Test system

Vehicle:
unchanged (no vehicle)
Amount / concentration applied:
53.1 ± 0.9 mg
Observation period (in vivo):
7 days
Number of animals or in vitro replicates:
3
Details on study design:
METHOD:
Each animal was treated by instillation of 53.1 ± 0.9 mg of the test substance (a volume of approximately 0.1 ml) in the conjunctival sac of one of the eyes after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of the test substance. The other eye remained untreated and served as the reference control.
Immediately after the 24 hour observation, a solution of 2% fluorescein in water (adjusted to pH 7.0) was instilled into both eyes of each animal to quantitatively determine corneal epithelial damage. Any bright green stained area, indicating epithelial damage, was estimated as a percentage of the total corneal area.

REMOVAL OF TEST SUBSTANCE

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
An eye irritation/corrosion study with SPS-100 in male rabbits was conducted according to OECD 405 and in accordance GLP guidelines. SPS-100 does not have to be classified and has no obligatory labelling requirement for eye irritation.
Executive summary:

An eye irritation/corrosion study with SPS-100 in male rabbits was conducted according to OECD 405 and in accordance with GLP guidelines. Single samples of approximately 53 mg of SPS-100 (a volume of approximately 0.1 ml) were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours and 7 days after instillation. Instillation of the test substance resulted in irritation of the conjunctivae, which was seen as redness, chemosis and discharge. The irritation had completely resolved within 48 hours in two animals and within 7 days in the other animal. Based on the results,SPS-100 does not have to be classified and has no obligatory labelling requirement for eye irritation.
