- Remarks:
- Study performed according to US-FHSA guideline. Deviations from standard method: no data on test animals, 24 h exposure instead of 4h, occlusive dressing instead of semi-occlusive, observation at 24 and 72 h only (no 48h scoring), reversibility not assessed during a 14-day observation period. However, since only minimal responses persisted until the 72-h time point (maximum score = 1), the study results can be used for classification purpose (Ref: CLP Guidance). A new study is unlikely to show worse effects; therefore, this study was considered sufficiently robust to cover this endpoint.

- Executive summary:
In a dermal irritation study performed according to US-FHSA guideline, 0.5 g of undiluted test material was dermally applied on the intact side surface of 6 albino rabbits. Test sites were covered with an occlusive dressing for 24 h. Skin irritation was assessed and scored according to the Draize scale at 24 and 72 h after the removal of the patch.
Under the test conditions, the test material induced slight erythema and oedema. Although reversibility was not assessed, responses were minimal at the 72 -hour time points. According to the CLP Guidance, it is therefore possible to use this study for classification by calculating the mean values for erythema and oedema on the basis of 24 and 72 -h time points.
The individual scores for each animal within 2 scoring times (24 and 72 hours) were 1 / 1 / 1 / 1 / 1 / 0.5 for erythema and 0.5 / 0.5 / 0.5 / 0.5 / 0.5 / 0 for oedema.
Therefore, the test material is not classified as irritant to the skin according to the Annex VI of the Regulation (EC) No. 1272/2008.

- Executive summary:
In an eye irritation study performed similarly to OECD guideline No. 405, 0.1 g of undiluted test material was instilled into the right eye of 6 albino rabbits while the left eye remained untreated and served as control. Test material was not washed from the eyes. Animals were observed at 24, 48 and 72 h after instillation of test material into eyes and then on Days 5 and 7. The reactions in the conjunctivae (redness, chemosis and discharge), the iris and the cornea (opacity and area involved) were scored according to the “Illustrated guide for grading eye irritation by hazardous substances”.
The calculated mean score for each animal within 3 scoring times (24, 48 and 72 h) were 2.00 / 2.00 / 2.00 / 2.67 / 2.00 / 2.00 for redness, 3.33 / 4.00 / 1.67 / 2.67 / 2.33 / 2.67 for chemosis, 1.00 / 1.00 / 1.00 / 1.33 / 1.67 / 1.67 for iris lesions and 2.00 / 2.00 / 1.00 / 1.00 / 1.67 / 2.00 for corneal opacity.
Those scores do not allow to classify the substance for serious eye damage (0/6 rabbits show a mean score per animal of ≥ 3 for corneal opacity and 2/6 animals show a mean score per animal of > 1.5 for iritis). Animals showed corneal and conjunctival reactions (redness, chemosis and discharge) which were not fully reversible within 7 days but the observation period was only 7 days instead of 21 days in current in vivo studies and a beginning of recovery was observed and, based on an expert judgment, a full reversion can be expected within an observation period of 21 days. Therefore, based on the effects observed and the measured scores, the substance is a severe eye irritant.
Under the test conditions, the test material has a classification of Category 2 (H319: Causes serious eye irritation) according to the Regulation (EC) No. 1272/2008 (CLP).

Additional information
Skin irritation:
A key study was identified (Biosearch, 1979, rel.2). This dermal irritation study was performed according to US-FHSA guideline. Deviations from standard OECD method are as follow: 24 h exposure instead of 4h, occlusive dressing instead of semi-occlusive dressing, observation at 24 and 72 h only (no 48h scoring), reversibility not assessed during a 14-day observation period. However, since only minimal responses persisted until the 72 -h time point (maximum score = 1), the study results can be used for classification purpose (Ref: CLP Guidance). A new study is unlikely to show worse effects; therefore this study was considered sufficiently robust to cover this endpoint.
Under the test conditions, the test material induced slight erythema and oedema.
The individual scores for each animal within 2 scoring times (24 and 72 hours) were 1 / 1 / 1 / 1 / 1 / 0.5 for erythema and 0.5 / 0.5 / 0.5 / 0.5 / 0.5 / 0 for oedema.
Therefore, the test material is not classified as irritant to the skin.
Eye irritation:
A key study was identified (Biosearch, 1979, rel.2). In this eye irritation study conducted similarly to OECD Guideline No. 405, 0.1 mL of undiluted test material was instilled into the conjunctival sac of one eye of 6 New Zealand White rabbits while the remained untreated eye served as control. The eyes were not rinsed after the instillation of test material. Animals were observed at 24, 48 and 72 h after instillation of test material into eyes and then on Days 5 and 7. The calculated mean score for each animal within 3 scoring times (24, 48 and 72 h) were 2.00 / 2.00 / 2.00 / 2.67 / 2.00 / 2.00 for redness, 3.33 / 4.00 / 1.67 / 2.67 / 2.33 / 2.67 for chemosis, 1.00 / 1.00 / 1.00 / 1.33 / 1.67 / 1.67 for iris lesions and 2.00 / 2.00 / 1.00 / 1.00 / 1.67 / 2.00 for corneal opacity. Those scores do not allow to classify the substance for serious eye damage (0/6 rabbits show a mean score per animal of ≥ 3 for corneal opacity and 2/6 animals show a mean score per animal of > 1.5 for iritis). Animals showed corneal and conjunctival reactions (redness, chemosis and discharge) which were not fully reversible within 7 days but the observation period was only 7 days instead of 21 days in current in vivo studies and a beginning of recovery was observed and, based on an expert judgment, a full reversion can be expected within an observation period of 21 days. Therefore, based on the effects observed and the measured scores, the substance is a severe eye irritant.Justification for selection of skin irritation / corrosion endpoint:
Only one study available (US-FHSA, non-GLP, Klimisch score=2)
Justification for selection of eye irritation endpoint:
Only one study available (US-FHSA, non-GLP, Klimisch score=2)
Effects on eye irritation: highly irritating
Justification for classification or non-classification
Harmonized classification:
The substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.
Self classification:
Based on the available data no additional self-classification is proposed regarding skin irritation according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP).
Based on the available data the test material is classified as "Category 2: Causes serious eye irritation" according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP).
No data was available regarding respiratory irritation.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
