Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to regulation (EC) 1907/2006 (REACH) a PBT and vPvB assessment shall usually be conducted as foreseen in Article 14 (3) (d) in conjunction with Annex I Section 4 and according to the criteria laid down in Annex XIII. However, according to R11 « Guidance on information requirements and chemical safety assessment Chapter R.11: PBT Assessment » and theAnnex XIII, the PBT and vPvB criteria of Annex XIII to the Regulation do not apply to inorganic substances.
Furthermore the two points must be taken in consideration for the PBT an vPvB assessment:
- Based on all the relevant data on hydrolysis and decomposition in water and based on the T1/2 value of 10 hours, the substance is considered as not persistent in surface water and although no adsorption/desorption test was performed due to technical difficulties (instability of the substance and difficulty in assessing results), the substance is considered as not persistent in sediments.
- Bioaccumulation is not considered a relevant endpoint for monochloramine as it is an inorganic substance, which is soluble in water, used in an aqueous solution at low concentrations in water treatment and thus highly diluted when entering the aquatic environment. Furthermore hydrolysis (T1/2= 10h) and/or degradation (T1/2dependent on factors such as pH, T, light conditions) of monochloramine in the aquatic environment, will limit the amount of bioavailable monochloramine.
Considering the above, Monochloramine is neither PBT nor vPvB.
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.
