SCORING SYSTEM:
- Method of calculation: The respective scores for erythema and oedema formation for the 3 readings 24, 48 and 72 hours of each rabbit were summed up separately and divided by 6. The results are the mean scores for erythema and oedema formation of the individual rabbit.

Interpretation of results:
Category 2 (irritant)
Conclusions:
Based on the results of a study according to OECD Test Guideline 404 under GLP, the test substance is considered as skin irritating (applying the evaluation system of the EU regulation 1272/2008).
Executive summary:

The skin irritation potential of the test substance was evaluated in a study according to OECD Test Guideline 404 under GLP.

The amount of 0.5 ml of the substance was applied unchanged under semi-occlusive conditions for 4 hours to the clipped skin of three Mol:Russian rabbits, which were observed for 21 days post application. Over the first three days, clear erythema and oedema were observed in all rabbits, which reversed fully within 21 days.

Interpreting these results by applying the evaluation system of the EU regulation 1272/2008, the test substance is considered irritating to the skin.

Interpretation of results:
Category 1 (irreversible effects on the eye)
Conclusions:
Based on the results of a study according to OECD Test Guideline 405, the test substance is considered as severly irritating to the eye (applying the evaluation system of the EU regulation 1272/2008).
Executive summary:

The eye irritation potential of the test substance was evaluated in a study according to OECD Test Guideline 405.

The amount of 0.1 ml of the substance was applied unchanged for 24 hours to the eyes of six New Zealand White rabbits, which were observed for 7 days post application. Over the first three days, clear effects (cornea, iris, conjunctivae and chemosis) were observed, which did not fully reverse within 7 days.

Interpreting these results by applying the evaluation system of the EU regulation 1272/2008, the test substance is considered as severely eye irritating as at the end of the observation period effects still persisted.

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (irreversible damage)

Respiratory irritation

Endpoint conclusion
Endpoint conclusion:
no study available

Additional information

An in vitro study according to OECD test guideline 431 showed that the test substance is not skin corrosive. This complements the results of an in vivo study according to OECD Test Guideline 404, in which clear, but reversible (after 21 days) erythema and oedema were observed, but no corrosive effects.

Eye irritation was assessed in vivo according to OECD Test Guideline 405. Adverse effects on iris, cornea and conjunctivae were observed, which had not fully reversed at the end of the observation period, i.e. day 7. It remains unknown, if these effects would have reversed within 21 days.

Justification for classification or non-classification

Skin irritation/corrosion:

Interpreting the results of both the in vitro and in vivo test by applying the evaluation system of the EU regulation 1272/2008, the test substance is considered irritating to the skin.

Eye irritation:

Interpreting these results the results of the in vivo test by applying the evaluation system of the EU regulation 1272/2008, the test substance is considered as corrosive to the eye, because the study was terminated at observation day 7, although effects still persisted.
