Description of key information
All key information presented in this section was conducted to (or is considered equivalent to) international testing guidelines. GLP certification is appropriate to the age of the studies and the testing dates.
Acute toxicity: inhalation
Data waiving, exposure considerations. The study need not be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles of an inhalable size.
Key value for chemical safety assessment
Acute toxicity: via oral route

- Conclusions:

- Executive summary:
In this study (equivalent to OECD 401), the acute oral LD50 of the test material (EC 239-263-3) was determined to be 6800 -10000 mg/kg bw (male & female) in the Rat. The LD50 is based upon the actual level of test material administered (gavage). The study was conducted prior to the adoption of GLP criteria and certification, but is considered reliable with restrictions (2) (according to Klimisch et al, 1997) based upon the level of reporting. This LD50 value is outside the range for classification as an acute toxic substance according to EU regulation 1272/2008.

Individual body weight will be determined shortly before test item administration, at weekly intervals thereafter and before the sacrifice of the animals at the end of the observation period. Moreover, the body weights of animals that die or are sacrificed in a moribund state will be determined from study day 1, onward. A check for moribund and dead animals will be made at least once each workday.

- Other findings:
- In all male animals well-defined erythema (grade 2) was noted on study day 1 and persisted in four of these animals until study day 3. Thereafter, very slight erythema (grade 1) was noted in these four animals from study day 6 until study day 7 or 8. In the fifth animal very slight erythema was seen from day 2 until day 8. Very slight edema (grade 1) was noted in all male animals on study day 1 only. Scaling was noted in three male animals from study day 7 or 8 until study day 10 after application.
In two females well-defined erythema (grade 2) was noted on study day 1, but decreased to very slight erythema (grade 1) in one of these animals and was noted from study day 2 until study day 7. In these two females very slight edema (grade 1) was seen on study day 1 after application only.
In the three remaining female animals very slight erythema (grade 1) was noted on study day 1, only. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material has an LD50 of >2000 mg/kg bw for acute dermal toxicity. This test value does not fulfill the criteria for classification and labelling according to EU regulation 1272/2008.
- Executive summary:
In this guideline study (OECD 403) conducted with GLP certification, the acute dermal LD50 of the test material (EC 239-263-3) was determined to be >2000 mg/kg bw in the Rat. Test animals were exposed for 24 hours with a semiocclusive bandage. The test material was administered unchanged. The test material is not classified as acutely toxic according to the EU Classification, Labelling, and Packaging (CLP) regulation (1272/2008), based upon this result.

Additional information
Acute Toxicity: Oral
The test item was administered by gavage to male and female Wistar rats at concentrations of 10000, 6810, 4640, 3160 mg/kg bw. The animals were observed for 14 days. Mortality, body weight and clinical signs were recorded continuously. Organ weighing and gross necropsy was performed after scheduled sacrifice. Mortality occurred at the highest dose level. Body weight and body weight gain were comparable to control animals. All animals of the 10.000 mg/kg bw group showed apathy and staggering until day two after application. Prone/lateral position was seen until 2 hours after application of test substance. 2 hours after application animals showed atonia, narcotic like symptoms and loss of pain reflex. Until day 2 after application all animals showed piloerection and smeared fur within urine. Salivation was seen until 30 min after application. The animals showed a bad general state of health until day 2 after application. At 6810 mg/kg all animals showed apathy and staggering until 4-5 hours after application. Until 5 hours after application all animals showed redness of skin. Exphtalmia was seen the first 30 minutes after application. The animals showed a bad general state of health until 5 hours after application. All animals of the 4640 mg/kg bw group showed apathy and staggering until 1-2 hours after application. Exphtalmia was seen the first 15 minutes after application. The animals showed a bad general state of health until 2 hours after application. At 3160 mg/kg, all animals showed staggering until 1 hour after application. The animals showed a light bad general state of health until 1 hour after application. The LD50 is therefore considered to be > 5000 mg/kg bw.
Acute Toxicity: Dermal
In an acute dermal toxicity study (Limit Test), young adult Wistar rats(5 males and 5 females)were dermally exposed to a single dose of 2000 mg/kg bw of the undiluted test item to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semi-occlusive dressing for 24 hours (OECD 402, GLP). The application area comprised at least 10% of the total body surface area. The animals were observed for 14 days. No mortality occurred. No clinical signs were observed. 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.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is not considered to be classified for acute oral toxicity under Regulation (EC) No. 1272/2008.
