solvent extraction

binomial name: solvent extraction
when steam and heat are too abrasive for delicate plants, a chemical solvent is used to extract the fragrant material to make essential oils. the method involves covering the plant material with a solvent to dissolve them into one solution. this mixture containing both the chemical solvent and dissolved plant material is then filtered and distilled using low pressure. the result is a waxy substance called the concentrate. this type of extraction produces three different products: the concentrate, an absolute and a botanical wax, all of which are used in cosmetics and perfumery. this method delivers a finer fragrance than that of other distillation processes.

benefit: this method delivers a finer fragrance than that of other distillation processes.
