  • Cellulose ether is also widely used in the construction industry as a water-soluble polymer additive in cement-based productscellulose
  • Another benefit of using HPMC is its safety profile. It is generally recognized as safe (GRAS) by the Food and Drug Administration (FDA) for use in food products. In addition, HPMC does not cause any significant side effects when used in pharmaceutical formulations, making it a popular choice among manufacturers.
  • The price of hydroxypropyl methylcellulose (HPMC) powder has been a subject of significant interest within the construction industry due to its widespread use as a key ingredient in various construction products. HPMC is a versatile polymer that imparts several functionalities, including thickening, adhesion, and water retention, making it an essential component in a wide range of applications such as coatings, adhesives, and construction mortars.
  • In the food industry, MHEC-MH is used as a stabilizer and thickener. It helps to prevent syneresis in emulsions and suspensions, maintaining their texture and consistency. The polymer's non-toxic and biodegradable nature also make it an environmentally friendly alternative to traditional synthetic thickeners.
  • Studies have shown that increasing the concentration of HPMC in ethanol can lead to a transition from a clear solution to a turbid state, indicating the formation of aggregates. This is a result of the limited solvation capacity of ethanol for high molecular weight HPMC. Conversely, at lower concentrations, HPMC can dissolve completely in ethanol, forming stable solutions.
  • In the pharmaceutical sector, HPMC is classified as an excipient, meaning it is used as a non-active ingredient in medications. It is commonly found in tablet coatings, acting as a film former providing a protective layer around the pill. Additionally, it is used in capsule production due to its ability to form gels, facilitating the controlled release of active ingredients in the digestive system.
  • In the construction sector, HPMC finds application as a thickener and stabilizer in mortar and plaster. Its water retention properties prevent premature drying, improving workability and durability Its water retention properties prevent premature drying, improving workability and durability Its water retention properties prevent premature drying, improving workability and durability Its water retention properties prevent premature drying, improving workability and durabilityhydroxy methyl cellulose. It also acts as a retarder, slowing down the setting time of cement, providing more flexibility during construction.

  • But, there are some potential disadvantages that are not immediately obvious. HPMC is listed as a food ingredient — E464 — which means that recommended daily maximum quantities must be defined. HPMC undergoes a rigorous manufacturing process involving the synthetic — and not natural — alteration of cellulose. During production, various highly reactive, harmful or toxic substances are used that must be removed and disposed after production, including propylene oxide (which is considered to be carcinogenic) and chloromethane.

  • HPMC is extensively used in various construction materials, such as cement-based mortars, gypsum-based plasters, tile adhesives, and self-leveling compounds. Its water retention and thickening properties are particularly valuable in these applications.

  • In the cosmetic industry, HPMC is used in a variety of personal care products such as creams, lotions, and hair care products. It acts as a thickening agent, emulsifier, and film-former to improve the texture, stability, and shelf life of cosmetic formulations. HPMC is also used in sunscreen products to enhance the protection and water resistance of the sunscreen.
  • HPMC is also prevalent in the construction sector, where it functions as a vital component in the production of wallpaper pastes. Its capacity to form viscous solutions allows for easy application and removal without damaging the underlying surface. Furthermore, HPMC is employed in the manufacture of joint compounds for plasterboards due to its excellent adhesion properties and ease of sanding.
