What is the Hydroxypropyl methyl cellulose?

Hydroxypropyl methyl cellulose is white to off-white powder, while it's Molecular Formula is C3H7O*. white to off-white powder 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%.

What is the CAS number for Hydroxypropyl methyl cellulose?

The CAS number of Hydroxypropyl methyl cellulose is 9004-65-3.

What is Hydroxypropyl methyl cellulose (9004-65-3) used for?

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.InChI:InChI=1/C36H70O19.C20H38O11/c1-19(37)9-45-17-27-29(47-11-21(3)39)31(48-12-22(4)40)34(51-15-25(7)43)36(54-27)55-30-28(18-46-10-20(2)38)53-35(52-16-26(8)44)33(50-14-24(6)42)32(30)49-13-23(5)41;1-21-9-11-13(23-3)15(24-4)18(27-7)20(30-11)31-14-12(10-22-2)29-19(28-8)17(26-6)16(14)25-5/h19-44H,9-18H2,1-8H3;11-20H,9-10H2,1-8H3/t19?,20?,21?,22?,23?,24?,25?,26?,27-,28-,29-,30-,31+,32+,33-,34-,35-,36+;11-,12-,13-,14-,15+,16+,17-,18-,19-,20+/m11/s1

Food Additive HPMC 9004-65-3 Usage

Hydroxypropyl methylcellulose belongs to the group of medicines known as artificial tears. Hydroxypropyl methylcellulose (HPMC) is a cellulose ether widely used in drug formulations due to its biocompatibility, uncharged nature, solubility in water and thermoplastic behavior. Particularly for ocular and ophthalmic formulations, HPMC is applied as viscosity enhancer agent in eye drops, gelling agent in injections, and polymeric matrix in films, filaments and inserts. In recent years, It has been widely used in petroleum chemical industry, papermaking, leather, textile printing and dyeing, pharmaceutical, food, cosmetics and other industries, and as the dispersing agent, thickening agent, adhesive, excipient, capsule, oil resistant coating and packing etc.
