hpmc powder-How to dissolve hydroxypropyl methylcellulose (HPMC)

hpmc powder-How to dissolve hydroxypropyl methylcellulose (HPMC) Hot water dissolution method: Since hpmc does not dissolve in hot water, hpmc can be uniformly dispersed in hot water at the initial stage, and then quickly dissolve during cooling. Two typical methods are described as follows: 1) Put the required amount of hot water in the container… Continue reading hpmc powder-How to dissolve hydroxypropyl methylcellulose (HPMC)

hpmc power-Why control the balance of hydroxypropyl and methoxy groups in HPMC products?

hpmc power-Why control the balance of hydroxypropyl and methoxy groups in HPMC products? The ratio of HPMC’s hydroxypropyl value to methoxy value has a great influence on the water solubility, surface activity and gel temperature of the product. If the methoxy value is high and the hydroxypropyl value is low, the water solubility and surface… Continue reading hpmc power-Why control the balance of hydroxypropyl and methoxy groups in HPMC products?
