Mortality:

In the 2000 mg/kg test group two animals were found dead on study day 8 or 9 after administration. Due to the high weight loss, the remaining animal of this test group was sacrificed in a moribund state on study day 9. No mortality occurred in the 300 mg/kg test groups.

Clinical signs:

other: In the animals of the 2000 mg/kg bw test group, impaired general state, dyspnoea, piloerection, reduced feces, and exsiccosis were noted from study day 2 or 3 onwards. In the animal that was sacrificed moribund, poor general state and cachexia were noted

Gross pathology:

In the animals that died Peyer’s plaques in the small intestine (one animal) and swollen lymph nodes in region of the small intestine and red discoloration of the small intestine in the second animal. In the animal that was sacrificed moribund swollen lymph nodes in region of the small intestine and red discoloration of the small intestine were also observed.

There were no macroscopic pathological findings in the surviving animals sacrificed at the end of the observation period (300 mg/kg, 6 females).

Additional information

In an acute oral toxicity study according to OECD423 and GLP (BASF SE 2012), fasted female Wistar rats were given a single oral dose of 2000mg/kg undiluted Reaction products of Fatty acids, tall-oil, compds. with oleylamine and Fatty acids, C18-unsatd., trimers, compds. with oleylamine or 300mg/kg of the test substance in olive oil by gavage. The animals were observerd for 14 days and necropsy was performed. Of the three high dose females, two animals died on days 7 and 8, the surviving animal was sacrificed moribund on day 9. Impaired general state, dyspnoea, piloerection, exsiccosis, reduced feces, and weight loss were observed in all animals of this group. Gross pathology revealed swollen lymph nodes and peyer's plaques in region of the small intestine and red discoloration of the small intestine. No mortality was observed in the two independent experiments using 300mg/kg. In the first experiment, impaired general state, dyspnoea, and piloerection were observed, while no clinical signs occured in the second experiment. The body weight increased in the expected range. Thus the oral LD50 value for this substance is greater than 300mg/kg b.w., but below 2000mg/kg b.w.

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 undiluted Reaction products of Fatty acids, tall-oil, compds. with oleylamine and Fatty acids, C18-unsatd., trimers, compds. with oleylamine to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours (BASF SE 2013). No mortality and no systemic toxicity was observed during the for 14 days observation period. The mean body weight of the male animals increased within the normal range throughout the study period. Mean body weight of the female animals stagnated during the first postexposure observation week, probably due to the bandage procedure, but increased during the second week within the normal range. No macroscopic pathologic abnormalities were noted in the animals examined at the end of the study. The following test item-related local effects were recorded during the course of the study:

o Very slight to moderate erythema (grade 1 to 3)

o Very slight to moderate edema (grade 1 to 3)

o Scaling and severe scaling

o Incrustations

Accordingly, the acute dermal median lethal dose (LD50) was determined to be > 5000 mg/kg b.w. in rats.

In accordance with column 2 of REACH Annex VIII, no acute inhalation toxicity study was conducted as two other routes are provided.

Justification for classification or non-classification

Based on the results of the available studies, the reaction mass of fatty acids, tall-oil, compds. with oleylamine and fatty acids, C18-unsatd., trimers, compds. with oleylamine classified as harmful after oral exposure, R22 according to 67/548/EEC and cat. 4 according to CLP/EU-GHS requirements. The test substance does not have to be classified for ist toxic potential after dermal exposure.
