Any other information on results incl. tables

Signs of irritation/corrosion were irreversible in all rabbits can be summarized as follows:

- suppuration

- loss of hair at mrgines of eyelids

- discharge of blood

- loss of corneal tissue

Due to these symptoms, the study was ended 72 h after application.

Applicant's summary and conclusion

Interpretation of results:
Category 1 (irreversible effects on the eye)
Remarks:
Migrated information
Conclusions:
Under the test conditions chosen and considering the described findings ASTA-C15-Salz krist. has the potential to cause severe eye damage. Thus, the test substance needs to be classified according to Regulation (EC) No. 1272/2008.
