Description of key information
Acute toxicity: oral:
In an acute oral toxicity study in female Crl:WI (Han) (SPF) rats, following the acute toxic class method in accordance with the OECD Guideline 423 and EU Method B.1 tris, the LD50 was established to be within the range of 300 - 2000 mg eq/kg. According to the OECD 423 guideline, the LD50 cut-off value was considered to be 500 mg eq/kg body weight (Latour, 2015).
Acute toxicity: inhalation:
In addition to the oral route of exposure, for substances other than gases, the information mentioned under REACH section 8.5.2 to 8.5.3 shall be provided for at least one other exposure route (REACH Regulation, column 2 adaptation of Annex VIII). For T001202, a key study is available for the dermal route of exposure. Therefore, an acute inhalation toxicity study should not be performed.
Acute toxicity: dermal:
In an acute dermal toxicity study in male and female Crl:WI (Han) (SPF) rats, following the standard acute method according to OECD Guideline 402 and EC method B.3, the LD50 was established to exceed 2000 mg eq/kg body weight (Latour, 2016).

DOSAGE PREPARATION (if unusual):
- The preparations (w/w) were kept at room temperature and were dosed within 4 hours after adding the vehicle to the test item. Homogeneity was assessed by visual inspection of the solutions and the formulations were stirred during dosing, which ensures homogeneity sufficient for these kinds of studies.
- Adjustment was made for specific gravity of the vehicle. A correction was made for the purity of the test item.
- The concentration of the test item in vehicle was varied to allow constant dosage volume in terms of ml/kg body weight.
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: the dose level was selected based on toxicity data (e.g. existing human and animal data, literature, substance data supplied by the Sponsor, analysis of structure activity relationships (SAR) and in vitro, ex-vivo and in vivo tests) of the test item (specified and approved by the Study Director in the study files). - Doses:

Mortality/viability: twice daily. Animals showing pain, distress or discomfort, which was considered not transient in nature or was likely to become more severe, were sacrificed for humane reasons based on OECD guidance document on humane endpoints (ENV/JM/MONO/ 2000/7). The time of death was recorded as precisely as possible;
Body weights: days 1 (pre-administration), 8 and 15 and at death;
Clinical signs: at periodic intervals on the day of dosing (day 1) and once daily thereafter, until day 15. The signs were graded according to fixed scales and the time of onset, degree and duration were recorded: maximum grade 4: grading slight (1) to very severe (4); maximum grade 3: grading slight (1) to severe (3); maximum grade 1: presence is scored (1).

At 2000 mg eq/kg bw, two animals were found dead and one animal was sacrificed for humane reasons, on day 1. - Clinical signs:
- At 300 mg eq/kg bw, lethargy, hunched posture, uncoordinated movements, piloerection and/or ptosis were noted for the animals on days 1 and/or 2.
At 2000 mg eq/kg bw, lethargy, flat- and hunched posture, uncoordinated movements, slow breathing, rales, shallow respiration, piloerection, watery discharge from the eyes, hypothermia and/or ptosis were noted for the animals on day 1. - Body weight:
- The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain.

- Conclusions:
- The oral LD50 value of T001202 in Wistar rats was established to be within the range of 300-2000 mg eq/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to be 500 mg eq/kg body weight.
Based on these results:
- according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011) (including all amendments), T001202 should be classified as: harmful if swallowed (Category 4);
- according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments), T001202 should be classified as Category 4 and should be labeled as H302: Harmful if swallowed.

Additional information
• Acute oral toxicity:
An acute oral toxicity study with T001202, according to the acute toxic class method (OECD guideline 423 and EU Method B.1 tris) in female Crl:WI(Han) (SPF) rats was performed (Latour, 2015). Initially, the substance was administered to three female Wistar rats at 300 mg eq/kg body weight. In a stepwise procedure two addition groups of three females were dosed at 2000 and 300 mg eq/kg body weight. The vehicle was propylene glycol. The rats received a single oral dose of test item, and were observed during 14 days following administration. At 300 mg eq/kg bw, no mortality occurred. At 2000 mg eq/kg bw, two animals were found dead and one animal was sacrificed for humane reasons, on day 1. At 300 mg eq/kg bw, lethargy, hunched posture, uncoordinated movements, piloerection and/or ptosis were noted for the animals on days 1 and/or 2. Animals dosed at 2000 mg eq/kg bw, were observed to show signs of lethargy, flat- and hunched posture, uncoordinated movements, slow breathing, rales, shallow respiration, piloerection, watery discharge from the eyes, hypothermia and/or ptosis on day 1only. The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post mortem examination of all animals.
The oral LD50 value of T001202 was established to be within the range of 300-2000 mg eq/kg body weight. According to the OECD 423 test guideline, the LD50 cut-off value was considered to be 500 mg eq/kg body weight.
This reliable guideline study is assigned as key study.
In addition, an acute oral LD50 value in rats of 226.3 (173.1 - 295.7) mg/kg body weight was established in a K4 supporting study (Schellekens, 2004). Although the LD50 value established in this study is lower than the LD50 value determined in the K1 study of Latour (2015), the result of the K4 study is not used for classification nor for risk assessment as it is not clear at which doses lower than 640 and 320 mg/kg body weight the substance was tested.
• Acute inhalation toxicity:
In addition to the oral route of exposure, for substances other than gases, the information mentioned under REACH section 8.5.2 to 8.5.3 shall be provided for at least one other exposure route (REACH Regulation, column 2 adaptation of Annex VIII). For this substance a key study is available for the dermal route of exposure. Therefore, an acute inhalation toxicity study should not be performed.
• Acute dermal Toxicity:
An acute dermal toxicity study with T001202, according to OECD guideline 402 and EU Method B.3, in male and female Crl:WI (Han) (SPF) rats was performed (Latour, 2016). The vehicle was propylene glycol and the test item formulation was applied on a clipped area on the back at a dose of 2000 mg/kg bw. After 24 hours of exposure, the test item was washed-off using tap water. The animals were observed over 14 days.
During the study no mortality occurred. Clinical signs observed were: flat posture, ptosis, piloerection and/or chromodacryorrhoea were noted for the animals on Days 1 and/or 2. White discolouration, erythema maculate, scales and/or scabs were seen in the treated skin area or left flank of the animals during the observation period. These local effects were considered not to have affected the conclusion of the study. The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity. Abnormalities of the lungs (dark red discolouration) were noted for two male animals at macroscopic post mortem examination. No abnormalities were found at macroscopic examination of the other animals. The dermal LD50 value of T001202 in Wistar rats was established to exceed 2000 mg/kg body weight.
Justification for classification or non-classification
Based on the results showing an LD50 between 300 - 2000 mg/kg eq bw and according to the criteria laid down in Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures, T001202 should be classified as acute oral toxic category 4 and should be labelled as H302: Harmful if swallowed.
No data were available to decide on the classification for the inhalation route.
Based on the dermal LD50 exceeding 2000 mg/kg bw, T001202 does not have to be classified and has no obligatory labelling requirement for acute dermal toxicity according to the criteria laid down in Regulation (EC) No 1272/2008.
