This Substance Identification Profile (SIP) is developed to represent the Identification parameters of the
substance described in line with the Substance Identification requirements of REACH Annex VI and relevant
guidance for the purpose of identifying the registered substance and the provision of a 'boundary
composition' for IUCLID 6 dossier updates.

Solid: Particulate / Powder
More than 90% of particles have a diameter of
<100nm
Considered to pose an
inhalation risk
Depending on method of
particle size
determination it cannot
be excluded that the
substance falls under the
proposed horizontal EU
nano definition from
2011, but since validated
methodology is missing
