Frequently Asked Questions (FAQ)
What is Hydroxypropyl Methylcellulose (HPMC)?
Hydroxypropyl Methylcellulose (HPMC) is a versatile, semi-synthetic, inert polymer derived from natural cellulose. It is widely used as a thickener, binder, film-former, and water-retention agent across various industries.
How is HPMC used in the construction industry?
In construction, HPMC is an essential additive in dry-mix mortars, tile adhesives, wall putties, and self-leveling compounds. It improves water retention, workability, open time, and sag resistance.
What role does HPMC play in pharmaceuticals?
In the pharmaceutical sector, HPMC is used as a tablet binder, film-coating agent, and in controlled-release drug delivery systems. It is also a key ingredient in ophthalmic lubricants (eye drops) to relieve dry eyes.
Is HPMC safe for use in food and cosmetics?
Yes, HPMC is generally recognized as safe (GRAS) by global regulatory authorities. In food, it acts as a stabilizer, emulsifier, and gluten alternative. In cosmetics, it functions as a thickener and stabilizer in creams, lotions, and shampoos.
Why is HPMC preferred over other cellulose ethers?
HPMC offers superior thermal gelation, stable pH resistance, excellent film-forming properties, and outstanding water retention capacity, making it highly adaptable for complex industrial formulations.
