Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- GLP compliance:
- yes (incl. QA statement)
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- A guinea pig sensitisation study was conducted to evaluate the sensitisation potential of the test item 1,l' - Bis(ferrocenyl)octane. The study was performed according to Magnusson and Kligman.
Test material
Constituent 1
- Specific details on test material used for the study:
- Read across data is presented from the structurally related substance, 1,1'-Bis(ferrocenyl)octane, CAS Number 501410-94-2, EC Number 479-710-1. This substance bears a close structural similarity to 1,1"-isopropylidenebis(ethylferrocene), CAS Number 37206 -42 -1, EC Number 310 -202 -3, the distinction being that the alkyl bridging functionality between the two ferrocene moieties is an octyl derivative as opposed to an isopropyl derivative and that two cyclopentadienyl moieties in the target substance bear ethyl substituents.

Any other information on results incl. tables
Maximum concentration not causing irritating effects in preliminary test: 100 %.
Signs of irritation during induction:
No reaction on the skin of guinea pigs was observed.
Evidence of sensitisation of each challenge concentration:
After the challenge with test item 1,1'-Bis(ferrocenyl)octane
in undiluted form a positive response was not observed in
the animals of the test group.
Other observations:
No effects on mean body weight and body weight development were noted.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a study conducted according to OECD guideline 406, 1,1'-Bis(ferrocenyl)octane was found to be not sensitising to the skin.
- Executive summary:
The skin sensitisation potential of 1,1'-Bis(ferrocenyl)octane, CAS Number 501410-94-2, EC Number 479-710-1was investigated in accordance with the standardised guideline OECD 406.
An OECD 406 study conducted to GLP in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results was performed on 1,1'-Bis(ferrocenyl)octane, CAS Number 501410-94-2, EC Number 479-710-1.
The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
This substance is considered to be sufficiently close in structural integrity to 1,1"-isopropylidenebis(ethylferrocene), CAS Number 37206 -42 -1, EC Number 310 -202 -3 so as to justify valid read across.
Under the conditions of the study 1,1'-Bis(ferrocenyl)octane was found to be not sensitising to skin. The GHS criteria were not met.
