Superiority

Hydroxypropyl Methyl Cellulose (HPMC) are water soluble polymers derived from cellulose. They are typically used as thickeners, binders, film formers, and water retention agents. They also function as suspension aids, surfactants, lubricants, protective colloids, and emulsifiers. In addition, solutions of these polymers thermally gel.
hydroxypropyl methyl cellulose has many excellent properties. lt is presented below some examples of HPMC applications:
Food industry: stabilizers of emulsions and foams, as a replacement for fat, as a non-caloric bulking agentin foods, as a binder, among others.
Pharmaceutical industry: as a dispersing and thickening agent, film-coating of tablets, drug preparations,among others.
Cosmetics industry: hair shampoo, eye makeup, skin care preparations, among others.

Hydroxypropyl methyl cellulose is a propylene glycol ether of methylcellulose in which both hydroxypropyl and methyl groups are bound to the anhydrous glucose ring of cellulose by ether linkages. Hydroxypropyl methyl cellulose is synthesized from methyl cellulose by the action of alkali and propylene oxide. The resultant product is a water soluble ether derivative of cellulose containing both methoxy and hydroxypropyl groups. The degree of substitution is 1.08 to 1.83 with the hydroxypropyl groups as the minor constituent. White to off-white fibrous powder or granules. Soluble in water and some organic solvents. Insoluble in ethanol, the aqueous solution has surface activity, forms a thin film after drying, and undergoes a reversible transition from sol to gel in turn by heating and cooling.

Hydroxypropyl Methylcellulose is a gum formed by the reaction of propylene oxide and methyl chloride with alkali cellulose. it will gel as the temperature is increased in heating and upon cooling will liquefy. the gel temperature ranges from 60°c to 90°c, forming semifirm to mushy gels. it is used in bakery goods, dressings, breaded foods, and salad dressing mix for syneresis control, texture, and to provide hot viscosity. usage level ranges from 0.05 to 1.0%.

Hydroxypropyl methyl cellulose is used as an ophthalmic lubricant, an emulsifier and a thickening and suspending agent. It is widely used as an excipient in pharmaceutical formulations. It acts as a food additive. Its eye drops are known as artificial tears, which are used to relieve eye dryness and soreness. It finds applications in various fields as emulsifier, film former, protective colloid, stabilizer, suspending agent, or thickener in foods. Pharmaceutic aid (suspending agent; tablet excipient; demulcent; viscosity increasing agent); hydrophilic carrier in drug delivery systems. In adhesives, asphalt emulsions, caulking compounds, tile mortars, plastic mixes, cements, paints.
