How to choose the right hydroxypropyl methylcellulose

The relationship between water retention and viscosity of hydroxypropyl methylcellulose is not a proportional relationship within a certain viscosity range, but also depends on the practical application of the product. Relatively speaking, when hydroxypropylmethylcellulose has a viscosity of more than 100,000, the difference in water retention between 100,000 viscosity and 200,000 viscosity is not large. [...]
