HPMC forms flexible and transparent films from aqueous solution
What is Hydroxypropyl methyl cellulose?
Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether obtained by cellulose alkalization, etherification, neutralization, and washing. HPMC has good thickening, dispersing, emulsifying, and film-forming. Hydroxypropyl methylcellulose (HPMC) is a derivative of methylcellulose. HPMC is a non-ionic cellulose ether made from natural renewable polymers like cotton or wood pulp. It is an odorless, tasteless, non-toxic white powder that can form a transparent viscous solution when dissolved in cold water. Hydroxypropyl methylcellulose (HPMC) belongs to the group of cellulose ethers in which hydroxyl groups have been substituted with one or more of the three hydroxyl groups present in the cellulose ring. 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.
HPMC is also soluble in polar organic solvents
HPMC is also soluble in polar organic solvents, making it possible to use both aqueous and nonaqueous solvents. It has unique solubility properties in both hot and cold organic solvents. HPMC possesses increased organo-solubility and thermo-plasticity compared to other methylcellulose counterparts. It forms a gel upon heating with a gelation temperature of 75–90oC. By reducing the molar substitution of the hydroxyl propyl group, the glass transition temperature of HPMC can be reduced to 40oC.
HPMC forms flexible and transparent films from aqueous solution.
HPMC forms flexible and transparent films from an aqueous solution. HPMC films are generally odorless and tasteless and can effectively reduce the absorption of oil from fried products such as French fries because of their resistance to oil migration. It is extensively used in the food industry as a stabilizer, as an emulsifier, as a protective colloid, and as a thickener. HPMC is a raw material for coatings with moderate strength, moisture and oxygen barrier properties, elasticity, transparency, and resistance to oil and fat. It is also used as a tablet binder and matrix for extended release. The potential application of HPMC in the biomedical field has attracted great attention from both scientists and academicians because of its excellent biocompatibility and low toxicity.
