Description of key information
Additional information
Abiotic degradation or biodegradation are no relevant environmental
pathways for Amines, polyethylenepoly (PEPA). The substance is not prone
to hydrolysis or biodegradation by microorganisms. The substance
characteristics i.e. a high water solubility (WS >50 g/L) and low vapour
pressure (VP: 0.00077 Pa) indicate that the substance will be mainly
dissolved and distributed by water. Volatilisation and distribution via
the atmosphere is not likely. Data on the adsorption potential is
available for the structurally analogue substance Penta ethylene
hexamine (CAS 4067-16-7). In accordance with Article 13 (1) of
Regulation (EC) No 1907/2006, "information on intrinsic properties of
substances may be generated by means other than tests, provided that the
conditions set out in Annex XI are met.” According to Annex XI, Item
1.5, of Regulation (EC) No 1907/2006 substances can be considered
similar if their physicochemical, toxicological and ecotoxicological
properties are likely to be similar or follow a regular pattern as a
result of structural similarity. A detailed
justification of the Analogue Approach is attached to IUCLID section 13.
A log Koc <3.5 was determined for the source substance Penta ethylene
hexamin. The value indicates a potential for
adsorption to suspended soil and sediment particles. Based on above
mentioned physico-chemical characterises (log Koc, WS and VP) Amines,
polyethylenepoly (PEPA) is expected to mainly distribute to water as
well as soil and sediment when released to the environment.
PEPA is no expected to bioaccumulate in aquatic or sediment organisms due to the low calculated log Pow of - 3.67.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
