- adverse effect observed (irreversible damage)
Additional information
Both studies were considered when determining the skin corrosion/irritation endpoint of the test material. However, the Key study was used for Classifiaction purposes in accordance with the criteria set in the CLP guidiance document.
The study for eye damage was used for classification of the test material in accordance with the criteria set in the CLP document
Justification for classification or non-classification
Data from available for two in vivo skin corrosion studies were used for skin corrosion hazard assessment for the Test substance and the studies were conducted in accordance with a guideline comparable to OECD 404. Mallory, 1986, studies concluded that the test substance is corrosive based on the CLP criteria. Test substance was exposed to rabbits skin for 4hours. After exposure time substance was completely wiped off and animals were observed for 30 -60minutes, 24hrs, 48hrs , 72hrs and daily for 14days. Necrosis, fissuring and sloughing were observed on rabbits throughout the study. Edema mean score for 24, 48 and 72hrs was 2 and fully reversible effect was seen within 11days furthermore, erythema mean score for 24, 48 and 72hrs was 3.5 with no reversible effect was observed for 14 days observation period. In the second study, a supporting study, Mallory , 1982, study concluded that the test material was corrosive based on the CLP criteria. Rabbits skin abraded and intact were exposed to test material for 24hrs and observed at 24hrs, 72hrs and daily for 13days. Slight to well defined erythema was observed at 24hrs, 72hrs and on day 4 through day 12 similarly, slight to moderate edema was observed at 24hrs, 72hrs and on day 4 through day 12. Therefore, based on the conclusion drawn from Mallory, 1986 study, slight to severe erythema was observed at 30mins-60mins and throughout study with observation period of 14days, with evidence of necrosis fissuring and sloughing observed, the Test substance will therefore be classified as a Corrosive to the skin, H314 Cat. 1C.
In the eye damage study , the test article was instilled in the right eye of six rabbits. Positive ocular responses were observed at 1, 24, 48 and 72 hours, and on Days 7, 14 and 21 after treatment. Blistering and ulceration of the cornea, pannus and keratoconus were observed during the study. Based upon the observations made in the Acute Eye Irritation Test in rabbits, the test substance was determined to be corrosive to the eye under CLP classification criteria. Based on the results of this study, the test material is considered to cause irreversible damage to the eye. Therefore, under the criteria set forth in the CLP guidance document, this substance should be classified as Eye Damage, H318.
