Additional information
This substance, Tall oil + ammonia-ethanolamine reaction by-products (TO + AEA), differs from other substances in the AAI group that are based on fatty acids with polyamines, in that it contains a high amount of hydroxylated polyethylene amines, causing it to display more neutral OH groups, rather than basic primary amine groups. As toxicity is much related to the presence of free primary amine groups, it can be expected that in specifically in aspects of acute toxicity related to direct chemical interactions, this substance shows less effects compared to other AAI substances.
Tall oil + ammonia-ethanolamine reaction by-products was tested for acute oral toxicity in a standard acute oral toxicity according to OECD 401. The LD50 amounted to 4000 mg/kgbw. Animals dosed with levels up to 2250 mg/kg showed piloerection and hypokinesia up to three days, no mortality, and no findings at macroscopic evaluations. At higher dose levels mortality increased, with 100% mortality within one or two days at 6250 mg/kg.
All other studies with AAI substances show somewhat higher acute oral toxicity, but all with a LD50 > 2000 mg/kg bw. There is possibly a small tendency of decreased toxicity with increasing size of the EA.
Acute toxicity data on amidoamines/imidazolines (AAI):
TO + DETA >2000 mg/kg bw ,Cat.5; ATC cut off 2500mg/kg bw
TO + DETA >2000 mg/kg bw, Cat.5; ATC cut off 2500mg/kg bw
TO + TEPA >2000 mg/kg bw, Cat.5; ATC cut off 2500mg/kg bw
C16-18,C18 unsat+TEPA >2000 mg/kg bw, Cat.5; Limit test 20% mortality
TO + PolyAmidoamine >2000 mg/kg bw ,Cat.5; ATC cut off 5000mg/kg bw
TO + AEA 4000 mg/kg bw ,Cat.5
Acute dermal toxicity: A single group of 5 male and 5 female rats was treated at a dose level of 2000 mg/kg bw. There were no deaths and no clinical signs were noted at any stage of the test. LD50 > 2000 mg/kg bw.
Acute inhalation toxicity: Physical-chemical properties of Tall oil + ammonia-ethanolamine reaction by-products indicate a low likelihood for exposure via inhalation having a boiling point > 300 °C and a low vapour pressure (8.4 x 10 -8 Pa at 25°C).
Justification for selection of acute toxicity – oral endpoint
Only available study
Justification for selection of acute toxicity – inhalation endpoint
Likelihood of exposures via inhalation is low considering the high boiling point (> 300 °C) and very low vapour pressure (8.4 x 10-8 Pa at 25°C for this substance).
Justification for selection of acute toxicity – dermal endpoint
Only available study
Justification for classification or non-classification
Acute oral exposure of Tall oil + ammonia-ethanolamine reaction by-products show limited acute toxicity, with a LD50 above 2000 mg/kg bw via oral as well as dermal route. Hence no classification is required.
For acute inhalation toxicity information for classification is lacking, but 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.
