  • Raw Materials


  • 1: What is HPMC?
    Hydroxypropyl methylcellulose ( (Propylene glycol ether of methylcellulose) is a methylcellulose modified with a small amount of propylene glycol ether groups attached to the anhydroglucose of the cellulose. The dry product contains 19 to 30 per cent of methoxyl (-OCH3) groups and 3 to 12 per cent of hydroxypropyl (-OCH2CHOHCH3) groups. HPMC can be derived from tree fiber or cotton fiber.

    2: How HPMC is made:
    The cellulose ethers are manufactured by a reaction of purified cellulose with alkylating reagents (methyl chloride) in presence of a base, typically
    sodium hydroxide and an inert diluent. The addition of the base in combination with water activates the cellulose matrix by disrupting the crystalline structure and increasing the access for the alkylating agent and promotes the etherification reaction. This activated matrix is called alkali cellulose (Kirk-Othmer, 1993). During the manufacture of HPMC alkali cellulose reacts with methyl chloride to produce methyl cellulose and sodium chloride. Side reactions of the methyl chloride and sodium hydroxide produce methanol and dimethyl ether by-products. The methylcellulose is then further reacted with the staged addition of an alkylene oxide, which in the case of HPMC is propylene oxide (Kirk Othmer, 1993 Dow, 2002). After this reaction, MC and HPMC are purified in hot water, where they are insoluble. Drying and grinding completes the process.

    3: Chemicals agents and reactions:
    The chemical reactions of manufacturing HPMC summerize as following:
  • To prepare HPMC gel, one must first dissolve HPMC powder in water. This can be done by adding the powder slowly to water, while stirring continuously to prevent clumping. The mixture is then allowed to hydrate and swell for a period of time, typically a few hours, until a gel-like consistency is achieved. This process is known as the gel hydration process.
  • 1. Weighing the HPMC Start by accurately weighing the desired amount of HPMC powder. The concentration usually ranges from 1% to 5%, depending on the application. For example, a 2% solution can provide satisfactory thickening properties for many formulations.
