When put under pressure at a temperature below 40o C, CO2 enters a supercritical, fluid state. It assumes the properties of a solvent but has the fluidity of a gaseous substance.

Indeeed, these extracts do not contain any solvents and have not been processed at the usual high temperatures. This is truly a ,SOFT EXTRACTION method.
