Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Reference substance:
- Asphalt, sulfonated, sodium salt
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to the criteria in ECHA Guidance Chapter R.11 (PBT Assessment), SAS does not qualify as a PBT or vPvB. While SAS is not biodegradable and would be qualified as persistent under the criteria, it is not considered to have potential to be bioaccumulative, and, based on the low toxicity of acute tests to aquatic organisms, it is unlikely that SAS would pose a risk for chronic toxicity.
- Likely routes of exposure:
Persistence Assessment Summary: Sufficient information exists to evaluate the persistence of SAS in the environment (Section 4.1). Available data indicate that SAS is persistent in the environment according to criteria in Chapter R.11: PBT Assessment. The half-life of SAS in marine water, as predicted from tests performed with Soltex®Shale Inhibitor, is predicted to be greater than 60 days. Photodegradation and hydrolysis are not expected to be significant removal mechanisms.
Bioaccumulation Assessment Summary: Based upon the experimentally-determined octanol-water partition coefficients for SAS, as well as the high molecular weight and polarity of SAS constituents, the potential for bioconcentration and bioaccumulation of SAS in aquatic and benthic species is low. Predicted BCF values provide further support for this conclusion (Section 4.3). According to criteria in ECHA Guidance Chapter R.11: PBT Assessment, the BCF cut-off for indication of potential boaccumulation is a BCF >2000L/kg. Predicted BCFs for SAS are much lower than 2000 L/kg.
Toxicity Assessment Summary: Sufficient information exists to evaluate the acute toxicity of SAS to marine organisms (Section 7.1). Available data and QSAR modelling indicate that SAS has low acute and chronic toxicity to marine organisms (fish, invertebrates and algae). In addition, SAS is not considered to be Carcinogenic, Mutagenic or Reproductive toxicant (CMR).
