Polyglycerine Usage And Synthesis

Chemical Properties

Viscous liquids to solids. Soluble in water, alcohol, and other polar solvents. Act as humectants much like glycerol but have progressively higher molecular weight and boiling point. Combustible.

Definition

One of several mixtures of ethers of glycerol with itself, ranging from diglycerol to triacontaglycerol. Some examples are (1) diglycerol, possibly (CH2OHCH2OCH2)2, mw 166, a liquid with four –OH groups, viscosity of 287 cs at65.5C; (2) hexaglycerol, mw 4
