Eye irritation

Administrative data

Endpoint:

eye irritation: in vitro / ex vivo

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is classified as skin corrosion, leading to classification as serious eye damage (Category 1)

Remarks:

Not scored due to eschar formation

Irritant / corrosive response data:

On 25% of the treated surface, black discolouration of the skin (a sign of necrosis) was present after 1 and 24 hours, resulting in eschar formation. A thick black scab was noted after 72 hours. Erythema score 4 was indcated for the aforementioned skin effects. Reactions seen in the remaining skin area (75%) resulted in erythema scores between well defined and moderate to severe erythema. Scoring of oedema was not possible after 48 and 72 hours due to eschar formation and/scab formation.

Other effects:

The animal was sacrified for humane reasons after 72 hours based on the severity of the skin effects, and no other animals treated.

No staining of the treated skin by the test substance was observed.

No symptoms of systemic toxicity were observed in the animal during the test period.

Interpretation of results:

Category 1 (corrosive) based on GHS criteria

Remarks:

Not possible to sub-categorise based on data available

Conclusions:

This substance is corrosive to skin under the conditions of the test.
