Description of key information
Skin: The test item produced a primary irritation index of 0.7 and was considered to be a mild irritant to rabbit skin according to the Draize scheme. No corrosive effects were noted. However, the test material is not classified under the terms of Regulation (EC) No 1272/2008 (OECD 404 and EU Method B.4).
Eye: The test item produced a
maximum group mean score of 16.0 and was considered to be a moderate
irritant (Class 5 on a 1 to 8 scale) to the rabbit eye according to a
modified Kay and Calandra system. However, the test material is not
classified under the terms of Regulation (EC) No 1272/2008 (OECD 405 and
EU Method B.5).

- ANIMALS AND ANIMAL HUSBANDRY
- Three New Zealand White (Hsdlf:NZW) strain rabbits were supplied by Harlan Laboratories UK Ltd, Leicestershire UK.
- At the start of the study the animals weighed 2.51 to 2.92 kg and were 12 to 20 weeks old.
- After an acclimatisation period of at least 5 days, each animal was given a unique number within the study by writing with black indelible marker-pen on the inner surface of the ear and on the cage label.
- Animals were individually housed in suspended cages.
- Free access to mains drinking water and food (2930C Teklad Global Rabbit diet supplied by Harlan Laboratories Ltd, Oxon, UK) was allowed throughout the study.
- The diet and drinking water were considered not contain any contaminant of a level that might have affected the purpose or integrity of the study.
- Temperature and elative humidity were set to achieve limits of 17 °C to 23 °C and 30 % to 70 % respectively.
- The rate of air exchange was at least 15 changes per hour.
- Lighting was controlled by a time switch to give twelve hours continuous light (06:00 to 18:00) and twelve hours darkness.
- The animals were provided with environmental enrichment items, which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study. - Type of coverage:

- Details on study design:
- TEST ITEM FORMULATION
- The absorption of the test item was not determined.
MEASUREMENT OF pH
- The pH of the test item was determined prior to commencement of the study.
PROCEDURE
- On the day before the test, two rabbits were clipped free of fur from the dorsal/flank area using veterinary clippers.
- Only animals with a healthy intact epidermis by gross observation were selected for the study.
- On the day of the test, a suitable test site was selected on the back of each rabbit.
- A quantity (0.5 mL) of the test item was applied directly to the skin under a 2.5 cm x 2.5 cm cotton guaze patch.
- The patch was secured in position with a strip of surgical adhesive tape.
- To prevent the animals interferring with the patches, the trunk of each rabbit was wrapped in an elasticated corset and the animals were returned to their cages for the duration of the exposure period.
- Four hours after application, the corset and patches were removed from each animal and any residual test item removed by gentle swabbing with cotton wool soaked in distilled water.
- Immediately following removal of the patches, and approximately 1, 24, 48 and 72 hours later, the test sites were examined for evidence of primary irritation and scored according to defined criteria (see attached scale for evaluation of skin reactions).
- If present, any other skin reactions and clinical signs of toxicity were also recorded.
- Based on the results for the initial two animals, and at the request of the sponsor, a third animal was treated as described previously.
- An additional observation was made on the initial two treated animals on Day 7 to assess the reversibility of skin reactions.
- Individual body weights were recorded on Day 0 (the day of dosing) and at the end of the observation period. - Irritation parameter:

GUIDELINE
The irritancy potential of the test item to the skin of the New Zealand White rabbits was investigated using a procedure designed to be compatible with OECD Guideline for the Testing of Chemicals No 404 "Acute Dermal Irritation/Corrosion (adopted 24 April 2002) and Method B.4 Acute Toxicity (Skin Irritation) of Commission Regulation (EC) No 440/2008.
RESULTS
A single 4 hour, semi-occluded, application of the test item to the intact skin of three rabbits produced very slight to well-defined erythema and very slight edema at two treated skin sites. One treated skin site appeared normal at all observations, one other treated skin site appeared normal at the 24 hour observation and the remaining skin site appeared normal at the 7 day observation.
CONCLUSION
The test item produced a primary irritation index of 0.7 and was considered to be a mild irritant to rabbit skin according to the Draize scheme. No corrosive effects were noted.However, the test material is not classified under the terms of Regulation (EC) No 1272/2008 because the mean scores for three animals calculated using data from 24, 48 and 72 hour observations were below the stated limits for erythema and edema.

GUIDELINE
The study was performed to assess the irritancy potential of the test item to the eye of the New Zealand White rabbit using a procedure designed to be compatible with OECD Guideline for the Testing of Chemicals No 405 "Acute Eye Irritation/Corrosion" (adopted 02 October 2012) and EU Method B.5 Acute Toxicity (Eye Irritation) of Commission Regulation (EC) No 440/2008.
RESULTS
A single application of the test item to the non-irrigated eye of two rabbits produced iridial inflammation and moderate conjunctival irritation. Both eyes appeared normal at the 7 day observation.
CONCLUSION
The test item produced a maximum group mean score of 16.0 and was considered to be a moderate irritant (Class 5 on a 1 to 8 scale) to the rabbit eye according to a modified Kay and Calandra system. However, the test material is not classified under the terms of Regulation (EC) No 1272/2008 because the mean scores for two animals calculated using data from 24, 48 and 72 hour observations were below the stated limits for corneal opacity, iritis, conjunctival redness and chemosis.

CONCLUSION
The test item produced a maximum group mean score of 16.0 and was considered to be a moderate irritant (Class 5 on a 1 to 8 scale) to the rabbit eye according to a modified Kay and Calandra system. However, the test material is not classified under the terms of Regulation (EC) No 1272/2008 because the mean scores for two animals calculated using data from 24, 48 and 72 hour observations were below the stated limits for corneal opacity, iritis, conjunctival redness and chemosis.
Justification for classification or non-classification
Skin: In accordance with EU CLP Regulation (EC) No. 1272/2008, classification of this substance is not required for dermal irritation as the primary effects, erythema and edema, were reversed by the end of the observation period. In addition, the scores for erythema and edema did not fall within the range requiring classification.
Eye: In accordance with EU CLP Regulation (EC) No. 1272/2008, classification of this substance is not required for eye irritation because no corneal opacity was observed and iridial inflammation, conjunctival redness and chemosis were reversed by the end of the 7 day observation period. Furthermore, the mean scores for each of the parameters do not fall within the range requiring classification.
