For instance, low viscosity HPMC may be chosen for applications requiring a thin solution that flows easily, such as in sprayable formulations. Conversely, high viscosity grades are favored in products like gels and creams, where a thicker consistency is required to enhance stability and texture.

The paint and coatings industry extensively utilizes RDP powder to improve the performance of emulsion paints. The powder contributes to better flow, leveling, and gloss properties, which are essential for ensuring a smooth, aesthetically pleasing surface. Furthermore, RDP helps in optimizing the drying time of paints, offering a quicker turnaround for projects, which is particularly beneficial in commercial settings.

DEFINITION Hydroxypropyl methyl cellulose is a methyl cellulose modified by treatment with alkali and propylene oxide by which a small number of 2-hydroxypropyl groups are attached through ether links to the anhydroglucose units of the cellulose. The article in commerce may be further specified by viscosity.
