Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Name:
- Reaction mass of 4-sulphophthalic acid and 3-sulphophthalic acid
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: bulk
- Reference substance:
- Reaction mass of 4-sulphophthalic acid and 3-sulphophthalic acid
- Reference substance:
- Reaction mass of 4-sulphophthalic acid and 3-sulphophthalic acid
- PBT status:
- the substance is not PBT / vPvB
- Justification:
There are no biodegradation studies on the reaction mass of 4 -sulphophthalic acid and 3 -sulphophthalic acid (read across target substance) and biodegradation information was read across to the reaction mass of 1,2-Benzenedicarboxylic acid, 4-sulfo-, trisodium salt, 1,2-Benzenedicarboxylic acid, 3-sulfo-, sodium salt (1:3), sodium sulphate (read across source substance). The sulphophthalic acid sodium salt reaction mass was 90 -100% biodegradable after 28-days in the DOC Die-Away Test. Based on the determined rate of biodegradation at the end of exposure the test substance can be evaluated as readily biodegradable.
Reference
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.
