acrylate will significantly volatise from water and near surface soil with an estimated half-life of between 7.3 hours and 2.7 days.In the rat 2-ethylhexyl acrylate is readily absorbed through the gastrointestinal tract and after intraperitoneal application. The plasma radioactivity concentration peaked at 2-3 hours. Following absorption 2-ethylhexyl acrylate is distributed to various organs with the highest concentration occurring in the liver and kidney. 2-Ethylhexyl acrylate is rapidly metabolised and excreted. At high doses (100 mg/kg bw) the decline in concentration in the tissues was slower with levels remaining almost constant for 72 hours in adipose tissue. 2-Ethylhexyl acrylate is believed to undergo carboxylesterase-catalysed hydrolysis to alcohol and acrylic acid, like other acrylate esters. 2-Ethylhexyl acrylate to a minor extent reacts with non-protein SH groups resulting in thioethers and mercapturic acids being excreted in the urine and/or bile. The major route of excretion is the lungs (50-75%) followed by urine (7-41%) and faeces (0.01-3 %). The metabolite in the lungs is CO2.Seven cases of allergic contact dermatitis due to an acrylic based adhesive tape have been reported. Patch-testing revealed that all persons reacted to 2-ethylhexyl acrylate. No cases have been reported of respiratory sensitisation. In Finland 5 people have got contact urticaria due to 2-ethylhexyl acrylate.Single peroral, dermal or inhalatory administration of 2-ethylhexyl acrylate each proved to be only slightly toxic (LC50-value for mice is greater than 7700 mg/m3; oral LD50-values ranged from 1.8 to 12.8 g/kg for different species; and dermal LD50-values ranged from 7.5 to 16 g/kg for different species).When rats were inhaling about 1400 mg/m3 of 2-ethylhexyl acrylate for 8 hours no mortality occurred.A reduced body weight gain, lethargy, and dyspnoea were observed in Alderley Park rats inhaling 2-ethylhexyl acrylate at 1000 mg/m3 6 hours a day, 5 days per week for 2½ week. Animals inhaling 375 mg/m3 for the same exposure period showed no toxic signs.Skin sensitisation was observed in challenged guinea pigs that had been induced with intradermal injections of 2-ethylhexyl acrylate in concentrations of 0.5 M or 0.17 M in Freund´s complete adjuvant three times during 9 days; that had been induced with epicutaneous or intracutaneous application of 2-ethylhexyl acrylate in concentrations of 0.1% (w/v) 3 times a week for 3 weeks; or that in the Polak method had been induced with 1 mg 2-ethylhexyl acrylate in Freund´s complete adjuvant applied as injections in the footpads and the neck.Repeated application to the skin of mice, rabbits and guinea pigs caused skin irritation and subsequent degeneration of the treated areas. C3H mice were more sensitive than NMRI mice. In a lifetime study with 2-ethylhexyl acrylate applied to mice 3 times a week skin irritation was seen. The lowest dose administered was 25 ml of a 2.5% (w/w) solution of 2-ethylhexyl acrylate in acetone. Skin irritation was observed at this dose, however, after the 11th week of treatment, these lesions were reversible. For the higher doses (21% and 86.5%) further skin lesions developed.In one study 2-ethylhexyl acrylate was irritant to the rabbit eye but in another one it was non-irritating.The olfactory epithelium of the nasal mucosa was degenerated when Wistar rats inhaled 2-ethylhexyl acrylate at 225 and 750 mg/m3 6 hours a day, 5 days per week for 90 days. A reduced body weight gain, lethargy and reduced levels for albumin were also observed at these doses. Animals inhaling 75 mg/m3 for the same exposure period showed no toxic signs.An apparent increase in the frequency of chronic nephritis was seen in male C3H/HeJ mice treated three times a week for their lifetime with 20 mg 75% (v/v) 2-ethylhexyl acrylate in acetone applied to clipped dorsal skin.
