Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In a good quality acute oral toxicity study (reliability score 1) conducted to OECD test guideline 423, and GLP, the LD50 for Crude Tall Oilwas greater than 2000 mg/kg bw in Crl:CD(SD)IGS BR rats.
- Executive summary:
Crude Tall Oil was administered once as a solution in corn oil (10 ml/kg bw), given orally via gavage to female Crl:CD(SD)IGS BR rats. The dosing was performed sequentially to groups of three animals per step using a starting dose of 300 mg/kg bw and 2000 mg/kg bw as the second dose. The animals were then observed for 14 days. Clinical observations were noted at least once per day, body weights were recorded before administration, and on days 7 and 14. At the end of the observation period all animals were sacrificed and necropsied. There were no clinical signs of toxicity, no deaths and all animals gained weight normally. The oral LD50 was therefore greater than 2000 mg/kg bw.
