ANALYSIS
- Conduct of analyses: Samples of the test-item formulation were sent to the sponsor for analysis (BASF SE, Z470, 67056 Ludwigshafen, Germany).
- Stability of the test item preparation: The stability of the test item in the vehicle will determined indirectly by concentration control analysis. For this purpose, the samples taken were stored at room temperature over the maximum duration of the administration period, subsequently deep-frozen and sent to the sponsor for analysis.
- Homogeneity of the test item preparation: The homogeneity of the test item preparation will be determined indirectly by concentration control analysis.
- Concentration control analysis of the test item preparation: A concentration control analysis of the test item preparation and archiving of the respective data will be done by the sponsor.
- Analysis of feed: The feed used in the study was assayed for chemical and microbial contaminants by the manufacturer in quarterly intervals.
- Analysis of drinking water: The drinking water was regularly assayed for contaminants by the municipal authorities of Heidelberg. The German Drinking Water Regulation of Dec. 5, 1990 served as the guideline for maximum tolerable contaminants.
- Bedding and enrichment analysis: The bedding and enrichment were regularly assayed for contaminants (chlorinated hydrocarbons and heavy metals).
EXPERIMENTAL PROCEDURE
- Observation period: 14 days
- Body weight determination: shortly before administration (day 0), weekly thereafter and on the last day of observation.
- Clinical observations: several times on the day of administration, and at least once daily thereafter each workday for the individual animals.
- Scoring of skin findings: Individual readings 30 – 60 minutes after removal of the semi-occlusive dressing (day 1), weekly thereafter and on the last day of observation.
- Mortality: A check for any dead or moribund animals was made at least once each workday.
- Pathology: Necropsy with gross-pathology examination on the last day of the observation period after sacrifice with CO2 in a chamber with increasing concentrations over time.
- Assessment of skin reactions: The evaluation of skin reactions was performed according to Draize, J.H. (1959): Appraisal of the safety of chemicals in foods, drugs and cosmetics. The association of food and drug officials of the United States Austin, Texas. - Key result

Additional information
Oral toxicity
In an acute oral toxicity study comparable to OECD guideline 401 (BASF, VIII/56, 1958), rats were exposed to dose levels of 20, 79, 316, 1260 and 5010 mg/kg bw of the substance by gavage and observed for 7 days. The highest dose was tested with 10 animals, the other doses were tested with 1 animal. No mortality and no clinical signs were observed. Gross pathology revealed blood congestion in the liver and spleen in 4 animals at the high dose. The LD50 was determined to be >5010 mg/kg bw.
Dermal toxicity
In a GLP acute dermal toxicity study (Limit Test), according to OECD 402 (Bioassay, 11-BF-DT109, 2012), young adult Wistar rats (5 males and 5 females) were dermally exposed to a single dose of 2000 mg/kg bw of the test substance (as suspension in deionized water) to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours. The application area comprised at least 10 % of the total body surface area. The animals were observed for 14 days.
No mortality
occurred. No signs of systemic toxicity or skin effects were observed in
the animals. The mean body weight of the animals increased within the
normal range throughout the study period. No macroscopic pathologic
abnormalities were noted in the animals examined at the end of the study.
Accordingly, the acute dermal median lethal dose (LD50) was
determined to be LD50, dermal, rat > 2000 mg/kg bw.
Inhalation toxicity
In accordance with column 2 of REACH Annex VIII-X, in addition to the oral route, for substances other than gases, an acute toxicity study for at least one other route is required. The choice of the second route will depend on the nature of the substance and the likely route of human exposure. As dermal is the most likely route of exposure and acute dermal toxicity data is available, no data gap exists.

Regulation (EC) No 1272/2008
The available experimental test
data are reliable and suitable for classification purposes under
Regulation (EC) No 1272/2008. Based on available data on acute toxicity,
the test item is not classified according to Regulation (EC) No
1272/2008 (CLP).
