710 Ready Mix is a proprietary blend of USP grade Propylene Glycol and a Natural Emulsifier used in the flavor industry. Ready Mix holds flavor and is more stable than anything on the market today! Ready Mix is used to transform solid herbal extract into a flavored tincture. NOTE: Separation may occur if concentrates contain heavy amounts of plant waxes, lipids and/or chlorophyll. Winterized products work best!
