RHODINYL ACETATE Usage And Synthesis

Chemical Properties

Rhodinyl acetate has a characteristic,fresh,rose-like odor.It has an analogoustaste on dilution, bitter when concentrated.

Chemical Properties

Colorless to slightly yellow liquid; rose- like odor. Solu- ble in alcohol and mineral oil; insoluble in glycerol. Combustible.

Occurrence

Found in geranium oil.

Uses

Perfumery, flavoring agent.

Preparation

By acetylation of rhodinol from geranium oil.

Definition

A mixture of terpene alcohol acetates consisting primarily of l-citronellyl acetate.

Application

Rhodinyl acetate, which represents the mixed acetates of the alcohols available in the commercial product known as Rhodinol (from Geranium oil), is used in perfume compositions, mostly in luxury perfumes. It lends very attractive top- and middle-notes to Muguet, Carnation, Gardenia, Freesia, Rose, etc., and it blends well with Citrus oils, Ionones, fruity and green odours, etc. It is often used in better lipstick perfumes. Rhodinyl acetate is used in flavour compositions in discrete amounts for sweet berry types, such as strawberry and raspberry, and in honey, rose, apricot, and coconut imitations. Its use in the old-fashioned "Sen-Sen" type or "Cachou" type fragrance is well known and occasionally transferred to new versions of floral dentifrice flavours; it is sweeter than Geranium oil but tends to perform very "perfumey" at levels higher than 10 or 20 ppm, particularly in combination with Ionones and Patchouli (“Sen-Sen"-types, etc.). Normal concentration is from 1 to 20 ppm in the finished product.

Safety Profile

Low toxicity by ingestion and skin contact. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
