Is there a shortage of propylene glycol?
At the current time, there does not appear to be a shortage of propylene glycol. According to the United States Energy Information Administration (EIA), in 2020 the total U. S. production of propylene glycol was nearly 13 billion pounds.
This number is only slightly lower than the 13. 5 billion pounds that was produced in 2019, indicating that propylene glycol is still abundant and readily available.
Due to propylene glycol’s many uses, demand is high and prices typically stay stable. The EIA also reported that the average price of propylene glycol in 2020 was $1. 02 per pound, which is identical to the 2019 value.
This relatively unchanged price indicates that the propylene glycol market overall is not facing significant shortages or supply issues.
In addition, the Global Propylene Glycol Market 2020 Research Report is projecting increases in both production and consumption in the upcoming years. This would suggest that the current propylene glycol supply is meeting or exceeding the demand and that future shortages or scarcity of this raw material are not anticipated.
What is better than propylene glycol?
In certain applications, alternatives to propylene glycol may be better. One potential alternative is vegetable glycerin, which is a thicker and sweeter liquid made from various fats and oils. Vegetable glycerin has different properties than propylene glycol, including a slightly higher vapor pressure, higher hydrogen bonding ability, and higher dielectric constant.
It is odorless, colorless, non-toxic, and naturally sweet.
Another option is polyethylene glycol (PEG). This is often used in cosmetics and skincare products, as it is nontoxic and can help to deliver active ingredients. PEG is different from propylene glycol in that it has a higher water solubility, good viscosity, and lower vapor pressure.
A third option is dipropylene glycol (DPG). This is also odorless and colorless, and is used in a variety of pharmaceutical and cosmetic products as a base material. DPG is slightly more volatile than propylene glycol and produces higher vapor pressure.
Ultimately, when selecting a glycol, the best option for a particular application will depend on the properties and the desired end result. All three alternatives to propylene glycol have their own unique benefits and can be used in various applications.
Is propylene a commodity?
Yes, propylene is a commodity. It is a highly versatile petrochemical used to produce a variety of items, including sealants, plastic bottles and films, fibers, adhesives, antifreeze, and solvents, among many others.
It is one of the most widely-produced petrochemicals in the world, with production capacity having doubled since 2000. Propylene is traded in the commodity markets and its price depends largely on the price of oil and gas, which affect the feedstock used to produce it.
Demand for propylene is also driven by the health and growth of the global economy, as the petrochemical is used in the production of several consumer and industrial goods.
What is propylene used for?
Propylene is an extremely versatile compound used in a wide range of industrial applications. It is most commonly used as a plastic resin, either alone or with other substances, to manufacture items such as automotive parts, medical devices, toys, and containers.
Other applications of propylene include its use a synthetic rubber, in adhesives, as a fuel additive, to create insulation materials, and in paint and coatings. The chemical is also employed to manufacture plasticizers, purification agents for other chemicals, and pesticides.
Last, but not least, Propylene is also a food additive in the form of a preservative.
How is propylene made in industry?
Propylene is typically synthesized from hydrocarbon feedstock through a variety of processes. The most common industrial process to produce propylene is the steam cracker. In this process, ethylene and heavier hydrocarbon molecules are broken down by steam (at 400°C to 700°C) in a reactor at atmospheric pressure.
As a result of this reaction, several byproducts, including propylene, are formed, along with other olefins such as ethylene, butene, and isobutene.
Another common process used to produce propylene is catalytic dehydrogenation (also known as catalytic oxidation or catalytic reforming). In this process, a hydrocarbon feedstock is passed over a catalyst at high temperatures of 300°C to 500°C producing products such as ethylene, propylene, and the corresponding oxygenates.
Finally, there are other processes used to produce propylene in certain geographies, such as metathesis and methanol-to-olefins (MTO). In metathesis, alkanes or alkenes are reacted with a catalyst at moderate temperatures (~150°C to 400°C) to produce an even mixture of multiple olefin products, including propylene.
MTO is a process that converts methanol to a mixture of lower molecular weight products, such as ethylene and propylene, by the use of a zeolite catalyst at a temperature of about 300°C – 500°C.
In summary, propylene is typically made in industry through the process of steam cracking, catalytic dehydrogenation, metathesis, or methanol-to-olefins (MTO).
What drives polypropylene pricing?
Polypropylene pricing is driven by a variety of factors, including global supply and demand, political factors, economic conditions, and different chemical feedstock costs. Supply and demand essentially dictate the price paid for polypropylene resins, with higher demand resulting in higher prices.
Political factors, such as tariffs or trade wars, can have a significant impact on the cost of polypropylene. Economic conditions, such as recession, can also decrease demand for polypropylene and lead to lower pricing.
Lastly, different chemical feedstock costs can affect polypropylene pricing. For instance, ethylene is one of the most important feedstock for polypropylene, and ethylene prices can have an effect on polypropylene.
Is propylene toxic to humans?
Yes, propylene can be toxic to humans if inhaled or ingested. It can cause dizziness, nausea, and headaches if it is breathed in at high levels, and ingestion can lead to irritation of the throat, nose, and eyes.

It is also used as a ripening agent in the agricultural industry, as it accelerates the ripening process in fruits and vegetables. It can be used in industrial stone or woodworking to produce the desired shape or texture in materials.
Ethylene is also used as a gaseous sterilant, as it is known to be effective in killing most microorganisms such as bacteria and fungi.
What is the difference between ethylene and propylene?
The difference between ethylene and propylene is that ethylene is a colorless and flammable hydrocarbon with the chemical formula of C2H4, whereas propylene is a colorless and flammable hydrocarbon with the chemical formula of C3H6.
Ethylene is a two-carbon molecule belonging to the alkene family of hydrocarbons, while propylene is a three-carbon molecule belonging to the same family.
At room temperature, ethylene exists in the gaseous state, and has a boiling point of -103°C. Propylene, on the other hand, has a boiling point of -47°C and is typically found in a liquid state at room temperature.
Ethylene is used for a variety of industrial purposes such as in the manufacture of polyethylene and ethanol. Propylene is widely used as a feedstock in the production of polypropylene, propylene glycol, acrylic acid, and acrylonitrile.
It is also widely used as a chemical intermediate in the manufacture of a number of chemicals.
Is ethylene propylene toxic?
No, ethylene propylene is not considered to be toxic. Ethylene and propylene are both products of oil and natural gas refinement. They are generally considered to be quite safe. Both are used extensively in many industrial and consumer goods, and neither is considered to be a health hazard.
Ethylene propylene is used as a rubber polymer in many applications, such as hoses, belts, and gaskets, as well as a range of other industrial and consumer products. In addition, ethylene propylene can be found in high-performance tires, sealants, insulation, cable jackets, and other applications.
Ethylene propylene is not considered to be hazardous to humans, animals, or the environment. However, it should still be handled and stored properly because it can ignite or be subject to chemical reaction when heated or exposed to certain chemicals.
Is propylene naturally occurring?
No, propylene is not a naturally occurring substance and is instead a hydrocarbon that is derived from petroleum or natural gas. It is created through a process of ethylene cracking, where ethylene (the first result of the process) is exposed to high temperatures and pressure.
This process breaks down the ethylene molecules and creates a number of other compounds including propane, butane, and propylene. Propylene is then further refined to obtain its finished form.
Is propylene petroleum based?
Yes, propylene is petroleum based. Propylene, also known as propene, is an organic compound produced from petroleum-based feedstock. It is one of the most important petrochemical compounds and is used to produce a variety of goods, such as plastics, detergents, synthetic rubbers, and fibers.
Propylene is usually a liquid at room temperature and is highly flammable. It has a boiling point of−47 °C, a melting point of−103 °C, and a lower explosive limit of 2. 1%. It is classified as a hydrocarbon because it contains both carbon and hydrogen atoms and is a derivative of petroleum.
Propylene is an important part of the petrochemical industry and finds extensive applications in different industries, ranging from the production of polypropylene to the usage of propylene oxide in the manufacture of polyurethanes.
Is propylene a renewable source?
No, propylene is not considered a renewable source. It is derived from a variety of non-renewable sources, such as crude oil, natural gas and coal. As a result, production of propylene is associated with a significant amount of CO2 emissions.
Additionally, the process for refining propylene from these sources is energy intensive and unsustainable in the long term.
It is possible to produce propylene from renewable sources, but not on a large scale. Renewable sources such as sugarcane and corn feedstocks can be used to produce propylene in a process called biorefining.
However, this approach is still in its infancy and faces numerous challenges in terms of improving efficiency and scaling up production.
Due to the nature of propylene production and its reliance on non-renewable resources, propylene is not a renewable source and therefore not considered a viable option for meeting the world’s energy demands.
