Factors affecting water retention of hpmc products
2023-12-20 11:401. Homogeneity of cellulose etherHPMC
Hydroxypropyl Methyl Cellulose with uniform reaction, methoxy and hydroxypropyl groups are uniformly distributed, and the water retention rate is high.
2. Cellulose ether HPMC thermal gel temperature
The thermal gel has high temperature and high water retention rate; On the contrary, the water retention rate is low.
3. Viscosity of cellulose ether HPMC
When the viscosity of HPMC increased, the water retention rate also increased; When the viscosity reaches a certain degree, the increase of water retention rate tends to be gentle.
4. Addition amount of cellulose ether HPMC
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% of the added amount, the water retention rate increased rapidly with the increase of the added amount; When the addition amount further increases, the increasing trend of water retention rate slows down.
