ALPHA AMYL CINNAMIC ALDEHYDE – floral, fruity and green note with hints of creamy jasmine, gardenia, tuberose, ripe peach and sweet herbs

Sweet, floral, oily, fruity, herbaceous, jasmine, tropical, and green with a powdery undertone. Reminiscent of apple, apricot, peach, and spices. A very soft, oily, and herbaceous scent, with light floral notes reminiscent of many natural flowers, but primarily jasmine, gardenia, and tuberose. It gives the perfume a jasmine-like floral note, combined with volatile floral compounds. It blends beautifully and helps fix the perfume (ACA is quite stable).
ACA is highly susceptible to oxidation if not properly treated with an antioxidant (traditionally added by most manufacturers). Old or oxidized ACA has a rancid, greasy odor. Lower-quality varieties of ACA may have a benzaldehyde, heptaldehyde, or amylonenal odor, sometimes called digheptenal.
It is one of the most common ingredients in perfumery. It provides a floral note similar to jasmine, combined with volatile floral chemical compounds. It blends perfectly and helps fix the perfume (ACA is quite stable). Concentrations in perfumery can range from 2% to 10%, and in exceptional cases up to 30-35%. It is used in many floral fragrances (jasmine, lily, lilac, lily of the valley, gardenia, magnolia, rose, tuberose, etc.), fruity compositions, aldehydic, chypre, fougère, powdery, citrus, and green.
