TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.1 ml (approximately 92 mg)- Duration of treatment / exposure:
- Eyelids were briefly closed for about one second immediately after application and there was no subsequent washing to remove the test material.
- Observation period (in vivo):
- Severe ocular reaction resulted in humane sacrifice of the animal 48 hours after application of the test material.
- Number of animals or in vitro replicates:
- One male

- Washing (if done): the treated eye was not rinsed.
SCORING SYSTEM: Assessment of damage/irritation was made quantitatively and qualitatively using the Draize scale (see Attachment) at 1, 24 and 48 hours after application of the test substance into the eye. The ocular irritation potential was calculated from this assessment using a modified version of the Kay & Calandra system (see Attachment).
TOOL USED TO ASSESS SCORE: standard ophthalmoscope

- Irritant / corrosive response data:
- Iridial inflammation and moderate conjunctival irritation were seen one hour after application of the test material. Within 48 hours there was persistent iridial inflammation, moderate corneal opacity over most of the cornea, and severe conjunctival irritation (redness, swelling and discharge of the conjunctivae reached a maximum score on the Draize scale and sloughing of the conjunctival membrane was reported at 48 hours; see Table 1 for details.) Thereafter the rabbit was humanely sacrificed.
See attchment - Other effects:
- No systemic effects were reported.
Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye)
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In a guideline study, to GLP, instillation of ammonium hexachlororhodate (III) (0.1 mL; 92 mg) to the eye of a single male rabbit caused severe irritation that required sacrifice after 48 hr. No further animals were tested.
- Executive summary:
In an OECD Test Guideline 405 study, conducted according to GLP, ammonium hexachlororhodate (III) (0.1 mL; 92 mg) was instilled into the conjunctival sac of a single male New Zealand White rabbit and both lids were briefly closed. The other eye remained untreated and acted as the control. The treated eye was assessed, without rinsing, both quantitatively and qualitatively, for signs of irritation on the cornea, iris and conjunctiva using the Draize scale after 1, 24 and 48 hr post-application.
Severe irritation was observed, with symptoms including iridial inflammation, moderate corneal opacity and severe conjunctival redness, swelling and discharge. After 48 hr, the total irritation score was 65 (out of a maximum possible score of 110, based on the Draize scale) and sloughing of the conjunctival membrane was reported. The animal was humanely sacrificed and no further animals were tested. No systemic toxicity was observed.
As the results were based on only one rabbit, it is not possible to give a definitive interpretation according to EU CLP criteria (EC 1272/2008). However, it is considered prudent to classify the test material for serious eye damage (Category 1), as the severe effects observed are not expected to be reversible.
