(Z)-N-(3-aminopropyl)-N'-9-octadecenylpropane-1,3-diamine

Bioaccumulation: aquatic / sediment

Link to relevant study record(s)

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.
