Raw Material Propylene Glycol Pharmaceutical

Introduction

Used as raw material to produce biodegradable memory fiber PTT.

2. Used as raw materials for the production of pharmaceutical intermediates.

3, used as antifreeze agent, organic solvent.

Application

1.It can be used as a solvent for various flavors, colors and preservatives, as an extraction solvent for vanilla beans, roasted coffee granules and natural spices. Moisturizing and softener for sweets, breads, packaged meats, cheese, etc. It can also be used as an anti - mildew agent for noodles and stuffing. Adding 0.006% in soy milk can keep the flavor unchanged during heating and make white and shiny packaged tofu, which will expand in volume when fried in oil.

2.as a solvent, can be preservatives, pigment, antioxidant and other food additives insoluble in water dissolved in it, and then added to food; It has strong hygroscopicity, and has the function of moisturizing and freezing resistance to food. China's regulations can be used for cakes, the maximum usage of 3.0g/kg.
3. Propanediol is an important raw material of unsaturated polyester, epoxy resin and polyurethane resin, which accounts for about 45% of the total consumption of propylene glycol. This unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol has good viscosity and hygroscopicity, and is non-toxic, so it is widely used as hygroscopicity, antifreeze, lubricant and solvent in food, medicine and cosmetics industry. In the food industry, propylene glycol and fatty acid reaction to produce propylene glycol fatty acid ester, mainly used as food emulsifier; Propanediol is an excellent solvent for flavoring and pigment. Propylene glycol in the pharmaceutical industry is often used in the manufacture of all kinds of ointment, ointment of the solvent, softener and excipient, due to the propylene glycol and all kinds of spices have good mutual solubility, so it is also used as cosmetics of the solvent and softener and so on. Propanediol is also used as tobacco humidifier, mildew inhibitor, lubricating oil for food processing equipment and solvent for food labeling inks. The aqueous solution of propylene glycol is an effective antifreeze.

4. As drug carrier and granule drug agent. It can be used as moisturizer, softener and solvent in cosmetics. Tobacco industry can be used as tobacco flavor, tobacco moisturizer, preservative, etc. In the food industry as flavor, food coloring solvent, food packaging softener, food anti-stick agent. Can also be used in the production of unsaturated polyester resin, plastic plasticizer, dehydrating agent, surfactant, curing agent, binder raw materials, etc. Can also be used in paint, pesticide, paint and other industries.
