Details on test animals or test system and environmental conditions:

TEST ANIMALS
- Source: Charles River Deutschland, Sulzfeld, Germany
- Age at study initiation: Young adult animals (approx. 10 weeks old) were selected.
- Weight at study initiation: mean males: 305g, mean females:197g
- Fasting period before study: Not applicable
- Housing: Individually housed in labeled Macrolon cages (MIII type, height 18 cm.) containing sterilized sawdust as bedding material (Litalabo, S.P.P.S., Argenteuil, France) and paper as cageenrichment (Enviro-dri, Wm. Lillico & Son (Wonham Mill Ltd), Surrey, United Kingdom). Acclimatization period was at least 5 days before start of treatment under laboratory conditions. During the acclimatization period the animals were group housed in Macrolon cages (MIV type).
- Diet (e.g. ad libitum): Free access to pelleted rodent diet (SM R/M-Z from SSNIFF® Spezialdiäten GmbH, Soest, Germany).
- Water (e.g. ad libitum): Free access to tap water.
- Acclimation period: At least 5 days before start of treatment under laboratory conditions.

ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19.5 - 21.3ºC
- Humidity (%): 46 - 81%
- Air changes (per hr): 15
- Photoperiod (hrs dark / hrs light): 12/12

IN-LIFE DATES: 19 August 2010 - 02 September 2010

Administration / exposure

Type of coverage:

occlusive

Vehicle:

unchanged (no vehicle)

Details on dermal exposure:

TEST SITE
- Area of exposure: back
- % coverage: 10% of the total body surface, i.e. approx. 25 cm² for males and 18 cm² for females.
- Type of wrap if used: The test substance was held in contact with the skin with a dressing, consisting of a surgical gauze patch (Surgy 1D), successively covered with aluminum foil and Coban elastic bandage. A piece of Micropore tape was additionally used for fixation of the bandages in females only.

REMOVAL OF TEST SUBSTANCE
- Washing (if done): Dressings were removed and the skin cleaned of residual test substance using tap water.
- Time after start of exposure: 24 hours

TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 2000 mg/kg (4.517 mL/kg) body weight. Dose volume calculated as (dose level (g/kg) / density (g/mL)) x (100/35), i.e. taking into account the purity of the test substance (35%).

Duration of exposure:

24 hours

Doses:

2000 mg/kg bw/day

No. of animals per sex per dose:

5

Control animals:

no

Details on study design:

- Duration of observation period following administration: 14 days
- 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 time of onset, degree and duration were recorded and the symptoms graded according to fixed scales:
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: 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:

None

Results and discussion

Effect levels

Sex:

male/female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Based on:

test mat.

Remarks on result:

other: No effects observed.

Mortality:

No mortality occurred.

Clinical signs:

One male showed flat posture on Day 1. Green staining of the treated skin and/or flank was seen in the animals during the observation period

Body weight:

The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity.

Gross pathology:

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

Applicant's summary and conclusion

Interpretation of results:

study cannot be used for classification

Remarks:

Migrated information

Conclusions:

The dermal LD50 value of Complexation products of sodium tartrate with iron trichloride in Wistar rats was established to exceed 2000 mg/kg body weight.

Executive summary:

Assessment of acute dermal toxicity with Complexation products of sodium tartrate with iron trichloride in the rat.

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

OECD No.402 (1987) "Acute Dermal Toxicity"

Commission Regulation (EC) No 440/2008, B3: "Acute Toxicity (Dermal)"

EPA, OPPTS 870.1200 (1998), "Acute Dermal Toxicity"

JMAFF Guidelines (2000), including the most recent revisions.

Complexation products of sodium tartrate with iron trichloride 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. One male showed flat posture on Day 1. Green staining of the treated skin and/or flank was seen in the animals during the observation period. The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity. No abnormalities were found at macroscopic post mortem examination of the animals. The dermal LD50 value of Complexation products of sodium tartrate with iron trichloride in Wistar rats was established to exceed 2000 mg/kg body weight.
