Polypropylene glycol P-1000 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.
PPG P-1000, as this product is also known, is a clear, viscous liquid at room temperature.

Polypropylene glycol 1000 has a low pour point and, unlike the higher molecular weight PPGs, is completely soluble in water at 25 °C. 
Polypropylene glycol 1000 loses Polypropylene glycol 1000 water solubility at higher temperatures.
Like all polypropylene glycols, Polypropylene glycol P-1000 is soluble in all proportions with any organic solids and liquids, the main exception being long chain aliphatic hydrocarbons.

Polypropylene glycol P-1000 possesses excellent lubricity and has a low vapour pressure. 
Under extreme heating conditions Polypropylene glycol 1000 does not form coke nor does Polypropylene glycol 1000 form a varnish. 
Decomposition products are low boiling products that are either lost as volatiles or soluble in the polypropylene glycol. 

Polypropylene glycol 1000 has many properties in common with polyethylene glycol. 
The polymer is a liquid at room temperature. 
Solubility in water decreases rapidly with increasing molar mass.

What happens when polypropylene glycol 1000 is released into the environment?
Waste streams from the manufacture of Polypropylene glycol 1000 are primarily responsible for the releases into the air, water, and soil. 
Polypropylene glycol 1000 can enter the environment when Polypropylene glycol 1000 is used as a runway and aircraft de-icing agent. 
Polypropylene glycol 1000 can also enter the environment through the disposal of products that contains Polypropylene glycol 1000. 

Polypropylene glycol 1000 is not likely to exist in large amounts in the air. 
We have little information about what happens to Polypropylene glycol 1000 in the air. 
The small amounts that may enter the air are likely to break down quickly. 
If Polypropylene glycol 1000 escapes into the air, Polypropylene glycol 1000 will take between 24 and 50 hours for half the amount released to break down. 

Polypropylene glycol 1000 can mix completely with water and can soak into soil. 
Polypropylene glycol 1000 can break down relatively quickly (within several days to a week) in surface water and in soil. 
Polypropylene glycol 1000 can also travel from certain types of food packages into the food in the package.

Exposure to polypropylene glycol 1000:
Polypropylene glycol 1000 has been approved for use at certain levels in food, cosmetics, and pharmaceutical products. 
If you eat food products, use cosmetics, or take medicines that contain Polypropylene glycol 1000, you will be exposed to Polypropylene glycol 1000, but these amounts are not generally considered harmful. 
People who work in industries that use Polypropylene glycol 1000 may be exposed by touching these products or inhaling mists from spraying them. 

These exposures tend to be at low levels, however. 
Polypropylene glycol 1000 is used to make artificial smoke and mists for fire safety training, theatrical performances, and rock concerts. 
These artificial smoke products may also be used by private citizens. 
These products are frequently used in enclosed spaces, where exposure may be more intense.

Applications of Polypropylene glycol 1000:
As PPG P-1000 is water-soluble Polypropylene glycol 1000 is used in areas not usually associated with the higher molecular weight PPGs. 
For example Polypropylene glycol 1000 is used as a dust adhesive fluid, as solvent/coupler for inks and pesticide formulations. 
Besides the other outlets given above PPG P-1000 is also used to make resins, fatty acid esters, lubricants, metal working fluids and as plasticiser. 

Industrially, Polypropylene glycol 1000 is mainly produced from propylene oxide (for food-grade use). 
According to a 2018 source, 2.16 M tonnes are produced annually.
Manufacturers use either non-catalytic high-temperature process at 200 °C (392 °F) to 220 °C (428 °F), or a catalytic method, which proceeds at 150 °C (302 °F) to 180 °C (356 °F) in the presence of ion exchange resin or a small amount of sulfuric acid or alkali.
Final products contain 20% Polypropylene glycol 1000, 1.5% of diPolypropylene glycol 1000, and small amounts of other polyPolypropylene glycol 1000s.

Further purification produces finished industrial grade or USP/JP/EP/BP grade Polypropylene glycol 1000 that is typically 99.5% or greater. 
Use of USP (US Pharmacopoeia) Polypropylene glycol 1000 can reduce the risk of Abbreviated New Drug Application (ANDA) rejection.
Polypropylene glycol 1000 can also be obtained from glycerol, a byproduct from the production of biodiesel.
This starting material is usually reserved for industrial use because of the noticeable odor and taste that accompanies the final product.

Polypropylene glycol 1000 is used to make polyester compounds, absorb extra water and maintain moisture in certain medicines, cosmetics, or food products and as a base for deicing solutions. 
Propylene glycol is used by the chemical, food, and pharmaceutical industries as an antifreeze. 
Polypropylene glycol 1000 is a solvent for food colors and flavors, and in the paint and plastics industries. 
Propylene glycol is also used to create artificial smoke or fog used in fire-fighting training and in theatrical productions.

Structure of Polypropylene glycol 1000:
The compound is sometimes called (alpha) α-Polypropylene glycol 1000 to distinguish Polypropylene glycol 1000 from the isomer propane-1,3-diol, known as (beta) β-Polypropylene glycol 1000. 
Polypropylene glycol 1000 is chiral. 
Commercial processes typically use the racemate. 
The S-isomer is produced by biotechnological routes.

Polymerization of Polypropylene glycol 1000:
Polypropylene glycol 1000 is produced by ring-opening polymerization of propylene oxide. 
The initiator is an alcohol and the catalyst a base, usually potassium hydroxide. 
When the initiator is ethylene glycol or water the polymer is linear. 

With a multifunctional initiator like glycerine, pentaerythritol or sorbitol the polymer branches out.
Conventional polymerization of propylene oxide results in an atactic polymer. 
The isotactic polymer can be produced from optically active propylene oxide, but at a high cost. 
A salen cobalt catalyst was reported in 2005 to provide isotactic polymerization of the prochiral propylene oxide.

Safe Use and Handling of Polypropylene glycol 1000:
Polypropylene glycols are relatively easy to store and handle. 
They 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 Polypropylene glycol 1000 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. 

Exposure to Polypropylene glycol 1000 by oral administration:
The acute oral toxicity of Polypropylene glycol 1000 is very low, and large quantities are required to cause perceptible health effects in humans; in fact, Polypropylene glycol 1000 is three times less toxic than ethanol. 
Polypropylene glycol 1000 is metabolized in the human body into pyruvic acid (a normal part of the glucose-metabolism process, readily converted to energy), acetic acid (handled by ethanol-metabolism), lactic acid (a normal acid generally abundant during digestion), and propionaldehyde (a potentially hazardous substance). 

Toxicity generally occurs at plasma concentrations over 4 g/L, which requires extremely high intake over a relatively short period of time, or when used as a vehicle for drugs or vitamins given intravenously or orally in large bolus doses. 
Polypropylene glycol 1000 would be nearly impossible to reach toxic levels by consuming foods or supplements, which contain at most 1 g/kg of Polypropylene glycol 1000, except for alcoholic beverages in the US which are allowed 5 percent = 50g/kg. 
Cases of Polypropylene glycol 1000 poisoning are usually related to either inappropriate intravenous administration or accidental ingestion of large quantities by children.

The potential for long-term oral toxicity is also low. 
In an NTP continuous breeding study, no effects on fertility were observed in male or female mice that received Polypropylene glycol 1000 in drinking water at doses up to 10,100 mg/kg bw/day. 
No effects on fertility were seen in either the first or second generation of treated mice. 

In a 2-year study, 12 rats were provided with feed containing as much as 5% Polypropylene glycol 1000, and showed no apparent ill effects. 
Because of Polypropylene glycol 1000 low chronic oral toxicity, Polypropylene glycol 1000 was classified by the U. S. Food and Drug Administration as "generally recognized as safe" (GRAS) for use as a direct food additive, including frozen foods such as ice cream and frozen desserts. 
The GRAS designation is specific to Polypropylene glycol 1000 use in food, and does not apply to other uses.

Allergic reaction of Polypropylene glycol 1000:
The incidence of allergic contact dermatitis to propylene glycol may be greater than 2% in patients with eczema or fungal infections, which are very common in countries with lesser sun exposure and lower-than-normal vitamin D balances. 
Therefore, propylene glycol allergy is more common in those countries.

First Aid of Polypropylene glycol 1000:
Eyes: First check the victim for contact lenses and remove if present. 
Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. 
Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. 
Immediately transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. 

Skin: immediately flood affected skin with water while removing and isolating all contaminated clothing. 
Gently wash all affected skin areas thoroughly with soap and water. 
If symptoms such as redness or irritation develop, immediately call a physician and be prepared to transport the victim to a hospital for treatment. 

Inhalation: immediately leave the contaminated area; take deep breaths of fresh air. 
If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.
