Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Skin sensitisation

Administrative data

Endpoint:
skin sensitisation: in vivo (non-LLNA)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1981
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study
Justification for type of information:
The study was conducted in the early days of GLP prior to guidelines. The Kodak laboratory used a proprietary in-house method for sensitization called the "footpad method" that was later specifically covered under OECD 406. While documentation is lacking due to the era in which it was conducted, the work was performed at a superior facility and the conclusions are not under question.

Any other information on results incl. tables

Sensitization testing was conducted in 1980/1981, at the start of GLP. As a result, the reports are generally under-reported, as standards for report content had not yet been set. The report exists as more of a short summary of the findings, while the primary details of the conduct were kept in generic standard operating proceedures that were applicable to each type of study. As such, individual numeric evaluations were not available for these tests, and the results are reported out in a more general qualatative description. The values for the results provided here are not real and are only placeholders as TCC demanded some sort of entry, even if one was not available.

The laboratory where this work was conducted was the state of the art at the time, and was one of the top labs in the world. We have no reason to doubt the results of the studies, but the findings are not reported out in such way that they are very applicable to entry as a robust summary today.
