The test substance was slight to moderately irritating to the eye. According Directive 67/548 EEC a classification is not required - however according GHS a classification a Eye Irrit.2; H319 is justified based on a cornea score > 1and a conjunctiva score > 2.

Executive summary:

The lids were then gently held together for about one second. the other eye remained untreated and served as control. The treated eye was washed out with physiological NaCl solution 24 hours after instillation of the test compound.

The test substance was slight to moderately irritating to the eye. According Directive 67/548 EEC a classification is not required - however according GHS a classification as Eye Irrit.2; H319 is justified, based on a cornea score>1and a conjunctiva score>2.

Additional information

In the key-studyfor skin irritation/corrosion, three white New-Zealand rabbits were treated with 0.5 ml of undiluted test substance. The test item remained under semiocclusion on the skin for 4 hours. Treated animals were inspected for skin effects (erythma, oedema) after removal of patches and after 1, 2, 3 and 7 days. Total observation time was 7 days. For each animal the DRAIZE scores recorded approx. 24, 48, and 72 hours after application. An erythema score of 0.9 for erythema and 0.7 for edema were reported. Skin effects were fully reversible after 7 days and 72 hours, respectively.

In the key-study for eye irritation, 100 µl test compound was instilled into the conjunctival sac of one eye of each of 3 rabbits. The lids were then gently held together for about one second. the other eye remained untreated and served as control. The treated eye was washed out with physiological NaCl solution 24 hours after instillation of the test compound. The irritation scores / mean irritation scores were calculated for cornea, iris, erythema and swelling (chemosis) of the conjunctivae were calculated according to Draize at 24, 48 and 72 hours.

A cornea score > 1, an iris score = 0 was determined. The conjunctiva score was > and the chemosis was = 0.9. All effects were reversible within 14 or 7 days.

Justification for selection of skin irritation / corrosion endpoint:
The most reliable study was used as key study and for classification.

Justification for selection of eye irritation endpoint:
The most reliable study was used as key study and for classification.

Effects on eye irritation: irritating

Justification for classification or non-classification

m-chloroaniline was slightly irritating to the skin, but the measured score values were not sufficient for classification.

The test substance was slight to moderately irritating to the eye. According Directive 67/548 EEC a classification is not required - however according GHS a classification as Eye Irrit.2; H319 is justified, based on a cornea score>1and a conjunctiva score>2.
