Additionally, HPMC is resistant to fat and oil, which is particularly advantageous in the food industry. Its film-forming capability allows it to act as a barrier, protecting sensitive ingredients from oxidation and moisture.

The applications of HPMC are vast and varied. In the pharmaceutical industry, it is commonly used as a binding agent in tablets and as a stabilizer in liquid formulations. In construction, HPMC is an essential ingredient in tile adhesives, plasters, and dry mix mortars, where it improves workability and enhances the water retention properties of the materials. The food industry also benefits from HPMC, as it is often used as a thickener and emulsifier in sauces, dressings, and gluten-free products.

Hydroxyethyl cellulose can dissolve in both cold water and hot water, but hot water can accelerate the dissolution process. Generally speaking, it is more appropriate to adjust the water temperature between 40 ° C and 70 ° C. Excessive water temperature may lead to HEC degradation, while excessively low water temperature may slow down the dissolution rate.
