What causes hydroxy propyl methyl cellulose to be affected?

The hydroxy propyl methyl cellulose product itself will be affected by the following four reasons, as follows, for reference only.

First, the water retention of hydroxypropyl methyl cellulose will be affected by the viscosity

When the viscosity of hydroxypropyl methyl cellulose rises, its water retention rate will also rise. When the viscosity reaches a certain degree, the increase of water retention rate tends to be flat.

Two, the water retention of hydroxypropyl methyl cellulose will be affected by the amount of addition

Generally speaking, the higher the amount, the higher the water retention rate, the better the water retention effect. In the range of 0.25-0.6% of the addition amount, the water retention rate increases with the increase of the addition amount. When the addition amount was further added, the trend of water retention rate was slowed down.

Three, hydroxypropyl methyl cellulose water retention will be affected by hot gel temperature
In general, the higher the temperature of hot gel, the higher the water retention rate. On the contrary, the hot gel temperature, the water retention rate is low.

Four, hydroxypropyl methyl cellulose water retention will be affected by uniformity

Homogeneous reaction of hydroxypropyl methyl cellulose, methoxy, hydroxypropoxy evenly distributed, high water retention rate.
