Description of key information

Acute toxicity: Oral

In two separate acute oral toxicity study in female rats, following the acute toxic class method in accordance with the OECD Guideline 423, the LD50 was established to be greater than 2000 mg/kg (Latour 2017 and Herlich 2012).

 

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 T003422, 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/kg body weight (Latour, 2016).

KG, Rosenberg, Germany) and paper as cageenrichment (Enviro-dri, Wm. Lillico & Son (Wonham Mill Ltd), Surrey, United Kingdom)
- Diet (e.g. ad libitum): Free access to pelleted rodent diet

- Air changes (per hr): at least 10 air changes/hour
- Photoperiod (hrs dark / hrs light): 12-hour light/12- hour dark cycle

Route of administration:
oral: gavage
Vehicle:
propylene glycol
Details on oral exposure:
VEHICLE
- Concentration in vehicle: 200 mg/mL
- Amount of vehicle (if gavage): 2000 mg/kg (10 mL/kg) body weight
- Justification for choice of vehicle: The vehicle was selected based on trial preparations performed at Charles River Den Bosch and on test item data supplied by the Sponsor. The vehicle was chosen from (in order of preference): water (Elix) (test item did not dissolve), 1% aq. carboxymethyl cellulose (test item did not dissolve), propylene glycol (spec.gravity 1.036) (clear solution), polyethylene glycol 400 (spec. gravity 1.125) and corn oil (spec. gravity 0.92).
There was no information available regarding the solubility in vehicle.

MAXIMUM DOSE VOLUME APPLIED: 10 ml/kg

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 sufficiently for these kinds of studies. Adjustment was made for specific gravity of the vehicle. No correction was made for purity of the test item as the correction factor is 1.

CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: The toxicity of the test item was assessed by stepwise treatment of groups of 3 females. The first group was treated at a dose level of 2000 mg/kg.
The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration and severity of the signs of toxicity were taken into account for determination of the
time interval between the dose groups.
Doses:
2000 mg/kg (10 mL/kg) body weight
No. of animals per sex per dose:
3 females per dose
Control animals:
no
Details on study design:
- Duration of observation period following administration: 15 days
- Frequency of observations and weighing:
Mortality/Viability: Twice daily.
Body weights: Days 1 (pre-administration), 8 and 15.
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).
- Necropsy of survivors performed: yes; At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide procedure and subjected to necropsy. Descriptions of all internal macroscopic abnormalities were recorded.
Statistics:
No statistical analysis was performed.

Mortality:
No mortality occurred.
Clinical signs:
other: Lethargy, uncoordinated movements, piloerection and/or hunched posture were noted for all animals on Day 1. Additionally, hunched posture was noted for two animals on Days 2 and 3.
Body weight:
other body weight observations
Remarks:
The mean 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.
Gross pathology:
No abnormalities were found at macroscopic post mortem examination of all animals.
Interpretation of results:
GHS criteria not met
Conclusions:
The oral LD50 value of T003422 in Wistar rats was established to exceed 2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.
Based on these results, T003422 does not have to be classified and has no obligatory labelling requirement for acute oral toxicity according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2015) (including all amendments) and Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments).

Additional information

Acute Oral Toxicity:

An acute oral toxicity study with T003422 according to the acute toxic class method in female rats (OECD guideline 423) was performed (Latour 2017).

The test substance was administered by oral gavage to two subsequent groups of three female Wistar rats at 2000 mg/kg body weight. Animals were subjected to daily observations and weekly determination of body weight.

Macroscopic examination was performed after terminal sacrifice (Day 15). No mortality occurred.

Lethargy, uncoordinated movements, piloerection and/or hunched posture were noted for all animals on Day 1. Additionally, hunched posture was noted for two animals on Days 2 and 3.

The mean body weight gain shown by the animals over the study period was considered to be normal.

No abnormalities were found at macroscopic post mortem examination of all animals.

The oral LD50 value of T003422 in Wistar rats was established to exceed 2000 mg/kg body weight.

According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 5000 mg/kg body weight.

A second study (Herlich 2012) was also performed according the OECD 423 test guideline and established an LD50 greater than 2000 mg/kg bw.

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 T003422, 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 deral toxicity study with T003422 according to OECD guideline 402 and EU Method B.3 in male and female Crl:WI (Han) (SPF) rats was performed (Latour, 2016).

The test substance was administered to five Wistar rats of each sex by a single dermal application at 2000 mg/kg body weight for 24 hours. Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15).

No mortality occurred.

Chromodacryorrhoea (snout) was noted for four males and two females on Days 1 and/or 2.

The mean body weight gain during the observation period was within the range expected for rats used in this type of study.

No abnormalities were found at macroscopic post mortem examination of the animals.

The dermal LD50 value of T003422 in Wistar rats was established to exceed 2000 mg/kg body weight.

Justification for classification or non-classification

Acute Oral Classification:

Based on these results, T003422 does not have to be classified under EU CLP.

 

Acute Inhalation Classification:

No data were available to decide on the classification for the inhalation route.

 

Acute Dermal Classification:

Based on these results, T003422 does not have to be classified under EU CLP.
