Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred after the 24-hour dermal exposure to the test item in Crl(WI) male and female rats during the study.
- Clinical signs:
- other: No behavioural changes or systemic toxic signs were noted during the study. Dermal irritation symptoms as erythema, oedema and other signs as desquamation, wounds and crusting were observed on the treatment site. Very slight (score 1) and/or well defined
- Gross pathology:
- All animals survived until the scheduled necropsy on Day 15.
Internal macroscopic changes were observed. A seminal vesicle atrophy was detected in male animal No.: 2981 on the right side. Ovary cyst was seen in female No.: 2925 on the right side and severely wide section of uterus was detected in same female. These alterations could not be related to the test item toxic effect, but were regarded an individual variation. Most likely the observations are a congenital anomaly.
Moderate hydrometra was observed in female No.: 2926. Hydrometra is a physiological finding and connected to the cycle of the animal.
No macroscopic alterations due to the systemic toxic effects of the test item were found.
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 Crl(WI) male and female rats. According to Regulation (EC) No 1272/2008 and UN GHS, the test item has not been classified into any category.
On the other hand, it is to be noted that the test item caused dermal irritation response on the site of administration. - Executive summary:
An acute dermal toxicity study was performed with the test item in Crl(WI) rats, in compliance with OECD Guideline No. 402 and OPPTS 870.1200 and GLP.
A limit test was carried out. A single group of male and female animals (n=5 animals/sex) was exposed to the test item at 2000 mg/kg bw by dermal route. The test item was applied in undiluted form and left in contact with the skin for 24 hours, followed by a 14-day observation period.
No mortality occurred after the 24-hour dermal exposure to the test item in male and female rats during the study.
Neither male nor female animals treated with 2000 mg/kg bw of the test item showed behavioural changes and no systemic toxic signs were noted during the study. The test item caused dermal irritation symptoms in both sexes. Very slight and well defined erythema was observed in males between Day 1 and Day 10 and very slight erythema was found in females between Day 1 and Day 5. Erythema occurred in all animals. Very slight oedema was recorded in two males on Day 4. Other dermal irritation symptoms as desquamation, wounds and crusting occurred in four males between Day 4 and Day 9.
Mean body weight development was within the normal range for male animals of this strain and age. Slight body weight loss was observed in one female on first week. It was not evaluated as a toxic effect of the test item.
No macroscopic alterations of organs and tissues referred to a systemic toxic effect of the test item were seen during the necropsy.
In this acute dermal toxicity study with the test item, the obtained acute dermal LD50 value was greater than 2000 mg/kg bw in Crl(WI) male and female rats. According to Regulation (EC) No 1272/2008 and UN GHS, the test item has not been classified into any category.
On the other hand, it is to be noted that the test item caused dermal irritation response on the site of administration.
