Description of key information

The aquatic photolytic degradation is not considered to have relevant impact on the overall persistency of UV-360 in the aquatic environment.

Key value for chemical safety assessment

Additional information

Photolytic degradation of UV-360 is expected to be a relevant degradation process only in very shallow clear waters and in the first few centimetres of the water column, decreasing rapidly in the lower layers of the water column, if at all. It is expected that the environmental exposure of the substance occurs in the whole water column. Because of the substance’s adsorption potential it will predominantly bind to suspended organic matter and sediment which is supposed to decrease the tendency for photolytic degradation. Therefore aquatic photolytic degradation is not considered to have relevant impact on the overall persistency of UV-360 in the aquatic environment.
