Labdanum absolute

Other comments :

Cistus is a shrub about two meters high, with pink, red or white flowers depending on the variety.
Cistus harvesting on an industrial scale was first done in the region of Salamanca, and was then exported to the South of Spain, along Portugal, to Andalusia, vers the greatest cultures in Europe can be found.
Bases are obtained by deriving ciste-labdanum: Dynamone is obtained by cracking (breaking bonds of heavier molecules) and Ambrarome Absolute is obtained by pyrogenation among others.
The essential oil is more powerful, rising and terpenic but less ambered, warm and resinous than the absolute. The absolute is also cheaper than the essential oil.

Stability :

Solubility issues in perfumes
The terpenes identified in this raw material can polymerize when they are oxidized

Uses in perfumery :

Used in oriental, amber, spicy notes. Used in chypre perfumes. Can accompany floral notes, in small quantities, to enhance them.

Chemotypes :

The genus Cistus includes about 20 different species, the majority of which exudes fragrant gum.
Among these, the most used are:
Cistus ladaniferus var. albiflorus, var. maculatos, var. stenoiphyllus, which produce the resin used in perfumes.
Cistus creticus, with rose to purple petals, surronding a tuft of stamens.
Cistus salvifolius, with white petals.
Cistus parviflorus, with pale rose petals.

Extraction process :

In April, Cistus ladaniferus fields are covered with the famous white flowers, but they don't smell and are very delicate (they only last a few days). It is necessary to wait a few months, around May-June, for a new shoot to appear. This new branch protects itself from the sun - and from the summer heat of southern Spain - by secreting a very fragrant viscous gum. We use the latter in perfumery.
In July, from dawn to noon, new branches are cut with a sickle, bundled and taken to the factory to extract the gum. It will then be necessary to wait another 3 years to harvest the cistus again.
To obtain the resinoid, the gum is treated in a soda solution for extraction with a 3 to 5% yield. After filtration, an acid treatment is carried out. A pasty product is recovered by skimming and distilled to dry it. The paste is finally treated with alcohol, then filtered to remove insoluble compounds. A ''labdanum alcohol resinoid '' is then obtained.
Several reprocessing are possible on the cistus absolute, to remove insoluble compounds or colour. Such rectification has no olfactory impact.
