Description: A Clear, Colorless or almost colorless, syrupy liquid; odourless very hygroscopic.
Solubility: Miscible with water & with ethanol (95%) slightly soluble in acetone ; practically insoluble in ether and in fixed oils & volatile oils.
Identification A (By IR): IR spectra of the sample solution should be concomitant with the reference spectrum of glycerin (85%).
Identification B (By Chemical test): The blue color should not be diffuse into the lower layer.
Identification C (By Chemical test): Irritant vapours should evolve which blackens filter paper moistened with alkaline potassium mercuri-iodide solution.
Identification D (By Refractive index, 20±0.5°C): 1.470 to 1.475
Appearance of solution: Solution should be colourless.
Acidity or Alkalinity: Not more than 0.2 mL of 0.1 M sodium hydroxide should require to produce a pink colour.
