Hydroxypropyl Methyl Cellulose

Hydroxypropyl Methyl Cellulose HPMC

Hydroxypropyl Methyl Cellulose (HPMC), also known as Hypromellose, is a semi-synthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient or controlled-delivery component in oral medicaments. It’s a non-ionic type of cellulose ether, which forms a colloidal solution when hydrated and can produce a very viscous solution with interesting thermal gelling properties.

Here are some key points about HPMC:

1. Appearance: It is typically available as a white powder or granules.

2. Solubility: Soluble in water and some organic solvents, such as ethanol/water mixtures, propylene glycol/water mixtures, and others.

3. Viscosity: The viscosity of HPMC solutions can vary depending on the grade and concentration.

4. Applications: It’s widely used in the food industry as an emulsifier, thickening agent, and suspending agent. In the pharmaceutical industry, it serves as a drug delivery vehicle due to its controlled-release properties.

5. Safety: HPMC is considered safe for use in both food and pharmaceuticals.

Hydroxypropyl Methyl Cellulose is also used in various other industries such as construction, ceramics, paper, leather, and cosmetics for its thickening, emulsifying, and stabilizing properties. If you’re looking for more specific information or a particular application, please let me know!
