Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
The QMRF and QPRF documents are attached to "Background information".
Qualifier:
according to guideline
Guideline:
other: REACH guidance on QSARs, R.6, May 2008
Principles of method if other than guideline:
QSAR based on partiotioning between fat and water.
GLP compliance:
no
Type:
BCF
Value:
ca. 70 L/kg
Remarks on result:
other: QSAR calculation (BCFBAF v3.01)
Details on results:
See attached QPRF and QMRF files.
Validity criteria fulfilled:
yes
Remarks:
Ethylhexyl-(S)-lactate is considered to be within the applicability domain of the BCFBAF v3.01 model.
Conclusions:
With a bioconcentration factor for fish of approximately 70 (estimated by QSAR), ethylhexyl-(S)-lactate is not liable to bioconcentrate.
Executive summary:

With a bioconcentration factor for fish of approximately 70 (estimated by QSAR), ethylhexyl-(S)-lactate is not liable to bioconcentrate.

Description of key information

The QSAR calculated BCF for fish of 70 suggests that 2-ethylhexyl-S-lactate exhibits only a minor bioaccumulation potential.

Key value for chemical safety assessment

BCF (aquatic species):
70 L/kg ww

Additional information

2-ethylhexyl-S-lactate is not liable to bioaccumulate.
