  • The solubility of HPMC in organic solvents is relatively low, but this property is utilized in certain applications where water resistance is desired, like in the production of water-resistant coatings or films.
  • One of the key properties of HPMC is its ability to form gels in water. This makes it an excellent choice for thickening liquids, such as sauces, soups, and cosmetics. When HPMC is added to a liquid, it absorbs water and swells, creating a gel-like texture. The thickness and viscosity of the gel can be adjusted by varying the concentration of HPMC in the liquid.
  • Tell your doctor and pharmacist about all of your drugs (prescription or OTC, natural products, vitamins) and health problems. You must check to make sure that it is safe for you to take hydroxypropyl methylcellulose with all of your drugs and health problems. Do not start, stop, or change the dose of any drug without checking with your doctor.

  • Celotech offers a wide range of Celopro® construction grades to ensure that for every conceivable situation the right product is available.

  • The process of manufacturing HPMC involves treating cellulose with a mixture of alkali and a propylene oxide-methanol blend. This reaction replaces some of the hydroxyl groups on the cellulose backbone with hydroxypropyl and methyl groups, altering its properties significantly. The hydroxypropyl group enhances water solubility, while the methyl group imparts stability and improves the interaction with other materials.
  • The Role of HPMC in Building Coatings and Adhesives
  • The pharmaceutical industry also makes use of HPMC in tablet coatings, controlled-release formulations, and eye drops. The viscosity of HPMC can be tailored to provide the desired release profile and drug delivery characteristics, ensuring the effectiveness of the medication.
  • The percentage of HPMC in a formulation can significantly influence the drug delivery system
  • Dow Inc., an American multinational chemical corporation, offers its own line of redispersible polymer powders under the Dowsil brand. These products are known for their exceptional performance in waterproofing, tile adhesives, and repair mortars. Dow's advanced R&D capabilities enable them to continually develop new formulations to meet evolving industry demands.
  • In the pharmaceutical sector, HEC serves as a binder, disintegrant, and viscosity enhancer in tablet formulations
  • In the cosmetics industry, HPMC is used in a variety of products such as creams, lotions, and sunscreens. It is added to formulations to improve their consistency, stability, and spreadability. HPMC is also used in hair care products, such as shampoos and styling gels, to provide a smooth and silky texture. In skincare products, HPMC helps to create a protective barrier on the skin, locking in moisture and enhancing the overall effectiveness of the product.
  • The majority of the available studies have been performed in rats, just few of them in rabbits and dogs. Among those meeting the current criteria for toxicological testing, the no observed adverse effect level (NOAEL) values for the different modified celluloses were identified most often corresponding to the highest tested level or changes in body or organ weights. For microcrystalline cellulose (E 460) the identified NOAELs in rats ranged from 3,769 mg/kg body weight (bw) per day to 9,000 mg/kg bw per day and in all cases corresponded to the highest levels of the test substance. For methyl cellulose (E 461), the dose level of 3% in rats (equivalent to 2,700 mg/kw bw per day) was selected as the NOAEL based on a decrease in body and organ weight displayed in male rats administered with the top additive level (10%, equivalent to 9,000 mg/kg bw per day and day).

  • Conclusion
  • Another important application of HPMC is as a stabilizer in emulsions and suspensions. HPMC can prevent particles from settling out of a solution, ensuring uniformity and stability over time. This is crucial in industries such as the food and beverage industry, where emulsions and suspensions are commonly used in products such as salad dressings, sauces, and beverages.
  • One of the key benefits of using HPMC in pharmaceutical formulations is its ability to control drug release. By adjusting the viscosity and molecular weight of the HPMC, manufacturers can fine-tune the rate at which the drug is released into the body. This is particularly useful for drugs that need to be released slowly over an extended period, such as those used to manage chronic conditions like arthritis or diabetes This is particularly useful for drugs that need to be released slowly over an extended period, such as those used to manage chronic conditions like arthritis or diabetes This is particularly useful for drugs that need to be released slowly over an extended period, such as those used to manage chronic conditions like arthritis or diabetes This is particularly useful for drugs that need to be released slowly over an extended period, such as those used to manage chronic conditions like arthritis or diabeteswhat does hpmc stand for.
  • Da HPMC ein Abkömmling der natürlichen Cellulose ist, ist HPMC vegan. Somit können Menschen, die sich vegan oder vegetarisch ernähren oder aufgrund ihrer Religion auf Gelatine verzichten, bedenkenlos zu HPMC-Kapseln greifen.

  • In addition to its use in tablets, HPMC is also used in ophthalmic solutions, ointments, and suspensions. In these formulations, HPMC acts as a viscosity enhancer and stabilizer, helping to improve the shelf life and consistency of the product. It is also used in topical creams and gels to provide a smooth and creamy texture that is easy to apply to the skin.
  • Moreover, HPMC imparts improved adhesion to the gypsum plasterhpmc for gypsum plaster. It allows the plaster to form a stronger bond with various substrates, including brick, wood, and concrete. This enhanced adhesion prevents delamination and prolongs the lifespan of the plaster by resisting the forces that could lead to peeling or flaking over time.
  • In the field of textiles, HPMC is employed in the printing and dyeing process, improving colorfastness and fabric quality. It is also used in the paper industry to enhance paper strength and printability.
