Mean values over 24 h, 48 h and 72 h:

Animal 1: Opacity: 1; Iritis: 0; Erytema: 0; Chemosis: 0;

Animal 2: Opacity: 0,6; Iritis: 0; Erytema: 0; Chemosis: 0;

The application of the test substance caused slight to moderate corneal opacity up to 48 h, and slight to moderate erythema up to 3 h post treatment. All effects were fully reversible within 72 h.

The original BASF grading was converted into the numerical grading according to the OECD Draize system.
