Additional information
Skin Irritation
The key study was conducted in accordance with the standardised guideline OECD 404.
Six male New Zealand White rabbits were dermally exposed to 0.5 g of the test material moistened with 0.06 mL of water to form a paste. Test sites were covered with a semi-occlusive dressing for 4 hours, followed by observation of the animals for 72 hours. Irritation was evaluated based on erythema and oedema reactions observed 24, 48 and 72 hours after the end of application.
No skin reactions were observed during the study. The mean score for the readings at 24, 48 and 72 hours for both erythema and oedema was equal to 0.
Under the conditions of this study, the test material is not classified.
Supporting information is provided in the form of a second study that followed the FHSA 16 CFR 1500.41 guideline. This study was awarded a reliability score of 2 in accordance with the criteria of Klimisch (1997).
Six New Zealand White rabbits were dermally exposed to 0.5 g of the test material on one intact and one abraded skin site. Test sites were covered with an occlusive dressing for 24 hours. The patches were then removed and the test sites wiped to prevent further exposure. Evaluation occurred 24 and 72 hours after exposure.
With the exception of one intact site with very slight erythema at 24 hours, all sites were clear of irritation during the test period.
Under the conditions of this study, the test material is not irritating to skin and requires no classification.
Eye Irritation
The key eye irritation study was conducted in accordance with the standardised guideline OECD 405. 0.1 g of the test material was instilled into the conjunctival sac of the right eye of six male New Zealand white rabbits.
Ocular irritation was scored based on chemosis and changes to the iris, cornea and conjunctivae at 24, 48 and 72 h.
The mean scores for the 6 rabbits across all time points were 0 for corneal opacity, 0.06 for iritis, 0 for redness and 0.22 for chemosis of the conjunctivae.
In this study, the test material was seen to be not irritating to the eye, requiring no classification.
Supporting information is provided in the form of second study conducted in accordance with FHSA guideline 16 CFR 1500.42. This study was awarded a reliability score of 1 in accordance with the criteria of Klimisch (1997).
0.1 g of the test material was instilled into the right eye of six New Zealand white rabbits, with three of the treated eyes being rinsed after 30 seconds with saline. The animals were observed for three days and the eyes examined at 24, 48 and 72 hours. Irritation was scored according to the method of Draize.
The test material produced minimal irritation to both the unwashed and washed eyes and no classification is required under the conditions of this study.
Justification for selection of skin irritation / corrosion endpoint:
The key study was conducted in accordance with the standardised guideline OECD 404. It was well reported and adhered to sound scientific principles. It was awarded a reliability score of 1 in accordance with the criteria of Klimisch (1997).
Justification for selection of eye irritation endpoint:
The key study was conducted in accordance with the standardised guideline OECD 405. It was well reported and adhered to sound scientific principles. It was awarded a reliability score of 1 in accordance with the criteria of Klimisch (1997).
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the test material does not require classification for irritation or corrosion to either the skin or eye.
