Chemical Properties

1,1-Dimethoxydecane is a colorless liquid. Almost insoluble in water, soluble in alcohol and oils. It has a characteristic, herbaceous, green, citrus-floral odor and a brandy, cognac flavor.

Uses

Finds some use in perfume compositions, mainly in heavy floral bases, Gardenia, Cassie, Tuberose, etc. and occasionally in Citrusy topnotes as a modifier for the Aldehydes. Its odor is overall more refreshing than that of the parent aldehyde.

Uses

1,1-Dimethoxydecane is an aroma compound of fresh blackberries and is used in citrus oils.

Preparation

From decanal and methyl alcohol.

Definition

ChEBI: 1,1-Dimethoxydecane is an acetal.

Taste threshold values

Taste characteristics at 2 ppm: fatty, waxy, citrus orange with fatty aldehydic nuances and a hint of mushroom.

Safety Profile

A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes
