The main raw material of this vegetable empty capsule is hypromellose (HPMC), derived from plant cellulose and modified via etherification to form a non‑ionic cellulose ether. The technology is mature, the stability is excellent, and it has long been included in pharmacopoeias of various countries. The raw material is safe and controllable, aligning with the natural attributes of vegetable capsules.

Wide adaptability, stable drug release rate, complete dissolution – helping to achieve more significant efficacy while reducing individual differences, suitable for multiple formulation scenarios. Its high versatility makes it adaptable to various contents such as TCM extracts, Western pharmaceutical preparations, and health foods. The dissolution behavior is uniform, facilitating batch‑to‑batch consistency. The low moisture content (typically 5‑8%) makes the capsule shell less prone to brittleness in dry environments, while also performing well under higher humidity, making it more friendly to moisture‑ and heat‑sensitive contents. Additionally, the production process and technology maturity are high, and it is widely used in pharmaceutical and cross‑border registration systems. It has no chemical residues and excellent microbial control, meeting relevant requirements for pharmaceutical excipients.

Especially suitable for vegetarians and religious groups such as Muslims, Jews, and Hindus, meeting diverse consumer needs.

No preservatives added; no sterilization required before shipment, no ethylene oxide residue, meeting safety compliance standards.
