Colorless, transparent, odorless, viscous liquid, sweet, with hygroscopicity.
The solubility is miscible with water and ethanol, and the aqueous solution is neutral. Dissolve in 11 times of ethyl acetate, about 500 times of ether. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether, oil.
Main indexes:
| Index | USP 41 | |
| Appearance | Transparent viscous liquid | |
| Purity by wt % | 99.7 min | |
| Specific gravity @ 25 °C | 1.2613 min | |
| Identification A (IR) | Infrared spectrum | |
| Identification B(Limit of Diethylene glycol and ethylene glycol) by wt % | DEG 0.1 max, EG 0.1 max | |
| Identification C (GC) | Pass as Glycerine | |
| Chlorides by ppm | 10 max | |
| Sulphates by ppm | 20 max | |
| Residue on ignition by wt % | 0.01 max | |
| Organic impurities & related compound (individual impurities) by wt % | 0.1 max | |
| Organic impurities & related compound (Total impurities) by wt % | 1.0 max | |
| Chlorinated compound, as Cl by ppm | 30 max | |
| Fatty acid & esters by mL 0.5N NaOH/50g | 1 max | |
| Color APHA | 10 max | |
| Water by wt % | 0.3 max | |
Used as basic organic chemical raw materials, widely used in medicine, food, daily chemical, textile, paper, paint and other industries.
We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
