- Executive summary:
In a dermal irritation study performed according to the OECD Guideline No. 404, and in compliance with GLP, 0.5 mL of undiluted test item was applied on an undamaged skin area of the flank of 3 male New Zealand White rabbits. On the other flank an untreated area was served as the control. Test sites were covered with a semi-occlusive dressing for 4 h. Skin irritation was assessed and scored according to the Draize scale at 1, 24, 48 and 72 hours after removal of the patch and observations were continued from Days 7 to 14. Initially, a single animal was treated. After consideration of the cutaneous responses produced in the first treated animal, two additional animals were treated.
A moderate erythema associated with a slight to severe oedema was noted on the treated area of the animals 24 hours after the patch removal. The erythematous and oedematous reactions were totally reversible between days 7 and 14. Dryness was noted from days 3 and 7 and was totally reversible on day 14.
The mean scores for each animal within 3 scoring times (24, 48 and 72 h) were 3 / 3 / 3 for erythema and 3.3 / 2 / 2.3 for oedema.
Therefore, the test material is classified as irritating to the skin in category 2 according to the Annex I 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.

Additional information
Skin irritation:
A key study was identified (Phycher, 2013). In this dermal irritation study performed according to the OECD Guideline No. 404, and in compliance with GLP, 3 female New Zealand White rabbits were exposed for 4 hours to a semi-occluded application of 0.5 mL of undiluted test item was applied on an undamaged skin area of the flank of 3 male New Zealand White rabbits. On the other flank an untreated area was served as the control. Test sites were covered with a semi-occlusive dressing for 4 h. Skin irritation was assessed and scored according to the Draize scale at 1, 24, 48 and 72 hours after removal of the patch and observations were continued from Days 7 to 14. Initially, a single animal was treated. After consideration of the cutaneous responses produced in the first treated animal, two additional animals were treated.
A moderate erythema associated with a slight to severe oedema was noted on the treated area of the animals 24 hours after the patch removal. The erythematous and oedematous reactions were totally reversible between days 7 and 14. Dryness was noted from days 3 and 7 and was totally reversible on day 14.
The mean scores for each animal within 3 scoring times (24, 48 and 72 h) were 3 / 3 / 3 for erythema and 3.3 / 2 / 2.3 for oedema.
Eye irritation:
A key study was identified (Phycher, 2013). In this eye irritation study performed according to the OECD guideline 405, and in compliance with GLP,

The eyes were examined and the changes were observed at 1, 24, 48 and 72 h and from 7 to 21 days following treatment and graded according to the Draize method. Initially, a single animal was treated.After consideration of the responses produced on day 21 in the first animal, two additional animals were not treated.
At the conjunctivae level, an important redness was noted 1 hour after the test item instillation and totally reversible on day 21, associated with an important chemosis, noted 1 hour after the test item instillation and totally reversible on day 21. At the iris level, a congestion was noted 1 hour after the test item instillation and totally reversible on day 7. At the corneal level, a moderate corneal opacity was noted 1 hour after the test item instillation and remaining on the last day of the test (day 21) with an important intensity.
