Executive summary:

The irritation potential of Reactive Red 180 was tested in the flank skin of 6 rabbits with shaved and abraded skin. No signs of skin irritation were noted either in shaved or in abraded skin with 500 mg undiluted test substance.

Consequently, the test substance is not irritating to skin.

Details on study design:
The test item was applied to the left eye of each rabbit. The contra-lateral eye surved as intra-individual control. Evaluation 1, 7, 24, 48, and 72 hours after test item application by means of a magnifying lens. After 24 hours the eyes were rinsed with physiological saline solution. At 48 and 72 hours evaluation, fluorescein staining was used to verify the absence of corneal lesions.

Additional information

Skin irritation / Corrosion

The test item was tested for skin irritation properties. The evaluation of the erythema and edema scores at the 24, 48, and 72 hour time points showed that the test item is not irritating to skin according to CLP/FDA evaluation schemes.

Eye irritation

The effects on rabbit eyes observed up to 72 hours (chemosis and/or reddening) do not result in any classification. The test item, applied to rabbit eye mucosa, caused conjunctival irritant effects at seven hours, which were reduced at 24 hours after application. Slight corneal opacity were observed at 7 and 24 hours in one out of six animals. All conjunctival irritation effects were completely reversed at the 72 hours observation period. Some slight discolouration of the conjuctivae remained at the observation period of 72 hours, but this is not considered as a classifiable effect under the CLP/FDA Regulation.

Respiratory irritation

Respiratory irritation was not assessed; however no effects on the animals were noted in any associated studies.

Justification for classification or non-classification

The above studies have all been ranked reliability 1 or 2 according to the Klimisch et al system. This ranking was deemed appropriate because the studies were conducted in compliance with agreed protocols.

The above results triggered no classification under the Dangerous Substance Directive (67/548/EEC) and the CLP Regulation (EC No 1272/2008).
