Description of key information
Additional information
Fatty acids, C18 unsat, reaction products with pentaethylenehexamine, acetate salts is a UVCB substance derived from natural sources of fatty acids. The substance is the acetate salts of the reaction product of these fatty acids with ethylene amines. As such, testing for most environmental fate and behaviour properties is either extremely difficult or technically unfeasible due to the high complexity of the substance. As Fatty acids, C18 unsat, reaction products with pentaethylenehexamine, acetate salts is composed of multiple complex components it is not possible to present exact values for any given environmental fate endpoint. As such, data that is considered to be representative and applicable has been obtained by reading across to similar substances and by QSAR estimations conducted for components of Fatty acids, C18 unsat, reaction products with pentaethylenehexamine, acetate salts which are considered to be most representative.
OECD 306 biodegradation in seawater tests were conducted for the read-across substance (Fatty acids, C18 unsaturated, reaction products with diethylenetriamine) along with a marine BODIS test. Seawater biodegradation studies were considered to be most appropriate as this is considered to be the main compartment to which the substance will be emitted.
The levels of biodegradation observed in the marine biodegradation and BODIS tests indicate that the substance can be considered inherently biodegradable, not fulfilling specific criteria. Simulation testing for freshwater, sediment, and soil compartments was not considered necessary as no significant emission to these compartments is expected.
A bioaccumulation study conducted to OECD Guideline 305 is considered to be likely to be unfeasible to conduct due to the complex UVCB nature of the substance. However, it is considered unlikely that the substance will have any significant potential for bioaccumulation due to the large molecular size of the components. This is supported by a QSAR conducted for a representative component which had an estimated log BCF of 1.55.
Similarly, experimental means were not considered appropriate for determination of adsorption coefficient and so a QSAR estimation was made for a representative substance. The estimation indicates that the substance will have a very high affinity for adsorption to carbon, which likely represents the majority of components in the substance.
Hydrolysis testing was not considered to be technically feasible for this substance due to its complex, multi-constituent composition.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
