HPMC Capsules (Hydroxypropyl methylcellulose) or “veggie caps” are a viscoelastic polymer derived from cellulose. When used in capsule form, it offers an excellent alternative to traditional gelatin capsules. Not only is HPMC sourced from plant cellulose, making it vegan and vegetarian safe, it also boasts several advantageous characteristics.
Key Features of HPMC Capsules
- Increased Stability: HPMC has a lower moisture content compared to gelatin, contributing to better stability and reduced risk of cross-linking.
- Suitable for Sensitive Ingredients: The inert nature of HPMC makes it an ideal choice for encapsulating sensitive ingredients that may react with other capsule materials.
Advantages Over Gelatin Capsules
While gelatin capsules have been a standard in the pharmaceutical industry, HPMC capsules address certain limitations:
- No Animal Sourcing: Gelatin capsules are derived from animal collagen, posing issues for those with dietary restrictions or ethical considerations.
- Vegetarian Appeal: As plant-based options gain popularity, veggie caps provide an appealing alternative for a broader consumer base.
Popularity
Montana Global Health always recommends veggie caps. They are our most popular choice and have become the standard among brand owners. In the dynamic landscape of encapsulation, veggie caps have emerged as a reliable and sustainable choice. Their versatility, coupled with the benefits of being plant-based and customizable, makes them a preferred option for many industries. As consumer preferences evolve, HPMC capsules are likely to play a key role in shaping the future of encapsulation technology.
