Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- In conclusion, the results obtained, under these experimental conditions, enable to conclude that the test item reaction mass of DIPE and 2-methylpent-2-ene does not have to be classified according to the criteria for the classification, packaging and labelling of dangerous substances in
compliance with the E.E.C. Directive n° 67/548, 2001/59 and 99/45. No symbol or warning label is required.
In accordance with Regulation EC No 1272/2008, the test item does not have to be classified. No signal word or hazard statement is required. - Executive summary:
Acute eye irritation was assessed for reaction mass of DIPE and 2-methylpent-2-ene according to OECD guideline No 405. The test item was instilled as supplied, into the eye of 3 New Zealand rabbits at the dose of 0.1 mL. The experimental protocol was established on the basis of the official method as defined in the OECD guideline No 405 dated April 24th, 2002 and the test method B.5 of the Council regulation No 440/2008.
The ocular reactions observed during the study have been moderate and totally reversible in the three animals:
- at the conjunctivae level: a moderate redness noted 1 hour after the test item instillation and totally reversible between days 3 and 8, associated with a moderate chemosis noted 1 hour after the test item instillation and totally reversible between days 3 and 4,
- at the corneal level: a moderate corneal opacity, noted 24 hours after the test item instillation, in two animals and totally reversible on day 2.
In conclusion, the results obtained, under these experimental conditions, enable to conclude that the test item reaction mass of DIPE and 2-methylpent-2-ene does not have to be classified according to the criteria for the classification, packaging and labelling of dangerous substances in compliance with the E.E.C. Directive n° 67/548, 2001/59 and 99/45. No symbol or warning label is required.
In accordance with Regulation EC No 1272/2008, the test item does not have to be classified. No signal word or hazard statement is required.
