Hpmc Grade Classification 

When talking about the grading of HPMC (hydroxypropylmethylcellulose), we involve its requirements and standards in different fields of application. HPMC is a water-soluble polymer whose performance and purity requirements vary due to its diverse applications in medicine, food, construction, cosmetics and other fields.

First of all, pharmaceutical grade HPMC is a type of product used in the pharmaceutical field. This type of HPMC usually requires a high degree of purity, does not contain harmful substances, and is non-allergenic to the human body. To ensure compliance with drug preparation standards, pharmaceutical grade HPMC usually needs to follow pharmacopoeia standards, such as the United States Pharmacopeia (USP) or the European Pharmacopoeia (Ph. Eur.).

Secondly, food-grade HPMC is widely used in the food industry. This type of HPMC needs to comply with relevant food regulations and standards to ensure it is safe and edible. Food-grade HPMC is usually certified by the U.S. Food and Drug Administration (FDA) to ensure its safety in food processing.

In the building and construction sector, we have construction grade HPMC. This HPMC focuses on its properties such as rheology, viscosity and water resistance. Architectural-grade HPMC is widely used in architectural coatings, mortars and other building materials to improve the performance and workability of these materials.

In addition, there are cosmetic grade HPMC, which is used in the manufacture of cosmetics. This HPMC needs to meet the safety standards of cosmetics to ensure that it is non-irritating to the skin, while having a certain viscosity and emulsifying properties to meet the requirements of cosmetic manufacturing.

Finally, industrial-grade HPMC is mainly used in some general applications, such as industrial coatings, glues and other fields. Such products may not need to meet pharmaceutical or food grade purity and safety standards, but may still need to meet specific industrial application requirements.

When selecting HPMC, it is important to select the appropriate grade based on specific application needs and industry standards. Each grade has its own unique characteristics to meet the specific requirements for HPMC product performance and safety in different fields.
