คำถาม
When using the hot water diffusion method to dissolve HPMC (Hydroxypropyl Methylcellulose, 5000 cP, 68C Gel), what proportion of the total water should be heated for dispersion (80-90°C) versus the portion that should be cold (ideally no more than 20°C) for final dissolution?

Dissolving HPMC (Hydroxypropyl Methylcellulose, 5000 cP, 68C Gel) using the Hot Water Diffusion Method
To dissolve HPMC using the hot water diffusion method, the process involves two main steps:
- Disperse in Hot Water: Disperse the HPMC powder in hot water heated to 80-90°C. Stir until the powder is completely dispersed, which will result in a turbid liquid.
- Dissolve in Cold Water: Add this turbid liquid dispersion to the remaining cold water (ideally no more than 20°C). Continue stirring until a clear gel texture is achieved.
The product description explains this method, noting that the total water is divided into a hot portion for dispersion and a cold portion for final dissolution. However, the description does not specify the exact proportion or ratio of hot water to cold water to be used.
