Endpoint summary

Administrative data

Description of key information

Hydrolysis - The registration substance is a complex UVCB material which is highly insoluble in water. It is therefore concluded that it is not technically possible to develop a method to investigate hydrolysis potential. Therefore the endpoint is waived based on Regulation (EC) No 1907/2006 Section 9.2.2.1 Column 2, which gives provision to waive the standard data requirement in instances where the substance is highly insoluble in water.

Phototransformation - the registration substance is not expected to undergo phototransformation.

Biodegradation - the registration substance is insoluble in water and does not significantly biodegrade via screening test (OECD 301b) or an inherent biodegradation test (OECD 302C). Biodegradation is not expected to occur with other environmental media.

Bioaccumulation - A key GLP study conducted according to OECD guideline determined that the registration substance is not bioaccumulative, with a BCF value of <500.

Transportation and Distribution - Given the high adsorption coefficient valies, the majority of the UVCB substance is expected to partition into soil and sediment and is not expected to be mobile in the environment.
