Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Laser diffraction data for copper (I) chloride show volume-rated D (v,0.5) values of 35.83 - 157.67 µm. The number-based D (n,0.5) values are 1.83 -16.17 µm. Based on the results from the number distribution, the material is not considered to fall under the EC’s recommended definition of nanomaterial (50% < 100 nm based on particle number). Joint registrants that produce or import copper (I) chloride corresponding to this specification are able to refer to these granulometry data for the purpose of REACH registration.
Additional information
The Lead Registrant produces copper (I) chloride with the following volume-rated particle size distribution: D(v, 0.1) 61.50, D(v,0.5) 157.67 and D(v,0.9) 316.67 µm, respectively. Values for the number-rated distribution were determined to be D(n,0.1) 9.45, D(n, 0.5) 16.17 and D(n,0.9) 56.69 µm, respectively.
Giusto Faravelli, a member of the joint submission, has also submitted PSD data for inclusion in this dossier in order to demonstrate the range of particle size distributions produced by the industry. In this case, the volume-rated particle size distribution is as follows: D(v, 0.1) 6.77, D(v,0.5) 35.83 and D(v,0.9) 112.76 µm, respectively. Values for the number-rated distribution were determined to be D(n,0.1) 1.16, D(n, 0.5) 1.83 and D(n,0.9) 4.40 µm, respectively.
Based on the results from the number distribution, the material is not considered to fall under the EC’s recommended definition of nanomaterial (50% < 100 nm based on particle number).

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
