Detailed Product Description:
A colorless, odorless, nearly tasteless syrupy liquid.  Hygroscopic.  
Soluble in water, alcohol, acetone and most organic solvents.   Often 
used as a non-toxic replacement for ethylene glycol in coolants and 
automotive antifreezes.  Also used as a solvent for fats, oils, waxes, 
perfumes and colognes, hydraulic fluids, bactericides, and deicing fluids 
for aircraft and runways.
 
Grade/Purity:
This is Electrolytic Grade material with minimum purity of 99.8%.
 
Background:
Propylene glycol contains an asymmetrical carbon atom, so it exists in 
two stereoisomers. The commercial product is a racemic mixture.  Pure 
optical isomers can be obtained by hydration of optically pure propylene 
oxide.  
 
This compound is sometimes called á-propylene glycol to distinguish it 
from the isomer propane-1,3-diol HO-(CH2)3-OH, also called â-propylene 
glycol.
 
Propylene glycol, also called 1,2-propanediol or propane-1,2-diol, is 
an organic compound (a diol or double alcohol).  It is a colorless, nearly 
odorless, clear, viscous liquid with a faintly sweet taste, hygroscopic and 
miscible with water, acetone, and chloroform.
 
Production:
Industrially propylene glycol is produced from propylene oxide.  Different 
manufacturers use either a non-catalytic high-temperature process or a 
catalytic method, which proceeds at a lower temperature in the presence 
of an ion exchange resin or a small amount of sulfuric acid or alkali.
Final products contain 20% 1,2-propanediol, 1.5% of dipropylene glycol and 
small amounts of other polypropylene glycols.  Propylene glycol can also be 
converted from glycerol, a biodiesel byproduct
 
Precautions:
Combustible.  May cause slight skin irritation with chronic exposure.
Relatively non-toxic substitute for ethylene glycol.
