Applicant's summary and conclusion

Interpretation of results:
study cannot be used for classification
Conclusions:
In the eyes of rabbits, maleic acid caused permanent corneal opacity and vascularization at a concentration of 10% (pH= 1.0) after 30 seconds, and transient corneal cloudiness at a concentration of 1 % (pH = 1.0) after 2 minutes.
