附件四所列物质衍生的改性物质是否也免于注册？

Are modified substances derived from substances listed in Annex IV also exempt from registration?

REACH 附件四所列物质免于注册。如果改性物质仍包含在相同的 EINECS 条目中，则由这些物质衍生的改性物质也可获得豁免；是否适用相同的 EINECS 条目则需视具体情况而定。例如，对于大豆油等植物油（EINECS 编号 232-274-4；CAS 编号 8001-22-7），EINECS 条目明确涵盖了物理改性衍生物。而化学改性（例如氢化）并未提及，因此被认为不包含在内。有关更多信息，请参阅 REACH 第 3(40) 条和注册指南第 2.2.3.3 节 -“REACH 法规附件四中包含的物质”。

Substances listed in Annex IV to REACH are exempt from registration. Modified substances derived from these substances are also exempt if the modified substance is still covered by the same EINECS entry; whether the same EINECS entry applies is a case-by-case decision. For example, for plant oils such as soybean oil (EINECS no 232-274-4; CAS no 8001-22-7) the physically modified derivatives are explicitly covered in the EINECS entry. Whereas chemical modification (e.g. hydrogenation) is not mentioned and hence considered not to be covered.
