Capsule grade HPMC( 60HL (Ca) ) is especial used for producing Hydroxypropyl methyl Cellulose Plant Capsule. The main component of
traditional gelatin capsule is protein which contains lysine, which will cross-link with aldehyde group, leading to the disintegrating delay of
the 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 spe-
cial hydroxypropyl methyl cellulose, capsule grade hydroxypropyl methyl cellulose has the advantages of low chromium content, high light
transmittance, good whiteness and low ash content. |
