PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for alcohol ethoxylate (C16-20, < 2.5 EO) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2014).
Persistence
The substance is readily biodegradable in an OECD301B study.
Furthermore, all members of the category alcohol ethoxylates are readily biodegradable which is proved by several studies available for the certain mixtures. Due to the ready biodegradability of alcohol ethoxylates it is unlikely that the substances persist in the environment. Thus, the substance does not meet the screening criterion for persistency and is not considered to be persistent (P) or very persistent (vP).
Bioaccumulation
The substance has a measured log pow=3.4.
Furthermore, bioaccumulation in organisms is negligible, due to biotransformation and excretion of alcohol ethoxylates. Thus, the substance does not meet the screening criterion for bioaccumulation and is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
Toxicity
No long-term effects below the trigger value of 0.01 mg/L (EC10 or NOEC) occurred. Moreover, the substance is not classified according to Regulation (EC) No. 1272/2008 (8th ATP) as carcinogen, germ cell mutagenic or toxic for reproduction. Thus, the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the substance is not considered to meet the T criterion.
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.
