Chemical PropertiesHydroxypropyl methyl cellulose is propylene glycol ether of methyl cellulose, hydroxypropyl and methyl combine with anhydrous glucose ring by ether bond.It is white or pale white cellulose powder or particles.It has different types of products, the methoxy and hydroxypropyl content ratio is different. It is white or gray fibrous powder or particles. It is soluble in water and some organic solvents and unsoluble in ethanol. Aqueous solution has a surface activity, the formation of the film after drying, heated and cooled, in turn, from the sol to gel reversible transformation.
ApplicationsHydroxypropyl 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.
DescriptionCellulose is a natural substance normally present in most diets because it is the major structural carbohydrate of green plants. Cellulose is essentially a linear polymer of glucopyranose units connected by (3-1,4-glucoside links. In nature, cellulose is present in plant cell walls as fibers. The molecular weight of isolated cellulose is approximately 50,000. The principal sources of cellulose for food related purposes are cotton linters and wood pulp. Chemical processing converts cellulose into forms or derivatives suitable for incorporation into food products, or for use in food packaging materials. Hydroxypropylmethyl 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. It is used as a thickening agent, stabilizer, and emulsifier.
Chemical Propertieswhite or slightly beige powder or a viscous solution
Chemical PropertiesHypromellose is an odorless and tasteless, white or creamy-white fibrous or granular powder.
UsesHypromellose is a thickener for aqueous and non-aqueous systems, clear films with grease resistance, binders, lubricants, steric stabilizer and water retention aid. As a food additive, hypromellose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin.
UsesAs 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.
UsesHydroxypropyl 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%.
