Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Study period:
October 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
EDTA-CoK2 is produced by the same process as EDTA-CoNa2. Thus it can be assumed that due to the structural similarity the particle size is comparable.
Reason / purpose for cross-reference:
read-across source
Qualifier:
according to guideline
Guideline:
OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions - Method A: Particle Size Distribution (effective hydrodynamic radius)
Type of method:
Laser scattering/diffraction
Key result
Percentile:
D50
Mean:
549 µm
St. dev.:
12
Conclusions:
The test item EDTA-CoNa2 has a median particle size D50 = 549 µm, which was determined by laser diffraction measurement. As EDTA-CoK2 is produced by the same process, it can be assumed that due to the structural similarity the particle size is comparable.
