Additional information
Acute oral toxicity:
Sumilizer GP was tested for acute oral toxicity according to EU Method, B.1 (standard acute method) and in compliance with GLP. The test item was dissolved in 0.5% aqueous carboxymethyl cellulose and applied by oral gavage to male and female Crj:CD (SD) IGS rats. Each 5 male and 5 female rats received a single dose of 2000 mg/kg bw or the corresponding vehicle. After administration, the animals were observed for a time period of 14 days to assess general health, body weight gain and mortality. At the end of the observation period and in case of mortality, gross necropsy was performed on all surviving and descendent animals.
No mortality was observed during the study period and there were no clinical signs of toxicity noted for any animal. In addition, all animals gained body weight as expected. At gross necropsy, retention of white substance in the urinary bladder was observed in 2/5 males of the control group and in 1/5 males at 2000 mg/kg bw. Retention of fluid in the uterine horn were found in 2/5 females at 2000 mg/kg bw. The findings were not attributed to treatment and considered as toxicologically not relevant.
Under the conditions of the test, the acute oral lethal dose (LD50) was > 2000 mg/kg bw for male and female rats.
Acute dermal toxicity:
Sumilizer GP was tested for acute dermal toxicity in male and female Wistar rats according to OECD guideline 402 and in compliance with GLP. The test item was dissolved in polyethylene glycol (PEG 300) and 4 mL/kg bw were applied to the clipped skin on the back of the animals. Each 5 animals per sex were exposed to the test item for 24 h to a limit dose of 2000 mg/kg bw under semi-occlusive conditions. After patch removal, the skin was flushed with lukewarm tap water and dried with disposable paper towels. During a 14-day observation period, all animals were observed for general health, body weight changes and mortalities. At study termination, all animals underwent necropsy.
No mortality occurred and no signs of systemic or local toxicity were observed throughout the whole study period. In addition, there was no treatment-related impairment of body weight development. Gross necropsy at study termination revealed no substance-related findings.
Under the tested conditions, the acute dermal LD50 in male and female rats was > 2000 mg/kg bw.
Justification for classification or non-classification
The available data on acute oral toxicity and acute dermal toxicity do not meet the criteria for classification according to Regulation (EC) No. 1272/2008, and are therefore conclusive but not sufficient for classification.
