What is HPMC K15M?
What is HPMC K15M?
METHOCEL™ K15M is an HPMC polymer with moderate hydroxypropyl substitution. It is typically used as a thickener, binder, or suspension aid in coatings, adhesives, or cleaners where a thixotropic rheology is desired. METHOCEL™ K15M is also used to control the viscosity of latex architectural paints and coatings.
Is HPMC a cellulose?
Hydroxypropyl methyl cellulose (HPMC; CAS No. 9004-65-3) is an odorless and tasteless, white to slightly off-white, fibrous or granular, free-flowing powder that is a synthetic modification of the natural polymer, cellulose. It is used in the food industry as a multipurpose food ingredient.
What is hydroxypropyl methylcellulose good for?
Hydroxypropyl methylcellulose belongs to the group of medicines known as artificial tears. It is used to relieve dryness and irritation caused by reduced tear flow. It helps prevent damage to the eye in certain eye diseases.
What is HPMC coating?
As a binder, HPMC is used at the concentration of 2%–5% w/w, however, it has been commonly used as tablet film coating polymer. The polymer chain length, size and degree of branching determine the viscosity of the polymer in solution. In general, a tablet film coating requires low viscosity polymers.
What is HPMC E15?
METHOCEL™ E15 Premium LV is a low molecular weight hydroxypropyl methylcellulose (HPMC) thickener. It yields a viscosity of ~15 cP at 2% in water.
What is K in HPMC k4m?
K means gelling temperature is between 70-90℃. The viscosity is 4000cps.
Is HPMC harmful?
It is now an EU and FDA-approved food additive and is considered non-toxic to humans.
Is HPMC a synthetic polymer?
(1)HPMC or Hydroxypropyl methylcellulose (INN name: Hypromellose), also simplified as hydroxypropyl methylcellulose (HPMC), is a kind of non-ionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer.
How safe is hydroxypropyl methylcellulose?
What are the side effects of hydroxypropyl methylcellulose?

- continued eye redness or irritation.
What is the difference between CMC and HPMC?
Results: In comparison with HPMC, CMC effected less corneal staining, greater comfort, and better vision after the procedure, Conclusion: CMC proved to be a viable and superior alternative to HPMC as a gonioscopic solution.
Is HPMC biodegradable?
HPMC is hydrophilic (water soluble), a biodegradable, and biocompatible polymer having a wide range of applications in drug delivery, dyes and paints, cosmetics, adhesives, coatings, agriculture, and textiles [174–176]. HPMC forms flexible and transparent films from aqueous solution.
