What is a HPMC capsule?
What is a HPMC capsule?
HPMC stands for hydroxypropyl methylcellulose or hypromellose for short. HMPC is the material from which most supplement capsules are made. It is a clear, tasteless, vegetarian and vegan appropriate material. It is normally made by extraction from wood pulp.
How do you make HPMC capsules?
The method used for manufacturing HPMC capsules conventionally has been adapted from the gelatin capsule making process. The process involves dipping cold pin moulds into a hot solution of HPMC followed by gelation at low temperature and then drying to obtain the capsules.
What is the composition of capsule shell?
Capsules are made up of gelatin (hard or soft) and nongelatin shells generally derived from hydrolysis of collagen (acid, alkaline, enzymatic, or thermal hydrolysis) from animal origin or cellulose based.
Are HPMC capsules hard or soft?
Our capsule technologies include hard gelatin capsules, HPMC capsules, soft gelatin capsules, liquid-filled hard capsules, and dry-powder inhalation capsules.
What is hypromellose capsule made of?
The Vcaps® capsules used are manufactured by Capsugel, and produced using the raw material, hypromellose. Hypromellose is a cellulose material derived from softwood trees, mainly pine and spruce trees that are grown and harvested from plantations in the southeastern United States.
What are cellulose capsules made of?
Cellulose capsules, also called vegetarian or vegan capsules, are made from the fibers of plants. Like gelatin, the resulting capsules are tasteless, odorless, and colorless. Pros: They are vegetarian and kosher-friendly.
What is the major component of capsule?
Manufacturing materials Gelatin capsules, informally called gel caps or gelcaps, are composed of gelatin manufactured from the collagen of animal skin or bone. Vegetable capsules, introduced in 1989, are made up of cellulose, an important structural component in plants.
Why gelatin is used in capsules?
Gelatin is widely used to create the shell for both hard and soft capsules, providing an effective means of protecting the contents from light, atmospheric oxygen, contamination and microbial growth as well as masking taste and odor. Hard capsules represent 75% of the gelatin capsule market.
Are HPMC capsules enteric?
Enteric coated HPMC capsules can thus be considered to provide a good container for drugs during the early development phase providing the possibility of drug release either in the small intestine or towards the colon.
Are HPMC capsules safe?
Hydroxypropyl methylcellulose (HPMC), also known as hypromellose, is produced from cellulose, a natural polymer and fiber, which is considered to be safe for human consumption.
How can you tell the quality of a capsule?
Finished capsules are evaluated by the following tests:
- a. Permeability and sealing.
- b. Potency and impurity content.
- c. Weight variation test.
- f. Uniformity of content.
- g. Disintegration time test for capsules.
- h. Dissolution test for capsules.
- i. Moisture content.
- j. Moisture permeation test.
