Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Tthe LD50 of the test item DERTOL 90 is higher than 2000 mg/kg body weight. Therefore it should not be classified according to CLP Regulation (EC) No 1272/2008.
- Executive summary:
Acute dermal toxicity study of Terpineol multiconstituent as a limit test was conducted according to OECD guideline 402 and in compliance with GLP. To groups of 5 Sprague-Dawley rats/sex were used: one control group exposed to distilled water and one test group. The test substance was applied to the skin by topical application for 24 h, under semi-occlusive conditions, at 2000 mg/kg bw, with a volume of 2.13 mL/kg bw. After exposure, exposure area was washed with distilled water.
Animals were observed every day for systemic clinical signs and mortalities for 14 days. The animals were weighed on D0, D2, D7 and D14. Necropsies were done on D14 for macroscopic observations. No toxic effects were observed.
Based upon these experimental conditions, the LD50 of Terpineol multiconstituent is higher than 2000 mg/kg bw by dermal route in the rat,
and Terpineol multiconstituent should not be classified according to CLP Regulation (EC) No 1272/2008.
