Phenylacetaldehyde 30ml 50% in PEA

Odour (decreasing): Floral-hyacinth, sweet, green-leafy, aldehydic. Powerful Main Synonyms: 2-phenylacetaldehyde; phenyl acetaldehyde; phenyl acetic aldehyde

Description –

Powerful floral aldehyde with distinctive hyacinth note and green aspects. Very versatile but can be unstable except when stabilised with a primary alcohol such as PEA, which is how it is supplied here. The PEA helps to further emphasise the floral aspect as well, increasing the distinction from the greener, less floral, but somewhat similar PADMA.

Usage -

Arctander says it is “widely used in Hyacinth, Lilac, Rose, Lily, Narcisse, Honey, Acacia, Sweet Pea, Cyclamen, Appleblossom (under protest from the author), and countless other fragrance types. In Rose bases it is often accompanied by its Dimethylacetal for emphasis on the earthy-green notes. The normal level of this aldehyde in a perfume oil is 1 to 2%, but it may vary considerably according to type, and to the accompanying materials. The main drawback in the use of this aldehyde is the fact that it is not very stable. Perfumes, made with a conspicuous amount of Phenyl acetaldehyde will, after one to three months of storage, show a very perceptible loss of odor power, and the aldehyde may no longer ‘stand out’. The fragrance type changes, and a customer may wonder why his new shipment smells so much ‘stronger’ than his 4-month-old stock of the same perfume. This is bound to happen in almost any perfume in which Phenylacetaldehyde is a conspicuous component. It is adviseable to use the aldehyde at such (low) concentration that the inevitable change is less perceptible, and also not to keep stock of perfumes in which the aldehyde occurs at relatively high concentration.”

Limitation of Use by IFRA - Note that if you are complying with the IFRA guidelines you’ll need to stick to much lower levels than Arctander is suggesting because it is restricted to 0.3% of the finished product for alcoholic fine fragrances: more detail is in the table below, using the standard IFRA product categories.
