Dissolution method of hydroxypropyl methylcellulose (HPMC)

Dissolution method of hydroxypropyl methylcellulose (HPMC)

Hydroxypropyl methylcellulose (HPMC) is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textiles, agriculture, cosmetics, tobacco and other industries. Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processes. Hydroxypropylmethylcellulose (HPMC) is an odorless, tasteless, non-toxic white powder that can be dissolved in cold water to form a transparent viscous solution. It has the characteristics of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, maintaining moisture and protecting colloid.

The dissolution method of hydroxypropyl methylcellulose (HPMC):

This product swells and disperses in hot water above 85°C, and is usually dissolved by the following methods:

1. Take 1/3 of the required amount of hot water, stir to completely dissolve the added product, and then add the rest of hot water, which can be cold water, or even ice water, and stir until the appropriate temperature (20°C), then it will be completely dissolve. the

2. Dry blending and mixing:

In case of mixing with other powders, it should be fully mixed with the powders before adding water, then it can be dissolved quickly without agglomeration. the

3. Organic solvent wetting method:

First disperse the product in an organic solvent or wet it with an organic solvent, and then add it to cold water to dissolve it well.
