Glycol ethers are a group of solvents based on alkyl ethers which can be from ethylene glycol or propylene glycol (these are commonly used in paints and cleaners). 
Typically, these solvents have a higher boiling point. 

Glycol ethers are categorized as two types which are “e-series” and “p-series” depending on whether they are made from ethylene oxide or propylene oxide, respectively.
Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol commonly used in paints and cleaners. 

These solvents typically have a higher boiling point, together with the favorable solvent properties of lower-molecular weight ethers and alcohols. 
Glycol ethers, with both an ether and alcohol functional group in the same molecule, are one of the most versatile classes of organic solvents. 

Glycol ethers are either "e-series" or "p-series" glycol ethers, depending on whether they are made from ethylene oxide or propylene oxide, respectively.
Glycol ethers belong to a very common group of chemical substances known as volatile organic compounds (VOCs). 

This group of Glycol ethers includes more than 80 derivatives used in a wide range of everyday products and solvents due to their specific amphipathic physico-chemical properties (i.e. containing both hydrophilic and hydrophobic residues). 
Examples of VOCs include benzene, styrene, and toluene. 

Some of them are found in products such as water-based paints, wooden floor varnishes, cleaning products, hair dyes, cosmetic products, etc. 
About 30 of these substances are currently used in industrial applications. 

Glycol ethers can be divided into two chemical subtypes: 
The ethylene series (e.g. ethylene glycol butyl ether or EGBE, diethylene glycol butyl ether or DEGBE), and the propylene series (e.g. propylene glycol monomethyl ether or PGME). 
Most glycol ethers are water-soluble, and biodegradable.

Glycol Ethers is actively produced and traded in the US, Asia and Europe, so market participants must track activity across multiple regions to stay abreast of market dynamics. 
Supply, demand and upstream costs, as well as import/export activity, are all key drivers of this market. 
Any changes upstream, or production outages, can have a significant impact on negotiations.

The increased use of water-based surface coatings, in which Glycol ethers play an important role, has led to the growth of the entire glycol market. 
These compounds are alkyl ethers which originate from either ethylene glycol (“E-series”) or propylene glycol (“P-series”). 
Typically, these solvents have high boiling points.

Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol, also sometimes called Cellosolve. 
Glycol ethers typically have higher boiling point, together with the favorable solvent properties of lower molecular weight ethers and alcohols. 
The original Glycol ether is ethyl cellosolve.

Glycol ethers can be also derived of diethylene glycol (carbitols). 
Acetates of glycols are a similar kind of potent solvents.
Glycol ethers are water soluble & biodegradable in nature with low toxicity. 

This ether has excellent solvent properties for low molecular weight compounds including alcohol with higher boiling point. 
Glycol ethers belong to the group of solvent which is based on alkyl ethers of ethylene or propylene glycol.

Members of the CELLOSOLVE and CARBITOL solvent families are also useful chemical intermediates. 
These glycol ethers will undergo many of the same reactions as alcohols because they contain the hydroxyl (-OH) functional group. 

Some typical examples are:
Reaction with carboxylic acids, carboxylic acid chlorides, anhydrides and inorganic acids to produce esters,
Reaction with organic halides to produce ethers, such as glymes,
Reaction with alkenes and alkynes to produce ethers,

Reaction with halogenating agents to produce alkoxy alkyl halides,
Reaction with epoxides to produce polyether alcohols,
Reaction with aldehydes and ketones to produce hemiacetals and acetals.

Glycol Ethers products are produced through continuous processes of selectively reacting alcohol and ethylene oxide. 
Glycol ethers, as a class of chemicals having longer hydrocarbon-like alkoxide groups, display solubility more characteristic of hydrocarbons.

Glycol Ethers are a family of chemicals with key solvent properties used in various and diverse applications. 
Manufacturers of these chemicals are members of the Oxygen Solvents Producers Association (OSPA), a branch of the European Solvents Industry Group (ESIG) which sits under the Cefic umbrella.

Glycol ethers form a varied family of more than 30 solvents. 
All these glycol ethers have different properties – and are therefore fit for different uses.
They are an invaluable solution for industries but are also part of everyday life.

Traditionally, a distinction is made between two main groups of glycol ethers: 
E series and P series, depending on whether they are made from ethylene or propylene. 

In each group, different derivatives have been developed to provide the properties of solubility, volatility, compatibility and inflammability required for the applications.

Glycol Ethers have been used since the 1960’s as solvents and stabilizers in a variety of personal, household, and industrial products. 
The use of glycol ethers has changed significantly over the past 30 years. 

Low molecular weight E-series have been phased-out and progressively replaced by low molecular weight P-series whenever possible. 
These substances are industrial chemicals, not expected to occur naturally in the environment.
Significant changes that have influenced the entire glycol ether market during the last decade.

The growth of water-based surface coatings as replacements for solvent-based coatings: 
It seems that water-based coatings that mainly use glycol ethers as coalescing agents have been the major factor behind the growth of the entire glycol ether market.

Low molecular weight E-series (ethylene glycol derivatives) have been largely replaced with low molecular weight P-series (propylene glycol derivatives) over the last 35 years.
Glycol ethers (E series) include 2-methoxyethanol (EGME), 2-ethoxyethanol (EGEE), 2-butoxyethanol (EGBE), and their acetates. 

Glycol ethers are considered a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol. 
Glycol ethers typically have higher boiling point, together with the favorable solvent properties of lower-molecular weight ethers and alcohols.

The glycol ether product family is made up of more than 30 different types of solvents that can be categorized into two major groups, E-series and P-series, depending upon the starting material used (ethylene or propylene).

E-series comprises ethylene glycol butyl ether, ethylene glycol propyl ether, and ethylene glycol butyl ether acetate as key products. 
These are used extensively as they have strong compatibility with diverse organic solvents and water. 
Glycol ethers also have low volatility and strong solvent properties.

According to the World Bank, the construction industry expenditure in 2020 is likely to witness a growth of about 4.2% from that in 2019. 
This, in turn, is likely to increase the demand for glycol ether during the forecast period.

Glycol ethers combine the solubility characteristics of both ethers and alcohols (or esters), as both functional groups (ether and hydroxyl [or carboxyl]) are present in the molecule. 
Glycol ethers are organic solvents. 
Many different glycol ethers are used for cleaning. 

Glycol ethers are volatile organic compounds (VOCs) and may be regulated. 
Glycol ethers tend to emulsify well for cleaning and separate easily during recovery. 
One method for disposal is to burn the solvent in an approved chemical incinerator.

The global demand for glycol ethers grew significantly during 2016–18, but started to slow in 2019, with a slowdown in the automobile production.
The COVID-19 pandemic in 2020 has caused a further 15% decline in worldwide demand. 
As of 2020, the market has been described by the industry as long. 

Coatings for the construction and automotive industries have been the hardest hit, while printing inks, agrochemicals, and industrial cleaners have been somewhat less affected. 
Because of the oversupply situation, the prices of commodity glycol ethers such as EB and PM have been decreasing significantly. 

As many countries have restarted their industrial activity following the lockdowns imposed during the first half of 2020, demand for glycol ethers is expected to start recovery in 2021 and to reach the 2017 level some time before 2025.
