How to dissolve HPMC(Hydroxypropyl Methyl Cellulose) correctly? What is the specific methods?

HPMC can be divided into instant type (Surface treated) and hot soluble type (Non-surface treated). The instant product is rapidly dispersed in cold water and disappears into the water. At this time, the liquid has no viscosity because HPMC is only dispersed in water and there is no real dissolution. About 2 minutes, the viscosity [...]
