Soft Gelatin Capsules: Everything You Need to Know about Manufacturing
Soft gelatin capsules are a popular and convenient dosage form that is widely used in the pharmaceutical, nutraceutical, and cosmetic industries. They are typically made from gelatin, water, plasticizers, and other ingredients that provide the desired properties such as stability, bioavailability, and taste masking. In this article, we will take a closer look at the soft gelatin capsule manufacturing process, its benefits, and some frequently asked questions.
What is a Soft Gelatin Capsule?
A soft gelatin capsule, also known as a softgel, is a one-piece, hermetically sealed capsule that contains a liquid, semi-solid, or gel formulation. Softgels are usually made from gelatin, a protein derived from animal collagen, which is dissolved in water and mixed with plasticizers and other ingredients to form a gelatin solution. The gelatin solution is then encapsulated around the active ingredient and sealed to create the final softgel.
Benefits of Soft Gelatin Capsules
There are several advantages of using soft gelatin capsules as a dosage form:
Improved Bioavailability: Softgels can improve the bioavailability of certain drugs and nutrients due to their ability to dissolve quickly and easily in the stomach and release the active ingredient for absorption.
Taste Masking: Softgels can mask the unpleasant taste and odor of certain drugs and nutrients, making them easier to swallow and more palatable.
Customization: Softgels can be customized to suit the specific needs of the product, such as size, shape, color, and printing.
Stability: Softgels can provide improved stability for certain drugs and nutrients, protecting them from degradation caused by light, oxygen, and moisture.
Soft Gelatin Capsule Manufacturing Process
The manufacturing process for soft gelatin capsules involves several steps:
Gelatin Preparation: The gelatin is dissolved in water and mixed with plasticizers and other ingredients to form a gelatin solution.
Fill Material Preparation: The active ingredient and other fill materials are prepared and mixed together.
Encapsulation: The gelatin solution is injected into a two-piece mold, and the fill material is added to one half of the mold.
Sealing: The two halves of the mold are sealed together to form a hermetically sealed capsule.
Drying: The softgels are dried to remove excess moisture and ensure that they are stable and free from microbial growth.
