Description of key information

In contact with water the substance will hydrolyse slowly.

Key value for chemical safety assessment

Additional information

There is one study availbale regarding hydrolysis of 1,4-bis[(ethenyloxy)methyl]cyclohexane in water according to EU method C.7 (Life Science Research 1991). At pH 4 and 50°C more than 50% of the test substance hydrolised in less than 2.4 h. Applying a factor of 10, one can extrapolate to the half-life at 25°C. Hence at pH 4 and 25°C the half-life should be less than 24 hours. At pH 7 and 25°C a half-life of 27.3 hours was measured while at pH 9 and 25 °C a half-life of 80.3 days was found. The products of hydrolysis were not measured. Due to the molecular structure, the cleavage will occur at the ether bonds to form acetaldehyde and 1-Cyclohexandiol-4 -vinylther and, aftter total hydrolysis 1,4 -Cyclohexandiol.

Due to the fact that all studies on acute toxicity on aquatic organisms were performed at pH- values of 7 or higher, hydrolysis is of no concern.
