Description of key information

Skin irritating potential of the test substance was assessed in three in vivo skin irritation studies. Slight to moderate erythema and edema were observed, not fully reversible within 8 days. Therefore, the test substance is considered to be a skin irritant.
The test substance causes severe eye damage in the available eye irritation studies in vivo.

Additional information

Skin irritation/corrosion

The test item was assessed for skin irritating properties in a study performed in rabbits (BASF, 1971). After 20 hours of test substance exposure slight to moderate erythema and edema were observed and the erythema score was determined to be 2 and 3 in animal 1 and 2, respectively, not fully reversible after 8 days. Therefore, the test substance was considered to be irritating to the skin.

This evaluation is supported by further non standard skin irritation studies available. In both studies (BASF, 1973,1958) slight irritating properties to the skin of rabbits were noted. A clear evaluation with regard to classification and labelling was not possible in these supporting non standard studies.

 

Eye irritation

The test item was assessed for eye irritating properties in a non-GLP study performed in rabbits. Based on the results of the key study (BASF, 1971), the substance was considered as severely eye damaging (cornea score: 3, conjunctivae score: 2, chemosis score: 2). The results of the key study were confirmed by two supporting non-GLP studies (BASF, 1973,1958) performed in rabbits, revealing eye damaging properties of the test item.

Justification for selection of skin irritation / corrosion endpoint:
Most current in vivo study.

Justification for selection of eye irritation endpoint:
Most current in vivo study.

Effects on skin irritation/corrosion: irritating

Effects on eye irritation: highly corrosive

Justification for classification or non-classification

Based on the results obtained in the skin irritation/corrosion tests, the test item is classified as follows:

- R38 Irritating to the skin (according to Directive 67/548/EEC).

- H315 Causes skin irritation, Cat.2 (according to Regulation (EC) No 1272/2008).

 

Based on the results obtained in the eye irritation tests, the test item is classified as follows:

- R41 Risk of serious damage to eyes (according to Directive 67/548/EEC).

- H318 Causes serious eye damage, Cat.1 (according to Regulation (EC) No 1272/2008).
