Additional information
Acute oral toxicity:
Oleyl dipropylenetriamine (Triameen O) was tested for acute oral toxicity by Acute Toxic Class method. At 300 mg/kg animals showed hunched posture, uncoordinated movements and/or piloerection between days 1 and 3. No mortality occurred and body weight development was normal.
At 2000 mg/kg all animals showed hunched posture, lethargy, piloerection, uncoordinated movements, laboured respiration, rales, ptosis, hypothermia, watery discharge from the eyes and/or chromodacryorrhoea prior to death. All animals were found dead on Days 2 or 4.
One animal at 2000 mg/kg showed a stage of beginning autolysis. No macroscopic abnormalities were noted in the other animals at 2000 mg/kg, and in the animals at 300 mg/kg.
The oral LD50 value of Oleyl dipropylenetriamine in Wistar rats was established to be within the range of 300-2000 mg/kg body weight, with a cut-off value of 500 mg/kgbw.
Comparable other triamines (alkyl dipropylenetriamine) and tetramines (alkyl tripropylenetatramine) show similar results, where those with on average shorter alkyl chains show a somewhat higher toxicity compared to those with longer alkyl chain lengths:
Acute toxicity Triamines:
Coco 50-300 mg Cat.3; cut off 200
Tallow 300-2000 mg Cat.4; cut of 500
Oleyl 300-2000 mg Cat.4; cut of 500
Acute toxicity Tetramines:
Tallow 300-2000 mg Cat.4; cut of 500
Oleyl 300-2000 mg Cat.4; cut of 1000
In conclusion, there is little effect of the actual number propylene amine groups between linear triamine or linear tetramine. With increasing length of the alkyl chain, the acute toxicity decreases.
Acute dermal toxicity:
Polyamines 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.
The mode of action of for polyamines follows from its structure, consisting of an apolar fatty acid chain and a polar end of a primary amine linked to a secondary amine. The structure can disrupt the cytoplasmic membrane, leading to lyses of the cell content and consequently the death of the cell.
The polyamines are completely protonated under environmental conditions which causes them to strongly adsorb to organic matter. This all leads to a low dermal absorption as is shown by a dermal absorption study performed on a structurally related branched triamine (Dodecyl dipropylenetriamine, CAS 2372-82-9) for 24 hours, resulted in a dermal penetration of less than 0.01% whereas 0.92% of the applied dose did pass the stratum corneum but remained further fixed in the skin (Report not included in this dossier)
For the linear polyamines a similar and even lower (in case of higher alkyl chain lengths) dermal penetration can be expected.
Acute inhalation toxicity:
Physical-chemical properties of Oleyl dipropylenetriamine indicate a low likelihood for exposure via inhalation. The substance has a boiling point > 300 °C and a low vapour pressure (4.7 x 10-5 Pa at 20°C for the coco dipropylenetriamine, with the shortest average alkyl chain length representing the highest vapour pressure for this group of polyamines). Its use is limited to industrial and professional users and does not involve the forming of aerosols, particles or droplets of an inhalable size. So exposure to humans via the inhalation route will be unlikely to occur. Furthermore, as the substance is classified as corrosive, such testing should normally not be conducted.
Justification for classification or non-classification
Acute oral exposure of Oleyl tripropylenetetraamine leads to harmful effects, with a LD50 between 300 and 2000 mg/kg bw. The substance therefore need to classified as “ Cat.4 harmful if swallowed” for acute oral toxicity for GHS.
Acute dermal testing with these very 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.
Also for acute inhalation toxicity information for classification is lacking, and is testing not justified. The likelihood of exposure via inhalation low.
No classification STOT-SE Cat.3 needed:
Polyamines are not structurally related to any known class of neurotoxic chemicals. In addition, repeated dose studies did not show indications of specific neurotoxicity, in specific neurotoxicity measures as sensory activity, grip strength, and motor activity assessment.
Polyamines do not contain containing aliphatic, alicyclic and aromatic hydrocarbons and so do not indicate an immediate concern for aspiration hazard.
