Ethanedial
Last updated: 20/08/2023
(Also known as: glyoxal; glyoxime; ethanedione; biformal; oxaldehyde)
Ethandial is an ethylene releasing plant growth regulator. It is miscible with water. Data relating to the environmental fate of ethanedial is not relevant. It tends to have a low toxicity to biodiversity. Ethanedial is moderately toxic to mammals via the oral route and is an irritant.
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
