The Growth Technology IsoPropyl Alcohol (IPA) is designed for oil extraction from herbs, and has a purity of 99.9%. It can also be used in the process of making Hand Sanitizer.

GT Iso Propyl Alcohol is the replacement product for Organic Oil Extraction Liquid which is no longer available in Australia.

Commercially, essential oils are made in a two step solvent extraction process. In the first step, hexane or supercritical carbon dioxideis used to extract oils into a product known as a “concrete”. This contains the concentrated extract full of the waxes and fats, as well as the fragrant material from the plant. The concrete is then mixed with another solvent such as ethanol, which serves to extract the aroma and oils of the material. This product is known as an absolute.

Solvent extraction is used for jasmine, tuberose, carnation, gardenia, jonquil, violet leaf, narcissus, mimosa, rose and other delicate flowers. Absolutes made via solvent extraction have an extremely low concentration of solvent residue, approximately 5 to 10ppm. Absolutes have therapeutic value and are often used for psychological purposes and for animals, particularly horses. Many therapists use absolutes, such as rose absolute, jasmine, and tuberose, as a part of their aromatherapy.
