HPMC E5 is a low-molecular-weight hydroxypropyl methylcellulose (HPMC) that is used as a thickening, suspending, and emulsifying agent in a variety of products. It is a white, odorless, tasteless powder that is soluble in cold water and insoluble in hot water. It is used in a variety of applications, including food, pharmaceuticals, and cosmetics.
The viscosity of HPMC E5 is typically measured in centipoise (cP). This is a measure of the resistance of a liquid to flow, and is expressed as the amount of pressure required to move a given volume of liquid at a given speed. The viscosity of HPMC E5 can range from 4 to 6 cP, depending on the concentration of the solution and the temperature.
At a concentration of 1%, the viscosity of HPMC E5 is typically around 5 cP. At a concentration of 2%, the viscosity increases to around 5 cP. At a concentration of 3%, the viscosity increases to around 5 cP. At a concentration of 4%, the viscosity increases to around 5 cP.
In summary, the viscosity of HPMC E5 can range from 1 to 100,000 cP, depending on the concentration of the solution, the temperature, and the pH. At a concentration of 1%, the viscosity is typically around 5 cP. At higher concentrations, the viscosity increases, and at higher temperatures and higher pH levels, the viscosity also increases.
