Description of key information

A Bioconcentration Factor was determined for Vinyl Neodecanoate based on a modified O.E.C.D. guideline 305 study conducted in rainbow  trout with exposure via dose-feed.  The dose-feed exposure route was used to overcome the poor water soulbility of Vinyl Neodecanoate.  The study was conducted with all appropriate analytical support and GLP compliance.  

Key value for chemical safety assessment

Additional information

A Bioconcentration Factor (BCF) of 1245 (1100 -1390) was calculated for Vinyl Neodecanoate in rainbow trout based on O.E.C.D. Testing Guideline 305 study with dose-feed modification. The dose-feed modification was necessary to overcome the poor water soulubility of Vinyl Neodecanoate. Vinyl Neodecanoate was rapidly cleared from fish tissue achieving 95% clearence within 14 days. All criteria for a valid study were met. Due to Vinyl Neodecanoates low water solubility the calculated BCF is a conservative estimation.
