Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the test conditions, CHIMEXANE HB should not be classified according to the criteria of the Annex VI of the Directive 67/548/EEC and the CLP Regulation (EC) N° (1272-2008).
- Executive summary:
CHIMEXANE HB was tested for acute dermal toxicity in Sprague-Dawley [Rj: SD (IOPS Han)] rats in a GLP-compliant limit dose assay according to OECD guideline 402. Groups of rats (5/sex) were administered a single dermal dose of undiluted test material at 2000 mg/kg bw on clipped skin (approximately 10 % of the total body surface area) using a semi-occlusive patch held in place for 24 h. Residual test item was removed using a moistened cotton pad at the end of the 24 h exposure period. Examinations for mortality, clinical signs, body weight gain and dermal reactions were performed during a 14-day observation period. All surviving animals were necropsied at the end of the observation period.
No deaths and clinical signs occurred during the observation period. When compared to historical control animals, a slightly reduced body weight gain was recorded in 1/5 males between Days 1 and 8 and in 3/5 males and 2/5 females between Days 8 and 15. Overall body weight gain of the other animals was similar to that of historical control animals. At necropsy, macroscopic examination of main organs showed no abnormalities. The acute dermal combined LD50 was greater than 2000 mg/kg bw.
Some dermal changes were observed in most of the animals. They consisted of erythema, edema, skin dryness and later crusts. An erythema was observed in all animals from Day 2 up to Day 4 in 1/5 males, Day 7 in 1/5 males and 1/5 females, Day 9 in 2/5 males and 1/5 females, Day 11 in 1/5 males and Day 12 in 3/5 females. An edema was observed in 4/5 males and 4/5 females from Day 2 up to Day 4. A dryness of the skin was observed in 4/5 males and 4/5 females from Day 5 ; it persisted up to Day 12 in 3/5 males and 4/5 females, and up to Day 13 in 1/5 males. Crusts were noted in 3/5 males and 4/5 females from Day 5 up to Day 7 in 3/5 males and 2/5 females, Day 9 in 1/5 females and Day 12 in 1/5 females.
Under the test conditions, CHIMEXANE HB should not be classified according to the criteria of the Annex VI of the Directive 67/548/EEC and the CLP Regulation (EC) N° (1272-2008).
