China High Quality D-Biotin Factory - Mono Propylene Glycol – COLORKEM Detail:
Products Description
It is a colorless liquid with steady viscosity and good water absorption.
It is nearly odorless, uninflammable and minutely toxic. Its molecular mass is 76.09. Its viscosity (20oC), specific heat capacity (20oC) and latent heat of vaporization (101.3kpa) are respectively 60.5mpa.s, 2.49KJ/(kg. oC) and 711KJ/kg.
It can be mixed and solved with alcohol, water and various organic agents.
Propylene Glycol is the raw material for preparing unsaturated polyester resin, plasticizer, surface active agent, emulsifying agent and demulsifying agent.
It can also be used as mould inhibitor, antiseptic for fruit, ice inhibitor and moisture preserving agent for tobacco.

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.
