| | alpha-Hexylcinnamaldehyde Usage And Synthesis |
| Description | α-Hexylcinnamaldehyde has a jasmine-like odor, particularly on
dilution. May be synthesized by condensation of octylaldehyde
with benzaldehyde. | | Chemical Properties | Hexyl cinnamaldehyde has a jasmine-like odor, particularly on dilution. | | Chemical Properties | Pale-yellow liquid; jasminelike odor,
particularly on dilution. Soluble in most fixed
oils and in mineral oil; insoluble in glycerol and in
propylene glycol. | | Chemical Properties | alpha-Hexylcinnamaldehyde is a yellow liquid
with a mild, slightly fatty, floral, somewhat herbal odor, and a distinct jasmine
note. Similarly to the -amyl homolog, -hexylcinnamaldehydemust be protected
against oxidation by the addition of stabilizers. It is prepared in a manner similar
to that of -amylcinnamaldehyde by alkaline condensation of excess benzaldehyde
with octanal (instead of heptanal). -Hexylcinnamaldehyde is widely used
in flower compositions (e.g., jasmine and gardenia) and, because of its stability to
alkali, in soap perfumes. | | Occurrence | Reported found in cooked, scented rice. | | Uses | hexyl cinnamal is also known as hexyl cinnamic aldehyde. It is a fragrance that provides a floral, jasmine-like scent. | | Uses | α-Hexylcinnamaldehyde is characterized by a typical floral scent, which makes them suitable to be used as fragrances in personal care (perfumes, creams, shampoos, etc.) and household products. It has been also used as flavouring additive in food and pharmaceutical industry. | | Definition | ChEBI: A member of the class of cinnamaldehydes carrying a hexyl substituent at the alpha-position. | | Preparation | By condensation of octylaldehyde with benzaldehyde | | Taste threshold values | Taste characteristics at 5 ppm: sweet, waxy, floral, green, citrus and fruity nuances | | General Description | Solubilization of α-hexylcinnamaldehyde by the ionic surfactants, sodium dodecyl sulfate and dodecyltrimethylammonium chloride and a non-ionic surfactant such as dodecyl polyoxyethylene ethers has been investigated. | | Hazard | Combustible. | | Contact allergens | Hexyl cinnamic aldehyde is a fragrance allergen. Its
presence has to be mentioned by name in cosmetics
within the EU. | | Solubility in organics | Insoluble in Propylene glycol and Glycerin. Soluble in alcohol, miscible with oils.
