Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 the Lead Registrant's basic copper carbonate show the following volume-rated particle size distribution: D(v,0.1) 4.43 µm; D (v,0.5) 16.2 µm; D(v,0.9) 33.7 µm. The corresponding number-based distribution is as follows: D(n,0.1) 0.271 µm; D (n,0.5) 0.397 µm; D(n,0.9) 0.748 µm. The material would not fall under the category of nanomaterial (50% < 0.1 µm, based on particle number). Joint registrants that produce or import basic copper carbonate corresponding to this specifiction are able to refer to the Lead Registrant's granulometry data for the purpose of REACH registration.
Additional information
The Lead Registrant produces basic copper carbonate with the following volume-rated particle size distribution: D(v, 0.1) 4.43, D(v,0.5) 16.2 and D(v,0.9) 33.7. Values for the number-rated distribution were determined to be D(n,0.1) 0.271, D(n, 0.5) 0.397, D(n,0.9) 0.748.
Based on the results from the number distribution, the material would not fall under the category of nanomaterial (50% < 0.1 µm, based on particle number).
Joint registrants that produce or import basic copper carbonate corresponding to this specifiction are able to refer to the Lead Registrant's granulometry data for the purpose of REACH registration.
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.
