2,6-Dimethyl octanal is a food additive permitted for direct addition to food for human consumption as a synthetic flavoring substance and adjuvant in accordance with the following conditions: 1) the quantity added to food does not exceed the amount reasonably required to accomplish its intended physical, nutritive, or other technical effect in food, and 2) when intended for use in or on food it is of appropriate food grade and is prepared and handled as a food ingredient.

ISODECALDEHYDE is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.

Aldehydes are readily oxidized to organic acids, which, in turn, can serve as substrates for fatty acid oxidation pathways and the Krebs cycle. ... Oxidation of aldehydes is catalyzed by aldehyde dehydrogenase, which has been found in the brain, erythrocytes, liver, kidney, heart, and placenta. /Aldehydes/

... The detoxification of aldehydes can be seen to proceed basically via two routes: (1) an oxidation to yield readily metabolized acids; (2) inactivation by reaction with sulfhydryl groups, particularly glutathione. Under conditions that either deplete glutathione levels, or that result in an inhibition of aldehyde dehydrogenase (for example, Antabuse treatment), the acute and chronic effects of aldehyde toxicity might be more fully expressed. /Aldehydes/
