Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Particle size distribution (Granulometry)
Administrative data
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Remarks:
- According to appendix R7-1 of ECHA Guidance on Information Requirements and Chemical Safety Assessment multiple techniques should be applied to investigate phys. chem. properties of particulates, although different measurement methods may not provide comparable results. Laser diffraction is the well experienced standard procedure for pigments to determine particle size distribution of the pigment as it is manufactured and delivered.

Any other information on results incl. tables
Given standard deviation is based on the general experience with the method and pigments. The estimated values are typical standard deviations for pigments:
D10: 4 % of D10 (minimum value 0.05 µm)
D50: 13 % of D50 (minimum value 0.1 µm)
D90: 29 % of D90 - D50
A monomodal particle size distribution was observed.
Applicant's summary and conclusion
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.
