Product Details

Hydroxypropyl methylcellulose (HPMC), HPMC is white or milky white, odorless and tasteless, fibrous powder or granules, the loss on drying does not exceed 10%, can be dissolved in cold water but not in hot water, slowly in hot water Swells, peptizes, forms a viscous colloidal solution, cools to a solution, and accordingly becomes a gel when heated. It is usually used in pharmaceutical excipients and can be used as thickenerdispersantemulsifier and film-forming agent.
