Eye irritation
Administrative data
- Endpoint:
- eye irritation: in vivo
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 22 Dec 2011- 07 Jan 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see “remarks”
- Remarks:
- GLP-Guideline study. According to the ECHA guidance document “Practical guide 6: How to report read-across and categories (Dec 2012)”, the reliability was changed from RL1 to RL2 to reflect the fact that this study was conducted on a read-across substance.
- Justification for type of information:
- refer to analogue justification provided in IUCLID section 13
