- When purchasing, ensure to check the product specifications, such as viscosity, molecular weight, and degree of ethoxylation, as these factors can significantly influence the performance of HEC in your application. Also, don't forget to inquire about certifications (e.g., GMP, ISO) and any relevant safety data sheets (SDS).
- In the construction industry, MHEC is commonly used as a thickener, stabilizer, and water retention agent in cement-based products such as tile adhesives, grouts, and self-leveling compounds. It improves the workability of the mix, reduces water loss, and enhances the adhesion and durability of the final product. Our MHEC is designed to meet the demanding requirements of the construction industry, providing excellent performance and consistency.
- Hydroxypropyl methylcellulose (HPMC) solution is a commonly used material in the pharmaceutical, cosmetic, and construction industries. It is a water-soluble polymer derived from cellulose that has a wide range of applications due to its unique properties.

- In the world of topical formulations, HPMC serves as an exceptional thickener and stabilizer
- In an era where sustainable solutions are not just a preference but a necessity, hydroxyethylcellulose (HEC), a natural derivative from cellulose, emerges as a versatile and eco-friendly ingredient that holds significant promise. Derived from the abundant natural resource of wood pulp or cotton fibers, HEC is a testament to how nature's bounty can be transformed into a powerful tool for various industries.
- HPMC, or Hydroxypropyl Methylcellulose, is a widely used pharmaceutical and industrial compound known for its versatile properties. It's a cellulose derivative that serves as an excipient in various medications, acting as a binder, thickener, or disintegrant. However, like any substance, HPMC can have potential side effects, especially when consumed in large quantities or by individuals with specific sensitivities.
- Furthermore, the demand for HPMC also plays a significant role in determining its price
hpmc price. In times of increased demand, such as during construction booms or when there is a surge in the production of pharmaceuticals, the price of HPMC may rise due to limited supply. Conversely, during periods of decreased demand, prices may fall as suppliers compete to attract customers.
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.
- Further complexity arises from the differentiation of HPMC based on its viscosity grade. The viscosity grade indicates the thickening power of an HPMC solution and is typically measured in centipoise (cP). Low-viscosity grades (10-100 cP) are ideal for wet granulation processes due to their enhanced solubility. Medium-viscosity grades (3000-6500 cP) find use in sustained-release matrices, while high-viscosity grades (over 10,000 cP) are employed for thickening and stabilizing suspensions Medium-viscosity grades (3000-6500 cP) find use in sustained-release matrices, while high-viscosity grades (over 10,000 cP) are employed for thickening and stabilizing suspensions

- In conclusion, redispersible polymer powders are not just a simple ingredient; they are a technological breakthrough that has revolutionized the way we approach construction and chemical applications. With ongoing research and development, their role in the industry is poised to expand even further, contributing to more durable, efficient, and environmentally friendly solutions.
- Furthermore, mortar bonding agents can also improve the workability and consistency of the mortar mix
- Hydroxyethyl cellulose (HEC), a semi-synthetic polymer derived from cellulose, is a widely used rheology modifier and thickening agent in various industries, including pharmaceuticals, cosmetics, and construction materials. A key aspect of its application lies in its solubility, which significantly influences its functionality and performance.

hydroxyethyl cellulose for paint. Rheology Modifier HEC can also act as a rheology modifier, controlling the flow and leveling properties of paint. It allows painters to achieve the desired brushstroke and leveling characteristics, resulting in a professional-looking finish.
- Outside of the pharmaceutical industry, HPMC is widely used in the construction industry as a thickening agent in cement and mortar. It helps to improve workability and adhesion, making it easier to apply and reducing the risk of cracking or shrinkage
use of hpmc. HPMC can also be used as a water retention agent in plaster and stucco, helping to improve the consistency and workability of these materials. - 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.
- One of the main uses of hydroxypropyl methyl cellulose is in the construction industry. HPMC is added to construction materials such as cement, mortar, and tile adhesives to improve their water retention, workability, and adhesive properties. It acts as a thickening agent and a protective colloid, preventing the segregation of particles and enhancing the overall performance of the materials. HPMC is also used in gypsum-based products to enhance their stability and durability.
- Temperature also plays a significant role in HPMC's solubility
The ANS Panel considered that the read-across from methyl cellulose and carboxymethyl cellulose to other modified celluloses bearing similar simple substituents (including HPMC) was justified.
Other uses: It acts as a thickening agent, coating polymer, binder, and bioadhesive in pharmaceutical, food, and industrial manufacturing.



Hydroxypropyl methyl cellulose is considered safe for all animal species. Setting a maximum content in complete diets is not considered necessary.
Hydroxypropyl methyl cellulose is authorised to be used as a food additive in accordance with Annex II to Regulation (EC) No (1333/2008)3 with specific purity criteria defined in Commission Regulation (EU) No 231/2012.4



Answer:1) whiteness: although whiteness can not determine whether HPMC is good, and if it is added in the production process of whitener, will affect its quality. However, good products are mostly white.
2) Fineness: HPMC fineness generally has 80 mesh and 100 mesh, 120 purpose is less, the finer the fineness is generally better.
3) transmittance: the hydroxypropyl methyl cellulose (HPMC) into the water, the formation of transparent colloid, see its transmittance, the greater the transmittance, the better, that less insoluble matter inside.
4) Proportion: the larger the proportion is better. It's usually because it's high in hydroxypropyl,
High hydroxypropyl content, water retention is better.
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.
