Test animals

Details on test animals or test system and environmental conditions:
Rat, Wistar strain Crl:WI (outbred, SPF-Quality). Recognised by international guidelines as the recommended test system (e.g. OECD, EC).
Source: Charles River Deutschland, Sulzfeld, Germany.

Administration / exposure

Route of administration:
oral: gavage
propylene glycol
Details on oral exposure:
using plastic feeding tubes
single dosage, on Day 1
2000 mg/kg (10 ml/kg) body weight
300 mg/kg (10 ml/kg) body weight
No. of animals per sex per dose:
Number of animals: 9 females (nulliparous and non-pregnant). Each dose group consisted of 3 animals
Details on study design:
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 2000 mg/kg. The absence of 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 toxicty were taken into account for determinaton of the time interval between the dose groups.

Results and discussion

Effect levels
Key result
Dose descriptor:
Effect level:
> 300 - < 2 000 mg/kg bw
The incidence of mortality was as follows, presented in chronological order of treatment:

Dose level Mortality Date of Treatment
2000 mg/kg 3/3 26 November 2006
300 mg/kg 1/3 31 November 2006
300 mg/kg 0/3 02 December 2006

The decedents were found between days 1 and 2 post-treatment.
Clinical signs:
Clinical signs observed during the study period were as follows:

Dose level Clinical signs
2000 mg/kg lethargy, hunched posture, laboured respiration, piloerection and ptosis
300 mg/kg lethargy, hunched posture, uncoordinatored movements, piloerections and ptosis

The surviving animals had recovered form the symptoms between days 2 and 3.
Body weight:
The body weights gain shown by the surviving animals over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain.
Other findings:
Microscopic findings: no abnormalities were found at macroscopic post mortem examinations of the animals.

Applicant's summary and conclusion

Interpretation of results:
Category 4 based on GHS criteria
The Oral LD50 value of SXJUL2006 in Wistar rats was established to be within the range of 300-2000 mg/kg body weight.
