Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute lethal oral dose to rats of DV6850 was demonstrated to be greater than 2000 mg/kg bodyweight in accordance with OECD Guideline No. 423. DV6850 is in accordance with DSD (Directive 67/548/EEC) or CLP Regulation (EC) No 1272/2008 "unclassified" and will not require labelling
- Executive summary:
This study was performed to assess the acute oral toxicity of DV6850 to the rat. The method followed was that described in EEC Methods for the determination of toxicity, Annex to Directive 96/54/EEC (Official Journal No, L248, 30,9,96). Part B, Method B.1 tris, "Acute toxicity (oral) - acute toxic class method" and OECD Guideline for Testing of Chemicals No.423 “Acute Oral Toxicity - Acute Toxic Class Method” Adopted 22 March 1996.
A group of three fasted female rats received a single oral gavage dose of the test substance, formulated in water for irrigation, at a dose level of 2000 mg/kg. As results at this dosage indicated the acute lethal oral dose of the test material to be greater than 2000 mg/kg bodyweight, in compliance with the study guidelines, a group of three fasted males was dosed at 2000 mg/kg to confirm results at this dosage and complete the study.
All animals were killed as scheduled and examined macroscopically on Day 15, the end of the observation period. No clinical signs of reaction to treatment were observed in any animal throughout the duration of the study. All animals were considered to have achieved satisfactory bodyweight gains throughout the study. No abnormalities were revealed at the macroscopic examination at study termination on Day 15.
The acute lethal oral dose to rats of DV6850 was demonstrated to be greater than 2000 mg/kg bodyweight. DV6850 is in accordance with DSD (Directive 67/548/EEC) or CLP Regulation (EC) No 1272/2008 "unclassified" and will not require labelling.
