Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Harlan, Belton, Leics, England.
- Age at study initiation: at least 6 weeks
- Weight at study initiation: at least 1.0 kg
- Housing: The animal was individually housed in a labeled cage with perforated floor and shelter
- Diet (e.g. ad libitum): Pelleted diet for rabbits (Global Diet 2030 from Harlan Teklad®, Mucedola, Milanese, Italy) approximately 100 grams per day. Hay (TecniLab-BMI BV, Someren, The Netherlands) was provided at least three times a week.
- Water (e.g. ad libitum): Free access to tap water.
- Acclimation period: The acclimatization period was at least 5 days before the start of treatment under laboratory conditions.
A health inspection was performed prior to the commencement of treatment, to ensure that the animal was in a good state of health. Special attention was paid to the skin to be treated, which was intact and free from abnormalities.
Results of analysis for diet (nutrients and contaminants), hay and water were assessed and did not reveal any findings that were considered to have affected the study integrity. All certificates and results of analysis are retained in the NOTOX archives.
Animal specifications (sex, age and body weight) are specified in the attached table.
ENVIRONMENTAL CONDITIONS

- Humidity (%): 44 - 74%
Cleaning procedures in the room might have caused the temporary fluctuations above the optimal maximum level of 70% for relative humidity. Based on laboratory historical data, these fluctuations were considered not to have affected the study integrity.
- Air changes (per hr): approximately 15
- Photoperiod (hrs dark / hrs light): 12/12

- Controls:

- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.5 grams - Duration of treatment / exposure:
- Single application.
- Observation period:
- up to 4 hours after the first application when the single treated animal was sacrificed for ethical reasons.
- Number of animals:
- 1 (based on the severe skin reactions, no further animals were exposed to the test substance)
- Details on study design:
- STUDY DESIGN
The study was performed in a stepwise manner and started with the treatment of one animal (sentinel) with a stepwise exposure regime. Based on the severe skin reactions, no further animals were exposed to the test substance.
TEST SUBSTANCE PREPARATION
The test substance was applied as delivered by the sponsor.
TEST SITE
Approximately 24 hours before treatment, the dorsal fur was clipped with electric clippers, exposing an area of approximately 150 square centimeters (10x15 cm).
REMOVAL OF TEST SUBSTANCE
After each removal of a dressing, the treated skin was cleaned of residual test substance using water and ethanol.
After the final observation, the animal was sacrificed by intra-venous injection of Euthasol® 20% (AST Farma BV, Oudewater, The Netherlands).
OBSERVATIONS
Mortality/Viability: Twice daily.
Toxicity: At least once daily.
Body Weight: Day of treatment (prior to application).
Necropsy: No necropsy was performed.
The skin reactions of all visible treated sites were assessed immediately after removal of a dressing. The irritation scores and a description of all other (local) effects were recorded. Adjacent areas of untreated skin of the animal served as controls.
SCORING SYSTEM:
The irritation was assessed according to the following numerical scoring system. At each observation, the highest scores given were recorded:
Erythema and eschar formation:
0: No erythema
1: Very slight erythema (barely perceptible)
2: Well-defined erythema
3: Moderate to severe erythema
4: Severe erythema (beet redness) *
*. Where signs of necrosis or corrosion (injuries in depth) prevent erythema scoring, the maximum grade for erythema (= 4) was given.
Oedema formation:
0: No oedema
1; Very slight oedema (barely perceptible)
2: Slight oedema (edges of area well-defined by definite raising)
3: Moderate oedema (raised approximately 1 millimeter)
4: Severe oedema (raised more than 1 millimeter and extending beyond the area of exposure)

- Irritant / corrosive response data:
- A 3-minute exposure to 0.5 g of Oleyl tripropylenetetramine (C18 dipropylene tetraamine) resulted in very slight erythema at 1 and 4 hours after exposure.
A 1-hour exposure resulted in very slight erythema immediately after exposure and in well defined erythema at 3 hours after exposure.
A 4-hour exposure resulted in dark brown discolouration surrounded by grey discolouration at the edge of the application area (sign of necrosis) immediately after
exposure.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1C (corrosive) based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- Oleyl tripropylenetetramine (C18 dipropylene tetraamine) should be classified as : skin corrosive (Category 1C).
- Executive summary:
One rabbit was exposed to three samples of 0.5 grams of Oleyl tripropylene tetramine (C18dipropylene tetraamine) applied to separate skin-sites on intact, clipped skin using a semi-occlusive dressing. The exposure periods were 3 minutes, 1 hour and 4 hours, respectively. Skin reactions were assessed up to 4 hours after the 3-minute exposure. Based on severe skin reactions, no further animals were exposed to the test substance.
A 3-minute exposure to 0.5 g of Oleyl tripropylene tetraamine (C18dipropylene tetraamine) resulted in very slight erythema at 1 and 4 hours after exposure. A 1-hour exposure resulted in very slight erythema immediately after exposure and in well defined erythema at 3 hours after exposure.
A 4-hour exposure resulted in dark brown discolouration surrounded by grey discolouration at the edge of the application area (sign of necrosis) immediately after exposure. Sticky or dry remnants of the test substance were present on the skin after exposure. The dark brown discolouration surrounded by grey discolouration at the edge of the application area are signs of necrosis. Following this observation, the animal was sacrificed for humane reasons. These severe skin reactions are expected to result in deep and thick scab formation with possible ruptures of the scab, or the scab may drop off exposing scar tissue. Overall, these skin reactions were considered evidence of full thickness destruction of the skin, and hence no further animals were tested. Based on these results and according to the:
- Globally Harmonized System of Classification and Labeling of Chemicals (GHS) of the United Nations (2007), Oleyl tripropylene tetramine (C18dipropylene tetraamine) should be classified as : skin corrosive (Category 1C).
- Regulation (EC) No 1272/2008 on classification, labeling and packaging of substances and mixtures, Oleyl tripropylene tetramine (C18dipropylene tetraamine) should be classified as Corrosive (Category 1C) and labeled as H314: Causes severe skin burns and eye damage.
