hydroxyéthyl celluloseThe concentration of HEC also plays a critical role in solubility. At lower concentrations, HEC dissolves easily, whereas at higher concentrations, it can lead to an increase in solution viscosity that may impede further dissolution. This phenomenon is particularly important for formulators; they must carefully balance the concentration of HEC to achieve the desired viscosity without compromising solubility.
hydroxyethyl cellulose solubility in waterWhat Does HPMC Stand For?
An aqueous solution of HEC is a non-Newtonian fluid, and its viscosity changes as the shear rate changes.
The viscosity increases as the shear rate decreases, while the viscosity decreases as the shear rate increases (thixotropy).
The thixotropy of an aqueous solution of HEC increases with higher viscosity products with higher molecular weight, and decreases with lower viscosity products. Low-viscosity products have very low thixotropy and exhibit characteristics similar to Newtonian fluids.In conclusion, RDP powder serves as a critical component in numerous applications, primarily within the construction and coatings industries.
