Polyglycol P-1000E is a linear polymer produced by controlled, catalysed reaction between propylene oxide and water.
The letter P and the number 1000 indicate that the polymer is propylene oxide based and that the approximate average molecular weight is 1000.
Polyglycol P-1000E is a clear, viscous liquid at room temperature.
CAS Number: 025322-69-4
INCI / CTFA nomenclature: PPG-17
Polyglycol P-1000E has a low pour point and, unlike the higher molecular weight PPGs, is completely soluble in water at 25 °C.
Polyglycol P-1000E loses its water solubility at higher temperatures.
Like all polypropylene glycols, Polyglycol P-1000E is soluble in all proportions with any organic solids and liquids, the main exception being long chain aliphatic hydrocarbons.
Polyglycol P-1000E possesses excellent lubricity and has a low vapour pressure.
Under extreme heating conditions Polyglycol P-1000E does not form coke nor does it form a varnish.
Decomposition products are low boiling products that are either lost as volatiles or soluble in the polypropylene glycol.
A liquid polyalkylene glycol used as an antifoam agent in a wide variety of industries, including latex formulations, paper and pulp processing, emulsion paints, and food production.
Uses of Polyglycol P-1000E:
Fiber and textile processing
Food and fermentation
Kosher applications
Paper processing
Personal care
Plastics
Water and wastewater treatment
Chemical intermediates
Foam control
Heat transfer fluids
Industrial surfactants
Synthetic lubricants
Applications of Polyglycol P-1000E:
As Polyglycol P-1000E is water-soluble it is used in areas not usually associated with the higher molecular weight PPGs.
For example Polyglycol P-1000E is used as a dust adhesive fluid, as solvent/coupler for inks and pesticide formulations.
Besides the other outlets given above Polyglycol P-1000E is also used to make resins, fatty acid esters, lubricants, metal working fluids and as plasticiser.
Benefits of Polyglycol P-1000E:
Low pour points
Wide range of hydrophile-lipophile balances and molecular weights
Expand formulating possibilities
Excellent lubricity and solvency

Safe Use and Handling of Polyglycol P-1000E:
Polyglycol P-1000E is relatively easy to store and handle.
Polyglycol P-1000E can be stored in bulk in steel tanks, which should be padded with nitrogen or any other inert gas to prevent air from entering the tank.
If slight iron pickup and colour changes cannot be tolerated then the storage tanks should be constructed from stainless steel.
To ease the handling of polypropylene glycols somewhat, higher storage temperatures should be considered to keep the viscosity of the polyglycols within limits suitable for the pumping equipment available.
The maximum storage temperature should not exceed 40°C to avoid the risk of product degradation.
Pipelines may also require insulation and/or tracing to maintain suitable product temperatures.
Although PPGs have very low pour points, especially polyglycols P-2000E and P-4000E become very viscous at low temperatures.
Consequently it is recommend that they be stored in tanks which are well insulated and heated.
Externally located heating devices are preferable to internally sited ones.
With external heating the risk of accelerating product deterioration is greatly reduced.
Similarly drums should be stored under cover, or preferably inside a warehouse, to maintain the temperature of the polyglycol at a level which allows for easy discharge.
The shelf life of properly stored bulk and unopened drums is, at least, 24 months.

Toxicological Information of Polyglycol P-1000E:
Polyglycols P-2000E and P-4000E are considered to be low in acute oral toxicity, whereas polyglycols P-400E, P-600E, P-1000E and P-1200E are considered to be low to moderate in acute oral toxicity.
They cause no significant skin irritation or sensitisation and are not reportedly absorbed in any appreciable amount.
Direct contact with the eyes may cause slight temporary irritation, similar in character to that caused by mild soap.
Consequently it is recommended that eye protection should be employed and viewed as the minimum level of safety equipment required when working with polypropylene glycols.
