Propylene Glycol (PG) / Propilenglicol 99.5%, 99.9% CAS No.:
57-55-6 Product DescriptionPropylene glycol is scientifically
named as "1,2-propanediol", and has a chemical formula of
CH3CHOHCH2OH and a molecular weight of 76.10. There is a chiral
carbon atom in the molecule. Its racemate is a hygroscopic viscous
liquid and is slightly spicy. It has a specific gravity of 1.036
(25/4 °C), a freezing point of-59 °C, and a boiling point of 188.2
°C, respectively 83.2 °C (1,333 Pa). It is miscible with water,
acetone, ethyl acetate and chloroform, and is soluble in ether. It
is soluble in many essential oils, but is not miscible with
petroleum ether and paraffin oil. It is relatively stable to heat
and light, and is more stable at low temperatures. Its L-isomer has
a boiling point of 187 to 189 °C and a specific optical rotation
[α] of D20-15.0°. It can be oxidized at high temperatures to
propionaldehyde, lactic acid, pyruvic acid and acetic acid. It
is produced on a large scale primarily for the production of
polymers. In the European Union, it has E-number E1520 for food
applications. For cosmetics and pharmacology, the number is E490.
Propylene glycol is also present in propylene glycol alginate,
which is known as E405. Propylene glycol is a compound which is
GRAS (generally recognized as safe) by the US Food and Drug
Administration under 21 CFR x184.1666, and is also approved by the
FDA for certain uses as an indirect food additive. Propylene glycol
is approved and used as a vehicle for topical, oral, and some
intravenous pharmaceutical preparations in the U.S. and in
Europe.Product Features:The content of industrial propylene glycol
is over 99.5%, and the product has a stable quality and high
operating rate. It can meet various demands of customers and has
won unanimous praise from customers.Packaging and Transportation:·
It can be packaged in a galvanized iron bucket or a plastic drum,
with specifications of 25 kg, 200 kg and 215 kg.· It can be
packaged in an ISO tank or a liquid bag, or according to the
requirements of customers. Detailed Photos
