Additional information
Skin irritation/corrosion:
An in vitro skin irritation study is available with Amines, polyethylenepoly-, tetraethylenepentamine fraction (Gordon, 1994). This study was carried out for validation purposes of the OECD 435 testing guideline. The Corrositex ® test kit was used. Only a summary table is available. Amines, polyethylenepoly-, tetraethylenepentamine fraction was tested as neat substance. The test substance showed a full-thickness destruction of the biobarrier membrane after 1 hour and 1 minute. Based on the definition given in the publication this would lead to a Corrosive Packing Group III which is equivalent to CLP/EU Category 1C. It was however indicated that the standard deviation was “not done” which seems to mean that it was tested only once. With a possible variation of e.g. a few minutes for such a one hour period it can be speculated that Amines, polyethylenepoly-, tetraethylenepentamine fraction could be classified as borderline between Cat. 1B and 1C. Ethylenediamine (100%) showed a barrier breakthrough of 13 minutes with a standard deviation of 30 seconds, resulting in classification into PG II (CLP corrosion Cat. 1B). Amines, polyethylenepoly-, triethylenetetramine fraction showed a barrier breakthrough at 49 minutes (with a standard variation of 1.19 min) and as such should be classified in Cat. 1B. Although it was indicated that Amines, polyethylenepoly-, triethylenetetramine fraction was tested as a 60% concentration, but considering that breakthrough time seems to increase with increasing length of the ethylene amines (order EDA, TETA, TEPA), the results for 100% TETA can be expected also to fall into Cat. 1B. Considering the available data, classification in Cat. 1B seems most appropriate for Amines, polyethylenepoly-, tetraethylenepentamine fraction.
Two further skin irritation studies performed pre-GLP and pre-guideline with the registration substance are available (Myers, 1979 and Dow, 1965). The information on the study design is very limited and no detailed scores are reported. However, the test substance was applied to the bellies of rabbits. In one study 3 of 5 rabbits necrosis was observed (Myers, 1979) leading to the conclusion that the test substance is corrosive. In the second study the test substance led to crustations which healed without scars.
Based on the observed results the registration substance is considered to be corrosive to skin (Cat. 1B).
Eye irritation
Only limited data is available with Amines, polyethylenepoly-, tetraethylenepentamine fraction. Two eye irritation studies performed pre-GLP and pre-guideline with the registration substance indicate that the test substance might have eye damaging properties (Myers, 1979 and Dow, 1965). Since no information on the study design and no detailed scores are reported, those studies cannot be used for a final hazard conclusion. However, as described above Amines, polyethylenepoly-, tetraethylenepentamine fraction is considered to be corrosive to skin thus no further testing is required.
Justification for classification or non-classification
Reliable data with the registration substance on skin irritation indicate that the registered substance meets the criteria for classification according to Regulation (EC) No. 1272/2008. The test substance is therefore classified as corrosive to skin Cat. 1B (H314). As the registration substance is classified as corrosive to skin and thus leading to a classification as serious eye damage (Cat. 1, H318). No further testing on eye irritation is required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
