Description
Sorbitol solution is a clear, viscous, aqueous solution consisting mainly of sorbitol, a sugar alcohol (polyol) produced by the catalytic hydrogenation of glucose. The solution typically contains about 70% sorbitol in water and is widely used in the food, pharmaceutical, cosmetic and chemical industries. Sorbitol solution is known for its mild sweetening power (about 60% of that of sucrose), its Hygroscopic properties (moisture retention) and its stability in varying pH values.

Applications
Sorbitol solution is applied in various ways, for instance:
1. Pharmaceutical Industry
Applied as a filler in tablets and capsules. Solvent and carrier in liquid medicines and syrups. Has a laxative effect at high doses.
2. Cosmetics & Personal Care
Used as a wetting agent (humectant) in creams, lotions, toothpaste and mouthwash. Increases viscosity and improves stability of emulsions.
3. Food Industry
Used as a food additive E420. Used as a low-calorie sweetener in “sugar-free” products such as candy, chewing gum, cakes and diet foods. Serves as a moisture retention agent in baked goods and jellies. Improves mouthfeel and stability in beverages.
4. Industrial Applications
Raw material for the production of vitamin C (ascorbic acid). Used in the production of polyols, resins and plasticizers. Added to antifreeze as a biodegradable component.
