Endpoint summary
Administrative data
Description of key information
In the rat acute oral toxicity study, a single 300 mg/kg dose proved lethal, and necropsy revealed damage to the stomach mucosa. No deaths followed dosing at 50 mg/kg.
Key value for chemical safety assessment
Acute toxicity: via oral route

- EPA OPPTS 870.1100 (Acute Oral Toxicity)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Test type:
- acute toxic class method
- Limit test:
- no
- Species:
- rat
- Strain:
- Wistar
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Strain: Wistar strain Crl:WI(Han)
- Source: Charles River Deutschland, Sulzfeld, Germany
- Age at study initiation: approx. 9-12 weeks old
- Weight at study initiation: 166-189 g
- Fasting period before study: Food was withheld overnight (for a maximum of 20 hours) prior to dosing until 3-4 hours after administration of the test substance.
- Housing: Group housing of 3 animals per cage in labelled Macrolon cages
- Diet (e.g. ad libitum): ad libitum
- Water (e.g. ad libitum): ad libitum
- Acclimation period: at least 5 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19.5 – 21.6
- Humidity (%): 31 - 71
- Air changes (per hr): 15
- Photoperiod (hrs dark / hrs light): 12/12
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 5 mg/mL and 30 mg/mL
- Amount of vehicle (if gavage): 10mL/kg bw
- Justification for choice of vehicle: The vehicle was selected based on trial formulations performed at NOTOX and on test substance data supplied by the sponsor.
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg bw
DOSAGE PREPARATION (if unusual): The formulations (w/w) were prepared within 4 hours prior to dosing. The concentration of the test substance in vehicle was varied to allow constant dosage volume in terms of ml/kg body weight. Adjustment was made for specific gravity of the vehicle. Homogeneity was accomplished to a visually acceptable level.
In order to obtain homogeneity, the formulations were heated in a water bath with a maximum temperature of 42 °C for a maximum of 13 minutes. The formulations were allowed to cool down to a temperature of maximally 40 °C prior to dosing.
CLASS METHOD (if applicable)
The toxicity of the test substance was assessed by stepwise treatment of groups of 3 females. The first group was treated at a dose level of 300 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:
- 300, 50 and 50 mg/kg bw
- No. of animals per sex per dose:
- 3
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 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.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- 50 - 300 mg/kg bw
- Mortality:
- Two females at 300 mg/kg were found dead and one female at 300 mg/kg was sacrificed for ethical reasons on Day 1.
No mortality occurred among the animals at 50 mg/kg. - Clinical signs:
- other: Clinical signs observed during the study period were as follows: 300 mg/kg: Lethargy, hunched posture, uncoordinated movements, piloerection. 50 mg/kg: Hunched posture, piloerection. The surviving animals had recovered from the symptoms by Day 3.
- Gross pathology:
- Macroscopic post mortem examination of the animals that were found dead or sacrificed for ethical reasons during the study revealed dark red and/or black discolouration of the glandular mucosa of the stomach.
No abnormalities were found at macroscopic post mortem examination of the animals at 50 mg/kg. - Other findings:
- None.
- Interpretation of results:
- Category 3 based on GHS criteria
- Conclusions:
- The oral LD50 value of LiPF6 in Wistar rats was established to be within the range of 50-300 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to be 200 mg/kg body weight.
Based on these results:
- according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2004), LiPF6 should be classified as: Toxic if swallowed (Category 3) for acute toxicity by the oral route.

Additional information
Key study giving a reliable result.
Justification for selection of acute toxicity – inhalation endpoint
Study not required: substance is corrosive.
Justification for selection of acute toxicity – dermal endpoint
Study not required: substance is corrosive.
Justification for classification or non-classification
Evidence of an acute oral LD50 between 50 and 300 mg/kg triggers classification as Acute Toxicity 3, H301 under CLP regulation (1272/2008).
