Comment (FraterWork)
Hydroxycitronellal (since 1905) in its most radiant form is Cyclosia
[https://fraterworks.com/products/cyclosia]® (which we also stock) but its cost
puts it far out of budget for most perfumery projects. On the other hand, BASF
produces a spectacular quality at a price that fits most budgets. Luxury
fragrance houses frequently use the BASF version while Cyclosia® is relegated to
speciality use as a showpiece in much the same way as we now use other treasures
such as Rhodinol [https://fraterworks.com/products/rhodinol-ex-geranium-bourbon]
isolated from Bourbon Geranium and Geraniol ex Palmarosa
[https://fraterworks.com/products/geraniol-ex-palma-rosa].
Today, Hydroxycitronellal remains one of the few elegant lily of the valley
aldehydes that can be used in fairly generous amounts (up to 2.1% of the
finished perfume) whilst retaining IFRA 51 compliance.
Discovered around the same time as the orris / violet chemical Iralia

substantial part of the midcentury masterpiece Muguet des Bois

Usage
Average use (FraterWork)
4% in a perfume compound
Uses (FraterWork)
Essential for creating realistic lily of the valley, lilac, and other
"mute flower" accords; adds fresh floral character to soaps, personal care
products and fine fragrances.
Use (Hekserij)
Hydroxycitronellal has a fresh green scent that is especially reminiscent of
lily of the valley. The scent is not very strong, so it can be used undiluted.
Typical use is in green floral accords, but it can also be used in many blossom
scents and jasmine. You usually use between 0,1% and 10% of this substance in
the fragrance composition and in perfumes it is mainly a base note. It is an
aldehyde, yet also quite stable: can be used in soap.
IFRA 51 (FraterWork)
