Альфа-амилциннамальдегид

Описание

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.

Химические свойства

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.

Вхождение

Reported found in black tea and soybean

Использование

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.

Подготовка

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.

Общее описание

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

Контактные аллергены

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.

Профиль безопасности

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

Метаболизм

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).
