  • HPMC, or Hydroxypropyl Methyl Cellulose, is a versatile and widely used thickening and binding agent in various industries. It is essential for creating a smooth texture, improving suspension, and extending the shelf life of products. This article provides a comprehensive guide to HPMC for sale, including its properties, uses, and factors to consider when purchasing it.
  • Hydroxypropyl methylcellulose, also known as HPMC, is a highly versatile polymer that is used in a wide range of industries. It is a modified form of cellulose that has been chemically altered to improve its properties and performance. HPMC is commonly used as a thickener, emulsifier, and stabilizer in food products, pharmaceuticals, and cosmetics.
  • In the construction industry, HPMC is a common additive in building materials like plaster, mortar, and drywall compounds. It acts as a thickener, improving the workability of these materials and aiding in their setting time. Its water retention capabilities prevent premature drying, ensuring a quality finish.
  • In conclusion, hydroxyethyl cellulose is a versatile polymer with unique thickening properties that make it a valuable ingredient in a wide range of industries. Its viscosity, which is determined by its concentration in a solution, plays a key role in the performance of products. By understanding and controlling the relationship between hydroxyethyl cellulose concentration and viscosity, manufacturers can create high-quality products that meet the needs of consumers.
  • The packaging sector benefits from VAE powder's ability to create heat-sealable films with excellent barrier properties. These films protect food and other products from moisture, oxygen, and UV light, extending their shelf life. Furthermore, VAE-based adhesives provide strong bonds between different materials, making them suitable for carton sealing and label manufacturing.
  • The percentage of HPMC in a formulation can significantly influence the drug delivery systemhypromellose hpmc. Low viscosity grades are often used for immediate-release formulations, while high viscosity grades contribute to controlled or extended-release mechanisms. The precise ratio of HPMC to other ingredients is carefully calculated to achieve the desired pharmacokinetic profile.
  • HEC is considered hypoallergenic, which means it is less likely to cause allergic reactions in users. This makes it a safe choice for people with sensitive skin or allergies.
  • MHEC is also utilized in the food industry, albeit in a limited capacity due to strict regulations. It serves as a food-grade emulsifier and thickener, enhancing the texture and stability of certain products like ice cream and salad dressings.
  • Furthermore, re-dispersible polymer powder also improves the durability of cement-based materialsre dispersible polymer powder. The film formed on the surface of the mixture provides a barrier against chemical attacks, such as those caused by salts and acids. This makes the material more resistant to corrosion and erosion, extending its lifespan in harsh environments.
  • In the food industry, HPMC is used as a food additive to improve the texture, shelf life, and stability of various products. Its solubility in water allows HPMC to form gels and films that can enhance the mouthfeel of foods such as baked goods, dairy products, and sauces. HPMC can also act as a thickener and stabilizer in food products, helping to maintain their quality and consistency.
  • What Is an HPMC Distributor?
  • HPMC is also used in the personal care and cosmetics industry. It is found in a wide range of products, including lotions, creams, shampoos, and mascaras. HPMC acts as a film former, thickener, and emulsifier in these products, enhancing their stability, texture, and performance. It can also be used to create environmentally friendly and natural formulations in cosmetics.
  • Properties of HPMC
  • In the pharmaceutical industry, HPMC is used as a binder, disintegrant, and film-forming agent. It is commonly used in the production of tablets, capsules, and oral suspensions. HPMC helps to bind the active ingredients together, ensuring that they are released slowly and consistently in the body. It also helps to improve the disintegration of tablets and capsules, making them easier to swallow.
  • In the construction industry, HPMC serves as a key ingredient in dry mixes like tile adhesives, plasters, and mortar. It improves workability, water retention, and sets the setting time, ensuring a smooth and durable finish. For this purpose, one would typically look for HPMC grades with high viscosity and good film-forming capabilities.
  • Lastly, in paint manufacturing, MHE C-MHEC acts as a protective colloid that improves the flow and leveling properties of paints. It helps to create a uniform finish by reducing brush marks and improving spray atomization. Additionally, it increases the adhesion strength between the paint layer and the surface being coated, resulting in longer-lasting durability.
  • When it comes to buying HPMC, the first step is to determine your specific requirements. Different grades of HPMC are available, each tailored for specific applications. For instance, pharmaceutical grade HPMC is highly purified and used in tablet coatings and controlled drug release systems, while construction grade HPMC is used as a binder in plaster and mortar.
  • HEC is derived from cellulose, a natural polymer found in plants, and is produced by reacting cellulose with ethylene oxide to introduce hydroxyethyl groups onto the cellulose backbone. This modification increases the polymer's solubility in water and makes it suitable for various applications.
  • 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.
  • Do not use if the solution is cloudy, leaking, or has particles.

  • For hydroxypropyl cellulose (E 463), the identified NOAEL corresponded to the highest dose 6,000 mg hydroxypropyl cellulose/kg bw per day (by gavage). The most relevant feeding studies with HPMC (E 464) were performed in rats which tolerated up to 10%, corresponding to 9,000 mg test item/kg bw per day. Rabbits tolerated up to 7,500 mg HPMC/kg bw per day administered via the diet (30 day exposure) and dogs up to 1,500 mg HPMC/kg bw per day, in either case being the highest tested dosages. More studies were conducted using sodium carboxy methylcellulose (E 466). The most relevant ones were conducted in rats, with NOAEL values ranging from 4,500 to 9,000 mg test item/kg bw per day (in all cases the highest dose tested). In these studies, some effects (caecum and colonic enlargement, urothelial hyperplasia, nephrocalcinosis, diffuse epithelial hyperplasia in the urinary bladder) were observed, however, not considered of toxicological concern: the findings in the gastrointestinal tract were considered to be a consequence of the accumulation of poorly absorbed water-soluble material and the findings in kidneys and urinary bladder were attributed to the up to fourfold higher concentration of sodium in the test diet compared with the basal diet. In one further study, rats were daily exposed (gavage) to doses equivalent to 0, 500, 2,500 or 5,000 mg/kg bw per day. Animals treated with ≥ 2,500 mg/kg bw per day had soft and pale faeces, which was attributed to the presence of test material and not considered of toxicological relevance. In the absence of any other adverse effects, also for this study, the identified NOAEL was the top dose (5,000 mg/kg bw per day).

  • 4. Personal Care Products HEC is commonly used in personal care products such as shampoos, conditioners, and hair gels due to its conditioning and thickening properties. It also finds application in skin care products, such as moisturizers and sunscreens, for its emollient and protective properties.

  • No analytical data that would support the identification of the active substance and the batch to batch consistency of the additive was provided.

  • In conclusion, China's redispersible powder industry plays a pivotal role in shaping the global construction landscape. Its commitment to innovation, quality, and sustainability positions it as a major player in this sector. As the world continues to seek efficient and environmentally friendly building solutions, China's redispersible powder industry is poised to make a substantial contribution to meeting these needs.

  • Moreover, HPMC finds applications in the paint and coatings industry as a rheology modifier, improving flow properties and preventing sagging during application. It is also used in printing inks for its film-forming properties and in paper manufacturing to enhance the strength and printability of the final product.
