alpha-Amylcinnamaldehyde

Description

Amylcinnamic aldehyde is an oxidation product of amylcinnamic alcohol, one component of the "fragrance mix" and can be found as a sensitizer in cases of contact dermatitis in bakers.

Chemical properties

Light yellow transparent liquid

Chemical properties

alpha-Amylcinnamaldehyde has been identified as an aroma volatile of black tea. It is a light yellow liquid with a floral, slightly fatty odor, which becomes reminiscent of jasmine when diluted.The aldehyde is relatively unstable and must be stabilized by antioxidants.
It is prepared from benzaldehyde and heptanal in the same way as cinnamaldehyde.
??-Amylcinnamaldehyde is a very popular fragrance substance for creating jasmine notes. It is stable to alkali and long-lasting; large quantities are used, particularly in soap perfumes.

Chemical properties

α-Amylcinnamaldehyde has a distinct floral (jasmine, lily) note.

Occurrence

Reported found in black tea and soybean

The Uses of alpha-Amylcinnamaldehyde

amyl cinnamal is used as a fragrance. Although it is naturally occurring in some plants, it is most often synthetically derived when used in cosmetic products.

The Uses of alpha-Amylcinnamaldehyde

Amylcinnamaldehyde is a flavoring agent that is a yellow liquid with an odor similar to jasmine. It is insoluble in glycerin and propylene, soluble in fixed oils and mineral oil. It is obtained by chemical synthesis. It can be used alone or in combination with other flavoring substances or adjuvants. It is also termed amylcinnomaldehyde.

The Uses of alpha-Amylcinnamaldehyde

Raw material in the production of perfumes; some perfumery uses (tuberose; peach; cherry; Estee; honeysuckle Chevrefeuille) Cross: amylcinnamic alcohol. AMYL CINNAMAL

Background

alpha-Amyl cinnamaldehyde has a jasmine-like odor and is a widely used synthetic fragrance & suspected allergen. It is used in allergenic testing.

Indications

alpha-Amyl cinnamaldehyde is used in allergenic testing.

Preparation

By condensation of n-amyl aldehyde with cinnamic aldehyde. This method of condensation of aromatic aldehydes with aliphatic aldehydes has the maximum yield in α-amylcinnamic aldehyde with little formation of the inferior homologs. The methyl, ethyl and propyl amylcinnamic aldehyde analogs exhibit a characteristic scent.

Definition

ChEBI: Alpha-Amylcinnamaldehyde is a member of cinnamaldehydes.

Taste threshold values

Taste characteristics at 40 ppm: sweet, floral, spice-like with cinnamic and waxy nuance

General Description

The short-term feeding studies in rats was carried out using α-amylcinnamaldehyde, a flavouring matter.

Flammability and Explosibility

Not classified

Contact allergens

a-Amyl-cinnamic aldehyde is an oxidation product of amylcinnamic alcohol, a sensitizing fragrance, and one component of the “fragrance mix.” It can also be a sensitizer in bakers. It has to be mentioned by name in cosmetics within the EU.

Safety Profile

Moderately toxic by ingestion. A severe skin irritant. See also ALDEHYDES. When heated to decomposition it emits acrid smoke and irritating fumes.

Metabolism

Not Available

Metabolism

So far as is known, all aromatic aldehydes are metabolized in the animal body by oxidation to the corresponding acids. In some instances, the aldehydes are excreted as glucuronides. Cinnamic aldehyde is oxidized to cinnamic acid which is then degraded to benzoic acid, but ethyl cinnamic aldehyde is oxidized to the corresponding acid and is not further metabolized(Williams, 1959).
