Introduction of Hydroxypropyl Starch and Capsules
Hydroxypropyl Starch hollow capsules are the most promising substitutes of Gelatin capsule and they have been included in the Chinese Pharmacopoeia (2015 Edition) Due to the complex structure and properties of starch, the research and development of the starch capsule technology is extremely difficult. To solve the problem, our company applies the modification of the starch molecular structure, and successfully solving the challenge of moisture and flexibility factors. As a result the hydroxyproply starch flexibility and water retention ability of the capsules can be improved significantly. For all key indexes such as uniformity, transparency, tightness, friability, disintegration time limit, drying time, our products are better than or at least equal to the relevant Chinese Pharmacopoeia (2015 Edition) standard. Also, the breakage rate in pharmaceutical filling test is lower than 0.1%; The hydroxypropyl starch also can use the molding method to produce soft capsules. In summary its quality price ratio is far superior than the current Gelatin capsules and Alginate capsules.
