- Humidity (%): 40-70
- Air changes (per hr): approx.15
- Photoperiod (hrs dark / hrs light): 12/12


IN-LIFE DATES: 19 July 2010 - 02 Augustus 2010

Administration / exposure

Route of administration:

oral: gavage

Vehicle:

unchanged (no vehicle)

Details on oral exposure:

MAXIMUM DOSE VOLUME APPLIED: Dose volume (mLlkg body weight) is calculated as follows: Dose level (g/kg) / spec.gravity or density (g/ml). Animals were given 1-2 ml/kg

CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: Based on anticipated absence of toxicity at 2000 mg/kg.

Doses:

2000 mg/kg bw

No. of animals per sex per dose:

2000 mg/kg: two group of 3 females

Control animals:

no

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Observations: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15. Weighing: Days 1 (pre-administration), 8 and 15 and at death (if found dead after Day 1).
- Necropsy of survivors performed: yes
- Other examinations performed: none.

Statistics:

Not applicable.

Results and discussion

Preliminary study:

Not applicable

Effect levels

Sex:

female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Mortality:

No mortalities

Clinical signs:

Clinical signs observed during the study period were as follows:
Dose level Clinical signs
2000 mg/kg Hunched posture, piloerection on day 1

Body weight:

The mean body weight gain shown by the animals at 2000 mg/kg over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain.

Gross pathology:

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

Other findings:

None.

Applicant's summary and conclusion

Interpretation of results:

study cannot be used for classification

Remarks:

Migrated information

Conclusions:

The oral LD50 value of the test substance was > 2000 mg/kg body weight.

Executive summary:

Assessment of acute oral toxicity with Complexation products of sodium tartrate with iron trichloride in the rat (Acute Toxic Class Method).

The study was carried out based on the guidelines described in:

OECD No.423 (2001) "Acute Oral Toxicity, Acute Toxic Class Method"

Commission Regulation (EC) No 440/2008, B1 tris: "Acute Oral Toxicity, Acute Toxic Class Method"

EPA, OPPTS 870.1100 (2002), "Acute Oral Toxicity"

JMAFF guidelines (2000) including the most recent partial revisions.

Complexation products of sodium tartrate with iron trichloride was administered by oral gavage to two subsequent groups of three female Wistar rats at 2000 mg/kg body weight, taking into account the purity of the test substance (35%). Animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed after terminal sacrifice (Day 15).

No mortality occurred.

Hunched posture and/or piloerection was observed for all animals on Day 1. The 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 the animals. The oral LD50 value of Complexation products of sodium tartrate with iron trichloride 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.
