New Zealand White
Details on test animals or tissues and environmental conditions:
Rabbits
Three female albino New Zealand rabbits were supplied by the Elevage de Gárome (Quartier Labaste — F40260 Linxe). They were kept during a minimal 5-day acclimatisation period. During the test, the animals weighed between 2.36 kg and 2.79 kg. At the beginning of the test, these animals were 12 weeks old. They were identified prior to inclusion in the test by means of numbered rings on the edges of their ears.

Housing
Each animal was kept in an individual box installed in conventional air conditioned animal husbanding:
The temperature and relative humidity of the main test were controlled to remain within target ranges of 17 to 23°C and 30 to 70%, respectively.
The rate of air exchange was approximately fifteen changes per hour and the lighting was controlled by a time switch to give twelve hours continuous light (07.00 to 19.00) and twelve hours darkness.

Food and drink
Drinking water (tap-water from public distribution system) and foodstuff (SDS - C15) were supplied freely.
Microbiological and chemical analyses of the water were carried out once every six months by IPL Sante Environnement Durables — Atlantique (Bordeaux).

Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
In a GLP-study according to OECD test guideline 405, the registered substance induced only slight conjuntivae responses, which reversed completely latest after 72h. Consequently, the substance is consdiered to be not irritating to the eye (according to regulation EC No 1272/2008)..
Executive summary:

The test substance 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 O.E.C.D. guideline No. 405.

The ocular conjunctivae reactions observed during the study have been slight to moderate and totally reversible in the three animals: a slight to moderate redness noted 1 hour after the test item instillation and totally reversible between days 1 and 3, associated with a slight chemosis noted 1 hour after the test item instillation and totally reversible between days 1 and 2.

In conclusion, the results obtained, under these experimental conditions, enable to conclude that the test substance 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. Directives 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.
