Additional information
Skin irritation
In a skin irritation / corrosion study (BASF 1970) the test substance was applied to two white Vienna rabbits for 1 min, 5 min, 15 min and 20 h under occlusive conditions. Animals were observed for 8 days and skin changes were observed. Findings were recorded after 24 hours and at the end of the observation period. After 24 hours (5 -15 min exposure) marked erythema was observed in both animals and slight edema in animal #1. The observed erythema was not reversible within 8 days. In addition necrosis was observed in animal #1 and hardening of the skin in both animals. At 24 hours (after 20 h exposure) marked erythema was observed in both animals and slight edema in animal #1 and strong edema in animal #2. The observed erythema was not reversible within 8 days. In addition, necrosis was observed in both animals and transverse folds in the skin in both animals.
Eye irritation
In an eye irritation study (BASF 1970) two Vienna white rabbits were exposed to 0.05 mL of the test substance followed by an observation period of 8 days. Observations were made after 1 hour, 24 hour and 8 days. After 1 hour, marked redness and corneal opacity was observed in both animals. In addition, marked chemosis in animal #1 and severe chemosis in animal #2 was noted. After 24 hours, marked chemosis and corneal opacity was observed in both animals. Hemorrhages were also observed in both animals. In addition, iritis was present in both animals After 8 days, slight erythema and slight to marked corneal opacity were present in both animals. In addition, staphyloma and ingrowing vessels were observed in both animals.
Justification for selection of skin irritation / corrosion
endpoint:
One skin irritation / corrosion study is available. This study is
adequate for covering this endpoint.
Justification for selection of eye irritation endpoint:
One eye irritation study is available. This study is adequate for
covering this endpoint.
Effects on skin irritation/corrosion: corrosive
Effects on eye irritation: corrosive
Justification for classification or non-classification
Based on the severity and irreversibility of the observed effects, the test substance is classified as Skin corrosive category 1B, H314: Causes severe skin burns and eye damage in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
Because severe eye effects (staphyloma) were observed after ocular application at a concentration half the amount required in the OECD 405 guideline, the test substance has to be classified as Eye damage 1: H318: Causes serious eye damage in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
