Test animals / tissue source

Species:

rabbit

Strain:

New Zealand White

Details on test animals or tissues and environmental conditions:

Source: Harlan, Horst, The Netherlands
Number of animals: 3 males
Age and body weight: animals used within the study were at least 6 weeks old and body weights were at least 1.0 kg
Identification: ear mark
Health inspection: A health inspection was performed prior to commencement of treatment, to ensure that the animals were in a good state of health. Special attention was paid to the eyes, which were free from any abnormality

Test system

Amount / concentration applied:

Single samples of approximately 41 mg of SXJUL2006 (a volume of approximately 0.1 ml) were instilled into one eye of each of three rabbits.

Observation period (in vivo):

Observations were made 1, 24, 48 and 72 hours after instillation

Number of animals or in vitro replicates:

3

Details on study design:

The study was performed in a stepwise manner and was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner 5 weeks later, after considering the degree of eye irritation observed in the first animal.

Results and discussion

In vivo

Results

Results 1

Irritation parameter:

other: Irritation

Remarks on result:

other: No iridial or corneal opacity were observed, and treatment of the eyes with 2% fluorescin, 24 hours after test substance instillation revealed no corneal epithelial damage.

Results 2

Irritation parameter:

other: Corrosion

Remarks on result:

other: There was no evidence of ocular corrosion

Results 3

Irritation parameter:

other: Colouration/Remnants

Remarks on result:

other: Remnants of the test substance were present on the outside of the eyelids between days 1 and 3. Purple staining of the fur on the head and paws was noted during observation period. No staining of (peri) ocular tissues by the test substance was observed.

Results 4

Irritation parameter:

other: Toxicity / Mortality

Remarks on result:

other: No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occured.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Based on these results SXJUL2006 does not have to be classified and has no obligatory labelling requirement for eye irritation according to Globally Harmonized System of Classification and Labelling of Chemical (GHS) of the United Nations (New York and Geneva, 2003) and EC criteria for classification and labelling requirements for dangerous substances and preparations (Council Directive 67/548/EEC)
