What is hydroxypropyl methylcellulose used for?

Hydroxypropyl Methylcellulose is used in the construction, laundry, pharmaceutical, and food industries. Construction industry: HPMC is used as a binder for mortar, cement and gypsum-based materials. It can improve the fluidity of mortar, prolong the open time and enhance the bond strength. It prevents tiles from falling off when they are laid. Laundry industry: HPMC is used as a thickener for laundry detergent and softener to produce better fluidity and stability. Pharmaceutical industry: HPMC is used as an excipient for tablets and capsules to control drug release, increase adhesion when pressing tablets, and even improve taste. It is also used as a thickener in liquid preparations such as eye drops. Food industry: HPMC is used as a food additive, acting as an emulsifier and thickener in baked goods, which can improve the overall taste of the food.

Is hypromellose and hydroxypropyl methylcellulose same?

Hypromellose and Hydroxypropyl Methylcellulose refer to the same compound. The different names can be used interchangeably and the essence is the same. Also, the CAS number for hydroxypropyl methylcellulose is 9004-65-3, ChemSpider is 21241863, and the E number is E464. Anyone hearing these designations can be understood to mean hydroxypropyl methylcellulose. It is as if a person has multiple passports of the same identity.

Difference between manufacturer and distributor.

When buying HPMC, many customers only like to go to the producer because they feel that the quality of the producer is more stable. Some customers don’t care whether it is a manufacturer or a distributor, as long as the other party can provide stable quality products. What is the difference between a manufacturer and a distributor?

Production Plant (Manufacturer)

They usually have the chemicals, equipment and technology needed to produce HPMC and can control the quality of the product and product performance. Quality manufacturing plants typically focus on research and development and continually improve their products to enhance application and performance. Manufacturers usually supply large quantities to distributors or recruit agents in different locations. For example, Kemox is one of the top 5 HPMC manufacturers in China.

Resellers (distributors)

Distributors are companies that buy HPMC products produced by manufacturing plants and sell them to end users. Resellers do not manufacture HPMC, but focus on sales. Some distributors may sell multiple brands of HPMC to meet the needs of their customers. Distributors are usually only responsible for marketing and customer management, and if the distributor has a high turnover or has been working with the manufacturing plant for a long time, the manufacturing plant may also modify the supply to meet the distributor’s needs individually.

Hydroxypropyl methyl cellulose (

HPMC

) is an odorless, tasteless, non-toxic white powder. After being fully dissolved in water, hydroxypropyl methyl cellulose will form a transparent viscous colloid.

Comparison of the advantages and disadvantages of

HPMC

：

1.

• The pure hydroxypropyl methyl cellulose HPMC has a loose visual condition and a small bulk density. The scale is 0.3-0.4/ml.
• The adulterated HPMC has very good fluidity and feels heavier, which is significantly different from the genuine appearance.

• The pure hydroxypropyl methyl cellulose HPMC aqueous solution is clear, the light transmittance is high, and the water retention rate is >97%.
• The adulterated HPMC aqueous solution is relatively dirty, and the water retention rate is difficult to reach 80%.

3.

• Pure hydroxypropyl methylcellulose HPMC should not smell ammonia, starch and alcohol.
• The adulterated HPMC can usually smell all kinds of smells.

4.

• Pure hydroxypropyl methylcellulose HPMC powder is fibrous under a microscope or magnifying glass.
• The adulterated HPMC can observe granular solids or crystals under a microscope or magnifying glass.

Identify the pros and cons of

HPMC

from 4 aspects.

1.Whiteness

Although the whiteness cannot determine whether HPMC is easy to use, and if a brightener is added in the production process, it will affect its quality. However, most of the good products have good whiteness.

2.Fineness

The fineness of HPMC is generally 80 mesh and 100 mesh. The finer the fineness, the better in general.

3.Transmittance

Put hydroxypropyl methyl cellulose (HPMC) in water to form a transparent colloid, and look at its transmittance. The greater the transmittance, the better, indicating that there are fewer insolubles inside. The permeability of vertical reactors is generally good, while that of horizontal reactors is worse.

4.Proportion

The larger the proportion, the better. The high specific gravity is generally due to the high hydroxypropyl content in it, and the higher the hydroxypropyl content, the better the water retention.
