CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Slightly hygroscopic white to off-white, odourless and tasteless powder |
|---|---|
| Color/Form | WHITE NEEDLES FROM BENZENE |
| Melting Point | 240-255 °C |
| Solubility | Practically insoluble in water, in glycerol and in propane-1,2-diol but soluble in varying proportions in certain organic solvents depending upon the ethoxyl content. Ethyl cellulose containing less than 46 to 48 % of ethoxyl groups is freely soluble in tetrahydrofuran, in methyl acetate, in chloroform and in aromatic hydrocarbon ethanol mixtures. Ethyl cellulose containing 46 to 48 % or more of ethoxyl groups is freely soluble in ethanol, in methanol, in toluene, in chloroform and in ethyl acetate |

| LogP | 5.50 |
| Stability/Shelf Life | Very stable chemically /Cellulose ethers/ |
| Optical Rotation | SPECIFIC OPTICAL ROTATION: +26.1 DEG @ 20 °C/D (IN BENZENE) |
| pH | Neutral to litmus (1 % colloidal solution) |
| Refractive Index | Index of refraction: 1.47 |
| Other Experimental Properties | MEDIUM-TYPE VISCOSITY GRADE CONTAINS LESS THAN 46.5% ETHOXY GROUPS; STANDARD-TYPE VISCOSITY GRADE CONTAINS 46.5% OR MORE |
| Chemical Classes | Other Classes -> Other Organic Compounds |
