Interpretation of results:

GHS criteria not met

Conclusions:

No systemic effects were observed. Very slight erythema was observed following treatment which had resolved within 24 hours. The observed irritation was not of sufficient severity or duration for the substance to require classification as a skin irritant.

Executive summary:

Dermal irritation following a 4 hour exposure period has been assessed in accordance with OECD/EU test methods.

No systemic effects were observed. Very slight erythema was observed following treatment which had resolved within 24 hours. The observed irritation was not of sufficient severity or duration for the substance to require classification as a skin irritant.

Irritant / corrosive response data:

Response was assessed in a single animal. Well defined conjunctival chemosis and moderate redness were observed 1, 24 and 48 hours post-exposure. Seventy-two hours after exposure, slight chemosis and severe redness were observed. Slight redness was still observed after 7 and 14 days. Slight discharge and chemosis were noted after 14 days after dosing. Slight corneal opacity with the area of cornea involved greater than half was observed from 1 hour post-exposure up to the end of the observation period (21 days after treatment). The extension of the opacity gradually decreased from 48 hour post-exposure.

Conclusions:

Acute eye irritation has been investigated in the rabbit using methods in accordance with OECD/EU test guidelines. Significant irritation was observed that had not resolved within 21 days.

Executive summary:

Acute eye irritation has been investigated in the rabbit using methods in accordance with OECD/EU test guidelines. Significant irritation was observed that had not resolved within 21 days.

Endpoint conclusion

Endpoint conclusion:

no study available

Additional information

Acute dermal irritation has been assessed in the rabbit using OECD/EU test methods. The irritation observed was not of sufficient severity or persistence for the substance to require classification as a skin irritant.

Acute eye irritation has been assessed in the rabbit using OECD/EU test methods. The severity and persistence of ocular response was sufficient for the substance to require classification as an eye irritant.

Justification for classification or non-classification

Skin:

Based on the results of the available data the substance does not require to be classified and labelled according to Regulation 1272/2008/EC (CLP) or Directive 67/548/EEC (DSD).

Eyes:

The information available is regarded as sufficient to be able to draw conclusions regarding the need for classification. Classification as serious eye damage Category 1 - H318 according to CLP (1272/2008/EC) and risk of serious damage to eyes - R41 according to 67/548/EEC is indicated.
