Endpoint summary
Administrative data
Description of key information
Acute toxicity:Oral
The acute oral median lethal dose (LD50) of test chemical in male/female sprague-dawley rat was determined to be 8440-9710 mg/kg of body weight. LD50 value indicates that the test chemical does not exhibits acute toxicity by the oral route.
Acute Toxicity:Inhalation
The particle size distribution of the test substance was found to vary in the size of 53-500 µm, so the potential for the generation of inhalable forms is low.Moreover the normal conditions of use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be unlikely to occur, and therefore acute toxicity by inhalation route was considered to be waived.

Clinical Observations and General Appearance:
Animals were observed for clinical signs, mortality, until sacrifice.
Onset, duration and severity of any sign were recorded. The clinical signs and mortality observations were conducted at 10, 30, 60 minutes, 2, 4 and 6 hours on the day of dosing and once daily thereafter for 14 day. Daily observation was done as far as possible at the same time.
The observations were included general clinical signs, observations of eyes, mucous membranes, respiratory, circulatory system and behavior pattern.
Evaluation of Dermal Reaction:
Dermal reaction was observed daily for study period of 14 days.
Body weights:
Individual animal body weights were recorded pre-test (prior to administration of the test item), day 7 and at termination on day 14.
Gross Pathology:
Necropsy was performed on animals surviving at the end of the study. Macroscopic examination of all the orifices, cavities and tissues were made and the findings were recorded. All animals surviving the study period were sacrificed by the carbon dioxide asphyxiation technique (day 15).
Histopathology:
No gross abnormalities were observed in animals sacrificed terminally hence, no histopathology was performed.

- Conclusions:
- According to CLP regulation, the test chemical cannot be classified for acute dermal toxicity, as the LD50 value is >2000 mg/kg bw.
- Executive summary:
In different studies, the given test chemical has been investigated for acute dermal toxicity to a greater or lesser extent. Often are the studies based on in-vivo experiments in rodents, i.e. most commonly in rats for test chemical. The studies are summarized as below –
The study now reported was designed and conducted to determine the acute dermal toxicity profile of test chemical in Sprague Dawley rats.
The test item was applied to shorn skin of 5 male and 5 female animals at 2000 mg/kg body weight. Administration of the test item at 2000 mg/kg did not result in any skin reaction at the site of application during the study period of 14 days. Administration of the test item did not result in any signs of toxicity and mortality during the study period of 14 days.
Animals exhibited normal body weight gain through the study period of 14 days.
Gross pathological examination did not reveal any abnormalities attributable to the treatment.
It was concluded that the acute dermal median lethal dose (LD50) of test chemical, when administered to male and female Sprague Dawley rats was found to be greater than 2000 mg/kg body weight. Thus, according to CLP criteria for acute toxicity rating for the chemicals, it infers that test chemical does not classify as an acute dermal toxicant.
The above study is supported with another study conducted on rabbit The test chemical was applied onto the skin of rabbits.
The acute dermal LD50 for test chemical was determined to be greater than 5000mg/kg.
Based on value the chemical was not classified as per CLP regulations.
The above study further supported with another study conducted on rabbits, The animals were treated with test chemical. No mortality was observed in treated rabbits. Therefore, LD50 was considered to be > 5000 mg/kg bw when rabbits were treated with test chemical dermally.
Thus, based on the above summarised studies on test chemical, it can be concluded that LD50 value is >2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, the given test chemical cannot be classified for acute dermal toxicity.

Additional information
Acute toxicity:Oral Route
The acute oral toxicity of test chemical was performed in Sprague-Dawley rats . For this purpose, the product was administered once by gavage as a 50% solution in aqua dest . in doses of 5620, 6810, 8250 and 10000 mg/kg .
The median lethal dose (LD 50) after 14 days was observed to be8980 (8440 - 9710) mg/kgin male and female rats.Inmale animals LD50 value was observed to be 9140 (8350 - 10510) mg/kgwhereas infemale animals ,8820 (7960 - 10090) mg/kg.
From the above study it is concluded that test chemicaldoes not exhibits acute toxicity by the oral route.
The study is supported by an acute oral toxicity of test chemical was performed in NMRI mice . For this purpose, the product was administered once by gavage as a 50% solution in distilled water in doses of 10000 mg/kg once by gavage.
No death was observed at a dose of 10000 mg/kg bw in male and female mice,hence LD50 value was considered to be >10000 mg/kg bw
From the above studies it is concluded that test chemical does not exhibits acute toxicity by the oral route.
Acute Toxicity:Inhalation
The particle size distribution of the test substance was found to vary in the size of 53-500 µm, so the potential for the generation of inhalable forms is low.Moreover the normal conditions of use of this substance will not result in aerosols, particles or droplets of an inhalable size, so exposure to humans via the inhalatory route will be unlikely to occur, and therefore acute toxicity by inhalation route was considered to be waived.
Acute toxicity:Dermal
In different studies, the given test chemical has been investigated for acute dermal toxicity to a greater or lesser extent. Often are the studies based on in-vivo experiments in rodents, i.e. most commonly in rats for structurally similar read across chemicals.The studies are summarized as below:

Justification for classification or non-classification
Based upon the studies reviewed it can be concluded that, the test chemicalis not expected to show acute toxicity effect by the oral, inhalation and dermal route and thus will not be considered for further classification.
