- Executive summary:
In a dermal irritation study performed according to the OECD Guideline No. 404, and in compliance with GLP, 0.5 mL of the undiluted test material was applied on the clipped skin of the right flank area of three male New Zealand White rabbits. The test material was held in contact with the skin by means of a semi-occlusive dressing for 4 h. The untreated skin served as control. Cutaneous reactions were assessed and scored according to the Draize scale at 1, 24, 48 and 72 h after removal of the dressing and then daily until reversibility of cutaneous reactions (Day 10).
A well-defined erythema, in addition to a slight oedema, was observed on Day 1 in all the animals. A well-defined erythema persisted in 1/3 animals from Day 2-6; a very slight erythema was then noted until Day 9. A very slight oedema was also observed on Day 2. In both remaining animals, a very slight erythema was recorded from Day 2-6. A dryness of the skin was observed in all the animals from Day 4 (two animals) or 7, to Day 9. Crusts were also noted in 1/3 animals on Days 5 and 6.
The individual scores for each animal within 3 scoring times (24, 48 and 72 h) were 2.0 / 1.0 / 1.0 for erythema and 0.3 / 0.0 / 0.0 for oedema.
Under the test conditions, test material is not classified as irritant to the skin according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP).
This study is considered as acceptable and satisfies the requirement for skin irritation endpoint.

- Under the test conditions, the test material induced slight irritation being reversible within 2 days. Therefore, the test material is not classified as irritant to the eyes according to the Annex VI of the Regulation (EC) No. 1272/2008.
- Executive summary:
In an eye irritation study, 0.1 mL of undiluted test material was instilled into the one eye of 6 albino rabbits while the contralateral eye remained untreated and served as control. The eyes were not rinsed after the instillation of test material. Animals were observed at 24, 48 and 72 after instillation of test material into eyes. The reactions in the conjunctivae (redness, chemosis and discharge), the iris and the cornea (opacity and area involved) were scored according to the Draize Scale.
The calculated mean score for each animal within 3 scoring times (24, 48 and 72 h) were 0.33/0.33/0.33/0.33/0.00/0.33 for redness, 0.00/0.00/0.00/0.33/0.00/0.33 for chemosis, and 0/0/0/0/0/0 for iris lesions and corneal opacity. The conjunctival reactions were fully reversible within 2 days.
Under the test conditions, the test material is not classified as irritating to the eyes according to the annex VI of the Regulation EC No. 1272/2008 (CLP).
This study is considered as acceptable and satisfies the requirement for eye irritation endpoint.

Additional information
Skin irritation:
A key study was identified (CIT, 2001, K1). This dermal irritation study was performed according to the OECD Guideline No. 404, and in compliance with GLP.
A well-defined erythema, in addition to a slight oedema, was observed on Day 1 in all the animals. A well-defined erythema persisted in 1/3 animals from Day 2-6; a very slight erythema was then noted until Day 9. A very slight oedema was also observed on Day 2. In both remaining animals, a very slight erythema was recorded from Day 2-6. A dryness of the skin was observed in all the animals from Day 4 (two animals) or 7, to Day 9. Crusts were also noted in 1/3 animals on Days 5 and 6.
The individual scores for each animal within 3 scoring times (24, 48 and 72 h) were 2.0 / 1.0 / 1.0 for erythema and 0.3 / 0.0 / 0.0 for oedema.
The registered substance is therefore not classified for skin irritation.
Eye irritation:
A key study was identified (Consumer Product Testing, 1979, rel.2). This eye irritation study was conducted similarly to OECD Guideline No. 405, with one deviation (6 animals tested instead of 3) that does not affect the reliability of the study.
The calculated mean score for each animal within 3 scoring times (24, 48 and 72 h) were 0.33/0.33/0.33/0.33/0.00/0.33 for redness, 0.00/0.00/0.00/0.33/0.00/0.33 for chemosis, and 0/0/0/0/0/0 for iris lesions and corneal opacity. The conjunctival reactions were fully reversible within 2 days.
The registered substance is therefore not classified for eye irritation.
Justification for selection of skin irritation / corrosion endpoint:
Only one study available, GLP-compliant and of high quality (Klimisch score = 1).
Justification for selection of eye irritation endpoint:
The key study performed on the registered substance in rats was pre-guideline and pre-GLP, but was performed similarly to OECD Guideline No. 405. This study was considered sufficiently robust to cover this endpoint.
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 both skin and eye irritation according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP).
No data was available regarding respiratory irritation, however the substance not being classified for skin and eye irritation, no classification is expected for respiratory irritation.
