Product Description

99.8% Min C3H8O2 Best Price High Purity CAS NO. 57-55-6 Propylene Glycol Food Grade

 

Propylene glycol is in the production of unsaturated polyester resins that, in turn, go into items that effect our daily lives, like water tanks, or our leisure time, like sailing boats. It can also be used as plasticizer, surface active agent, emulsifying agent and demulsifying agent, mould inhibitor, antiseptic for fruit, ice inhibitor and moisture preserving agent for tobacco.

Introduction

PG 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.
