Why Choose Vegetarian Capsules?

Vegetarian capsules are very stable in storage because of their lower moisture content compared to other types of capsules. A lower hygroscopicity and higher stability in different ranges of temperatures make them easier to store. In terms of solubility, these capsules dissolve well at a human body temperature of (37°C/ 98°F).


What Are Hydroxypropyl Methylcellulose (HPMC) Empty Hard Capsules?

The raw materials used for HPMC capsules are natural plant fiber made from a specific chemical modification. The material is called hydroxypropyl methylcellulose or HPMC. HPMC capsules are used in the pharmaceuticals of the United States, Europe, the United Kingdom, Japan, and China. The quality of this capsule is stable and universal. 

Hydroxypropyl methylcellulose is derived from non-transgenic (non-GMO) plants, so the capsules are plant-derived capsules. They are safer because they have no chlorinated ethanol residues and are resistant to bacterial contamination.   

Water Content

The water content for HPMC capsules is between 5 percent and 7 percent. The minimum requirement for HPMC capsules is 3 percent. This is suitable for filling with many different types of contents and ensures no cross-linking reactions because the molecular structure is stable. They are more suitable for fillings that are oxygen-sensitive and for quick-release drugs, therefore making the contents safer with more thorough dissolution, thus being more effective.

Moisture Levels

Because hydroxypropylene methylcellulose (HPMC) hollow capsules have a low moisture content and a stable molecular structure, they are suitable for Chinese native medicine preparations. The product’s storage and shipment requirements are also less strict. Because they are made of plant fiber, they are processed by the human body without any harmful side effects. HPMC capsules also meet various dietary restrictions, including Kosher and Halal.

Ideal Storage Conditions For Empty Capsules

We recommend storage of any of our capsules at 10 to 30 degrees Celsius and between 25 to 65 percent humidity. Cartons should be stored right side up in a well-protected area away from heat sources like space heaters, sunlight, steam pipes, or incandescent electric lamps. They should be stored away from the exterior walls of buildings also.
