Authentic guarantee Dow DOW pharmaceutical grade food grade propylene glycol Dow

Propylene glycol, propylene glycol, also known as. With water, ethanol and various organic solvents. Propylene glycol can be used as the raw material of unsaturated polyester resins in cosmetics, toothpaste and soap with glycerin or sorbitol is used as a wetting agent with. The humidity is used in hair dye, even hair agent, also used as an antifreeze, is also used cellophane, plasticizers and pharmaceutical industries. Chinese name: Propylene glycol English name: 1,2-propanediol, propylene glycol Chinese alias: propylene glycol CAS Number: 57-55-6 Formula: C3H8O2 Molecular Weight: 92.0938 Melting point: -6.5 ℃ Boiling point: 245 ℃ Density: relative density (water = 1) 1.04 Appearance: colorless, viscous liquid absorbent stable, almost odorless vapor pressure: 106Pa / 20 ℃ Flash point: 99 ℃ (closed cup), 107 ℃ (open cup) heat capacity: (20 ℃ ) 2.49kJ / (kg ℃) heat of vaporization:. (101.3kpa) 711kJ / kg auto-ignition temperature: 421.1 ℃ Viscosity: (20 ℃) ??60.5mpa.s Solubility: with water, ethanol and various organic solvents Main purposes : Propylene glycol is an unsaturated polyester, an important raw material epoxy resin, polyurethane resin, the amount in this area accounted for about 45% of the total consumption of propylene glycol, which is used extensively for unsaturated polyester surface coatings and reinforced plastics. Propylene glycol viscosity and good moisture absorption, and non-toxic, and thus in the food, pharmaceutical and cosmetic industry is widely used as a hygroscopic agent, antifreeze, lubricants and solvents. In the food industry, propylene glycol and propylene glycol fatty acid esters of fatty acid reaction, mainly for food emulsifier; Propylene glycol is a good solvent seasoning and pigment. Propylene glycol used in the pharmaceutical industry for the manufacture of various types of ointment, ointment solvent, softener and excipients, etc., because of propylene glycol with various spices has good mutual solubility, which is also used as a solvent and emollient cosmetic and so on. Explosion hazard: This product is flammable, away from fire sources. Can be dry, alcohol-resistant foam, water spray, carbon dioxide fire extinguisher Storage: This product should be stored in a cool, ventilated, dry place, according to a general chemical storage and transportation of origin: Dow / Korea SK Packing: 215kg / barrel Propylene glycol is an unsaturated polyester, an important raw material epoxy resin, polyurethane resin, the amount in this area accounted for about 45% of the total consumption of propylene glycol, which is used extensively for unsaturated polyester surface coatings and reinforced plastics.
