  • Introduction
  • HPMC is commonly used in the construction industry as a thickener, binder, and water retention agent in cement-based materials. The grade of HPMC used in construction typically has a high viscosity, which helps improve workability and bonding strength of the mortar or concrete. Additionally, HPMC can also be used as a film former in coating materials, protecting the surface from moisture and chemicals.
  • Fertigpräparate als „künstliche Tränen“ (Auswahl):

  • Application: Hydroxypropyl methylcellulose can be used in coatings, ceramics, printing inks, plastics. HPMC has construction grade, food grade, and pharmaceutical grade according to the application. The construction industry is the most widely used application for MELACOLL hydroxypropyl methylcellulose.

  • DS: the substituent of HPMC is Hydroxypropyl and Methoxy. The ratio of them affects HPMC properties. The higher the hydroxypropyl content, the better the water retention effect. The lower the methoxy content, the higher the gel temperature. The DS of HPMC is 1.2-2.0. But HEC substituent is Hydroxyethyl substituent. Its DS is 1.5-2.0.

  • Why is Hydroxypropyl Methylcellulose in Construction?

  • If you think there has been an overdose, call your poison control center or get medical care right away. Be ready to tell or show what was taken, how much, and when it happened.
  • 1. Quality The quality of hydroxyethyl cellulose is determined by its degree of substitution (DS), which refers to the number of hydroxyl groups in the cellulose molecule that have been replaced by hydroxyethyl groups. Higher DS values generally indicate higher viscosity and better performance, which can result in higher prices.
  • The global redispersible polymer powder market has been witnessing a significant upsurge in recent years, driven by its extensive application across various industries. This innovative product, a specialized form of polymer, is known for its unique property of re-dispersion, making it an essential ingredient in numerous construction and chemical applications.
  • What is HPMC used for?
    It is most frequently utilized in vegan-friendly products as a gelatin and gluten substitute. HPMC can be used as toothpaste, mouthwash, and other oral care products and cosmetics. It acts as a moisturizer on the skin, but it's not approved to be used in that capacity by the FDA. HPMC is used in medicine to help prevent or treat diarrhea caused by certain antibiotics or other medications. It can also be used as an ointment for wounds or burns because it provides relief from pain and healing without leaving behind any scarring or discoloration.

  • Lastly, HPMC plays a role in the energy sector, particularly in the production of lithium-ion batteries. Its unique properties allow it to serve as a binder in the cathode material, enhancing battery performance and durability.
  • 1. Floor and Wall Tiling HPMC provides a reliable and durable adhesive for floor and wall tiles, ensuring a seamless and waterproof installation.
  • For starters, HEC is a white, odorless, and tasteless powder that dissolves readily in cold or hot water, forming a clear, viscous solution. Its non-ionic nature means it is not affected by the presence of salts or pH changes, making it exceptionally stable in various formulations. These attributes make HEC an ideal thickener, stabilizer, emulsifier, and film-former in products ranging from cosmetics and personal care items to construction materials and even food.
  • The versatility of redispersible polymer powders extends beyond their applications in construction and adhesives
  • Measures to Ensure HPMC Safety
  • Derived from natural cellulose, HEC is a nonionic, water-soluble polymer that offers exceptional thickening, suspending, and stabilizing capabilities. Its versatility stems from its ability to function effectively in both acidic and alkaline environments, making it suitable for a wide range of applications. Ashland's expertise in HEC production ensures high-quality products with consistent performance, tailored to meet specific customer needs.
  • In the cosmetics sector, HPMC is used in different grades depending on the product. Low to medium viscosity grades are used in lotions and creams for their emulsifying abilities, while higher viscosity grades can be found in hair care products for their ability to create a rich, creamy texture.

  • The FEEDAP Panel agrees with the approach of the ANS Panel that, although the data set available for the different celluloses is not complete and most of the studies were old and do not meet the current requirements of toxicological testing, the physico-chemical, structural, biological and kinetic similarities between the modified celluloses make it possible to apply a read-across approach among the different celluloses. Overall, the available information allows to conclude that the celluloses (as a group) are of low toxicological concern.
