Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The results obtained, under these experimental conditions, enable to conclude that the test item STRONTIUM OXALATE does not have to be classified in accordance with the Regulation EC No. 1272/2008 on classification, labelling and packaging of substances and mixtures.
No symbol and warning label are required. - Executive summary:
The test item STRONTIUM OXALATE was instilled, as supplied, into the eye of three New Zealand rabbits at the dose of 0.1 g.
The experimental protocol was established on the basis of the official method as defined in the O.E.C.D. Test Guideline No. 405 dated October 9th, 2017.
The ocular reactions observed during the study have been slight and totally reversible:
- at the conjunctivae level: a slight redness noted 1 hour after the test item instillation in all animal and totally reversible between Days 1 and 2. This reaction was associated with a slight chemosis noted 1 hour after the test item instillation in all animals and totally reversible between day 1 and day 2.
- at the corneal level: a slight opacity noted 24 hours after the test item instillation in one animal and totally reversible on day 2.
In conclusion, the results obtained, under these experimental conditions, enable to conclude that the test item STRONTIUM OXALATE does not have to be classified in accordance with the Regulation EC No. 1272/2008 on classification, labelling and packaging of substances and mixtures.
No symbol and warning label are required.
