Description of key information

Flammability testing was waived. Modified Small Vinyl Ester is not flammable in contact with water, neither has it pyrophoric properties in contact with air. Modified Small Vinyl Ester does not contain chemical functional groups that might lead to spontaneous ignition in air and/or evolution of flammable gases in contact with water. Handling in the laboratory in connection with performance of other physico-chemical tests, including dissolution in water did not lead to any spontaneous reactions. 

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Modified Small Vinyl Ester does not contain chemical functional groups that might lead to spontaneous ignition of the substance in contact with water and/or to the evolution of a flammable gas, cf. Bretherick's Handbook of Reactive Chemical Hazards. Modified Small Vinyl Ester is only slightly soluble in water. In connection with determination of other physico-chemical properties, Modified Small Vinyl Ester was handled and dissolved (saturated solutions) in water without any spontaneous reactions. This demonstrates that Modified Small Vinyl Ester does not ignite spontaneously in contact with air or water. It is evaluated that Modified Small Vinyl Ester is non flammable.

 

Modified Small Vinyl Ester does not contain chemical functional groups that might lead to ignition of Modified Small Vinyl Ester in contact with air. Furthermore, Modified Small Vinyl Ester was handled under normal laboratory conditions during the determination of other physico-chemical properties. This demonstrates that Modified Small Vinyl Ester will not ignite in contact with air. Therefore, it cannot be characterized as pyrophoric.

Justification for classification or non-classification

In connection with determination of other physico-chemical properties, Modified Small Vinyl Ester was dissolved (saturated solutions) in water and it was handled under normal laboratory conditions without any spontaneous reactions. This render probable that Modified Small Vinyl Ester will not ignite in contact with air or water.
