Application
(1) Propylene glycol is used as raw materials for resins, plasticizers, surfactants, emulsifiers and demulsifiers, as well as antifreeze and heat carriers.
(2) Propylene glycol is used as gas chromatography stationary liquid, solvent, antifreeze, plasticizer and dehydrating agent.
(3) Propylene glycol is mainly used for the extraction solvent of various spices, pigments, preservatives, vanilla bean, roasted coffee granule, natural flavor and so on. A moisturizing and softening agent for candy, bread, packaged meats, cheeses, etc.
(4) It can also be used as anti – mildew agent for noodle and filling core. Add 0.006% to soy milk, which can make the flavor unchanged when heating, and make white and glossy packaging bean curd.
