- Details on study design:
- This test (also called inhalation risk test) was performed in principle as described in OECD Guideline 403. It demonstrates the toxicity of an atmosphere saturated with vapors of the volatile components of a test substance at the temperature chosen for vapor generation (here 20 °C). Groups of 3 rats per sex were exposed 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 8 hours. For confirmation of the results, the experiment was repeated once. No analytical determination of the atmosphere concentrations was performed.
The nominal concentration was calculated as quotient of the amount of test substance weight loss during the exposure and the amount of air used during the exposure.
Group-wise documentation of clinical signs was performed over the 7-day study period. Body weight of groups was determined before the start of
the study and at the end of the observation period in the surviving animals. The clinical signs and findings were reported in summarized form. Upon completion of the study, all animals were sacrificed and submitted to gross-pathological examination. The study allows for an estimate of the length of time required to cause severe toxic effects resulting from exposure to an atmosphere saturated with volatile components of the test substance. - Sex:

- Executive summary:
In an acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 5000 mg/kg bw of the undiluted test item to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours. The application area comprised at least 10 % of the total body surface area. The animals were observed for 14 days.
The following test item-related effects were recorded during the course of the study:
- No mortality occured
- No signs of systemic toxicity
- Very slight to severe erythema (grade 1 to 4)
- Very slight to moderate edema (grade 1 to 3)
- Incrustrations
- Severe scaling
- Additionally, all local signs were noted beyond the application site.
- The mean body weight of the male animals increased within the normal range throughout the study period. The mean body weights of the female animals did not adequately increase during the first post-exposure observation week, probably due to the bandage procedure, but increased during the second week...
- No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study.
Accordingly, the acute dermal median lethal dose (LD50) was determined to be > 5000 mg/kg bw in rats.

Additional information
Acute oral toxicity:
In the key study, a read across substance (mixture of laurylacrylate (CAS No.: 2156-97-0) and tetradecylacrylate (CAS No.: 21643-42-5)) was tested according to an internal BASF method which in principle is comparable to the methods described in OECD Guideline 401. The doses were 0.2, 1.6, 3.2, and 6.4 mL/kg bw (corresponding to 174, 1392, 2784, and 5568 mg/kg bw). Several groups of 5 rats per sex and dose were treated simultaneously by gavage with preparations of the test substance in aqueous emulsion with traganth. Group-wise documentation of clinical signs was performed over the 7-day study period. Body weight was determined before the start of the study only, as it was needed for determination of dose. The clinical signs and findings were reported in summary form. Upon completion of the study, all animals were sacrificed and submitted to gross-pathological examination. No mortality was revealed. The animals of the highest dose group showed slight apathy and piloerection during the first 24 hours. Among the animals of the next two dose groups (2784 and 1392 mg/kg bw) slight apathy was also observed. No other clinical signs were recorded. All symptoms disappeared within the first day of the experiment. No macroscopic pathologic abnormalities were noted in the surviving animals examined at the end of the observation period. The read across substances Lorolacrylat 1214 revealed an oral LD50 > 5570 mg/kg bw.
In the supporting study, a read across substance (mixture of acrylic esters of saturated unbranched alcohols with C10-C16 carbon chain length) was tested according to an internal BASF method which in princile is comparable to the methods described in OECD Guideline 401. The doses were 0, 0.2, 1.6, 6.4, and 10.0 mL/kg bw (corresponding to approx. 0, 174, 1392, 5568, and 8700 mg/kg bw). Several groups of 5 rats per sex and dose were treated simultaneously by gavage with preparations of the test substance in aqueous emulsion with traganth. Group-wise documentation of clinical signs was performed over the 7-day study period. Body weight was determined before the start of the study only, as it was needed for determination of dose. The clinical signs and findings were reported in summary form. Upon completion of the study, all animals were sacrificed and submitted to gross-pathological examination. No mortality was revealed. No clinical signs or symptoms were observed during the study. No macroscopic pathologic abnormalities were noted in the surviving animals examined at the end of the observation period.

In supporting study, a read substance (mixture of acrylic esters of saturated unbranched alcohols with C10-C16 carbon chain length) was tested performed in principle as described in OECD Guideline 403. It demonstrates the toxicity of an atmosphere saturated with vapors of the volatile components of a test substance at the temperature chosen for vapor generation (here 23 °C). Groups of 3 rats per sex were exposed to the vapors, generated by bubbling 100 L/h air through a substance column of about 5 cm above a fritted glass disc in a glass cylinder for 8 hours. For confirmation of the results, the experiment was repeated once. No analytical determination of the atmosphere concentrations was performed. The nominal concentration could not be calculated in this test, since several times during the 8-hr exposure period etingal A and silicon oil had been added to the test substance in order to prevent frothing. Group-wise documentation of clinical signs was performed over the 7-day study period. Body weight of groups was determined before the start of the study and at the end of the observation period in the surviving animals. The clinical signs and findings were reported in summarized form.

No macroscopic pathologic abnormalities were noted in the surviving animals examined at the end of the observation period.
Acute dermal toxicity:
In an acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 5000 mg/kg bw of the undiluted read across substance (CAS no. 84238-60-8) to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours. The application area comprised at least 10% of the total body surface area. The animals were observed for 14 days. No mortality occurred. No signs of systemic toxicity was observed ( Very slight to severe erythema (grade 1 to 4), Very slight to moderate edema (grade 1 to 3)). No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study. Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 5000 mg/kg bw.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitabke for classification purposes under Regulation 1272/2008. No mortality occured at the limit dose of 5000 mg/kg bw in an acute oral and an acute dermal toxicity study. Additionally, no mortality occured in an acute inhalation toxicity study. As a result the substance is not considered to be classified for acute oral, dermal or inhalative toxicity under Regulation (EC) No. 1272/2008, as amended for the tenth time in Regulation (EC) No. 2017/776.
