Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
The PBT Assessment for D-Glucopyranose, oligomeric, C10-16-alkyl glycosides, carboxymethyl ethers, sodium salts (CAS 383178-66-3) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2012d).
Persistence
D-Glucopyranose, oligomeric, C10-16-alkyl glycosides, carboxymethyl ethers, sodium salts is readily biodegradable in one study according to OECD 301B (67.9% (O2 consumption) after 28 d). Thus, the test substance does not meet the screening criterion for persistence and it is not considered to be P or vP.
Bioaccumulation
Based on the experimental 1-octanol/water partition coefficient of - 1.7, accumulation of the substance in organisms is not to be expected. Thus the substance is not considered to be B or vB.
Toxicity
The long-term toxicity of the substance is > 0.01 mg/L. The substance is not classified for specific target organ toxicity, carcinogenicity, mutagenicity or reproductive and developmental toxicity in mammals (see section 5.9). The criteria for “T” based on mammalian effects are therefore not met. Thus, the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the substance is considered to be not T.
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.
