Bayferrox VP AC 5122 M
Constituent 2
Reference substance name:
iron(III) oxide
IUPAC Name:
iron(III) oxide
Details on test material:
Bayeferrox VP AC 5122 M: Fe2O3 83.5 %, FeO 12%, Co 4.5%

Test animals / tissue source

Species:
rabbit
Strain:
New Zealand White
Details on test animals or tissues and environmental conditions:
Male rabbits were kept under standardised conditions in individual cages at a temperature between 19 and 15oC and a relative humidity between 40 and 60%. The animals weighed between 3 and 4 kg. The day/night rhytm was 12/12 hrs. The animals were fed with a standard diet and were allowed to drink tap water ad libitum.

Test system

Vehicle:
unchanged (no vehicle)
Controls:
other: One eye was treated, one eye served as a control.
Amount / concentration applied:
100 mg fine powdered
Duration of treatment / exposure:
168 hours

Observation period (in vivo):
analog duration of treatment

Number of animals or in vitro replicates:
3
Details on study design:
Every animal was treated with 100 mg of fine powdered sample in the conjunctival sac of the eye. After application the eye was kept close for 1 second. After 24 hrs the treated eye was rinsed with a physiological salt solution. The other eye was not treated and served as a control.

Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Not irritating
Executive summary:

In an eye irritation study, 100 mg of Bayeferrox VP AC 5122 M (a mixture consisting of Fe2O3 83.5 %, FeO 12%, Co 4.5%) was instilled into the conjunctival sac of the eye of 3 rabbits, according to OECD guideline 405. Animals were observed for a total of 168 hrs.  This study showed that Bayeferrox VP AC 5122 M is not eye irritating.
