Additional information

Condensation Product of N-C12-C18-Alkylpropane-1,3-Diamine, N-(3-Aminopropyl)-Nā€™-C12-C18-Alkylpropane-1,3-Diamine and Formic Acid biodegradation

potential has been assessed in the frame of an OECD 301 test carried out according to GLP procedures. The results indicate that the substance is not readily biodegradable.

No additional test is proposed to better characterize behaviour and biodegradation profile of this substance.

Indeed,in the REACH Guidance this is indicated that for adsorptive substances, a lower degradation rate is generally expected in soil than in water-phase due to partly immobilization caused by sorption.

Condensation Product of N-C12-C18-Alkylpropane-1,3-Diamine, N-(3-Aminopropyl)-Nā€™-C12-C18-Alkylpropane-1,3-Diamine and Formic Acid

is a cationic surfactant and thus sorbs easily to negatively charged surfaces. There is no principal difference between soil and sediments considering the sorption properties. Therefore, further testing in soil and sediment are not expected to deliver more information on the biodegradation of this substance. In adddition, these tests will be technically not feasible with this UVCB substance. Thus we decided to investigate the bioaccumulation of the substance in order to assess the PBT/vPvB criteria of the substance.
