Audited Supplier Soluble hydroxypropyl methylcellulose has good cold and hot water dissolution performance, different products have different dissolution properties. Hydroxypropyl methyl cellulose often exhibits pseudoplastic behavior, that is, shear thinning. This change does not happen immediately, but is a gradual process, requiring continuous application of shear force before the viscosity decreases.
Most of the hydroxypropyl methyl cellulose is highly plastic, and it can be turned into a viscous liquid by speeding up the stirring.
The repulsion between carboxyl groups will also be weakened at pH = 12, because the presence of alkali metal cations causes the molecular chains to curl up, reducing the viscosity of the solution. Therefore, the viscosity of HPMC also depends on its pH. When PH = 5.0-8.5, the viscosity of HPMC can show the maximum value.
