Additional information
Acute oral toxicity:
The acute toxicity of Cocodipropylenetriamine was determined according to OECD Guideline 423 in compliance with GLP. A group of young female Wistar rats received an oral gavage dose of the test substance in propylene glycol (10 mL/kg bw), at a dose level of 300 (one test group comprising 3 females) and 50 mg/kg bw (two test groups comprising 3 females).
All animals of the 300 mg/kg bw group showed hunched posture from one hour after dosing, piloerection from 2 hours after dosing, and lethargy, uncoordinated movements and/or ptosis 4 hours after dosing. All animals were found dead the day after administration. Two animals at 300 mg/kg showed a stage of beginning autolysis, along with red foci on the glandular mucosa in one of these animals. No macroscopic abnormalities were noted in the other animal at 300 mg/kg.
All animals treated with 50 mg/kg bw survived, and showed hunched posture, salivation, piloerection and/or rales between days 1 and 6. The body weight gain shown by the animals at 50 mg/kg over the study period was considered to be normal. No macroscopic abnormalities were noted
The oral LD50 value of cocodipropylenetriamine in Wistar rats was established to be within the range of 50-300 mg/kg body weight. The LD50 cut-off is set at 200 mg/kg bw based on the mortality of all three animals at first step at 300 mg/kg.
Acute inhalation toxicity:
Physical-chemical properties of Cocodipropylenetriamine indicate a low likelihood for exposure via inhalation. The paste has a boiling point > 300 °C and a low vapour pressure (4.7 x 10-5 Pa at 20°C).
In accordance with Annex VIII Column 2 of REACH, the acute toxicity study by inhalation does not need to be conducted as the test substance has a low vapour pressure. Furthermore, as the substance is classified as corrosive, such testing should normally not be conducted.
Besides, no testing is required for on-site isolated intermediates handled under SCC.
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.
Justification for selection of acute toxicity – oral endpoint
Only one guideline-compliant study is available.
Justification for selection of acute toxicity – inhalation endpoint
: Low likelihood for exposure via inhalation; bp > 300 ºC and vapour pressure 0.05 mPa at 20°C.
Justification for selection of acute toxicity – dermal endpoint
In accordance with column 2 of REACH Annex VIII, the acute dermal toxicity study does not need to be conducted when the substance is classified as corrosive to the skin.
Justification for classification or non-classification
Based on an acute oral LD50 cut-off of 200 mg/kg bw, Cocodipropylenetriamine qualifies for classification Acute Tox. 3 (H301 - Toxic if swallowed.) according to Regulation (EC) 1272/2008.
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 is 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.
