HPMC E5 for Empty HPMC Capsules

*It is semi-synthetic in nature, derived from plant cellulose,

*Cross-linking problem with the excipients is totally absent since, the polymer is free from amino acids,

*Can be used for a variety of fill materials containing aldehydic group,

*It readily dissolves in cold water giving a colloidal solution owing to the reversible thermal gelation property,

*Forms a flexible film of controlled dimensions,

*Water does not act as a plasticiser for HPMC.
