A New Era of Vegan Capsules: How Does Hydroxypropyl Methylcellulose (HPMC) Break Through the Traditional Gelatin Market?
Capsules, as the second largest oral dosage form after tablets, are quietly influencing the daily health of countless people worldwide. But what exactly is that tiny capsule in your hand made from—animal bones or natural plants? Behind this lies a raw material revolution concerning safety, stability, and sustainable development.
Currently, empty capsules on the market are mainly divided into two categories: traditional gelatin capsules and emerging plant-based capsules. Gelatin capsules are extracted from collagen in animal bones and produced through chemical fermentation; they remain the mainstream product. However, their production process not only requires the addition of various chemical substances but also carries the potential risk of animal-borne infectious diseases, frequently raising concerns about their safety.
In contrast, plant-based capsules, represented by hydroxypropyl methylcellulose (HPMC), are extracted from natural plants and are gradually coming into the spotlight due to their unique "pure genes.":
