ABSOLUTES: A Simple Definition

Absolutes are fragrance materials that have been extracted from concrete using ethanol alcohol.

They are highly concentrated fragrance materials. They are also completely dissolvable in ethanol alcohol. It's normally a liquid material or it can sometimes be a semi-liquid or a wax, depending on what the material is like. Beeswax can be a little more waxy. Clary sage, for example, is a semi-solid.

You've got an acacia absolute that is very waxy, it actually looks like a wax. There are some particular types of material that cannot be distilled. They have to be extracted into an absolute.

It has to be done through cold distillation (usually Hexan is used as a solvent).

Cold distillation is able to pull the odorous material out of delicate things, like petals, until it's exhausted, and when solvent is removed, concrete is created.

The ethanol alcohol is then added to the concrete which will dissolve the concrete.

The next step is filtration, when the dissolved wax or fatty material gets separated from the alcohol into the alcohol and the odorous material. After the filtration alcohol will evaporate by vacuum pressure, and what's left is the absolute.
