Botai has recently launched two high-performance pharmaceutical-grade Hydroxypropyl Methylcellulose (HPMC) products—E5 and E3. Leveraging differentiated viscosity properties and versatile functionalities, they provide innovative solutions for pharmaceutical formulations and daily chemical applications.
Core Product Characteristics
-
Botai HPMC E5
-
Medium-High Viscosity: Exhibits excellent suspension capabilities, thickening effects, and emulsifying performance.
-
Key Applications:
-
Serves as a multi-functional excipient, acting as a thickener, dispersant, emulsifier, and film-forming agent.
-
Used in tablet film coating and as an adhesive, significantly enhancing drug dissolution rates and improving tablet water resistance.
-
Combined with synthetic polymer gels in aqueous-alcoholic systems, it prevents syneresis (water separation) from transparent gels and improves water retention.
-
Extends to cosmetics and other daily chemical fields as an efficient thickener and raw material.
-
-
-
Botai HPMC E3
-
Low Viscosity: Possesses thickening, emulsifying, suspending, and gelling properties.
-
Key Applications:
-
Retains the multi-functional excipient properties of E5, with its low viscosity being particularly suitable for:
-
Acting as a pore-forming agent in sustained-release/controlled-release tablets.
-
Serving as a binder and disintegrant for tablets, pills, and granules.
-
-
Also functions effectively as a thickener and stability enhancer in daily chemical applications.
-
-
Industry Value
Both products meet stringent pharmaceutical-grade standards, addressing the dual demands for excipient safety and functionality in the pharmaceutical industry:
-
E5 excels in tablet film coating and high-stability emulsification systems due to its medium-high viscosity.
-
E3‘s low viscosity precisely addresses key challenges in controlled-release formulation processes, particularly for sustained-release applications.
Concurrently, their use in cosmetics and personal care products further expands their market potential in areas like moisturization and texture modification.
Outlook
A spokesperson from Botai Technologies stated: “The synergistic deployment of E3 and E5 covers diverse scenarios—from immediate-release to sustained-release, and from pharmaceuticals to daily chemicals. We will continue optimizing our HPMC product series to provide global clients with higher-performance cellulose ether solutions.”
