Products Description of Hydroxypropyl Methyl Cellulose CAS#9004-65-3

Hydroxypropyl methylcellulose (HPMC) is a propylene glycol ether derivative of methylcellulose, where hydroxypropyl and methyl groups are attached to the anhydrous glucose units of cellulose through ether bonds. It appears as a white to off-white powder or granules and shares properties with methylcellulose, being soluble in cold water but insoluble in hot water. Its solubility in organic solvents surpasses that in water, dissolving readily in anhydrous methanol and ethanol, as well as in chlorinated hydrocarbons and ketones. In cold beverages, HPMC can be used alone or combined with other emulsifiers and stabilizers. Over the years, it has found widespread applications across the petrochemical, paper, leather, textile printing and dyeing, pharmaceutical, food, and cosmetic industries, serving as a dispersant, thickener, adhesive, excipient, capsule material, oil-resistant coating, and filler.

Product Usage

Hydroxypropyl methylcellulose (HPMC) finds extensive applications across multiple industries. In construction, it is used as an additive to improve material performance. In the pharmaceutical sector, it serves as an excipient and binder. In the food industry, HPMC functions as a water-retaining agent in baking, a stabilizer for frozen products, and a thickener for beverages. In the daily chemical industry, it is employed as a thickener in cosmetics and as an anti-redeposition agent in detergents. Additionally, it is widely used in papermaking for sizing, in textile processing for fabric sizing, and in ceramics for bonding and shaping ceramic materials.
