The fomula of hydroxypropyl methylcellulose (HPMC) is-H -CH3 or -CH2CHOHCH3. The production of hydroxypropyl methylcellulose (HPMC) primarily involves three reactions:
1. Alkali treatment of cotton linter
2. Etherification
3. Neutralization
As an HPMC production company, Celix HPMC production process is as follows:
Hydroxypropylmethylcellulose (HPMC) is made from pure cotton. After its trituration, it is alkalinized with
a solution of sodium hydroxide, to which chloromethyl and propylene oxide are added for etherification,
thus obtaining pure HPMC. After neutralization (pH adjustment), pressure filtration, drying, grinding and
sieving, a pure HPMC product with a certain degree of purity is finally obtained.

Celix Cellulose (Hebei Celix Cellulose Co., Ltd.) is a Chinese chemical manufacturer specializing in cellulose ethers and construction additives like HPMC, HEC, HEMC, RDP, used to improve building materials, coatings, and detergents for better workability, adhesion, and water retention. Established in 2007, Celix focus on green, technology-driven solutions, serving both domestic and international markets with products that enhance performance in tile adhesives, mortars, plasters, and more, aiming for high-quality, sustainable materials.
HPMC (Hydroxypropyl Methylcellulose) is widely used a thickener, binder, and stabilizer across various industries, including construction, pharmaceuticals, food and personal care. In construction, it improves workability for tile adhesive, mortar and plaster . In pharmaceuticals, it's a binder, thickener in tablets and coatings.
In construction, it boosts water retention, adhesion, and workability of building materials. In pharmaceuticals, it controls drug release, thickens liquids. It provides stability, film - forming properties in various applications.
As of current knowledge, there's no general ban on HPMC in Brazil. Check Brazil's ANVISA (National Health Surveillance Agency) and relevant import/usage regulations for the latest status.
First, confirm the supplier's qualifications, product quality (certifications like ISO). Arrange shipping, handle customs clearance with proper docs (commercial invoice, packing list, certificate of origin). Comply with China’s export and your country’s import rules.
Second, you'd better get the price from the direct factory, like Celix Cellulose, the 18-year experienced HPMC supplier. They have the enough trade information for you.
Third, get a sample to test it.
Forth, be careful about the package type. You need to choose the 25kg bag for sale with your own logo or the OEM brand .
HPMC is generally recognized as safe. It’s biocompatible and non-toxic.
