Natural polymers are understood as polymers which are the result of a
polymerisation process that has taken place in nature, independently of the
extraction process with which they have been extracted (i.e. they may or may not fulfill the criteria set out in Article 3(39) of the REACH Regulation).
Following Article 2(9) of the REACH Regulation, any polymer meeting the
criteria of Article 3(5) of the REACH Regulation does not have to be
registered. This includes natural polymers which are chemically modified
(e.g. post-treatment of natural polymers). Monomer substance(s) or other substance(s) in the form of monomeric units and chemically bound substance(s) originating from the natural polymer can for practica l
reasons be treated as “non-isolated intermediates” and do not have
to be registered. The substances used to chemically modify the natural
polymer and which are chemically bound within the final polymer need
to be registered according to the REACH requirements.
