Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
GCS-11-T proved to be readily biodegradable under aerobic conditions. In a BOD study conducted according to OECD Guideline 301 guidelines, the substance was readily biodegraded to >/= 80% within an incubation period of 28 d; the validity criteria of OECD Guideline were fulfilled. Based on the physical chemical properties (water solubility, log Pow) and the ready biodegradability any significant bioaccumulation of the test substance is not to be expected.
Relevant and reliable results from acute toxicity testing of the test item itself are not available. However, relevant data determined for strucurally closely related chemicals are available. As for the latter compounds higher water solubility was found than for the test item it can be assumed that their aquatic effect values can be regarded in the sense of worst-case for the assessment of the test item due to their expected better bioavailability for exposed test organisms.
Based on the available data, algae proved to be, by far, the most sensitive organism (Pseudokirchneriella subcapitata: inhibition of growth rate: 72 h ErC50=15.41 mg test item dry matter/L nominal). In addition long-term toxicity data on algae are also available (NOEC=3.13 mg dry matter/L nominal) but this result should not be taken into account if not supported by results of at least another trophic level. In consequence of the data, the test item is not to be classified according to Commission regulation (EU) No. 286/2011. Considering all available toxicity data, the test item is not to be regarded as a substance exhibiting PBT or vPvB properties.
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).
