- TEST ANIMALS- Weight at study initiation: average male weight 196 g, average female weight 158 g- Age: 7 weeks- Fasting period before study: 22 h - Housing: single animale per cage- Diet: commercial pelleted diet (Oakes Special Diet with added Vit. C) ad libitum- Water: tap water ad libitum ENVIRONMENTAL CONDITIONS- Temperature (°C): 21 ± 2- Photoperiod (hrs dark / hrs light): 12 h light / 12 h dark
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Doses:
- Single dose: 25% of solution of teh compound in tap water was administrated with a single dose by gavage to rate which had been fasted for 18 hours at a rate of 20ml/kg equivalent to 5000 mg/kg of the compound.
- Control animals:
- not specified
- Statistics:
- Not applicable.
- Sex:
- female

- LD50
- Effect level:
- > 5 000 mg/kg bw
- Based on:
- act. ingr.
- Mortality:
- No mortality
- Clinical signs:
- other: Compound passed through the gastro intestinal tract within 12 hours of administration and some was still visible in the faeces after 24 hours.
- Gross pathology:
- No change in any organs and tissues.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- LD50 > 5000 mg/kg bw.
- Executive summary:
The results show no toxicity with a LD 50 value > 5000 mg/kg.
Reference
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- LD50
- Value:
- 5 000 mg/kg bw
Acute toxicity: via inhalation route
Endpoint conclusion
- Endpoint conclusion:
- no study available
Acute toxicity: via dermal route
Endpoint conclusion
- Endpoint conclusion:
- no study available
Additional information
No Adverse Effect level for acute toxicity
oral is LD50 > 5000 mg/kg.
NOAEL value for acute inhalation was not determined due to the absence
of effects during the test.
Justification for classification or non-classification
According to the CLP Regulation (EC n. 1272/2008), table 3.1.1, Acute toxicity hazard categories and acute toxicity estimates (ATE) defining the respective categories:
For Acute toxicity oral route:
Category 1: ATE <= 5 mg/kg bw
Category 2: 5 < ATE <= 50 mg/kg bw
Category 3: 50 < ATE <= 300 mg/kg bw
Category 4: 300 < ATE <= 2000 mg/kg bw
The LD50 of the test substance was
determined to be > 2000 mg/kg bw in the chosen reference test, which is
outside the above criteria.
There were no effects in the acute inhalation toxicity test.
Therefore, the test substance is not classified for Acute toxicity by oral exposure and inhalation.
No classification for acute toxicity oral is warranted under Regulation 1272/2008.
No classification for acute toxicity inhalation is warranted under Regulation 1272/2008.
