Key value for chemical safety assessment

Additional information

According to regulation (EC) no 1907/2006, Annex XI, paragraph 1.5., substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or "category" of substances. Environmental effects or environmental fate may be predicted from data for reference substance(s) within the group by interpolation to other substances in the group (read-across approach).

The analogue substance is a sterically hindered amine with functional groups that are almost identical to EC no. 41 -990 -0. Its physicochemical properties are similar and comparable to each other. Furthermore, both substances have similar environmental fates. Thus, the analogue substance is regarded as suitable for read across.
