As a wide range of chemical products, can be used for acetate fiber, nitrate fiber and other plasticizers and solvents, natural rubber and synthetic rubber also have plasticizing effect, and does not affect the vulcanization operation. As an important chemical raw material, triacetin has been widely used in food, medicine, cosmetics, industry and other fields.
1. Food industry
Increase the viscosity and taste of food: triacetin is a colorless transparent liquid, which can increase the viscosity of food when added to food, and make food taste smoother.
Increase the stability of food: triacetin is a stable compound, which can improve the stability of food and extend the shelf life of food after being added to food.
Enhance the stability of spices: triacetin can be used as a stabilizer of spices, which can extend the freshness life of spices and stabilize the flavor.
As a thickener: triacetin can be used as a thickener to increase the consistency and viscosity of food, making it easier to process and package.
As an emulsifier: triacetin has good emulsifying performance, which can make the slurry and oil fully mixed and play an emulsifying effect.
2. Pharmaceutical industry
As a drug sustained release agent: triacetin can be used as a drug sustained release agent, by regulating the release rate of drugs, extend the duration of drug action, improve the efficacy of drugs.
As a solvent: triacetin can be used as a solvent to help the drug dissolve and facilitate oral or injectable administration.
As a component of capsules: triacetin has good capsule preparation properties and can be used as a component of capsules, which is helpful for encapsulation and storage of drugs.
3. Cosmetics industry
Thickener: triacetin can increase the viscosity of cosmetics, making them easier to use and apply.
Humectant: triacetin has good moisturizing properties, can absorb moisture and lock water, keep the skin moist and soft.
Lubricants: triacetin provide lubrication, making cosmetics easier to apply and push on the skin, enhancing the application experience.
Enhanced stability: triacetin can increase the stability of cosmetics and prevent their delamination or deterioration.
4. Industrial
Plasticizer: triacetin is widely used in the plastics industry, which can enhance the flexibility, ductility and toughness of plastics, and improve the processing performance of plastics.
Lubricant:triacetin can reduce the friction coefficient of the material, reduce friction failure, and improve the lubrication performance of the material.
Additives: triacetin can be used as chemical reaction additives, participate in the reaction, and promote the reaction.
Solvent: because of its good solubility and lubricity, triacetin can be used as a solvent for coatings, paints and cleaners.
Gasoline additive: triacetin can reduce the amount of lead in the air. In printing and dyeing industry, triacetin can be used as a bulking agent and stabilizer of cellulose acetate. Triacetin is used as a plasticizer in ink, cellulose, film and some alkaline solvents, and is also used as a plasticizer for synthetic plastic films. Triacetin can also be used as a fixed liquid for meteorological chromatography to separate and analyze gases and aldehydes.
Storge & Handling
Shall be stored in a cool, dry place to maintain its stability and prolong its shelf life. Proper storage conditions are crucial to prevent product degradation, as ethylene carbonate can slowly decompose in the presence of moisture.
