Product Description

Propylene glycol, scientific name "1, 2-propylene glycol". There's a chiral carbon atom in the molecule. The racemate is a viscous liquid with easy hygroscopicity and a slightly spicy taste. Soluble in water, acetone, ethyl acetate and chloroform, soluble in ether. It can be dissolved in many essential oils, but it is not miscible with petroleum ether, paraffin and grease. More stable to heat and light, more stable at low temperatures. Propylene glycol can be oxidized to propionaldehyde, lactic acid, pyruvate and acetic acid at high temperatures.

use
1. Cosmetics and personal care
Moisturizer: Propylene glycol can absorb and lock in water, increase the water content of the skin, and keep the skin moist and soft. It is often added to skin care products such as lotions, creams, toners, serums, etc., to help improve the dry skin and make the skin more delicate and smooth.
Solvent: As a polar aprotic solvent, propylene glycol can effectively dissolve many organic compounds, especially substances containing hydrophilic groups such as hydroxyl and carboxylic groups, so it is often used to dissolve various ingredients in cosmetics, such as flavors, colors, preservatives, etc., to ensure the uniform distribution of product ingredients.
Penetration enhancers: help the active ingredients in cosmetics to better penetrate into the skin, thereby enhancing the efficacy of the product, such as whitening ingredients, anti-wrinkle ingredients, etc., to more deeply act on the bottom of the skin, play a better beauty effect.
Prevent solidification: It can reduce the freezing point of the product, prevent the cosmetics from solidifying or hardening at low temperatures, and maintain its good performance and appearance.
2. The field of medicine
Drug solvent and carrier: propylene glycol can be used as a solvent or carrier of some drugs, which can dissolve insoluble drugs, improve the stability and bioavailability of drugs, and is conducive to the absorption and effect of drugs. It is commonly found in some oral solutions, injections, external ointments and other drug preparations.
Ointment matrix: used in the pharmaceutical industry as a solvent, softener and excipient for the manufacture of various ointments and ointments, so that the ointment has a suitable consistency and ductility, easy to apply and absorb, and can also help drugs better release and penetrate into the skin lesions, promote local blood circulation and wound healing.
Moisturizing and lubricating: Its moisturizing properties can be used in some medical supplies, such as medical lubricants, moisturizing dressings, etc., to keep the skin or mucosa moist, reduce friction and discomfort.
Antifreeze: The aqueous solution of propylene glycol has a low freezing point, which can be used as an antifreeze for drugs to prevent drugs from freezing and deteriorating in a low temperature environment and ensure the quality stability of drugs during storage and transportation.
3. Food industry
Humectants and stabilizers: can form hydrogen bonds with water, has good hygroscopic property, can be used to maintain the moisture of food, prevent food drying, hardening or deterioration, extend the shelf life of food, often used in baked goods, candy, chocolate, meat products, etc., so that the product to maintain a soft, moist taste and good appearance.
Solvent: as a solvent can be used to dissolve food additives, spices, pigments, etc., so that these ingredients can be evenly dispersed in the food, to ensure the flavor and color of the food is consistent, such as in beverages, jelly, chewing gum and other foods have applications.
Antifreeze agent: The aqueous solution of propylene glycol has a low freezing point and can be used as an antifreeze agent for food, which is used in frozen food to reduce the freezing point of food and prevent the formation of large ice crystals during the freezing process, thus maintaining the texture and taste of food.
Emulsifier: Propylene glycol fatty acid ester generated by the reaction of propylene glycol and fatty acid is an excellent food emulsifier, which can be used to improve the emulsification performance of food, so that the oil phase and the water phase can be better mixed, improve the stability and taste of food, often used in dairy products, salad dressing, ice cream and other foods.
4. Industrial sector
Unsaturated polyester resin raw materials: propylene glycol is one of the important raw materials for the manufacture of unsaturated polyester resin, and other monomers can produce polyester resin with good performance, this resin is widely used in surface coatings, reinforced plastics, FRP products and other fields, with excellent mechanical properties, corrosion resistance and insulation properties.
Coating and ink solvent and film forming agent: as a solvent can dissolve the resin and pigment in the coating and ink, so that it has good fluidity and coating performance, while propylene glycol can also participate in the film forming process, improve the gloss, hardness and wear resistance of the coating, improve the quality and performance of the coating and ink.
Plasticizer: can be used as a plasticizer in the plastics industry, can increase the flexibility, ductility and cold resistance of plastics, reduce the hardness and brittleness of plastics, make plastic products more soft and durable, often used in the processing and production of polyvinyl chloride (PVC) and other plastics.
Antifreeze and heat transfer fluid: due to its lower freezing point and higher boiling point, propylene glycol aqueous solution can be used as antifreeze and heat transfer fluid, widely used in automotive engine coolant, solar water heater heat transfer medium, industrial cooling circulation system, etc., can effectively prevent equipment from freezing and damage in low temperature environment, and transfer heat to ensure the normal operation of equipment.
5. Tobacco industry: used as a humidifier and anti-mold agent for tobacco, which can maintain the humidity of tobacco, prevent tobacco from drying and crushing, inhibit the growth of mold, and improve the quality and storage life of tobacco.
