Additional information
Oral:
In an acute oral toxicity study performed according to the Acute Toxic Class method, 2000 mg/kg bw of the undiluted test item 2-Propylheptyl methacrylate was administered to two test groups of three fasted Wistar rats by gavage according to OECD guideline no. 423. The following test substance-related clinical observations were recorded (2000 mg/kg): No mortality occurred. Impaired general state in three animals. Piolerection in three animlas. The mean body weight increased withhin the normal range throughout the study period with three exceptions in both groups. One female of the first test group and two females of the scond test group showed stagnation of body weight during the second week. There were no macroscopic pathological findings at the end of the observation period. The acute oral LD50 was calculated to be LD50, oral, rat > 2000 mg/kg bw.
Inhalation:
no data
Dermal:
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 2-Propylheptyl methacrylate to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours according to OECD guideline no. 402. The application area comprised at least 10% of the total body surface area. The animals were observed for 14 days. No mortality was occurred. No signs of systemic toxicity were observed. The mean body weight of the animals increased within the normal ragne throughout the study period with two exceptions in the female group. One female lost weight and another one stagnated during the first week, but body weights were within the normal range during the second week. No macroscopic pathologic abnormalities were noted in the animals examined at eht end of the study. The acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 5000 mg/kg bw.

Justification for classification or non-classification
Based on the results, 2 -Propylheptyl methacrylate is no subject to classification and labelling according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP).
