Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions employed, Novozym 230 was regarded as negative as to potential for eye injury, and cannot be classified under the GHS criteria.
- Executive summary:
An eye irritation test on 6 albino rabbits carried out with Novozym 230 (batch PPZ1281) according to the Code of Federal Regulations, title 16, § 1500.42.
0.06 g of the test substance corresponding to the volume 0.1 mL was placed in the left eye of each rabbit by gently pulling the lower lid away from the eye ball, and the test substance was carefully introduced into
the resulting cup. The lids were then gently held together for one second. The right eye, remaining untreated, served as a control.
The treatments resulted in slight conjunctival redness in two of the rabbits until 24 hours. This effect was reversible within 48 hours.
Under the test conditions employed, Novozym 230 was regarded as negative as to potential for eye injury.
