Factors that affect water retention of hypromellose HPMC products

The water retention of hypromellose HPMC products is often affected by the following factors: 1. Cellulose ether HPMC homogeneously reacted with HPMC, methoxy, hydroxypropyl homogeneously distributed, high water retention rate. 2. Cellulose ether HPMC thermogel temperature, thermogel temperature, high water retention rate, on the contrary, low water retention rate. 3. When the viscosity of cellulose ether HPMC increased, the water retention rate also increased, and when the viscosity reached a certain degree, the water retention rate increased gradually. Four. The more the cellulose ether HPMC was added, the higher the water-holding rate was, and the better the water-holding effect was. In the range of 0.25-0.6% , the water retention rate increased rapidly with the increase of the addition amount.
