Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

PNECs were derived for freshwater, saltwater, sediment, and soil using either experimental results or equilibrium partitioning calculations. The PNECS derived using experimental data were based on Klimisch 1 or 2 studies because these studies took into account the physico-chemical properties of vinyl acetate and therefore were conducted in closed systems with no or minimal headspace to avoid loss of the test material and ensure a consistent exposure of the organisms. Other studies were available but did not meet the quality criteria and therefore these were not used in the PNEC derivation.

 

QSARs (based on the ecosar class vinyl/allyl esters) were generated using EPI suite, in order to support the use of lower assessment factors for derivation of the PNECs. The QSARs generated reinforce that fish are the most sensitive trophic level.

Conclusion on classification

Based on the criteria of Regulation (EC) No 1272/2008, vinyl acetate has to be classified as “Chronic aquatic toxicity, category 3”, hazard statement H412 “Harmful to aquatic life with long-lasting effects".
