HMC；Hydroxy methyl cellulose
Item No.： I0013
Store at： RT
Grade：AR
Viscosity：≥100000 mpa.s
PH：6.0～7.0
Loss on drying：≤10%
Methoxy content：25～32%
Gel temperature：70°C
Solubility: soluble in water and some organic solvents, such as appropriate proportion of ethanol / water, propanol / water, dichloroethane, etc.Aqueous solution has surface activity, high transparency and stable performance. The solubility changes with viscosity. The lower the viscosity, the greater the solubility.
Thermo gel properties: the gel temperature of different specifications of products is different, HMC decreases with the content of methoxy, the gel point rises, the solubility of water decreases, and the surface activity also decreases.
Dissolution method:
A.Take the required amount of hot water, put it into a container, heat it to above 80 ℃, and gradually add the product under slow stirring. HMC floats on the water at first, but is gradually dispersed to form a uniform slurry, and cool the solution under stirring.
B. or heat 1 / 3 or 2 / 3 of hot water to above 85 ℃, add HMC to obtain hot water slurry, then add the remaining amount of cold water, keep stirring and cool the mixture.
Physicochemical properties: white or light yellowish brown, powdery or fine-grained, hygroscopic. It is easy to disperse in hot or cold water.The aqueous solution is stable at pH 2 ~ 10.The pH of 1% solution is 6.5 ~ 8.0.It has the characteristics of thickening ability, salt drainage, low ash, pH stability, water retention, dimensional stability, excellent film-forming, extensive enzyme resistance, dispersion and adhesion.
Purpose: Biochemical research. It can be used as thickener, dispersant, emulsifier and film-forming agent.
