- yes
- Details on analytical verification of doses or concentrations:
- Samples of formulations were analyzed for homogeneity (highest and lowest concentration) and accuracy of preparation (all concentrations). Stability in vehicle over 5 hours at room temperature under normal laboratory light conditions was also determined (highest and lowest concentration).
The determination of Oleyl (vegetable oil) tripropylenetetramine in formulation samples was performed using LC-MS/MS.
Preparation of formulations was considered acceptable if the mean accuracy was in the range 90 – 110% of the target concentration. Homogeneity was demonstrated if the coefficient of variation was ≤ 10%. Formulations were considered stable if the relative difference between the stored and freshly taken samples was ≤ 10%. - Duration of treatment / exposure:

- - Dose selection rationale:
The dose levels were selected at 0, 5, 20 and 80 mg/kg bw/day by the Sponsor based on the available data on the very comparable substance Tallow tripropylenetetramine (C16-18, C18- unsaturated-alkyl tripropylenetetramine, CAS 1219458-11-3), for which a combined repeated dose/developmental toxicity screening study (OECD 422) was available, applying dose levels 0, 30, 100, 300 mg/kgbw/day (Notox, study 91255, 2010). This study resulted in a LOAEL of 30 mg/kg bw/day derived based on foamy macrophage infiltration in the ileum and jejunum and foamy macrophage foci found in the mesenteric lymph nodes observed at this dose level, and premature termination of 300 mg/kg bw dose-group after 10 days due to excessive mortality. The 100 mg/kg bw resulted in mortality of one male and female and lower body weights lower body weights compared to control.

Results and discussion
Results of examinations
- Clinical signs:
- effects observed, treatment-related
- Description (incidence and severity):
- Occasionally rales were noted for two male and two female animals treated at 80 mg/kg bw/day. This was not considered toxicologically relevant, considering the frequency of occurrence and minor severity of the effect.
Salivation was noted on most occasions after dosing at all dose levels with a dose related incidence. This was not considered toxicologically relevant, taking into account the nature and minor severity of the effect and its time of occurrence (i.e. after dosing). This sign was considered to be a physiological response related to taste of the test item rather than a sign of systemic toxicity. - Mortality:
- no mortality observed
- Body weight and weight changes:
- effects observed, non-treatment-related
- Description (incidence and severity):
- A trend towards a lower body weight gain was shown by females treated at 80 mg/kg bw/day during the second half of the study. This was considered not toxicologically significant since the weights were within the expected range and taking into account the nature of the effect.
- Food consumption and compound intake (if feeding study):
- effects observed, non-treatment-related
- Description (incidence and severity):
- A trend towards a lower food consumption before and after correction for body weight for females treated at 80 mg/kg bw/day was shown. This was considered not toxicologically significant, taking into account the nature of the effect and since the values were within the expected range.
- Food efficiency:
- not examined
- Water consumption and compound intake (if drinking water study):
- no effects observed
- Ophthalmological findings:
- not examined
- Haematological findings:
- effects observed, treatment-related
- Description (incidence and severity):
- Lower red blood cells counts, haemoglobin and haematocrit in males and higher activated partial thromboplastin time (APTT) in females at 80 mg/kg bw/day, distinguished treated from control animals but were slight in nature and in the absence of corroborative findings it was considered that these changes were not toxicologically relevant.
- Clinical biochemistry findings:
- effects observed, treatment-related
- Description (incidence and severity):
- Alanine aminotransferase activity (ALAT) was increased in both sexes at 80 mg/kg bw/day compared to control animals. In addition, lower total protein, lower albumin and slightly increased total bilirubin (not statistically significant) was observed in males at 80 mg/kg bw/day compared to controls.
- Urinalysis findings:
- not examined
- Behaviour (functional findings):
- no effects observed
- Immunological findings:
- not examined
- Organ weight findings including organ / body weight ratios:
- no effects observed
- Gross pathological findings:
- no effects observed
- Neuropathological findings:
- not examined
- Histopathological findings: non-neoplastic:
- effects observed, treatment-related
- Description (incidence and severity):
- Test item-related microscopic findings were noted in the jejunum, ileum and mesenteric lymph nodes.
Vacuolated macrophages were observed in lamina propria in 1/5 males (slight) and 1/5 females (minimal) of the jejunum in the 80 mg/kg bw/day group. In the ileum, foamy vacuolated macrophages in lamina propria were observed in 4/5 males and 5/5 females at 20 mg/kg bw/day and in 3/5 males and 2/5 females (minimal) and in 1/5 males and 3/5 females (slight) at 80 mg/kg bw/day.
In the mesenteric lymph node an increased incidence and severity of macrophage foci (in the (para)cortex) was observed in animals of the 20 and 80 mg/kg bw /day group. Minimal macrophage foci (in the (para)cortex) were observed in 1/5, 2/5 and 1/5 animals of both sexes in the 5, 20 and 80 mg/kg bw/day treatment groups, respectively. Slight macrophage foci (in the (para)cortex) were found te be present in 1/5 males and 2/5 females at 20 mg/kg bw/day and in 4/5 animals of both sexes at 80 mg/kg bw/day. In two females of the 20 mg/kg bw/day group and in all animals of the 80 mg/kg bw/day group the macrophages involved often had foamy vacuolated cytoplasm. In addition, minimal sinus histiocytosis was observed in 1/5 males and 2/5 females, slight sinus histiocytosis in 3/5 males and 3/5 females and moderate sinus histiocytosis in 1/5 males of the 80 mg/kg bw/day group. - Histopathological findings: neoplastic:

Analytical verification of doses
In total, 20 samples were included in this study. Samples for Group 1 and Group 3 were taken in duplicate from the middle position of the container and samples for treatment Groups 2 and 4 were taken in duplicate from the top, middle and bottom position.
In the Group 1 formulation, no test item was detected. The mean accuracies of the formulations of Groups 2, 3 and 4 were 98.5%, 96.4% and 101.6%, respectively and in agreement with the target concentrations (i.e. mean accuracies between 90% and 110%).
The coefficient of variation for the formulations of Group 2 and Group 4 were 1.1% and 1.0%, respectively and were considered homogeneous (i.e. coefficient of variation ≤ 10%). Analysis of Group 2 and Group 4 formulations after storage yielded a relative difference of -2.4% and -1.0%, respectively. Based on this, the formulations were found to be stable during storage at room temperature under normal laboratory light conditions for at least 5 hours.
Applicant's summary and conclusion
- Conclusions:
- In a 28-day oral repeated dose toxicity study with rats according to OECD/EC guidelines and in compliance with GLP principles, the NOAEL for Oleyl (vegetable oil) tripropylenetetramine was determined to be 80 mg/kg bw/day based on the absence of adverse effects at the highest dose level in this study. However, based on observed foamy macrophages in jejunum, ileum and mesenteric lymph nodes, although not considered adverse, the NOAEL is set on 20 mg/kg bw/day.
- Executive summary:
A repeated dose 28-day oral toxicity study with Oleyl (vegetable oil) tripropylenetetramine by daily gavage in the rat was performed according to OCED guideline 407 and in compliance with GLP.
The dose levels were selected at 0, 5, 20 and 80 mg/kg by the Sponsor based on the available data on the very comparable substance Tallow tripropylenetetramine (C16-18, C18-unsaturated-alkyl tripropylenetetramine, CAS 1219458-11-3), for which a combined repeated dose/developmental toxicity screening study (OECD 422) was available, applying dose levels 0, 30, 100, 300 mg/kgbw/day (Notox, study 91255, 2010). This study resulted to a LOAEL of 30 mg/kg bw/day was derived based on foamy macrophage infiltration in the ileum and jejunum and foamy macrophage foci found in the mesenteric lymph nodes observed at this dose level, and premature termination of 300 mg/kg bw dose-group after 10 days due to excessive mortality. The 100 mg/kg bw resulted to mortality of one male and female and lower body weights lower body weights compared to control.
Study outline
The test item, formulated in propylene glycol, was administered daily for 28 days by oral gavage to SPF-bred Wistar rats. One control group and three treated groups were tested, each consisting of 5 males and 5 females.
Evaluated parameters
Chemical analyses of formulations were conducted once during the study to assess accuracy, homogeneity and stability over 5 hours. The following parameters were evaluated: clinical signs daily; functional observation tests in Week 4; body weight and food consumption weekly; clinical pathology and macroscopy at termination; organ weights and histopathology on a selection of tissues.
Results
Formulation analyses confirmed that formulations of test item in propylene glycol were prepared accurately and homogenously, and were stable over at least 5 hours.
No toxicologically significant changes were noted in the following parameters investigated in this study (i.e. clinical signs, functional observations, body weight, food consumption, clinical laboratory investigations, macroscopic examination and organ weights).
Histopathological examination showed no adverse effects as a result of treatment across all doses, and the test item was well tolerated. Despite this, treatment at dose levels of 20 and 80 mg/kg resulted in accumulation of most probably the test item or derivatives within cells of the phagocytic system of the small intestines and draining mesenteric lymph node. However, since this accumulation was found in the absence of clear signs of degeneration, necrosis or accompanying inflammatory changes, it can be concluded that the effects observed were not adverse and only represent adaptive changes.
Conclusion
From the results presented in this report a definitive No Observed Adverse Effect Level (NOAEL) for Oleyl (vegetable oil) tripropylenetetramine of 80 mg/kg was established. However, based on observed foamy macrophages in jejunum, ileum and mesenteric lymph nodes, although not considered adverse, the NOAEL is set on 20 mg/kg bw/day.
