Results

Irritation parameter:

maximum mean total score (MMTS)

Basis:

animal: All rabbits (65967, 66032 and 66033 males)

Time point:

other: 1, 24, 48, 72 hours and 7 days

Score:

ca. 10

Reversibility:

fully reversible

Irritant / corrosive response data:

The test material produced moderate conjunctival irritation. Dark red-coloured staining of the lower conjunctival and nictitating membranes and red-coloured staining of the fur around the treated eye were also noted. One treated eye appeared normal at the 72-hour observation and the two remaining treated eyes appeared normal atthe 7-day observation

Applicant's summary and conclusion

Interpretation of results:

not irritating

Remarks:

Migrated informationCriteria used for interpretation of results: EU

Conclusions:

Classification: MILD IRRITANT (CLASS 4 ON A 1-8 SCALE)The test material did not meet the criteria for classification as irritant according to EU labelling regulations Commission Directive 2001/59/EC.

Executive summary:

A study was performed to assess the irritation of the test material to the eye of the New Zealand White rabbit (SPL Standard Test Method 560.09), The method followed OECD Guidelines for Testing of Chemicals (24 April 2002) No. 405 "Acute Eye Initation/Corrosion" and Method B5 of Commission Directive 2004/73/EC (which constitutes Annex V of Council Directive 67/548/EEC).

Classification: MILD IRRITANT (CLASS 4 ON A 1-8 SCALE). The test material did not meet the criteria for classification as irritant according to EU labelling regulations Commission Directive 2001/59/EC
