Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The concentration of charcoal Probe 4 (charcoal, coconut shell) in water was determined from the LOQ of total carbon (1.44 mg/L) and the total carbon (81.85%) of the test item (determined by elementary analysis) as: < 1.76 mg/L at 21.3°C.

Key value for chemical safety assessment

Water solubility:
1.76 mg/L
at the temperature of:
21.3 °C

Additional information

All samples showed good correspondence. All measurements at both flow rates lay below the limit of quantification (LOQ) of total carbon (TC) (1.44 mg/L C) and above the limit of detection (LOD) of the used carbon analyser of 0.357 mg/L.

The concentration of the test item was therefore calculated from the LOQ of TC and the carbon content of the test item (81.85%) as <1.76 mg/L at 21.3°C.

No observations arousing doubts concerning the accuracy of the results and the validity of the study were made.
