To support the aim of eventual replacement of substances of very high concern by suitable
alternative substances or technologies, all applicants for authorisation should provide an
analysis of alternatives considering their risks and the technical and economic feasibility of
substitution, including information on any research and development the applicant is
undertaking or intends to undertake. Furthermore, authorisations should be subject to
time-limited review whose periods would be determined on a case-by-case basis and
normally be subject to conditions, including monitoring.
(73) Substitution of a substance on its own, in a preparation or in an article should be required
when manufacture, use or placing on the market of that substance causes an unacceptable
risk to human health or to the environment, taking into account the availability of suitable
safer alternative substances and technologies, and the socio-economic benefits from the
uses of the substance posing an unacceptable risk.
