Formula of Methyl cellulose (MC) : (C7H14O5)n
F.W. of Methyl cellulose (MC) : Nill
CAS no. of Methyl cellulose (MC) : 9004-67-5
DOT of Methyl cellulose (MC) : Nill
NFPA no. of Methyl cellulose (MC) : 1-3-0
Class no.of Methyl cellulose (MC) : Nill
UN no. of Methyl cellulose (MC) : Nill

Physical Properties
a)Appearance:MC is a white or light gray pellet or fibril power with odorless.
b)Solubility:hardly dissolves in waterless ethanol,aether or -acetone,Separate,expands in hot water with temperature about 80oC to 90oC.swiftly dissolves when cool down.The solution is very stable.Gelatin at high temperature.Good humectants with good dispersibility,adhesive,thickener,emulsification,water keep ability and film forming ability and oil resistance.The film formed possesses good toughness,flexibility and transparent.It can dissolve in some organic solvents or some water-organic components.Can be mixed with other emulsification reagent due to non hydronium structure but easy salt out .Solution is stabilized at PH2-12.
c)DENSITY:0.20-0.60g/cm3 with density about 1.3g/cm3.

Dissolving process
MC will agglomerate when directly added to water and then dissolve .In this way it dissolves very slow and hard .Suggested methods as followers:
1.In hot water:
MC does not dissolve in hot water.The primary HPMC can be uniformly disperse in hot water,Then cool down in two ways:
a) Add hot water in container and heated to over 70oC.Add MC gradually while slowly,stir.At the beginning .MC float on the top of water,then turns into slurry state stir and cool down.
b)Add water in container to 1/3 or 2/3 of its content.Heated to over 70oC.Add MC by sequence of a).Make it disperse to form slurry state,Add cool water or ice to the residual content,stir and cool down the mixture.
2..Powder combination.
Mix MC with identical volume of other powder, disperses them sufficiently then add water to the mixture result MC dissolves without agglomeration.
3.organic solvent wet.
Dispersed or wet with organic solvents such as ethanol,glycol or oil,then add water can cause
MC completely dissolves.

Application of Methyl cellulose (MC)

Methyl cellulose (MC) are widely used as thickener,protective glue,auxiliary emulsification reagent,coloring matter,adhesive of tablets or coating forming reagent.Oral defecationreagent as well as bases collutory and eye dropreagent.Main raw materials of Oral defecation reagent and eye drop reagent,Also,it can be used as framework material .MC can be made to hydrophilic sol framework .Micro hole film coating or multi layer coating film It controlled released matrix reagent . MC with low viscosity is usually used as emulsification reagent of water packed oil emulsion while MC with high viscosity can be used as thickener ,adhesive agent suspending reagent and tablets agglutinate .MC can also e mixed with HPMC as film coating of tablets.MC is also widely used in industry line .
MC is used primarily in foods, drugs and cosmetics as a viscosifier, emulsion stabilizer, thickener and to improve texture. The main applications of technical grade are in textile warp sizing and paper processing. CMC is also used in detergent as a antiredeposition agent, textile warp-sizing aid, adhesives, latex paints and polishes.
Methyl cellulose is 35.000 mPas according to Brookfield measurements FOR formulating tile adhesive recipes
