Where do resins come from?

If you’re interested in what resins mean to the modern world, you need to understand where they come from.

Amber (resinite) – harvested from fossilized coniferous trees

Balm of Gilead – a plant associated with resinous juices

Balsam – specific resins from trees or plants such as Dragon’s blood or galbanum

Canada balsam – turpentine made from the balsam fir tree

Boswellia – the tree is known for the frankincense resins

How are resins made?

One or multiple incisions are made in the tree bark to let resins out. Resins freely circulate within the tree and they cover the incision area to protect the tree from dryness.

Containers can be added to the trees to collect sticky or runny resins. But resins can also be left to harden before being collected, normally with a knife.

This is how resins become perfume ingredients

Resins pass through the distillation process to be concentrated in essential oils. Hot pressurized steam passes through the resins chamber prompting an evaporating process which is later turned to a condensation process where resins are collected as an essential oil.

Cold processing is another method of isolating resins and their mesmerizing smell. You can learn more about bergamot and why its volatile profile is mostly limited to cold processing techniques on fragrancespotter.
