| Catalog Number | CI-HC-0134 |
| Product Name | Sorbitol (CAS 50-70-4) |
| CAS | 50-70-4 |
| Structure |  |
| Description | Sorbitol is a sugar alcohol that is commonly used in various personal care products like toothpaste, mouthwash, and skincare products; it functions as a humectant, which helps to retain moisture in the skin. Sorbitol is a natural sugar alcohol found in many fruits and vegetables, but it can also be synthesized chemically. |
| Appearance | colorless, odorless, crystalline powder with a sweet taste |
| Application | 1. Food industry: Sorbitol is commonly used as a sugar substitute, flavor enhancer, and humectant in various food products, including baked goods, candy, and frozen desserts. 2. Pharmaceuticals: It is used as an excipient or an inactive ingredient in medicinal formulations, where it helps to maintain the stability and shelf-life of the products. 3. Personal care products: Sorbitol is added to personal care products like toothpaste, mouthwash, and skin moisturizers as a humectant to retain moisture and prevent drying. 4. Chemical industry: It is used as a raw material in the production of various chemicals, including sorbitan esters, propylene glycol, and isosorbide. 5. Agriculture: Sorbitol is used as a foliar spray in the cultivation of fruits, vegetables, and ornamental plants to enhance their growth and yield. 6. Animal feed: It is used as a feed ingredient or a source of energy for livestock and poultry. 7. Industrial applications: Sorbitol is used in the manufacture of resins, adhesives, plastics, and elastomers, where it acts as a plasticizer or a binder. |

Four different formulations of carrageenan-based hydrogels were prepared with different concentrations of sorbitol and glycerol, which can be used for cosmetic and medical purposes. The optimal formulation was the one containing 20% sorbitol and 1.5% glycerol, which produced hydrogels with the highest Young's modulus and the lowest water absorption.
Preparation of carrageenan-based hydrogel
Hydrogels based on a 2% carrageenan solution were chosen to create cosmetic pads. Four different formulations were developed, varying in the amounts of sorbitol and glycerin. The preparation involved mixing carrageenan with a 60% (w/v) sorbitol solution, resulting in final sorbitol concentrations of 5% and 20%. Glycerin was then added at final concentrations of 1.5% and 6% (w/w) in the carrageenan/sorbitol blends, while the amount of carrageenan remained constant at 2% (w/w). Each mixture also included equal amounts of active ingredients such as hyaluronic acid, panthenol, allantoin, soybean oil, grape seed oil, tocopherol, and goji berry extract. Phenoxyethanol was used as a preservative, and polysorbate 80 served as a solubilizer. The mixtures were poured into molds (flat or cylindrical) and cooled at 2°C for 30 minutes. Finally, the hydrogels were soaked in a 1 M potassium chloride solution at 2°C for 24 hours.
