Toxicity Summary
Link to the Distributed Structure-Searchable Toxicity (DSSTox) Database
IDENTIFICATION AND USE: Decaldehyde (Decanal) is a colorless to light-yellow liquid. The main use of decanal is for citrus tones and for the manufacture of synthetic citrus oils. In addition, the C10 aldehydes have value as intermediates in the synthesis of pharmaceuticals and in the polymer and pesticide fields. In the aircraft cabin, decanal was produced in the presence of ozone from surface reactions with occupants and their clothing, consistent with the inference that occupants were responsible for the removal of >55% of the ozone in the aircraft cabin.
HUMAN EXPOSURE AND TOXICITY: Decanal was cytotoxic to Hela cells with IC50 less than 20 ug/mL.
ANIMAL STUDIES: Decanal demonstrated antifungal and bactericidal properties.
ECOTOXICITY STUDIES: Decanal did not significantly affect survival or hatching success of the brine shrimp Artemia salina.
