Toxicological information
Eye irritation
Currently viewing:
Administrative data
- Endpoint:
- eye irritation: in vivo
- Type of information:
- migrated information: read-across based on grouping of substances (category approach)
- Adequacy of study:
- weight of evidence
- Study period:
- 18 Dec 1981 - 25 Jan 1982
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Comparable to guideline study with acceptable restrictions; due to a complete lack of reactions the observation period was stopped after 24 h; analytical purity data on test substance was not given.
