- No. of animals per sex per dose:
- range-finding study: 1 female animal per dose
main study: 2 female animals per dose - Control animals:

- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Animals were observed individually 30 minutes, 2 h, 4 h and 6 h after dosing, and once each day for 14 days thereafter for systemic toxic signs. The body weight was recorded on day 0 (shortly before the treatment) on day 7 and on day 15 before sacrifice on all animals with a precision of 1 g in the main study.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight
Results and discussion
- Preliminary study:
- range finding study:
No mortality occurred after the 24-hour dermal exposure to Sika Hardener MH in three female rats during the range-finding study. The initial dose was 200 mg/kg bw. The other doses were as 1000 mg/kg bw and 2000 mg/kg bw, respectively.
Effect levels

- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- In the main study, the dose of 2000 mg/kg bw was applied to two further animals. There was no mortality in main study, too.
- Clinical signs:
- other: No behavioural changes or systemic toxic signs were noted during the study. Dermal irritation symptoms as erythema and other signs as dry skin surface, wound, small wound/s and crust were observed on the treatment site. 200 mg/kg bw There was not any derm
- Gross pathology:
- All animals survived until the scheduled necropsy on Day 15.
External macroscopic changes were observed connected with local irritation symptoms. Erythema, wound and crust were observed on the treated skin surface in all animals of 2000 mg/kg bw dose.
Severe hydrometra was observed in animal No.: 5226 of 200 mg/kg bw dose and in animal No.: 5227 of 1000 mg/kg bw dose. Besides, moderate hydrometra was found in animal No.: 5230 of 2000 mg/kg bw dose. Hydrometra is a physiological finding and connected to the oestrus cycle of the animal.
No macroscopic alterations related to the systemic toxic effects of the test item were found. - Other findings:
- - Organ weights: not examined
- Histopathology: not examined
- Potential target organs: no

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In this acute dermal toxicity study with the test item, the obtained acute dermal LD50 value was greater than 2000 mg/kg bw in Han:WIST female rats.
- Executive summary:
An acute dermal toxicity study was performed with test item in Han:WIST rats, in compliance with OECD Guideline No. 402 and OPPTS 870.1200. At first, the range-finding study was performed. The starting dose was 200 mg/kg bw using one animal. The other doses were 1000 and 2000 mg/kg bw applying one animal, each. No death was observed. Therefore, 2000 mg/kg bw dose was used in the main study. The test item was applied to three animals in original form, i. e. without vehicle,and left in contact with the skin for 24 hours, followed by a 14-day observation period. No death was observed in the 2000 mg/kg bw dose group in the main study. Animals treated with 2000 mg/kg bw of the test item did not show behavioral changes and no signs of systemic toxicity were noted during the study. The test item caused dermal irritation symptoms as well as defined or slight erythema between Day 1 and Day 14. Other dermal irritation symptoms as dry skin, small wound, crust and wound were recorded between Day 2 and Day 14. Mean body weight development was within the normal range for animals of this strain and age in the main study. No macroscopic alterations of organs and tissues referring to systemic toxicity of the test item were seen during the necropsy. It is to be noted that the test item caused dermal irritation response on the site of administration.
In this acute dermal toxicity study with the test item, the obtained acute dermal LD50 value was greater than 2000 mg/kg bw in Han:WIST female rats.
