8.Solubility: soluble in water and some organic solvents, such as appropriate proportion of ethanol/water, propanol/water, dichloroethane, etc. Water soluble the liquid has surface activity, high transparency and stable performance. Different specifications of the product gel temperature is different, this is the HPMC thermal gel properties. The solubility varies with the viscosity. The lower the viscosity, the greater the solubility. The performance of HPMC of different specifications varies to some extent.
