- Irritant / corrosive response data:
- animals have been exposed for 60min, 4h, and 24h. All animals scored 4 (necrosis) for erythema and edema immediately after unwrapping.
Severe erythema and severe edema remained present in all animals at all observation periods during the study (up to 14 days). - Interpretation of results:
- other: CLP/EU GHS Category 1B (H314) according to Regulation (EC) No 1272/2008
- Conclusions:
- The test article was considered to be severe dermal irritant at both 4 and 24 hour exposures.
The Dermal Irritation Toxicity Category is Class I (corrosive).
The DOT Packing Group Classification is Class I (corrosive at less than 3 min).
Primary Dermal Irritation Index at 4h and 24h exposure=8.00 (according to Draize scoring system).
No reading time point at 1 hour after 3-minute exposure was available in order to definetly find a conclusion on subcategory 1A or 1B. Since after immediate observation after 3-minute exposure well-defined erythema (score 2) was found in 3 out of 6 animals it is not assumed that after on hour necrosis would have been formed. Therefore, a classification category 1B is considered. - Executive summary:
The test substance was examined undiluted for skin irritation in groups of 3 rabbits per sex. The test material was applied (semi-occlusive) directly on the intact and abraded skin sites. The skin was abraded using a burred needle, the abrasion penetrated the stratum corneum, but not the derma. The test article was administrated once per site for 3 min, 60 min, 4h, or 24 h. Necrosis was observed after 3 min exposure. The animals that had been exposed for 60 min, 4 h, or 24h scored 4 (necrosis) for erythema and edema immediately after unwrapping. Severe erythema and severe edema remained present in all animals at all observation periods during the study (up to 14 days).

Additional information
Skin irritation/corrosion:
An in vitro skin irritation study is available with Amines, polyethylenepoly-, triethylenetetraamine 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-, triethylenetetraamine fraction was tested as 60% solution. The test substance showed a full-thickness destruction of the biobarrier membrane after 49 minutes with a standard deviation of 1 minute and 19 seconds. Based on the definition given in the publication this would lead to a Corrosive Packing Group II which is equivalent to CLP/EU Category 1B.
A key study according to OECD guideline 404 with the registration substance is available (Pharmakon, 1992). Amines, polyethylenepoly-, triethylenetetramine fraction was examined at concentrations of 100%, 50%, 25%, and 5% in groups of 3 New Zealand White rabbits per sex. The test material was applied (semi-occlusive) directly on the intact and abraded skin sites. Only the results on intact sites are considered for hazard assessment. The test substance was administrated once per site for 3 min, 60 min, 4h, or 24 h.
Applying 100% of the registration substance to rabbit skin resulted in necrosis after 3 min of exposure. Necrosis was observed 24 hours after treatment. Immediately after unwrap very slight (score 1, 2/6 animals) or well-defined (score 2, 3/6 animals) erythema was observed. One animal showed no signs of irritation immediately after unwrap but developed necrosis at 72 hours after exposure. The animals that had been exposed for 60 min, 4 h, or 24h scored 4 (necrosis) for erythema and edema immediately after unwrapping. Severe erythema and severe edema remained present in all animals at all observation periods during the study (up to 14 days).
50% solution of the registration substance: Very slight erythema was observed in one animal after the 24 -hour observation period at the 3 -minute expsoure site. No other signs of erythema, edema or necrosis was observed during the study at this site. Immediately after unwrap at the 60 minute exposure site, very slight erythema was observed in three rabbits and necrosis, severe erythema and severe edema was observed in the three remaining rabbits. Necrosis, severe erythema and severe edema was observed in three rabbits at 24 hours through day 13 and continued in one rabbit to day 14. At the 4 -hour exposure site, very slight or well-defined erythema and no edema was observed in all six rabbits immediately after unwrap and continued in two rabbits to 48 hours. Necrosis, severe erytema and severe edema was observed in one rabbit at 24 hours and continued through day 14.
25% solution of the registration substance: No signs of erythema, edema or necrosis were observed at any observation period at the 3 -minute exposure site. Very slight to severe erythema and slight to severe edema were observed at the 60 -minute exposure site at the immediate and 24 hour observation periods. Necrosis, severe erythema and severe edema were observed in one rabbit at 24 hours and in two rabbits at 48 hours through day 11. All scores for the 60 -minute exposure returned to normal on day 12. At the 4 -hour exposure site, very slight or severe erythema and not edema were observed in four rabbits immediately after unwrap. Necrosis, severe erythema and severe edema were observed in one rabbit for the remainder of the study.
For the 5% test substance just one of 6 animals showed an erythema score of 1 at 24 hour observation time point after 4 hour exposure. All other scores for the 4 hour exposure was 0 for erythema and edema. No signs of erythema and edema were observed after 24h exposure on the intact site. No signs of necrosis were observed after 3 min, 60 min and 4 h and 24 h exposure time.
A supporting skin irritation study performed pre-GLP and pre-guideline according to an internal BASF test with the registration substance is available (BASF, 1966). The registration substance was examined undiluted for skin irritation. Two Vienna White rabbits were treated for 1, 5, 15 min and 20 hours using occlusive conditions. The application site was covered with the undiluted test substance. After the application time (1, 5, 15 min) the skin was washed with Lutrol. Effects were examined after 10 minutes, 1, 24, 48, 72 hours as well as after 8 days. After a 5 min exposure bleeding and at the end of the observation period after 8 days scale formation was observed. After a 15 min or 20 h exposure soft necrosis (24 h evaluation) was observed which turned into a leathery necrosis at the end of the observation period. It was concluded that the test substance caused necrosis after a 15 min exposure.
Two further skin irritation studies performed pre-GLP and pre-guideline with the registration substance are available (Meyers, 1976 and Oyen, 1953). Since no information on the study design and no detailed scores are reported, those studies cannot be used for hazard assessment and are thus disregarded.
Based on the observed results the registration substance is considered to be corrosive to skin (Cat. 1B).
Eye irritation
A key study according to OECD guideline 405 with Amines, polyethylenepoly-, triethylenetetramine fraction is available (Pharmakon, 1993). Eye irritation of Amines, polyethylenepoly-, triethylenetetramine fraction was tested in one female New Zealand White rabbit. The registration substance was applied undiluted to the eye for 1 second. Vocalization occurred immediately after test article administration. Due to the extreme ocular scores observed, the study was terminated at the study director's discretion after the 1 -hour observation period.
A supporting eye irritation study performed pre-GLP and pre-guideline according to an internal BASF test with the registration substance is available (BASF, 1966). 50 μL of the test substance was applied to the conjunctival sac of one eye in 2 Vienna White rabbits. The animals were observed after 10 min, 1 and 3 h on the day of treatment and up to 8 days afterwards. Findings were recorded daily. The eyes were not washed out after 24 hours as specified in OECD Guideline 405. A corneal opacity score of 3 was observed in both animals until the end of observation on day 8. 10 min after application corrosion of the nicktating and mucous membrane was noted. 24 h (animal 1) and 48 h (animal 2) post application suppuration was noted. In animal 2, 48 h post application iritis occurred. The application of the test substance caused corrosion to the exposed eyes, predominantly expressed by severe corneal opacity.
Two further eye irritation studies performed pre-GLP and pre-guideline with the registration substance are available (Meyers, 1976 and Oyen, 1953). Since no information on the study design and no detailed scores are reported, those studies cannot be used for hazard assessment and are thus disregarded.
Based on the observed results Amines, polyethylenepoly-, triethylenetetramine fraction is considered to be severe eye damaging (Cat. 1).
Justification for classification or non-classification
Reliable data with the registration substance on skin and eye irritation conclude 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) and damaging to eyes Cat. 1 (H318).
