- Fasting period before study: Approx. 16 hours before administration; only tap water will be then available ad libitum.
- Housing: During the 14-day observation period the animals were kept singly in MAKROLON cages (type III plus). Granulated textured wood (Granulat A2, J. Brandenburg, 49424 Goldenstedt, Germany) was used as bedding material for the cages. The cages were changed and cleaned twice a week.

Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- physiological saline
- Remarks:
- aqua ad iniectabilia
- Details on dermal exposure:
- TEST SITE
- Area of exposure: The intact dorsal skin of the animals was shaved free of hair with a shaver without causing injury approximately 24 hours before application. The site was situated on the animals back between the fore and hind extremities and had an area of at least 5 cm x 6 cm.
- % coverage: approx. 10% (1/10 of body surface)
- Type of wrap if used: The test patch was occlusive. The test item was held in contact with the skin with 8 layers of gauze. The gauze was covered with a plastic sheet and secured with adhesive plaster on the application site for 24 hours.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): Yes. At the end of the exposure period, possible residual test item was removed where practicable using water or some other appropriate method of cleaning the skin.
- Time after start of exposure: 24 hours
TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 2000 mg active ingredient/kg bw
- For solids, paste formed: yes. 7011 mg Butanedioic acid, sulfo-, mono (C16-18 and C18-unsatd. alkyl)esters, ammonium sodium salts was moistened with 3505 mg aqua ad iniectabilia. Thereof 3120 mg/kg bw was applied. A correction factor of 1.04 was used. - Duration of exposure:
- 24 hours
- Doses:
- 2000 mg act. ingr./kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Observations were performed before and immediately, 5, 15, 30 and 60 min, as well as 3, 6 and 24 hours after administration. All animals were observed for a period of 14 days.
During the follow-up period (2 weeks) changes in skin and fur, eyes and mucous membranes, and the respiratory, circulatory, autonomic and central ner¬vous system and somatomotor activity as well as behaviour pattern were observed at least once a day until all symptoms subsided, thereafter each working day. Attention was also paid to possible tremors, convulsions, salivation, diarrhoea, lethargy, sleep and coma..
Observations on deaths were made at least once daily to minimize loss of animals during the study. Individual body weights were recorded before administration of the test item and thereafter in weekly intervals up to the end of the study. Changes in weight were calculated and recorded.
- Necropsy of survivors performed: yes. At the end of the experiments, all animals were sacrificed, dissected and inspected macroscopically. All gross pathological changes were recorded. No histopathology was carried out as no macroscopical findings were noted at necropsy.
- Other examinations performed: clinical signs, body weight, other: The skin was observed for the development of erythema and oedema . - Statistics:
- The LD50 could not be calculated as no animal died prematurely.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- According to the EC-Commission directive 67/548/EEC and its subsequent amendments on the approximation of the laws, regulations and administrative provision relating to the classification, packaging and labelling of dangerous substances and the results obtained under the present test conditions the test item containing 95.8% active ingredient requires no labeling (as LD50 > 2000 mg/kg bw).
Also, according to the EC Regulation 1272/2008 and subsequent regulations, the test item is not classified for acute dermal toxicity. - Executive summary:
Test item containing 95.8% active ingredient was tested in a acute dermal toxicity study. A single dermal administration of 2000 mg act.ingr. /kg bw to 5 male and 5 female CD rats for 24 hours under an occlusive patch,revealed no signs of toxicity and no deaths. A very slight erythema (barely perceptible) on the application site was observed in 5 of 5 male and 5 of 5 female animals on test days 2, 3 and 4. All animals gained the expected body weight throughout the whole experimental period.
According to the EC-Commission directive 67/548/EEC and its subsequent amendments on the approximation of the laws, regulations and administrative provision relating to the classification, packaging and labelling of dangerous substances and the results obtained under the present test conditions the test item containing 95.8% active ingredient requires no labeling (as LD50 > 2000 mg/kg bw).
Also, according to the EC Regulation 1272/2008 and subsequent regulations, the test item is not classified for acute dermal toxicity.
