Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
bioaccumulation in aquatic species: fish
Type of information:
(Q)SAR
Adequacy of study:
weight of evidence
Study period:
2010
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The procedures applied are according to the REACH guidance the most appropriate way of assessing the bioaccumulation potential of the specific substances under consideration.
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6
Principles of method if other than guideline:
EPIweb QSAR based on a measured Log Kow which is based on the ratio between the octanol solubililty and CMC.
GLP compliance:
no
Test organisms (species):
other: QSAR
Type:
BCF
Value:
3.16 dimensionless
Basis:
other: QSAR calculation
Conclusions:
The procedures applied are according to the REACH guidance the most appropriate way of assessing the bioaccumulation potential of the specific substances under consideration.
Executive summary:

Based on a measured log Kow of 3.4 a log BCF is calculated of 2.4 assuming no metabolism as a worst-case.

Description of key information

Based on a measured log Kow  of -0.3 a BCF is calculated of 3.162 L/kg ww

Key value for chemical safety assessment

BCF (aquatic species):
3.162 L/kg ww

Additional information

Based on a measured log Kow of -0.3 for both the Oleyltetramine and cocotriamine using the slow-stirring method (OECD 123) a BCF is calculated of 3.162 L/kg ww for polyamines.
