SCORING SYSTEM: A modified Primary Irritation Index was calculated by adding the mean erythema and edema scores at the 60 minute after removal of wrappings, 24, 48 and 72 hour scoring intervals, and dividing by the number of evaluation intervals (4).
Erythema and Eschar
0: No erythema
1: Very slight erythema (barely perceptibe)
2: Well defined erythema
3: Moderate to severe erythema
4: Severe erythema (beet redness) to slight eschar formation (injuries in depth)
Oedema
0: No oedema
1: Very slight oedema (barely perceptible)
2: Slight oedema (edges of area well-defined by definite raising)
3: Moderate oedema (raised approximately 1.0 mm)
4: Severe oedema (raised more than 1.0 mm, extending beyond the area of exposure) - Irritation parameter:
- primary dermal irritation index (PDII)
- Basis:
- mean
- Time point:
- other: 72 hours
- Score:
- 0.25
- Reversibility:
- fully reversible within: 48 hours
- Irritant / corrosive response data:
- Erythema was absent to very slight at 60 minutes and 24 hours after patch removal and absent at 48 and 72 hours. There was no oedema noted at any observation period.
- Other effects:
- There were no abnormal physical signs noted during the observation period.
All body weight changes were normal. - Interpretation of results:
- other: Not classified in accordance with EU criteria
- Conclusions:
- A modified primary mean irritation score of 0.25 was determined in this study.
- Executive summary:
To determine the irritant or corrosive effects, if any, of the test substance when applied dermally, a study following OECD Guideline Number 404 was performed.
Since the test article was not expected to produce severe irritation or corrosion, three healthy New Zealand White rabbits (females) were dosed dermally with the test substance. The test article (0.5 mL) was applied dermally to one intact site/rabbit. The test article was kept in contact with the skin for 4 hours at which time the wrappings were removed. Dermal reactions were scored at 60 minutes after removal of wrappings. Reactions were scored again at 24, 48 and 72 hours. The skin was also evaluated for ulceration and necrosis or any evidence of tissue destruction at these time periods. Body weights were recorded pretest and at termination. A modified Primary Irritation Index was calculated using the 60 minute, 24, 48 and 72 hour scoring intervals.
Erythema was absent to very slight at 60 minutes and 24 hours after patch removal and absent at 48 and 72 hours. There was no oedema noted at any observation period.
There were no abnormal physical signs noted during the observation period. All body weight changes were normal.
The study authors concluded that the substance is not a dermal irritant.

- Executive summary:
To determine the irritant and/or corrosive effects, the test substance was instilled into the rabbit eye. This study was designed to follow OECD Guideline 405.
Three healthy New Zealand White rabbits (2 males - 1 female), free from evidence of ocular irritation and corneal abnormalities, were dosed with the test substance. The test article (0.1 mL) was placed into the conjunctival sac of one eye of each rabbit. The contralateral eye served as control. The treated and untreated eye of each rabbit were examined and scored by the Draize technique at 1, 24, 48 and 72 hours postdose. Both eyes were washed with saline following the 24 hour observation interval for approximately one minute using a volume and velocity of flow which did not cause injury. The eye irritation score for each rabbit was calculated each day. Body weights were recorded pretest and at termination.
Treated Eyes: There was no corneal opacity or iritis noted at any observation period. Conjunctival irritation, noted in 3/3 eyes, cleared by 48 hours.
Control Eyes: All three control eyes appeared normal at each observation period.
There were no abnormal physical signs noted during the observation period.
Ocular administration of the test substance produced conjunctival irritation which cleared by 48 hours.

Additional information
To determine the irritation or corrosive potential of the test substance in eyes and skin of rabbits, studies were performed according to OECD 404 and 405. Dermal reactions were scored and a modified Primary Irritation Index was calculated using the 60 minute, 24, 48 and 72 hour scoring intervals. The eyes were examined and scored by the Draize technique at 1, 24, 48 and 72 hours post dose.
Erythema was absent to very slight at 60 minutes and 24 hours after patch removal and absent at 48 hours and 72 hours in the dermal irritation study in rabbits. There were no abnormal physical signs noted during the observation period.
In treated rabbit eyes, there was no corneal opacity or iritis noted at any observation period. Conjunctival irritation, noted in 3/3 eyes, cleared by 48 hours. There were no abnormal physical signs noted during the observation period.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to skin and eye irritation/corrosion.
