Product Description of Glycerin CAS#56-81-5
Glycerin is a vital basic organic raw material with extensive applications in industry, medicine, and daily life, currently encompassing around 1,700 uses. It is primarily utilized in medicine, cosmetics, alkyd resins, tobacco, food, acid resins, celluloid, explosives, and textile printing and dyeing. While consumption in areas such as alkyd resins, celluloids, and explosives is declining, its use in medicine, cosmetics, and food continues to expand.
After hydrolysis in the body, glycerin can serve as a nutrient source. Additionally, it finds broad applications across textiles, food, papermaking, metal processing, paints, daily chemicals, petrochemicals, pharmaceuticals, tobacco, the military industry, and other sectors.
