Description of key information

Skin irritation in vivo:

0.5 ml test item (50% test item 50% water) is applied to intact skin of 6 rabbits and scarificed skin of 6 rabbits (2.5 x 2.5 cm) for 24 h. Animals were observed for 14 days. Erythema and oedema were recorded according to Draize. No irritation (scores 0) was observed on the intact and scarificed skin at any time point.

Eye irritation in vivo:

100 mg test item was applied to the eye of a rabbit and animals were imnvestigated after 24, 48 and 72 h. Cornea, iris, conjunctivae and secretion observations were scored according to Draize. No effects (scores 0) were reported for all endpoints and all time points.

Additional information

Justification for classification or non-classification

No irritation (scores 0) were reported in early in vivo skin and eye irritation studies in rabbits. Classification is not warranted.
