Hydroxylmethylcellulose HPMC water retention is an important indicator of application, and what factors affect the water retention of hydroxypropyl methylcellulose HPMC, we may wish to learn more:
The water retention of hydroxypropyl methylcellulose HPMC products is often affected by the following factors:
Cellulose ether HPMC uniformity
The homogeneously reacted HPMC has a uniform distribution of methoxy and hydroxypropoxy groups and a high water retention rate.
Cellulose ether HPMC thermogel temperature
The thermal gel has a high temperature and a high water retention rate; on the contrary, the water retention rate is low.
Cellulose ether HPMC viscosity
When the viscosity of HPMC rises, the water retention rate also rises; when the viscosity reaches a certain level, the increase of the water retention rate tends to be gentle.
Cellulose ether HPMC addition
The larger 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%, the water retention rate increases rapidly with the increase of the addition amount; when the addition amount further increases, the increase rate of the water retention rate becomes slower.
The SLEO hydroxypropyl methylcellulose HPMC produced by ZiQian has the characteristics of good uniformity, high thermal gel temperature, good water retention and low addition, which can effectively improve the application effect of hydroxypropyl methylcellulose HPMC.
