Interpretation of results:
practically nontoxic
Remarks:
Migrated information
Conclusions:
Under the conditions of this study the median lethal dose of the test substance after oral application was found to be greater than 2000 mg/kg body weight for the male and female animals.
Executive summary:

The study was performed to assess the acute toxicity following oral administration of the test substance, applied as a suspension in olive oil DAB 10, in Wistar rats. The study procedure was based on the EEC gudeline and modified according to the acute toxic class method. To each group of six fasted animals (three males and three females) a single oral dose of the test material preparation in olive oil DAB 10 at dose levels of 200 and 2000 mg/kg body weight was given.

Signs of toxicity noted in male animals of the 200 and 2000 mg/kg dose groups comprised impaired or poor general state, dyspnoea, apathy and staggering. These symptoms are considered to be unspecific toxicity symptoms. The animals appeared normal within 2 days after application. The female rats of both dose groups did not show any signs of toxicity. The expected body weight gain was oberved in the course of the study. No mortality occured. No abnormalities were noted at necropsy of animals sacrificed at the end of the study.

Conclusion: Under the conditions of this study the median lethal dose of the test substance after oral application was found to be greater than 2000 mg/kg body weight for the male and female animals.

Interpretation of results:

Remarks:
Migrated information
Conclusions:
Under the conditions of this study the median lethal dose (LD50) of Polyglycerintribehenat after dermal application was found to be greater than 2000 mg/kg bw in male and female rats.
Executive summary:

The study was performed according to OECD guideline 402 in compliance with GLP.

In this acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of Polyglycerintribehenat (as paste in olive oil Ph.Eur.) 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 or skin effects were observed in the animals. The mean body weight of the male animals increased within the normal range throughout the study period. The mean body weight of the female animals stagnated during the first post-exposure 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.

 

Conclusion: Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 2000 mg/kg bw.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed

Additional information

Acute oral toxicity

The key study (BASF AG, 1998) was performed to assess the acute toxicity following oral administration of the test substance, applied as a suspension in olive oil DAB 10, in Wistar rats. The study procedure was based on the EEC gudeline and modified according to the acute toxic class method. To each group of six fasted animals (three males and three females) a single oral dose of the test material preparation in olive oil DAB 10 at dose levels of 200 and 2000 mg/kg body weight was given.

Signs of toxicity noted in male animals of the 200 and 2000 mg/kg dose groups comprised impaired or poor general state, dyspnoea, apathy and staggering. These symptoms are considered to be unspecific toxicity symptoms. The animals appeared normal within 2 days after application. The female rats of both dose groups did not show any signs of toxicity. The expected body weight gain was oberved in the course of the study. No mortality occured. No abnormalities were noted at necropsy of animals sacrificed at the end of the study.

Under the conditions of this study the median lethal dose of the test substance after oral application was found to be greater than 2000 mg/kg body weight for the male and female animals.

Acute dermal toxicity

The key study was performed according to OECD guideline 402 in compliance with GLP (BASF SE, 2011). In this acute dermal toxicity study (Limit Test), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of Polyglycerintribehenat (as paste in olive oil Ph.Eur.) 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 or skin effects were observed in the animals. The mean body weight of the male animals increased within the normal range throughout the study period. The mean body weight of the female animals stagnated during the first post-exposure 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.

Accordingly, the acute dermal median lethal dose (LD50) was determined to be LD50, dermal, rat > 2000 mg/kg bw.


Justification for selection of acute toxicity – oral endpoint
only available reliable study

Justification for selection of acute toxicity – dermal endpoint
only available reliable study

Justification for classification or non-classification

Based on the results of the available acute toxicity studies the test item does not need to be subjected to classification and labelling according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP/GHS).
