Hey there! As a supplier of vacant capsules, I often get asked about what materials these capsules are made of. So, I thought I'd write this blog to share all the deets with you.
Gelatin - The Classic Choice
One of the most common materials for vacant capsules is gelatin. Gelatin is a protein that's derived from animal collagen, usually from the skin and bones of cows or pigs. It's been used in the capsule industry for ages because it's super versatile and easy to work with.
Gelatin capsules are known for their smooth texture and good solubility. They dissolve quickly in the stomach, allowing the contents of the capsule to be released and absorbed efficiently. This makes them a popular choice for a wide range of applications, from pharmaceuticals to dietary supplements.
If you're interested in gelatin capsules, check out our 00 Gelatin Capsules. These are high - quality capsules that are perfect for various filling needs.
There are two main types of gelatin: Type A and Type B. Type A gelatin is derived from acid - treated collagen, usually from pigskin. It has a lower isoelectric point and is more soluble in acidic solutions. Type B gelatin, on the other hand, comes from alkali - treated collagen, often from bovine hides. It has a higher isoelectric point and is more stable in alkaline environments.
The process of making gelatin capsules starts with dissolving the gelatin in water to form a gel. Then, other ingredients like plasticizers (such as glycerin) are added to make the capsules more flexible and less brittle. The mixture is then poured into molds to form the capsule shells. After drying, the capsules are ready to be filled.
Our Empty Gelatin Capsule Shell is a great option if you want to fill your own capsules. They come in different sizes and are made with high - grade gelatin for optimal performance.
Vegetarian and Vegan Alternatives
Not everyone can use gelatin capsules, especially vegetarians and vegans. That's where alternative materials come in.
HPMC (Hydroxypropyl Methylcellulose)
HPMC is a popular vegetarian alternative to gelatin. It's a cellulose - based polymer that's derived from plant sources, usually wood pulp or cotton. HPMC capsules are tasteless, odorless, and have excellent clarity. They are also resistant to microbial growth, which is a big plus in the pharmaceutical and supplement industries.
One of the advantages of HPMC capsules is that they have a lower moisture content compared to gelatin capsules. This means that they are less likely to interact with moisture - sensitive ingredients. They also have a wider pH stability range, which makes them suitable for a broader range of formulations.
Pullulan
Pullulan is another vegan option. It's a polysaccharide produced by a fungus called Aureobasidium pullulans. Pullulan capsules are extremely pure and have a high degree of biocompatibility. They are also very stable and can be used with a variety of active ingredients.
Pullulan capsules are known for their excellent oxygen and moisture barrier properties. This helps to protect the contents of the capsule from oxidation and degradation, which is crucial for maintaining the efficacy of the product inside.
Starch - Based Capsules
Starch is also used to make vacant capsules. Starch is a natural polymer that's abundant in plants like corn, potato, and wheat. Starch - based capsules are biodegradable and have good mechanical properties.
The process of making starch capsules involves gelatinizing the starch in water and then adding other additives to improve the properties of the capsule. Starch capsules can be tailored to have different dissolution rates depending on the specific requirements of the product.
Other Materials
There are also some other materials that are used in the production of vacant capsules, although they are less common.
Pectin
Pectin is a polysaccharide found in the cell walls of plants. It can be used to make capsules, especially for applications where a slow - release mechanism is desired. Pectin capsules can form a gel - like matrix in the stomach, which can control the release of the active ingredients over time.
Chitosan
Chitosan is a natural polymer derived from chitin, which is found in the exoskeletons of crustaceans. Chitosan capsules have some unique properties, such as antibacterial and antifungal activity. They are also biocompatible and biodegradable.
