Can Hydroxypropyl Methylcellulose still be used after getting wet?

Hydroxypropyl methylcellulose(HPMC) is a commonly used functional polymer compound. Hydroxypropyl methylcellulose may change its performance and quality due to moisture during our use. So can hydroxypropyl methylcellulose still be used when it gets wet?

First, we need to find the cause of moisture in hydroxypropyl methylcellulose. Improper storage and humid environments are one of the main causes of moisture in hydroxypropyl methylcellulose. The use of poor quality bags may cause moisture in the air to penetrate the product. Prolonged exposure to high humidity may cause the product page to absorb moisture.

Hydroxypropyl methylcellulose may agglomerate when exposed to moisture, resulting in a powder that is no longer homogeneous and difficult to disperse. This can affect the effectiveness of the use of hydroxypropyl methylcellulose, and may also lead to a decrease in the viscosity of the product and a change in solubility, which may affect the performance in various applications.

So, can you use hydroxypropyl methylcellulose when it gets wet? It depends on the situation. For products that are slightly damp, there are ways to restore them. For example, drying the damp product to remove excess moisture. The powder can also be re-homogenized by mixing equipment. In the case of severely damp hydroxypropyl methylcellulose, the probability is that agglomeration has occurred and its performance will be affected. In this case, it is recommended not to continue using these severely dampened products to avoid adverse effects on the final application.
