Administrative data

PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

The PBT Assessment for D-Glucopyranose, oligomeric, undecyl glycoside (CAS 98283-67-1) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2012).

 

Persistence

Screening criteria:

D-Glucopyranose, oligomeric, undecyl glycoside (CAS 98283-67-1) is readily biodegradable in a study according to OECD 301 F (85% based on ThOD(NH4) after 28 d). Thus, the substance does not meet the screening criterion for persistence and is not considered to be persistent (P) or very persistent (vP).

 

Bioaccumulation

Screening criteria:

D-Glucopyranose, oligomeric, undecyl glycoside (CAS 98283-67-1) has a log Kow of – 2.58 to 2.41 (EPI Suite v3.20 KOWWIN v1.67). Thus, the substance does not meet the screening criterion for bioaccumulation and is not considered to be bioaccumulative (B) or very bioaccumulative (vB).

 

Toxicity

Long-term toxicity testing with Daphnia magna resulted in an EC10 of 1.76 mg a.i./L (OECD 202 part II; read-across from CAS 110615-47-9). Moreover, the substance is not classified according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 (6th ATP). Thus, the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the test substance is not considered to meet the T criterion.
