Additional information

Skin irritation

The test substance was assessed for skin irritation according to EU Method B4. 

No irritation was observed after a 4 hour exposure in any animal, at any time point and all scores for erythema and edema were 0 after

72 hours.No signs of toxicity were noted either.

The substance is not a skin irritant.

Eye irritation

The test substance was assessed for eye irritation according to EU Method B5. 

No chemosis, corneal or iridial effects were noted during the study. Minimal conjunctival irritation (redness, score of 1) was observed in animals after 1 hour. These effects were fully reversible within 1 day.

The substance is not an eye irritant.


Justification for selection of skin irritation / corrosion endpoint:
Study data over 12 years old provided by ECHA, on a previously notified substance considered comparable and suitable for use for the substance being registered.
Study conducted in accordance with generally accepted scientific principles and guidelines.

Justification for selection of eye irritation endpoint:
Study data over 12 years old provided by ECHA, on a previously notified substance considered comparable and suitable for use for the substance being registered.
Study conducted in accordance with generally accepted scientific principles and guidelines.

Justification for classification or non-classification

The results from skin irritation and eye irritation studies were evaluated according to the Classification, Labelling and Packaging Regulation (EC) 1272/2008 (CLP).

Skin irritation:

No skin irritation was caused by 4 hours exposure to the test substance. Based on these results, the substance does not have to be classified as a skin irritant as it does not meet the criteria for classification according to the Classification, Labelling and Packaging Regulation (CLP).

Eye irritation:

No chemosis, corneal or iridial effects were noted during the study. Minimal conjunctival irritation (redness, score of 1) was observed in animals after 1 hour. These effects were fully reversible within 1 day.

The overall results calculated on the basis of the scores for each animals at 24, 48 and 72 hours did not meet the criteria for classification according to the Classification, Labelling and Packaging Regulation (CLP). The test substance is therefore not classified for eye irritation.
