Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- Sodium dimehtyl 5 -sulphonatoisophthalate
(SIM-Ester) is not readily biodegradable and under environmentally
relevant conditions hydrolytically stable (t0.5 of 268 days at pH 7,
15°C). No simulation biodegradation tests are available to finally
conclude on the P/vP criterion.
The n-octanol/water partition coefficient (log Pow) was determined to be -2.86 (20°C) and the BCF was < 3. Thus, SIM-Ester is considered to be not B/vB. Sodium dimethyl 5 -sulphonatoisophthalate is not classified or likely to be classified as carcinogenic (cat. 1A or 1B), germ cell mutagenic (cat. 1A or 1B) or toxic to reproduction (cat. 1A,1B or 2) or STOT RE 1, or STOT RE 2 according to CLP. The EC50 values obtained in acute aquatic toxicity tests were above 0.1 mg/L. These data lead to the conclusion, that SIM-Ester does not fulfil the T criterion.
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.
