Appearance

Colorless or translucent crystalline mass or colorless, slightly viscous liquid forming crystals in the cold.

Solubility

Insoluble in water, soluble in alcohol, perfume oils and mineral oil.

Odor

Pleasant, dry-woody, Ambre-like and somewhat Orris-like odor of great tenacity and remarkable odor uniformity.

Uses in perfumery

This ketone, entirely a synthetic development and apparently not related chemically to a natural product, was brought on the American market in 1960 and has been used in soap perfumes and various cosmetic perfumes ever since. Its solid stability in soap and its performance apparently undisturbed by the influence of air and other normally detrimental factors have been its major assets besides of the Ambre-like character. It blends excellently with the Ionones and particularly with the Methylionones, Cedarwood derivatives, Vetiver products, aliphatic aldehydes, Cyclamal, Sandalwood, Oakmoss, etc. It forms an interesting base for ever-popular versions of the “Miss Dior” theme with Oakmoss, Galbanum and other dry, green or woody materials, also with Labdanum, many Carbinols, etc.

Production

Produced from 2,5-Dichloro-2,5-dimethyl-hexane plus Phenol in a Friedel-Craft’s reaction. Then hydrogenation to the alcohol followed by oxidation to the ketone (isomer mixture).
