| Hazard Information | Back Directory | [Chemical Properties]
Tetrahydro-pseudo-ionone has a sweet, floral, balsamic odor with a rose to woody quality. It has a sweet, fruity flavor, somewhat apple- and peach-like. | [Uses]
6,10-Dimethylundec-9-en-2-one finds some use in Rose
compositions, where its peculiar oily softness
lends very pleasant and natural notes, and
also supPorts mildly green notes in the composition. It blends furthermore excellently with
Vetiver and Labdanum, musks and Lavender
products, and it can justly be classified as a
very versatile perfume chemical. It is used in small amounts
in berry flavors, fruit complexes, etc. at the
rate of 1 to 15 ppm in the functional consumer
products. | [Definition]
ChEBI: 6,10-Dimethylundec-9-en-2-one is a monoterpenoid. | [Preparation]
By hydrogenation of pseudo-ionone with colloidal palladium; this reaction leads to a product with considerable mixture; also from linalool plus acetic anhydride and sodium ethoxide, followed by hydrogenation; another method starts with geraniol via the acid chloride. |
