Sorbitol (D-Glucitol) 70% Solution / 98.5%+ Crystalline Powder CAS No. 50-70-4 Food, Pharmaceutical & Cosmetic Grade
Sorbitol, available as a 70% aqueous solution or 98.5%+ crystalline powder, is produced via advanced catalytic hydrogenation of glucose derived from corn, wheat, or other starches . It features excellent hygroscopicity, a cool sweet taste (approximately 50-60% as sweet as sucrose with one-third fewer calories) , and exceptional chemical stability. As a hexahydric alcohol (polyol) isomeric with mannitol , it is widely used as a humectant, sweetener, texturizer, and excipient across the food, pharmaceutical, and cosmetic industries . Its high purity and consistent quality make it ideal for critical applications requiring precise functional properties. Each batch is rigorously tested using HPLC analysis to ensure consistent quality meeting international pharmacopoeial and food-grade standards.
Scope of Application
-
Food & Beverage Industry: Used as a low-calorie bulk sweetener and humectant in sugar-free confectionery, chewing gum, baked goods, diabetic foods, jams, and diet beverages to retain moisture, extend shelf life, and provide texture without promoting dental caries .
-
Pharmaceutical Industry: Serves as a versatile excipient, functioning as a sweetener in liquid medications, a plasticizer in gelatin capsules, a diluent in tablet formulations (particularly chewable tablets), a stabilizer in suspensions, and an osmotic laxative for therapeutic use .
-
Cosmetics & Personal Care: Acts as a humectant and skin conditioning agent in toothpaste, mouthwash, creams, lotions, and deodorants, attracting moisture to the skin and maintaining product texture .
-
Chemical Industry: Serves as a key raw material for the synthesis of Vitamin C (ascorbic acid) through fermentation and chemical processes, and for the production of surfactants (Spans and Tweens), polyurethane foams, and plasticizers .
-
Industrial Applications: Used in cigarette manufacturing to maintain moisture in tobacco, in adhesives, and as a humectant in textile processing .
