Why CO2 essential oil extraction?

The process is purer.

Essential oils smell better.

It's better for the environment.

Can I have a CO2 essential oil extraction equipment setup at home?

The winterization process then removes undesirable materials creating a fine, clear oil:
  • Mix the extract thoroughly on a hot plate with ethanol (200 proof). 
  • Place the mixture into a deep freezer for at least 24 hours (note: the longer it’s kept in, the easier it is to separate). 
  • For the separation process you will need a filter, funnel, and flask.
  • As the ethanol/extract mixture flows through the filter into the flask, fats, waxes, and lipids are left behind.  
  • Remove the ethanol that was used in the first step by warming the mixture in a rotary evaporator.
  • In addition to winterizing oil, it can be further refined using short path steam distillation or thin film equipment.
