Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Criteria for assessing PBT properties are defined in Annex XIII, REACH Regulation (EC) No. 1907/2006. Further details are laid down in ECHA Guidance on Information Requirements and Chemical Safety Assessment; Chapter R.11: PBT Assessment (May 2008). The PBT or vPvB assessment should be based on assessments for each parameter (i.e. P or vP, B or vB and T). Substances are only assigned as PBT or vPvB when they fulfill the criteria for all three properties persistency, bioaccumulation and toxicity (i.e. PBT substance) or both criteria (very persistent and very bioaccumulative) in case of vPvB.
Beyond question, Diphenyl methylphosphonate (DPP) is considered as persistent (P), but not very persistent (not vP) based on available data. The B criterion (bioaccumulative substance) is certainly not fulfilled, based on the experimentally determined logPow far below the trigger value of 4.5 and the predicted Bioconcentration Factor (BCF) far below 100. Based on available data concerning the aquatic chronic toxicity for freshwater organisms, the T criterion is not fulfilled. Furthermore, DPP is not classified as carcinogenic, germ cell mutagenic, STOT RE category 1 or 2 or toxic for reproduction according to Regulation (EC) No 1272/2008.
As conclusion, Diphenyl methylphosphonate (DPP) does not fulfill all relevant criteria for a PBT nor for a vPvB-substance, respectively.
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.
