Factors Affecting Water Retention Of HPMC

1. Cellulose ether HPMC addition

The higher the amount of cellulose ether HPMC added, the higher the water retention rate and the better the water retention effect. In the range of 0.25-0.6% added, the water retention rate increases rapidly with the increase of added amount. When the amount of additive increases further, the increasing trend of water retention rate becomes slow.

2. Cellulose ether HPMC viscosity

When the viscosity of HPMC increases, the water retention rate also increases. When the viscosity reaches a certain degree, the increase of water retention rate tends to be flat.

3. Homogeneity of cellulose ether HPMC

Uniform reaction of HPMC, methoxy, hydroxypropoxy uniform distribution, high water retention rate.

4. Cellulose ether HPMC hot gel temperature

High temperature of hot gel and high water retention rate; On the contrary, the water retention rate is low.
