Solvent extracts can be developed and prepared for proprietary use by individual clients. Examples include extracts done in water/glycerol, water/alcohol systems, alcohols, Propylene Glycol and Propylene Glycol Dicaprylate/Dicarprate, food grade oils, plus a variety of others. Your designated preservatives (such as paraben free) can be added during production. Solvent extracts can be refined to become essentially odorless. Inquires for other extraction systems and small lot production are invited.
