Description and usage notes:

A material of great power, best used in high dilution to give a boost to citrus ozonic and marine notes.  It lasts about 12 hours on a smelling strip with impact in a blend being highest in the top-notes but still noticeable in the heart of the fragrance. Often used alongside other high impact materials.

Manufactured by IFF it is described by them like this: “Odor: Intense aldehydic note with marine floral and citrus nuances. Very diffusive. Recommended uses: Fine fragrance, personal care, fabric care, home care, candles”.

Arcadi Boix Camps, writing in 1999 says that Floral Super and geraldehyde … are extremely strong aldehydes and, as usual in chemicals with this structure, have strong citrussy floral notes that combine very well with other aldehydes, especially aliphatic, but also with products such as 4-decenal.  I personally love these products and use them in small traces in all kinds of fragrances because they increase the power, radiance and elegance of them.He goes on to assert that they are “far better than the aliphatic aldehydes” but also that those aldehydes are improved by blending with products such as Floral Super and Geraldehyde.

Typical usage levels are from bare traces up to about 1% occasionally more for an ‘overdose’ effect.
