Description of key information

Additional information

The substance 1-Propaneamine, 3-(isodecyloxy)- (CAS no 30113 -45 -2) consists mainly of etheramine with carbon chain lengths of C9 – C11 (rich on C10). It is not neutralised with acetate. For some studies, read-across has been performed with

1 -Propaneamine, 3 -(isodecyloxy)- acetate, which has the same chemical structure, but is neutralised with acetate. The acetate is not expected to have an impact on the environmental fate properties. Synonyms are 3-(Isodecyloxy) propylamine and 3 -(Isodecyloxy)propane-1-amine.

Abiotic degradation

A hydrolysis test has been waived because the substance is readily biodegradable in accordance with column 2 of Annex VIII of Regulation 1907/2006/EC. Hydrolysis is expected to be negligible on the basis of the chemical structure. According to EPIWIN calculations the reaction with OH-radicals in air would result in a half-life time in air in the order of a few hours. However the substance is not expected to volatilise to any significant extent.

Biodegradation

In a ready biodegradation study with 1 -Propaneamine, 3 -(isodecyloxy)- acetate according to OECD TG 301D (GLP, reliability 1) 68% oxidation was found after 28 days. The study demonstrates that also the test substance 1-Propaneamine, 3-(isodecyloxy)-

is readily biodegradable.

Bioaccummulation

The substance is expected to have a low bioaccumulation potential based on the low log Kow. Log Kow of -0.34 was determined with the slow stirring method for 3-(Isodecyloxy)propylamine.

Transport and distribution

The mean Kd was experimentally determined to be 2010 L/kg (range 940 - 2590) indicating a moderate sorption potential.
