Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
eye irritation: in vivo
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Comparable to guideline with acceptable restrictions (partly limited documentation; 50 μl instead of 100 μl test substance instilled). Study sufficient for evaluation of this endpoint.

Data source

Reference Type:
study report
Title:
Unnamed
Year:

Report date:

Materials and methods

Principles of method if other than guideline:
Before OECD Guideline 405 was established, eye irritation was tested using an internal method (BASF test). White Vienna rabbits were used. Usually 50µl or mg of the test substance were applied to the conjunctival sac of one eye of 2 animals. The talcum-treated adjacent eye served as a control.
GLP compliance:
no
