Products Description
Headcel HPMC for Plant capsules
Headcel HPMC for Plant capsules are especial used for producing Hydroxypropyl methy! Cellulose Plant Capsule. The main component of traditional gelatin capsule is protein which contains lysine, which wil cross-ink with aldehyde group, leading to the disintegrating delay other drug wrapped in gelatin eventually, However, part of methyl group and part of hydroxypropyl ether of HPMC have stable chemical properties and will not occur crosslinking, effectively reducing the disintegration delay caused by crosslinking. Compared with other special hydroxypropyl methyl cellulose, capsule grade hydroxypropyl methyl cellulose has the advantages of low chromium content, high light transmittance, good whiteness and low ash content.
