What Is Liquid Filled Capsules?

 

A liquid filled capsule is a capsule that contains a liquid medication inside, rather than a powder or solid, essentially a capsule shell filled with a liquid solution instead of dry ingredients; the most common type of liquid filled capsule is a softgel capsule, which is made from gelatin and has a flexible shell to hold the liquid filling.

 

Advantages of Liquid Filled Capsules
 

Proper Distribution of Ingredients
If you're using liquid capsules, you will typically get better content uniformity than if you're using powder-filled capsules and tablets. This is because the liquid fills the entire space of the capsule, whereas the powder fills only a small portion of it. In addition, powder capsules absorb moisture from the air while they're being stored, which can cause them to expand and become less consistent.

 

Preferred Choice Of Consumers
For those who need to take a lot of medicine, liquid-filled capsules are the way to go. They're easier to swallow than tablets, they work faster and better, and they're visually attractive. Plus, liquid-filled capsules allow for multiple combinations of release profiles within a single hard capsule.

 

Protect Content Inside The Shell
Liquid-filled capsules have more thermal stability but less oxygen protection. This means that they can be stored at higher temperatures without being affected by heat, but if heat is applied to the inside of your capsule, it will begin to degrade and may release harmful chemicals into your food or drink.

 

Liquid-filled capsules are easier to handle and safer to use
Liquid-filled capsules are designed to be safer and more efficient to handle compared to powder-filled capsules and tablets. The risk of spilling the contents in a powder-filled capsule is higher because there is no barrier between the contents and the outside of the capsule. This can result in exposure to any contaminants present in the powder.

 

Reformulation Is Not Required
Liquid-filled capsules are the new kid on the block. They're easier to produce and maintain and don't require any reformulation. Reformulation is the process of creating a new product that is identical to one that has already been approved. To reformulate a product, you need to change the formula—the ratio of ingredients, the way they are processed, etc. This can be time-consuming and expensive.

 

Good for Taste Buds
When choosing between liquid-filled capsules and powder-filled capsules, there are several reasons why one might choose the other. Many people are looking for a more convenient way to take their medication. Liquid-filled capsules are a great choice for people who have trouble with the taste or odours of tablets. Many people find that tablets cause their mouths to be coated with a film or waxy taste, and they may also experience unpleasant odours.

 

Applications of Liquid Filled Capsules
 

Pharmaceutical Uses: Liquid filled capsules are excellent for oral medications, particularly for drugs that are difficult to produce in solid form. They can hold liquid medicines, suspensions, and oils.


Nutritional Supplements: They are popular for supplements like fish oil, vitamin E, and Omega-3 fatty acids, making it easy for users to take essential nutrients.


Cosmetics: In the cosmetics industry, liquid capsules are used for facial serums, skincare oils, and hair care treatments, allowing for even application.


Food and Beverages: They help deliver precise amounts of food additives, oils, and flavorings while keeping products fresh.

Types Of Seals For Liquid Filled Capsules

 

Sealing tapes or bands
The process is quite simple and is detailed below:

  • The capsule is rectified and its closure is brought into contact with a wheel that collects a small portion of gelatine or liquid HPMC.
  • The wheel rotates around the joint of the capsule applying the hot gelatine or HPMC.
  • The capsule with the band is held in an individual holder until the gelatine or HPMC cools, forming a ring over its seal.

 

Micro spray sealing
This process consists of depositing a micro spray on the top edge of the capsule body and the inside of the capsule lid to generate a seal. The complete step-by-step is as follows:

  • A hydroalcoholic solution is sprayed on the area where the capsule’s body and lid are touching (when closed).
  • Localized heat is applied to the capsule, which lowers its melting point and promotes the bonding of its parts.
  • The capsule is left to dry at room temperature.

 

Sealing fluid
This is the method of applying moisture to the sealing area between the body and the capsule cap, which lowers the melting point of the gelatine.
It is common to immerse the capsules in a liquid bath and then leave them to dry in a fluid bed chamber. It is currently a procedure in disuse because it generates too much stress on the capsule, leading to further deformation.

Preparation of empty capsules and liquid fills
The operator loads empty capsules and liquid fills into their hoppers. Aside from liquids, the equipment can also fill many other materials, such as semi-solids, suspensions, pastes, and waxy substances.

 

Capsule feeding and separation
During this stage, the empty capsules are rectified and transferred to the segments in the vertical position. When each capsule is fed into the segment pore, they are ready for the next step - separation.

 

Liquid dosing and filling
After separation, the lower segment holding empty capsule bodies moves to the filling station. Liquid fills are pumped into the filling station by a peristaltic pump. The pump enables precise liquid dosing without leaking, dripping or air bubbles.

 

Capsule closing
Now the lower segment carrying filled capsule bodies rotates to the closing station. As with conventional capsule filling machines, the upper segment is lined up with the lower one. A row of pins pushes the bodies up from the bottom of the lower segment to close the capsules.

 

Filled capsule transfer
In the above four steps, any capsule that fails to separate or close is rejected by vacuum. In this stage, the closed capsules are pushed out of the segments into the holes of a rotary disc. All segments are then cleaned by vacuum and go back to the first place for the next circle.

 

Filled capsule sealing
The sealing mechanism is mounted under the slat conveyor. It comprises two sealing rollers, two gelatin bowls, a water tank, and a gelatin tank. By the way, two gelatin bowls and the gelatin tank are equipped with heaters to maintain the temperature of the gelatin.

 

Sealed capsule drying
The sealed capsules are then moved to the drying carriers from the slat conveyor and transferred into the drying box. The drying box uses filtered indoor air at a constant room temperature to dry the capsules on the carriers.

FAQ

 

Q: How do liquid-filled capsules work?

A: A hard gelatin capsule filled with liquid medication is made with two halves — the rim of one half is smaller in diameter than the other, so the other half's larger rim fits over it and seals the capsule. The two capsule halves are manufactured separately, then later filled using different machinery.

Q: How do you swallow big liquid capsules?

A: Put the capsule on your tongue and take a medium sip of water – do not swallow yet.
Bend the head forward by tilting your chin slightly toward your chest.
Swallow the capsule and the water with the head bent forward.

Q: Do liquid capsules work better?

A: In general, your body will benefit more from an appropriate dose of either type of liquid-filled capsule than it will from tablets. That's because liquid ingredients are more easily and quickly absorbed into the body. In other words, liquid gels work faster than tablets.

Q: Which is better, softgels or capsules?

A: Softgels are an efficient delivery system for oils and liquids. Softgels have a longer shelf life than tablets or capsules. Softgels are very easy to swallow, even more so than hard shell capsules. Softgels can deliver nutrients in the most desirable manner, either immediate-release or sustained-release.

Q: What are liquid capsules made of?

A: These capsules are made with gelatin or other gelling agents like hydroxypropyl methyl-cellulose (HPMC). Gelatin capsules are flavorless, odorless, and affordable. Capsules that are filled with liquid can also be hard capsules made from gelatin or HPMC, but there's another option, too: softgel capsules.
