The inhalation hazard test demonstrates the toxicity of an atmosphere saturated with vapors of the volatile components of a test substance at the temperature chosen for vapor generation (usually 20°C). Groups of rats were sequentially exposed to the vapors, generated by bubbling 200 l/h air through a substance column of about 5 cm above a fritted disc in a glass cylinder for different time periods.
No analytical determination of the atmosphere concentrations was performed. The nominal concentration usually can be calculated as quotient of the amount of the test substance weight loss during exposure. Group-wise documentation of clinical signs was performed over the 14 day study period. Body weight of groups was determined before the start of the study and at the end of the observation period in surviving animals. - GLP compliance:

Young adult laboratory rats, 6 per sex, were exposed sequentially to the vapors generated by bubbling 200 L/h air through a substance column of about 5 cm above a fritted glass disc in a glass cylinder for 7 hours. No analytical determination of the atmosphere concentrations was performed. The nominal concentration was calculated as 0.000545 mg/l based on the vapor pressure. Group-wise documentation of clinical signs was performed over a 14 day study period. All animals survided inhalative exposure and showed no gross pathology findings. Clinical symptoms soley included wiping of the snout throughout expsoure.
Based on the study findings no acute inhalation toxicity can be concluded for animals expsosed to a saturated vapor of the test item.

- Executive summary:
Acute dermal toxicity was investigated with 10 albino rabbits (five/sex) treated with a single dose of 2000 mg/kg similar to OECD protocol of guideline 402 (GLP not specified, reliability 2). Single occlusive dosing at a dose volume of 1.9 ml/kg was performed on abraded skin for 24 hours. Under this study conditions no mortality was observed during the observation period of 14 days. Four males and three females exhibited slight weight gains, whereas one male and one female rabbit exhibited no net change in theig bodyweight. One female animal exhibited a weight loss, however, this animal was noted to have a possible broken leg or lower lack injury during the second week of the study. Well defined to severe erythema accompanied by very slight or moderate edema were observed in males after 24 hours. Females exhibited very slight or well-defined erythema accompanied by severe edema. No abnormalities of clinical signs were noted during the four hours after dosing. Three males exhibited fecal staining at 24 hours and one female exhibited this sign at 24 hours and on Day 2. One female exhibited decreased food consumption at 24 hours. One female exhibited clear nasal discharge on a single occasion and clear ocrilar discharge on several occasions. Another female was noted to have an apparent broken leg or lower back on Day 9 and exhibited soft stool, fecal staining and/or urinary staining, decreased food consumption, decreased activity and/or prostration from Day 9 through termination. Six of the tested ten animals had gross pathology findings which included: 5/10 animals with slightly irregular, slightly diminished or purplish spleen, 2/10 animals mottled pale liver (20%-40%), 2/10 animals with pale kidneys, 1/10 animals with slight fecal staining, 1/10 animals with empty stomach, 1/10 animals with broken leg.
Due to the abscence of mortality under the tested conditions of this study no LD50 value was derived.

Additional information
There are valid data available for the assessment of the acute oral, dermal and inhalative toxicity of the test substance.
Oral
In a standard acute test, according to OECD guideline 423 and in compliance with GLP, six female Wistar rats were treated with 2000 mg/kg bw tripropylene glycol diacrylate under standardized conditions (2004). The animals were observed for 14 d, necropsy was performed even with the survivors. No deaths occurred, the LD50 is > 2000 mg/kg bw for female rats. No clinical signs of toxicity were reported. The mean body weights of the administration groups increased throughout the study period and no macroscopic pathologic abnormalities were noted in the animals examined at termination of the study.
Other reliable study findings are available and support the key finding.
In an oral toxicity study, 5 male and 5 female Sprague-Dawley rats were administered 5000 mg/kg bw of the test material under standardized conditions (1982, realibility 2). The animals were observed for 14 d, necropsy was performed even with the survivors. One male animal died on day 2 and one female animal died on day 1, in total 2/10 animals died, the LD50 is >5000 mg/kg bw for female rats. Dyspnoe, apathy, staggering, scrubby fur, salivation and a generally bad general condition were observed. The mean body weight increased within the normal range during the study period. At gross necropsy an acute dilatation of the prechambers of the heart, acute congestive hyperanemia, as well as vascula injections in the stomach/intestine were seen in the animals that died during the study and the intestine was atonic. In the sacrificed animals the gastroesophageal vestibule was thickened in the stomach and a sporadic agglutination of the gastroesophageal vestibule with the peritoneum was seen.
In two further studies, both similar to OECD 401, rats were administered 5000, 6400, 8000 and 10000 mg/kg bw and 3500, 5000, 7000, 10000 and 14200 mg/kg bw, respectively under standardized conditions (1980, 1984, both reliability 2). In both studies the LD50 was 6800 mg/kg bw for male and female rats.
Inhalation
The acute inhalation toxicity was investigated in an Inhalation Risk test with rats (1982, reliability 2). The test was performed in principle as described in OECD test guideline 403 (GLP not specified) with an atmosphere saturated with vapors of the volatile components of a test substance at 20 °C. Young adult laboratory rats, 6 per sex, were exposed sequentially to the vapors generated by bubbling 200 L/h air through a substance column of about 5 cm above a fritted glass disc in a glass cylinder for 7 hours. No analytical determination of the atmosphere concentrations was performed. The nominal concentration was calculated as 0.00054 mg/l based on the vapor pressure. Group-wise documentation of clinical signs was performed over a 14 day study period. All animals survided inhalative exposure and showed no gross pathology findings. Clinical symptoms soley included wiping of the snout throughout exposure. The gross necropsy of all animals was inconspicuous.
Based on the study findings no acute inhalation toxicity can be concluded for animals exposed to a saturated vapor of the test item.
Dermals
Acute dermal toxicity was investigated with 10 albino rabbits (five/sex) treated with a single dose of 2000 mg/kg similar to OECD protocol of guideline 402 (1980, GLP not specified, reliability 2). Single occlusive dosing at a dose volume of 1.9 ml/kg was performed on abraded skin for 24 hours. Under this study conditions no mortality was observed during the observation period of 14 days. Four males and three females exhibited slight weight gains, whereas one male and one female rabbit exhibited no net change in their bodyweight. One female animal exhibited a weight loss, however, this animal was noted to have a possible broken leg or lower lack injury during the second week of the study. Well defined to severe erythema accompanied by very slight or moderate edema were observed in males after 24 hours. Females exhibited very slight or well-defined erythema accompanied by severe edema. No abnormalities of clinical signs were noted during the four hours after dosing. Three males exhibited fecal staining at 24 hours and one female exhibited this sign at 24 hours and on Day 2. One female exhibited decreased food consumption at 24 hours. One female exhibited clear nasal discharge on a single occasion and clear ocular discharge on several occasions. Another female was noted to have an apparent broken leg or lower back on Day 9 and exhibited soft stool, fecal staining and/or urinary staining, decreased food consumption, decreased activity and/or prostration from Day 9 through termination. Six of the tested ten animals had gross pathology findings which included: 5/10 animals with slightly irregular, slightly diminished or purplish spleen, 2/10 animals mottled pale liver (20%-40%), 2/10 animals with pale kidneys, 1/10 animals with slight fecal staining, 1/10 animals with empty stomach, 1/10 animals with broken leg.
Due to the absence of mortality under the tested conditions of this study no LD50 value was derived.
Justification for classification or non-classification
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. No mortality occurred at the limit dose of 2000 mg/kg bw via the oral and dermal route. As a result, the substance is not considered to be classified for acute oral or dermal toxicity under Regulation (EC) No. 1272/2008, as amended for the thirteenth time in Regulation (EC) No. 2018/1480.
Since an inhalation hazard tests with rats exposed to a saturated vapor atmosphere of the test item for 7 h revealed no mortality and only transient clinical signs, there is no indication given to classify the substance according to EU or GHS requirements for its acute inhalation toxicity. It is stressed, that due to the high reactivity of the substance, aerosols should not be inhaled.
