On the cutaneous structure, it was noted a dryness between the 3rd and 6th day of the test in one animal, between the 4th and the 6th day in a second one and between the 4th and the 7th day in the last one. The skin recovered a normal aspect between the 7th and the 8th day of the test. - Other effects:

- Conclusions:
- Under the test conditions, test substance is not classified as irritating to skin according to the criteria of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
- Executive summary:
In a dermal irritation study performed according to the OECD Guideline No. 404, and in compliance with GLP, undiluted test substance was applied at the dose of 0.5 mL, under semiocclusive dressing during 4 hours on an undamaged skin area of 3 rabbits. On the opposite flank an untreated area was served as the control. Skin irritation was assessed and scored according to the Draize scale at 1, 24, 48, 72 h and Day 4 after the removal of the patch.
Twenty four hours after the test product application, it was noted, on the treated area, a slight to moderate erythema. These erythematous reactions were totally reversible between the 3rd and the 5th day of the test.
On the cutaneous structure, it was noted a dryness between the 3rd and 6th day of the test in one animal, between the 4th and the 6th day in a second one and between the 4th and the 7th day in the last one. The skin recovered a normal aspect between the 7th and the 8th day of the test.
The individual scores for each animal within 3 scoring times (24, 48 and 72 h) were 1.0 / 1.0 / 0.3 for erythema and 0.0 / 0.0 / 0.0 for oedema.
Under the test conditions, the test substance is not classified according to the criteria of the Regulation EC No. 1272/2008 (CLP) and to the GHS.
This study is considered as acceptable and satisfies the requirement for skin irritation endpoint.

- at the corneal level: a moderate opacity, registered 24 hours after the test product instillation, and totally reversible between the 5th and the 12th day of the test,
- at the iris level: a congestion, registered 24 hours after the test product instillation in 2 animals, and between the 5th and the 7th day of the test in one animal - Other effects:
- None
- Interpretation of results:
- Category 2A (irritating to eyes) based on GHS criteria
- Conclusions:
- Under the test conditions, the test substance is classified in Category 2 (H319: Causes serious eye irritation) according to the criteria of the Regulation EC No. 1272/2008 (CLP) and classified in Category 2A (irritating to eyes) according to the GHS.
- Executive summary:
In an eye irritation study conducted according to OECD 405 Guideline and in compliance with GLP, test substance was instilled as supplied, into the eye of 3 New Zealand rabbits at the dose of 0.1 mL, the other eye remained untreated serving as control. The lids were then gently held together for about one second in order to prevent loss of the test substance. The eyes were examined and the changes were observed at 1, 24, 48 and 72 h and 4 to 11 days after treatment and graded according to the Draize method.
The ocular reactions observed during the study have been slight to moderate, and totally reversible in the three animals:
- at the conjunctivae level: a moderate enanthema, noted 24 hours after the test product instillation and totally reversible between the 7th and the 9th day of the test, associated with a slight to moderate chemosis, noted 24 hours after the test product instillation and totally reversible between the 3rd and the 8th day of the test ;
- at the corneal level: a moderate opacity, registered 24 hours after the test product instillation, and totally reversible between the 5th and the 12th day of the test,
- at the iris level: a congestion, registered 24 hours after the test product instillation in 2 animals, and between the 5th and the 7th day of the test in one animal.
Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 2.0, 1.7, 1.3 for cornea score; 0.3, 0.3, 0.0 for iris score; 1.3, 2.0, 1.3 for conjunctivae score and 1.0, 1.3, 0.3 for chemosis score.
Under the test conditions, the test substance is classified in Category 2 (H319: Causes serious eye irritation) according to the criteria of the Regulation EC No. 1272/2008 (CLP) and classified in Category 2A (irritating to eyes) according to the GHS.
This study is considered as acceptable and satisfies the requirement for eye irritation endpoint.

Additional information
Skin irritation:
A key study was identified (Phycher, 2005). In this dermal irritation study performed according to the OECD Guideline No. 404, and in compliance with GLP, 3 male New Zealand White rabbits were exposed for 4 hours to a semi-occluded application of 0.5 mL of undiluted test material to the intact skin. Initially, a single animal was treated. After consideration of the cutaneous responses produced in the first treated animal, two additional animals were treated.
The individual scores for each animal within 3 scoring times (24, 48 and 72 h) were 1.0 / 1.0 / 0.3 for erythema and 0.0 / 0.0 / 0.0 for oedema. The substance is therefore not classified for skin irritation.
Eye irritation:
A key study was identified (Phycher, 2005). In this eye irritation study performed according to the OECD guideline 405, and in compliance with GLP, 0.1 mL of undiluted test material was instilled into one eye of 3 female New Zealand White rabbits. The other eye remained untreated and served as control. The lids were then gently held together for about one second in order to prevent loss of the test substance. The eyes were examined and the changes were observed at 1, 24, 48 and 72 h and 4 to 11 days after treatment and graded according to the Draize method.
Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 2.0, 1.7, 1.3 for cornea score; 0.3, 0.3, 0.0 for iris score; 1.3, 2.0, 1.3 for conjunctivae score and 1.0, 1.3, 0.3 for chemosis score.
The effects observed were all reversible within 11 days. The substance is therefore classified as eye irritating.
Justification for classification or non-classification
Harmonized classification:
The substance has no harmonized classification according to the Regulation (EC) No. 1272/2008 (CLP).
Self classification:
Based on the available data:
- no additional self-classification is proposed regarding skin irritation according to the CLP and to the GHS.
- the substance is classified in Category 2 (H319: Causes serious eye irritation) according to the CLP and classified in Category 2A (irritating to eyes) according to the GHS.
- No data was available regarding respiratory irritation.
