Empty HPMC Capsules

  • Pharmaceutical Quality
  • High Closure Reliability
  • Worldwide Stock Locations

HPMC capsules are vegan and vegetarian friendly hard caps made from natural wood pulp.

HPMC capsules are manufactured from cellulose polymer and are the most popular alternative to gelatin capsules because they are suitable for vegans and vegetarians. They are often referred to as “veggie capsules” or “vegetarian capsules”.

HPMC which is an abbreviation of Hydroxypropyl Methyl Cellulose which is globally referred to also as “Hypromellose” is an ideal material to use for capsules as it is less sensitive towards moisture when compared to gelatin.

HPMC is derived from plant cellulose and was one of the first non-animal alternatives available on the market. HPMC capsules also help to protect the ingredients from degradation by insulating against temperature fluctuations or moisture exposure, the stability of the capsule material you use is critical in product development and scaling your manufacturing

Our HPMC capsules are designed to run smoothly on encapsulation machinery including the FACF and SACF to avoid downtimes in production.

HPMC has been a widely used solution for vegetarian capsules in pharmaceutical applications since 1998. It rose to popularity in the early 2000s as it was discovered to be a stable polymer with a low moisture content that makes it suitable for moisture-sensitive ingredients. It is also extremely resistant to higher than average heat and humidity.

Hypromellose based capsules meet a lot of people's requirements as consumers move from traditional gelatin capsules towards non-animal-derived alternatives. The ability to withstand temperature excursions as well as meeting religious and dietary requirements make HPMC the preferred choice for new pharmaceutical and nutraceutical product development.

Bioavailability & Acidity Resistance 

Hypromellose capsules can also have a positive effect on poor bioavailability. It has been proven that HPMC can interact with poorly soluble APIs leading to lower crystallisation rate in the GI tract.In some cases, HPMC capsules can affect in vivo performance by helping to maintain supersaturation.

HPMC capsules are manufactured using a gelling agent that promote enteric properties, meaning that sensitive ingredients are protected from acidity in the stomach and complete dissolution in the intestine. They also mask from bad taste and prevent gastric reflux for products such as fish oils, and have become the solution of choice for numerous probiotics, herbal or mineral formulations.
