Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 939-389-5 | CAS number: -
Bioaccumulation: aquatic / sediment
Administrative data
- Endpoint:
- bioaccumulation in aquatic species: fish
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3

Applicant's summary and conclusion
- Conclusions:
- In accordance with REACH Regulation 1907/2006, Annex IX (9.3.2), Column 2, a study of bioaccumulation need not be conducted if the substance has a low potential for bioaccumulation (based on a log Kow <=3. D-Glucopyranose, oligomeric, butyl glycosidehas a log Pow ≤ -0.91 and waiving of the data requirement is justified on the basis of the stated criterion.
- Executive summary:
In accordance with REACH Regulation 1907/2006, Annex IX (9.3.2), Column 2, a study of bioaccumulation need not be conducted if the substance has a low potential for bioaccumulation (based on a log Kow <=3. D-Glucopyranose, oligomeric, butyl glycosidehas a log Kow ≤ -0.91 and waiving of the data requirement is justified on the basis of the stated criterion.
The octanol-water partition coefficient of the substance was determined in the weight of evidence approach. The highest value (EU Method A.8, OECD Guideline 107 and OPPTS 830.7550 by using Rekker calculation method) was selected as worst case. A very similar result of -1.03 was obtained applying KOWWIN v1.68 (US EPA Episuite v4.1) to the monomeric constituent. For the dimeric constituent the calculation result is significantly lower (-3.52).The results are indicating a low potential for bioaccumulation and supporting the justification for waiving of the test requirement
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.
