  • 5. Controlled Release In the pharmaceutical field, HPMC is utilized in controlled-release formulations, allowing for sustained release of active ingredients over time.


  • Hydroxypropyl Methylcellulose is globally known as “Hypromellose” and manufactured by chemically made polymer cellulose. It is considered safe for normal human consumption and is commonly used as an option instead of gelatin because of its vegetarian source and its physical appearance to gelatin.

  • Another significant application of HPMC is in the construction industry, where it is incorporated into cement-based products such as mortars, plasters, and adhesives. HPMC enhances the workability of these materials, allowing for easier application and improving adhesion to substrates. Furthermore, HPMC improves water retention in mortars, which is critical for ensuring proper hydration during the curing process. This application is particularly valuable in regions with hot and arid climates where rapid evaporation can compromise the strength and durability of construction materials.


  • Apart from the aforementioned industries, HPMC is also used in various applications such as 3D printing, oil drilling, and as an additive in various industrial processes. Its flexibility and adaptability make it a valuable component in numerous formulations, where performance and efficiency are critical.


  • The significance of liquid thickeners extends beyond mere texture enhancement. They contribute to the overall quality and acceptability of food products. With the rising consumer demand for healthier options, thickeners can help reduce fat and calorie content by providing creaminess without added fats.


  • The food industry also benefits significantly from HPMC, where it is used as a food additive to enhance texture, stability, and shelf-life. It helps improve the viscosity of sauces and dressings while also acting as a fat replacer in low-fat products. Its application in the food sector highlights HPMC's safety and regulatory acceptance, making it a preferred choice amongst food manufacturers globally.

  • HEC, derived from cellulose through ethylene oxide treatment, is characterized by its hydroxyethyl groups which impart hydrophilic properties. This structure enhances its solubility in water, making it an effective thickener in aqueous formulations. HEC is known for its ability to form gels and create a smooth texture, making it suitable for cosmetic products like lotions and creams.


  • HPMC has many applications across various industries due to its unique properties. One of its main uses is in the pharmaceutical industry, where it is used as a thickener, stabilizer, and film former in tablet coatings, capsules, and ointments. HPMC is inert and has a low risk of causing allergic reactions, making it a safe option for pharmaceutical products.


  • - Mortars VAE redispersible powders improve the flexibility and adhesion of tile adhesives and renovation mortars, allowing for better performance in demanding conditions such as moisture-rich environments.

  • 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:
