What is Hydroxypropyl Methylcellulose
Hydroxypropyl Methylcellulose (HPMC) is a semisynthetic, water-soluble polymer derived from cellulose by chemical modification with hydroxypropyl and methyl groups. It is widely used across industries such as pharmaceuticals, food, cosmetics, construction, and personal care due to its versatile properties.
Physical Properties
Appearance: White or off-white powder, odorless and tasteless.
Solubility: Soluble in cold and hot water, forming clear or slightly turbid viscous solutions; insoluble in pure ethanol, ether, acetone, and anhydrous alcohol.
Melting point: 280-300°C
Nutritional Information
Hydroxypropyl Methylcellulose is considered a non-fermentable soluble dietary fiber with minimal to no caloric value. It is not digestible by humans and passes through the digestive system similarly to dietary fiber. Because of this, HPMC provides several health benefits associated with soluble fiber
Hydroxypropyl Methylcellulose Benefits
The benefits of Hydroxypropyl Methylcellulose (HPMC) span multiple industries due to its versatile physical and chemical properties. Key benefits include:
In Construction and Building Materials:
Enhances bonding and lubricity of cement panels and mortars, improving workability, pumpability, and ease of application.
