Siam benzoin resinoid

Chemotypes :

The genus Styrax L. includes around 160 species, mostly found in Southeast Asia and South America.
Two types of benzoin resinoids are used in perfumery:
- Styrax tonkinensis (Pierre) Craib ex Hartwich : Benzoin resinoid, Siam
- Styrax benzoin Dryand., Benzoin resinoid, Sumatra
More widely used, Benzoin resinoid, Sumatra has a spicier and less vanillic scent profile compared to Siam.

Extraction process :

The benzoin producing trees are about 25 meters high and grow at more than 1500 meters altitude. Farmers start exploiting the trees when they reach the age of 8 for Siam and 25 for Sumatra, lasting about 10 years.
The gum-resin is obtained by a voluntary incision on the barks of the tree. This incision causes the exsudation of a milky resin which solidifies by oxidation when in contact with air. Harvesting is done by scratching the teardrops for a yield of 4 to 6 kg per tree per year.
Finally, the gums are extracted with organic solvent (ethanol) to obtain the resinoid by filtration after glazing (temperature gradient from 140 °F to 32 °F) the liquid.
It is very unusual to obtain an essential oil of benzoin by hydrodistillation.
The benzoin resinoid can be distilled to be bleached, without a great olfactory deterioration.

Uses in perfumery :

Used in oriental, vanilla, caramel, chocolate, exotic-ylang and tuberose notes for a warm and enveloping effect.
