Starch Cellulose Hollow Capsules
Other ingredients can include polyethylene glycol, glycerol, fructose, and corn syrup. These components are used to improve the flexibility of the pullulan film.Pullulan compositions are used in pharmaceutical, veterinary, food, and cosmetic products. They have good setting properties in aqueous solutions and can be used in containers for predosed formulations. They also improve the mechanical properties of films. They can be combined with other hydrosoluble polymers to enhance their properties. Preferred examples include pectin, alginates, and high molecular-weight polyethylene glycol.In addition to the carrageenan, pullulan capsules can include flavoring agents.
These agents are typically provided in a small quantity but sufficient to impart a pleasing flavor to the capsule. Additionally, pullulan capsules can be coated with an enteric coating agent that improves the capsules' enteric properties.There are several advantages of pullulan capsules over gelatin or other HPMC-based capsules. In addition to providing an excellent oxygen barrier, pullulan capsules also disintegrate rapidly and isolate odor. These advantages make pullulan a superior choice for oxygen-sensitive materials. Additionally, pullulan capsules come in a variety of shell types.Pullulan capsules are two-piece units made from a polysaccharide that compares favorably to gelatin.
The two-piece capsules have an average transit time of five seconds and are generally disintegrated quickly in the stomach. Complete disintegration occurs on average approximately 34 minutes after administration.Gelatin and HPMC capsules are compatible with some kinds of liquids. HPMC is better suited for products that are hygroscopic. HPMC capsules are compatible with more oxidizing agents than gelatin.The market for pullulan is expected to grow substantially in the future, thanks to its increasing usage in cosmetic products. The product is also finding applications in biotechnology, agriculture, and environmental protection. A new report from Dataintelo examines the pullulan market. The report segments the market by application and type.
