ProCap™ 90 Capsule ExcipientProCap 90 is a versatile, low cost capsule excipient that can be used with numerous APIs. It exhibits superior flow, uniform particle size, and packing properties, resulting in optimal content uniformity, stability, and dissolution. Compared to traditionally processed Microcrystalline Cellulose, the proprietarily processed amorphous structure of ProCap 90 is designed to increase the surface area by five times and increase the compaction by 30 50%.
