Applications of PG
1. The raw materials for resin, plasticizers, surfactants, emulsifiers, and emulsifiers can also be used as antifreeze and heat carriers
2. For gas phase chromatography fixed solution, solvent, antifreeze, plasticizer and dehydration agent
3.Loan solvent; humidizer; moisturizer; antidote; antioxidant; tissue improvement agent; surfactant; stabilizer; thickener; dough regulator; emulsifier; seasoning agent; processing agent. GB2760 ~ 96 is listed as food processing additives. It is mainly used for extraction solvents of various spices, pigments, preservatives, and checalbook vanilla beans, roasted coffee kernels, and natural spices. Moisturizing and soft agents of candy, bread, packaging meat, cheese, etc. It can also be used as a mold -proof auxiliary agent for noodles and stuffing. Adding 0.006%to soymilk can make the flavor unchanged during heating. It is made into white and shiny packaging tofu, and frying will increase volume.
4. Pig -glycol is the intermediate of the germine benzazole.
5. As a solvent, preservatives, pigments, antioxidants and other food additives that are difficult to dissolve in water such as water are dissolved in water, and then added to the food; it has strong hygroscopicity and has a moisturizing and frosting effect on food. my country's regulations can be used for pastry, with a maximum usage of 3.0g/kg.
6. Pateyl glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. The dosage of this area accounts for about 45%of the total consumption of propylene glycol. This unsaturated polyester is large for surface coatings and enhanced plastic. The viscosity and hygroscopicity of propylene glycol are well -toxic. Therefore, it is widely used in the food, medicine and cosmetics industries as wetting agents, antifreeze, lubricants and solvents. In the food industry, propylene glycol and fatty acids react to generate propylene glycol fatty acid. Chemicalbook is mainly used as a food emulsifier; propylene glycol is an excellent solvent for condiments and pigments. Pigbolly is often used as a solvent, softener, and gumin agent for making various types of ointment, ointment, and glycrastasus in the pharmaceutical industry. Because propylene glycol has good solubility with various types of spices, it is also used as a solvent and softener for cosmetics. Pigbolly is also used as a solvent for tobacco dampness agents, moldproofing agents, food processing equipment lubricating oil and food marking ink. The hydraulic solution of propylene glycol is an effective antifreeze.
7. As a pharmaceutical carrier, particle pharmaceutical agent. It can be used as a moisturizer in cosmetics, softeners, solvents, etc. The tobacco industry can be used as smoke, tobacco moisturizers, preservatives, etc. The food industry is used as fragrance, edible pigment solvents, Chemicalbook food packaging soft agents, food anti -adhesives, etc. It can also be used to produce unsaturated polyester resins, as well as plasticizers, dehydrated agents, surfactants, curing agents, binders, etc. It can also be used in industries such as paint, pesticides, coatings and other industries
8. Aviation removal, frozen agent and freezer, food and spices, fragrance agents, cosmetics and personal health products, heat transfer, hydraulic and brake fluid, paint and coatings, pet food/animal feed, drugs, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, polyurethane, Unsaturated polyester resin.
9. Solvent, organic synthesis, antifreeze, plasticizer, sterilizer. Gas chromatography analysis standards. Gas chromatography fixed liquid (maximum temperature of 150 ° C, solvent is chloroform), isolated analysis alcohol, ester and ketone, etc.

Copylene glycol is well -dissolved, with less toxicity and irritation. It is widely used as injections (such as intramuscular injection, venous injection) and non -injection drug preparations (such as oral solution, eye preparations, ears, dental preparations, rectal vaginal vagina, rectal vaginal vagina Soluks, extracts and preservatives of preparations, transparent preparations, etc.) are better solvents than glycerin, which can dissolve many substances such as corticosterol (sex hormone), chloramphenicol, sulfa drugs, Barbich acid Salt, Liserin, quininine, acetic acid dehumidone, sulfuric acid extension hubin, nitrogen hydrochloride, vitamin A, vitamin D, many volatile oils, most alkaloids and many weal medicines. As a bacteriostatic agent similar to ethanol, the effect of inhibiting mold is similar to glycerol, which is slightly lower than ethanol. CHICALBOOK plasticizers are usually used as a checked thin film coating material. The equivalent mixing solution with water can delay the hydrolysis of certain drugs and increase the stability of the product products. 15%to 30%propylene solution agent and semi -solid daisy can be used as antibacterial preservatives. About 15%of the proprial dibol partial preparations can be used as a moisturizing agent, 10%to 30%of the propylene glycol gas fog solvent, 10%～ 25 %Propylene glycol oral solution, 10%to 60%injection preparations, 5%to 80%of local dosage should be used as solvents and common solvents.
Packing of PG
200kg/drum
Storage should be at cool, dry and ventilate.
[Stability and storage conditions]： Extremely stable at room temperature, but at high temperature (above 280 ° C), open placing is oxidized; after mixing with 95%ethanol or water, it has chemical stability; it can be sterilized or filtered out and extinguished. bacteria. Copylene glycol is moisture -absorbing, and it should be stood in a cool and dry place to avoid light and closed containers.
