Lots of reasons. According to OSHA, Pentane is non toxic at realativly high concentrations. It boils at 97° F, which preserves the various oils being extracted. Because Pentane boils at such a low tempeture, hot and cold water is all that is required to recover Pentane from extraction tinctures.
A few do, most don't. Please stay away from the systems that do not. The OilXGreen is the worlds least expensive closed loop oil extraction system.
Just about any organic material that contains oil can be concentrated with Pentane!
Depends on source material. We usally soak for an hour or two and obtain 90% or so of the targeted oil. Depending on the value of the source material, a second soak might be justified.
Nope! Any refrigerator will do.
Yes. The 316 Stainless Steel Alloy we use is approved for food and medical applications. The gaskets we use are made of FDA Grade Nitrile. The Mason Jars are of course safe for food.
Other than the glass, FOREVER.
Other than Pentane, Hot Water, Ice, and source material everything you need to start extracting essential oils is included in the OilXGreen kit.
