In recent years, plant-based alternatives such as vegetarian capsules have emerged, catering to vegan and vegetarian diets.

In addition to gelatin, the fill material can comprise oils, powders, or pastes containing the active ingredient. Common fill materials include essential fatty acids, vitamins, or herbal extracts. Additionally, excipients like glycerin and sorbitol are often added to improve the flexibility and durability of the softgel capsule, ensuring a high-quality product.

Types of Softgel Encapsulation

Traditional Softgel Encapsulation

Traditional softgel encapsulation utilizes a standardized method where gelatin is heated and combined with the filling material in a controlled environment. This method is widely used for various nutraceutical and pharmaceutical applications. The traditional approach allows for simplicity and consistency in production, ensuring that each softgel contains the specified amount of the active ingredient.

Furthermore, traditional methods have been optimized over the years to enhance efficiency and product quality. Manufacturers can produce softgels in varying sizes and shapes, depending on the desired application and market requirements.

Two-Piece Softgel Encapsulation

Two-piece softgel encapsulation offers an alternative to the traditional approach by allowing the use of a two-part capsule apparatus. This method is particularly beneficial for encapsulating powders and granules that may be difficult to fill into a single softgel capsule.

This technique provides flexibility in formulation and enables manufacturers to combine multiple ingredients within one capsule. It also allows for tailored release profiles for different active ingredients, enhancing the product’s effectiveness and appeal.

Specialty Softgel Encapsulation

Specialty softgel encapsulation refers to the use of advanced techniques to produce softgels that meet specific functional or performance requirements. This may include enteric-coated softgels designed to dissolve in the intestines rather than the stomach, which can be vital for protecting sensitive ingredients from gastric acids.

Another example is the use of proprietary technologies to create softgels with delayed-release properties. Specialty softgels can cater to niche markets, providing unique solutions tailored to meet various consumer needs and preferences.
