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.
