- For a long time, the only material used to make capsule shells was gelatine. Gelatine is obtained from the skin and bones of various animal species, especially pigs and cattle. Due to strict regulations on the use of gelatine caused by emerging diseases such as TSE (Transmissible Spongiform Encephalopathy), which includes BSE (Bovine Spongiform Encephalopathy), the search for a substitute for gelatine was encouraged.
Plant-based capsules have also been available on the market since 1998. With HPMC, consumers have a completely safe, plant-based product at their disposal, so that vegans or vegetarians and people who abstain from gelatine due to their religion also have an alternative to gelatine capsules.
HPMC capsules can withstand high temperatures and high humidity and have a low inherent moisture content. This makes the capsule shells suitable for storing moisture-sensitive ingredients. They therefore protect their contents from all kinds of fluctuations, such as temperature fluctuations and humidity. HPMC capsules can therefore be stored well in all climate zones. In contrast, gelatine capsule shells have a lower water content. They therefore quickly become brittle at low humidity.
Despite the many advantages of HPMC capsules, gelatine capsules are still the most commonly used type of capsule in the pharmaceutical industry. One reason for this is probably the lower price. - In the pharmaceutical sector, HPMC serves as an excipient in drug formulations. As a tablet binder, it helps in the compression process, ensuring the uniform distribution of active ingredients. Additionally, it acts as a coating agent, providing a protective layer for enteric coatings and controlled-release formulations. Its suitability for oral, topical, and ocular preparations further underscores its significance in this field.
- In the paint and coating industry, HPMC is used as a binder, which improves the flow and leveling properties of the paint, reduces brush marks, and enhances the overall finish. It also aids in the water resistance and durability of the coating.
No analytical data that would support the identification of the active substance and the batch to batch consistency of the additive was provided.
Why do we use HPMC capsules?
Answer: HPMC serves three functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any chemical reactions. The reasons for bubble formation are as follows:
- The Role of HPMCP in Gelation Temperature
- The versatility of redispersible polymer powders extends beyond their applications in construction and adhesives
- 2. Expanding Application in Food Industry HPMC is also used as a thickener, emulsifier, and stabilizer in the food industry. The increasing demand for processed foods and the rising consumer awareness of healthy eating habits are expected to drive the demand for HPMC in the food industry.
- In conclusion, the price of HPMC is influenced by a complex interplay of various factors, including raw material costs, production processes, demand, geographical location, and government regulations. Understanding these factors is essential for businesses that rely on HPMC for their operations, as it allows them to make informed decisions about purchasing and using this versatile polymer.
- In conclusion, HEC is a versatile and valuable polymer that offers a range of benefits in industrial and pharmaceutical applications. Its unique properties, such as thickening, film-forming, and stabilizing, make it an essential ingredient in a wide variety of products. With its biocompatibility and environmental friendliness, HEC is a reliable choice for manufacturers seeking high-performance materials that are safe for both consumers and the planet.
2. The viscosity of Hydroxypropyl Methylcellulose is related to the size of the molecular weight, and the larger the molecular weight is , the higher the viscosity is. The temperature will also affect its viscosity. As the temperature increases, the viscosity decreases. However, the viscosity of Hydroxypropyl Methylcellulose is less affected by the temperature than Methyl Cellulose, and its solution is stable in storage at room temperature.
- The cello, with its deep and resonant sound, is a captivating instrument that has the ability to touch the hearts of listeners. One important aspect of playing the cello is the size of the instrument, known as cello size.
- Hydroxyethyl cellulose, also known as HEC, is a versatile and important chemical compound used in a wide range of industries. It is a non-ionic, water-soluble polymer derived from cellulose, which is a natural polymer found in plants. HEC is commonly used as a thickening agent, stabilizer, and film-former in various products such as paints, adhesives, cosmetics, and pharmaceuticals.
- In the cosmetics industry, HEC is a popular choice for its non-toxic and non-irritating nature
hydroxyethyl cellulose thickener. It thickens and stabilizes skincare products, such as lotions and shampoos, giving them a desired creamy texture. It also enhances the feel of these products on the skin, providing a luxurious, silky finish.
Hydroxypropyl methyl cellulose (E 464) is currently authorised as a feed additive for all animal species, without a minimum and a maximum content. It is also authorised, quantum satis, for use as a food additive.
- These manufacturers, along with numerous others, contribute significantly to the global hydroxyethyl cellulose market, which has been witnessing steady growth over the years. Factors driving this growth include the rising demand for HEC in the construction industry, particularly in the production of tile adhesives and cementitious materials, as well as its use in the pharmaceutical sector for tablet formulations.
- Gelation Temperature
HPMC
- Furthermore, HPMC is used in the production of controlled-release formulations. By incorporating the polymer into drug delivery systems, the release rate of the active ingredient can be precisely controlled, allowing for targeted therapy and improved patient compliance.
- It is important to note that while a higher HPMC percentage may increase viscosity, it can also affect other properties like solubility and clarity. Therefore, careful selection of the right HPMC grade and its concentration is crucial to achieve the optimal balance between viscosity and other desired attributes.
- HPMC is synthesized through an alkali treatment of cellulose followed by etherification with propylene oxide and methyl chloride. The resulting product is a water-soluble, non-toxic, and odorless powder that exhibits unique properties such as thickening, film-forming, emulsifying, and stabilizing abilities. These characteristics make it a valuable additive in various formulations.
- One notable application of MHEC is in the formulation of tablets for the pharmaceutical industry
china mhec-methhyl hydroxyethyl cellulose manufacturer. It serves as a binding agent, ensuring tablets remain intact during consumption yet disintegrate readily to release the active ingredients. In the food industry, MHEC functions as a texture modifier, enhancing the mouthfeel of various products, including ice cream and sauces. Cosmetic formulations also benefit from MHEC's emulsifying capabilities, which help blend oil and water-based components seamlessly.
- 3. Prepare the Water It is important to use clean, pure water when dissolving HPMC. Tap water may contain impurities that can interfere with the dissolution process. You can use distilled water or bottled water instead. Additionally, make sure the water temperature is between 50°C and 80°C, as this will help the HPMC dissolve faster.
- In the food sector, HPMC is employed as a stabilizer and thickener. The desired viscosity level depends on the specific application, whether it's enhancing the texture of sauces, jams, or creating a smooth, creamy consistency in dairy alternatives.

Low-viscosity hydroxypropyl methylcellulose is mainly used for self-leveling mortar. Its viscosity is low, although its water retention is poor. HPMC 's leveling property is good, and the mortar is dense. Medium and low-viscosity HPMC is mainly used in tile adhesives, joint fillers, anti-cracking mortars, and thermal insulation mortars. It has good constructability, a good water retention effect, and high mortar density. HPMC exists as a water-retaining agent in mortar. Its water-retaining properties prevent the paste from drying too quickly. And cracking after reapplying.
