HPMC E6 FG

KimaCell^®HPMC E6 FG Hydroxypropyl methylcellulose has thermoreversible gelling properties.

Hydroxypropyl methylcellulose must be dissolved in cold water or normal temperature water. When the aqueous solution is heated, the viscosity will continue to decrease, and gelation will occur when it reaches a certain temperature. At this time, the transparent solution of HPMC begins to It becomes milky white and opaque, and the apparent viscosity increases rapidly. This temperature is called the thermal gel initiation temperature. As the gel cools, the apparent viscosity drops rapidly. Finally, the viscosity curve when cooling is consistent with the initial heating viscosity curve, the gel turns into a solution, the solution turns into a gel when heated, and the process of turning back into a solution after cooling is reversible and repeatable. Hydroxypropyl methylcellulose has a higher thermal gelation onset temperature than methylcellulose and a lower gel strength.
