Single-phase gels encompass organic and natural macromolecules uniformly dispersed all over a liquid in this kind of manner that no apparent boundaries exist between the dispersed macromolecules along with the liquid. One-period gels might be made from synthetic macromolecules (e.
Lubricants cut down friction in the compression and ejection cycle. Additionally, they assist in protecting against adherence of pill product to the dies and punches. Metallic stearates, stearic acid, hydrogenated vegetable oils, and talc are used as lubricants. Due to mother nature of this operate, most lubricants are hydrophobic, and as a result usually decrease the charges of pill disintegration and dissolution.
