- Executive summary:
Assessment of acute oral toxicity with Tall oil reaction products with tetraethylene-pentamine in the rat (Acute Toxic Class Method).
The study was carried out based on the guidelines described in:
- OECD No.423 (2001) "Acute Oral Toxicity, Acute Toxic Class Method"
- Commission Regulation (EC) No 440/2008, B1 tris: "Acute Oral Toxicity, Acute Toxic Class Method"
- EPA, OPPTS 870.1100 (2002), "Acute Oral Toxicity"
- JMAFF guidelines (2000) including the most recent partial revisions.
Initially, Tall oil reaction products with tetraethylene-pentamine was administered by oral gavage to three female Wistar rats at 300 mg/kg body weight. In a stepwise procedure additional groups of females were dosed at 300 and 2000 mg/kg body weight. All animals were subjected to daily observations and weekly determination of body weight. Macroscopic examination was performed on the day of death or after terminal sacrifice (Day 15).
One female at 2000 mg/kg was found dead on Day 2. No mortality occurred among other animals at 2000 mg/kg, or among animals at 300 mg/kg.
Clinical signs observed during the study period were as follows:
Dose level Clinical signs
300 mg/kg Lethargy, hunched posture, uncoordinated movements and/or piloerection on Day 1.
2000 mg/kg Hunched posture and/or piloerection between Days 1 and 4.
The mean body weight gain shown by the surviving animals over the study period was considered to be normal.
No abnormalities were found at macroscopic post mortem examination of the animals.
The oral LD50 value of Tall oil reaction products with tetraethylene-pentamine in Wistar rats was established to exceed 2000 mg/kg body weight.
According to the OECD 423 test guideline, the LD50 cut-off value was considered to be 2500 mg/kg body weight.

Additional information
Data can be used for read-across to Aradur 223 as detailed in the justification document attached in section 13.
Fatty acid C18 unsaturated + TEPA was tested for acute oral toxicity according to acute toxic class method. The study showed one death out of 6 dosed at 2000 mg/kg, and no mortality at 300 mg/kg.
At 300 mg clinical signs included lethargy, hunched posture, uncoordinated movements and/or piloerection on Day 1.
All other studies with AAI substancesshow similar acute oral toxicity, all with a LD50 > 2000 mg/kg bw. There is possibly a small tendency of decreased toxicity with increasing size of the EA.

Acute dermal toxicity:AAI are corrosive to the skin. Testing for acute dermal toxicity is therefore not justified. Toxicity following dermal exposure is characterised by local tissue damage, rather than the result of percutaneously absorbed material.
Acute inhalation toxicity:Physical-chemical properties of AAI indicate a low likelihood for exposure via inhalation having a boiling point > 300 °C and a low vapour pressure (0.00017 mPa at 25°C for DETA based AAI). Furthermore, the substance is classified as corrosive and no acute toxicity testing should normally be conducted
Justification for classification or non-classification
Data can be used for read-across to Aradur 223 as detailed in the read-across justification document attached in section 13.
Acute oral exposure of Tall oil + TEPA show limited acute toxicity, with a LD50 above 2000 mg/kg bw. Hence no classification is required.
Acute dermal testing with corrosive materials is not justified. As a consequence no classification can be made for acute dermal toxicity. Effects will be characterised by local tissue damage. Systemic uptake via skin is likely to be very limited. The low acute oral toxicity indicate a low systemic toxicity.
No classification for acute dermal toxicity is therefore indicated.
Also for acute inhalation toxicity information for classification is lacking, and is testing not justified. Due to very low vapour pressure is the likelihood of exposure low.
AAI do not contain containing aliphatic, alicyclic and aromatic hydrocarbons and have a relatively high viscosity and so do not indicate an immediate concern for aspiration hazard.
