Hydroxypropyl Methylcellulose (HPMC) is a widely used ingredient in industries like construction, pharmaceuticals, and food. Different HPMC grades have unique properties, such as viscosity, molecular weight, and degree of substitution (DS).
These differences make certain grades better for specific uses. For example, in construction, HPMC helps improve water retention and workability in cement, plaster, and tile adhesives. In pharmaceuticals, it’s used in tablet coatings and to control how drugs are released.
Knowing the right HPMC grade for a job helps get the best results. This ultimate guide is here to provide you with helpful tips when choosing the right HPMC.
The full form of HPMC is Hydroxypropyl Methylcellulose. It appears as a white powder or fibrous substance. It is non-toxic and odorless. When mixed with cold water, it swells into a clear or slightly cloudy gel.
HPMC is a semi-synthetic polymer made from natural cellulose found in plants. It is modified through a chemical process called etherification. This modification creates different grades of HPMC. These grades vary by molecular weight, substitution degree, and viscosity. This article will mainly focus on the classification of HPMC viscosity.
Generally, HPMC grades are classified by viscosity and can be categorized into low (LV), medium (MV), and high (HV) grades. HPMC viscosity is usually expressed in centipoise (cP) or millipascal seconds (mPa-s). Different HPMC viscosity levels indicate different performance characteristics.
HPMC (Hydroxypropyl Methylcellulose) is available in various viscosity grades, each offering unique properties for different applications and uses.
HPMC powder is commonly used in construction materials such as cement, plaster, lime, mortar, and grout. It has the following properties:
– Improving the consistency of building materials
– Emulsifies construction materials
– Improves the water retention of the slurry
– Improve the stability of building materials

Below are a few common construction-grade HPMCs.
Grades Viscosity Grades Main Applications and Properties HPMC E5 lower In the construction industry, E5 grade HPMC can be used as a thickener and binder for cement mortar, which helps to improve the adhesion and processing performance of mortar. HPMC E15 higher than HPMC E5 It is usually used to prepare high-performance cement mortar, tile adhesive, plaster mortar, etc. to improve its fluidity, crack resistance, and adhesion. HPMC F50 film-forming grade Usually used in coatings, paints, and adhesives. HPMC F high Used in construction materials such as gypsum-based plasters and cement-based products where excellent water retention and viscosity are required.With 10 years of experience in the construction and chemical industries, our company WotaiChem is constantly upgrading its formulations to meet the needs of our customers. We can provide you with the right grade of HPMC for your application. Learn more.
In the pharmaceutical industry, as a drug excipient, HPMC also has a wide viscosity range, which is needed to meet the release needs of drugs with different solubilities, such as:
· Tablet coating
· Tablet Binding
· Controlled release formulations
· Film coating
· Suspensions
· Ophthalmic lubricants, eye drops
The following are some common medical-grade HPMCs.
Grades
Viscosity Grades Main Applications and Properties HPMC K4M HPMC is often used in medicines as a base for slow-release formulations. It helps control the release of the active ingredient over a longer period. Lower HPMC K15M It’s commonly used to bind tablets, create controlled-release drugs, and thicken liquid medicines. Medium HPMC K100M HPMC provides strong thickening and gelling properties, making it useful in slow-release medications and as an adhesive in tablet production. HigherFood grade hydroxypropyl methylcellulose is mainly used as emulsifiers and thickeners, but with no nutritional value.

The molecular weight of the HPMC powder ranges from around 10,000 to 1,500,000. The molecular weight affects its physical properties, like solubility, gel formation, and film-forming ability. It also influences the mechanical strength and viscosity of HPMC solutions.
– High molecular weight HPMC is ideal for applications that need high viscosity and strong water solubility, such as slow-release formulations in pharmaceuticals. It also offers better film-forming properties and greater resistance to enzyme breakdown in other uses.
– Low molecular weight HPMC works well in applications that need lower viscosity and better flow, such as in paints and adhesives.
The degree of substitution (DS) in Hydroxypropyl Methylcellulose (HPMC) refers to how many of the natural groups in the cellulose are replaced by hydroxypropyl or methyl groups. This affects how HPMC behaves in different products.
For example, a higher degree of substitution makes it dissolve better in water and improves its ability to thicken, stabilize, or form films. This is important in industries like construction, food, and pharmaceuticals, where HPMC is used to improve the quality of products.
HPMC is generally classified into three grades: K, E, and F, which represent different degrees of substitution for methoxy and hydroxypropyl groups. For example, HPMC K4M, E4M, and F4M all have the same viscosity of 4,000 centipoise (cP). However, the chemical substitution levels of hydroxypropyl and methoxy groups differ among these types.
These include desired viscosity, film-forming ability, water retention, and ingredient compatibility. It is also important to consider formulation parameters like pH, temperature, and processing conditions.
For example, in hot summer temperatures or warm climates, the moisture in construction mortar evaporates quickly. This requires HPMC to have better water retention. Higher viscosity HPMC provides better water retention. In colder winter temperatures, a lower viscosity HPMC can be used.
Before purchasing HPMC, it is best to consult a qualified formulator or technical expert, such as WotaiChem. Our experts can help you pick the best HPMC grade for your use.

Additionally, HPMC grades used in pharmaceuticals and food applications must meet relevant quality standards and regulations, such as the United States Pharmacopeia (USP) and the European Pharmacopeia (Ph. Eur.). These standards set requirements for purity, chemical composition, and performance characteristics to ensure product safety and effectiveness.
With technological advancements, there is potential for further improvements and innovations in HPMC performance, and its grades may continue to evolve. HPMC grades and formulations can also vary by manufacturer and specific product requirements. Therefore, it is advisable to consult a reputable HPMC manufacturer or supplier, such as WotaiChem, for guidance on HPMC grades and formulations.
