Quali-V® meets the pharmaceutical requirements for two-piece hard capsules ●
Quali-V® capsules are made from plant derived hypromellose. This has been used extensively in oral solid dosage forms for many years. It is chemically stable and is compatible with most pharmaceutical materials.
Quali-V® capsules does not undergo cross-linking reactions like gelatin and assures encapsulated products with good dissolution.
Quali-V® capsules have the required strength and dimensions that enable them to be filled and packaged on automatic high-speed machines.
Quali-V® capsules meet the exacting requirements for a pharmaceutical-grade hard two-piece capsule.

Additional benefits of Quali-V® capsules ●
Filling performance comparable to gelatin two-piece capsules.
Patented composition and manufacturating process.
Registered DMF’s in USA & Canada.
Complies with requirements of JP, PhEur and USP/NF.
Available in a variety of sizes and colours.
Physical Stability Benefits Quali-V速 capsules have a lower moisture content, 4.0% to 6.0%, than gelatin capsules. They can be filled with many types of formulations: powders, pellets, tablets, semi-solids and non-aqueous liquids. Quali-V速 capsules maintain their physical stability when filled with hygroscopic materials or exposed to low humidity conditions. Quali-V速 capsules are particulary suited to use in dry powder inhalers because they can be cut and punctured cleanly without shedding particles.

Product Dissolution Quali-VÂŽ capsules have a patented formulation. Hypromellose solutions are converted into a gelling system by the addition of carrageenan and potassium chloride. They are manufactured by the same process as used for hard gelatin capsules. Carrageenan is soluble at low acid pHs giving good dissolution at a range of pH.

Comparative Dissolution The composition of hypromellose capsules is dependent on the manufacturer: each has patented compositions. Quali-V® capsules are the only ones that use carrageenan. Carrageenan is the only gelling agent soluble at pH < 4. Quali-V® capsules made by our patented process have a solubility profile different to other manufacturers’ capsules. Hypromellose capsules from 3 different suppliers for the Japanese market were tested and the results are shown below. Dissolution of acetaminophen from hypromellose capsules in acid medium (pH 1.2)
