Application
1. It is used in cosmetics and personal care. Glycerin is highly valued in the cosmetics and personal care industry due to its moisturizing and humectant properties. It’s a key ingredient in a vast array of products including lotions, creams, soaps, and shampoos.
2. In pharmaceuticals and medical applications. Glycerin is one of the most widely used ingredients in medical prescriptions, second only to water. It has a wide of range of applications in this industry, and is often used to help make prescriptions more palatable. In the pharmaceutical industry, glycerin is used as a solvent, sweetener, and humectant in various formulations such as cough syrups and oral care products. It’s also utilized in topical ointments and creams for its soothing and moisturizing properties, beneficial in treating dry skin and other skin conditions. Glycerin plays a role in the formulation of gel capsules and suppositories, aiding in medication delivery.
3. As a food additive, glycerin serves multiple functions: it acts as a sweetener, a humectant (helping to retain moisture), and a preservative. It’s commonly used in baked goods, candies, and meat products to maintain freshness and enhance texture. Glycerin’s non-toxic nature makes it a safe and versatile ingredient in food production.
4. In industrial applications:
Explosives Production: The manufacturing of nitroglycerin, a key component in various explosives, is one of the primary industrial uses of glycerin. Nitroglycerin is produced by the nitration of glycerin, typically involving a reaction with nitric acid. Glycerin enhances the burning rate of explosive mixtures and acts as an oxidizer in the production of nitric acid from ammonia.
Paint and Varnish Industry: In the production of paints and varnishes, glycerin is used as a plasticizer to improve texture and consistency. It helps paints and varnishes achieve the right viscosity and flow, enhancing application and finish quality.
Textile Industry: In textile manufacturing, glycerin may be used in dyeing fabric because of its viscosity, hygroscopic properties, and its ability to penetrate fabric and suspend dyes. Surprisingly, glycerin also finds a role in reducing static cling in textiles.
Agrochemicals: Glycerin is utilized in the agrochemical industry, especially in the formulation of pesticides and herbicides. It serves as a solvent and stabilizer, aiding in the effective delivery and longevity of these products.
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.
