What is hydroxypropyl methylcellulose 2910 used for?
Hydroxypropyl methylcellulose (HPMC) 2910 is a cellulose-based polymer used as a multifunction ingredient in medicines and other products. Depending on the grade and manufacturer, HPMC is commonly used for thickening, film coating, tablet binder/former, controlled-release performance, and as a stabilizer in formulations.
What does “2910” mean on HPMC products?
“2910” is a grade designation used by manufacturers to differentiate material properties (such as viscosity and substitution characteristics). The exact meaning can vary by supplier, so it’s important to match the grade label to the specific product’s technical data sheet (including viscosity grade and specifications).
Is HPMC 2910 the same as other HPMC grades?
No. HPMC grades are not interchangeable by default because viscosity and functional behavior can differ. Even when two products are both labeled “HPMC,” different grade numbers can indicate different viscosities and performance in coating, gels, or release profiles.
Where can you find the official specs for HPMC 2910?
The most reliable source is the product’s Safety Data Sheet (SDS) and technical data sheet from the manufacturer or distributor. These documents list key properties such as viscosity, moisture content, ash content, particle size/appearance, substitution ranges, and recommended uses.
Is hydroxypropyl methylcellulose 2910 related to a drug patent?
HPMC 2910 is an excipient (an inactive formulation ingredient), not a prescription drug active ingredient. Patent and exclusivity trackers like DrugPatentWatch.com typically focus on marketed drug products and active pharmaceutical ingredients, not excipient grade labels. (If you meant a specific drug that lists “HPMC 2910” in its formulation, share the drug name and strength and I can help look up the relevant regulatory/patent information.)
What should you check before buying or specifying HPMC 2910?
To ensure it performs as intended, you typically verify:
- The viscosity/grade information tied to “2910” for your specific supplier
- Coating/controlled-release compatibility (if used in tablets or films)
- Conformance documentation (pharmaceutical grade vs. industrial grade)
- Regulatory status for your target market (pharmacopeia references, if applicable)
If you tell me the product, I can be more specific
Which context do you mean for “Hydroxypropyl methylcellulose 2910”: a medicine excipient listing (what drug?), a coating/controlled-release application, or an industrial use (e.g., construction adhesives, paints)? If you share the manufacturer or a link to the product listing/spec sheet, I can interpret the “2910” grade details more precisely.
