Chemische Eigenschaften
CLEAR COLORLESS TO PALE YELLOW LIQUID
Chemische Eigenschaften
Phenethyl acetate has a floral odor reminiscent of rose with a honey-like undertone and a sweet, fruit-like taste reminiscent of raspberry.
Chemische Eigenschaften
Phenethyl acetate occurs in a number of essential oils and is a volatile aroma component of many fruits and alcoholic beverages. Phenylethyl acetate is a colorless liquid with a fine rose scent and a secondary, sweet, honey note. It is used in perfumery as a modifier of phenylethyl alcohol, for example, in rose and lilac compositions. In addition, it is used in a large number of aromas, in keeping with its natural occurrence.
Occurrence
Reported found in apple, banana, currants, guava, grapes, pineapple, tomato, strawberry, melon, cinnamon, cassia leaf, clove bud, peppermint oil, vinegar, breads, cheeses, butter, beer, cognac, whiskies, cider, sherry, grape vines, tea, Arctic bramble, olive, passion fruit, plum, mushroom, starfruit, Bantu beer, mango, fermented radish, litchi, wort, Bourbon vanilla, brandy, naranjilla fruit, lamb’s lettuce and eucalyptus oil.
Verwenden
2-Phenethyl acetate is a highly valued natural volatile ester with a rose-like odour and is widely used to add scent or flavour to cosmetics, soaps, foods and drinks.
Verwenden
Phenylethyl acetate mantains the typical rose notes of Phenylethanol with a more intense honey profile which is perfect for fruit and alcoholic drink applications. It is used as a pharmaceutical intermediate and also it holds application in gas chromatography and liquid chromatography.
Definition
ChEBI: The acetate ester of 2-phenylethanol.
synthetische
By acetylation of phenylethyl alcohol.
Aroma threshold values
Detection: 3 to 5 ppm
Taste threshold values
Taste characteristics at 50 ppm: fruity, sweet, honey, floral, tropical, rosy with a slight yeasty, honey note with a cocoa and balsamic nuance.
